+
+### Changed
+
+- documentation fixes
+- Ci fixes
+- the move to minimal-lexical for float parsing introduced bugs that cannot be resolved right now, so this version moves back to using the standard lib' parser. *This is a performance regression**. If you have specific requirements around float parsing, you are strongly encouraged to use [recognize_float](https://docs.rs/nom/latest/nom/number/complete/fn.recognize_float.html) and another library to convert to a f32 or f64
+
+### Added
+
+- alt now works with 1 elment tuples
+
+## 7.0.0 - 2021-08-21
+
+This release fixes dependency compilation issues and strengthen the minimum supported Rust version (MSRV) policy. This is also the first release without the macros that were used since nom's beginning.

+
+### Added
+
+- `take_until1` combinator
+- more `to_owned` implementations
+- `fail`: a parser that always fail, useful as default condition in other combinators
+- text to number parsers: in the `character::streaming` and `character::complete` modules, there are parsers named `i8, u16, u32, u64, u128` and `u8 ,u16, u32, u64, u128` that recognize decimal digits and directly convert to a number in the target size (checking for max int size)
+
+### Removed
+
+- now that function combinators are the main way to write parsers, the old macro combinators are confusing newcomers. THey have been removed
+- the `BitSlice` input type from bitvec has been moved into the [nom-bitvec](https://crates.io/crates/nom-bitvec) crate. nom does not depend on bitvec now
+- regex parsers have been moved into the [nom-regex](https://crates.io/crates/nom-regex) crate. nom does not depend on regex now
+- `ErrorKind::PArseTo` was not needed anymore
+
+### Changed
+
+- relax trait bounds
+- some performance fixes
+- `split_at_position*` functions should now be guaranteed panic free
+- the `lexical-core` crate used for float parsing has now been replaced with `minimal-lexical`: the new crate is faster to compile, faster to parse, and has no dependencies
+
+### Fixed
+
+- infinite loop in `escaped` combinator
+- `many_m_n` now fails if min > max
+

+## Notable changes
+
+This release is a more polished version of nom 5, that came with a focus on
+function parsers, by relaxing the requirements: combinators will return a
+`impl FnMut` instead of `impl Fn`, allowing closures that change their context,
+and parsers can be any type now, as long as they implement the new `Parser` trait.
+That parser trait also comes with a few helper methods.
+
+Error management was often a pain point, so a lot of work went into making it easier.
+Now it integrates with `std:error::Error`, the `IResult::finish()` method allows you
+to convert to a more usable type, the `into` combinator can convert the error type
+if there's a `From` implementation, and there are more specific error traits like
+`ContextError` for the `context` combinator, and `FromExternalError` for `map_res`.
+While the `VerboseError` type and its `convert_error` function saw some changes,
+not many features ill be added to it, instead you are encouraged to build the error
+type that corresponds to your needs if you are building a language parser.
+
+This version also integrates with the excellent [bitvec](https://crates.io/crates/bitvec)
+crate for better bit level parsing. This part of nom was not great and a bit of a hack,
+so this will give better options for those parsers.
+
+At last, documentation! There are now more code examples, functions and macros that require
+specific cargo features are now clearly indicated, and there's a new `recipes` module
+containing example patterns.
+
+### Breaking changes
+
+- the minimal Rust version is now 1.44 (1.37 if building without the `alloc` or `std` features)
+- streaming parsers return the number of additional bytes they need, not the total. This was supposed to be the case everywhere, but some parsers were forgotten
+- removed the `regexp_macros` cargo feature
+- the `context` combinator is not linked to `ParseError` anymore, instead it come with its own `ContextError` trait
+- `Needed::Size` now contains a `NonZeroUsize`, so we can reduce the structure's size by 8 bytes. When upgrading, `Needed::Size(number)` can be replaced with `Needed::new(number)`
+- there is now a more general `Parser` trait, so parsers can be something else than a function. This trait also comes with combinator methods like `map`, `flat_map`, `or`. Since it is implemented on `Fn*` traits, it should not affect existing code too much
+- combinators that returned a `impl Fn` now return a `impl FnMut` to allow parser closures that capture some mutable value from the context
+- `separated_list` is now `separated_list0`
+- removed the deprecated `methods` module
+- removed the deprecated `whitespace` module
+- the default error type is now a struct (`nom::error::Error`) instead of a tuple
+- the `FromExternalError` allows wrapping the error returned by the function in the `map_res` combinator
+- renamed the `dbg!` macro to avoid conflicts with `std::dbg!`
+- `separated_list` now allows empty elements
+
+
+### Added
+
+- function version of regex parsers
+- `fill`: attempts to fill the output slice passed as argument
+- `success`: returns a value without consuming the input
+- `satisfy`: checks a predicate over the next character
+- `eof` function combinator
+- `consumed`: returns the produced value and the consumed input
+- `length_count` function combinator
+- `into`: converts a parser's output and error values if `From` implementations are available
+- `IResult::finish()`: converts a parser's result to `Result<(I, O), E>` by removing the distinction between `Error` and `Failure` and panicking on `Incomplete`
+- non macro versions of `u16`, `i32`, etc, with configurable endianness
+- `is_newline` function
+- `std::error::Error` implementation for nom's error types
+- recipes section of the documentation, outlining common patterns in nom
+- custom errors example
+- bitstream parsing with the `BitSlice` type from the bitvec crate
+- native endianness parsers
+- github actions for CI
+
+### Changed
+
+- allows lexical-core 0.7
+- number parsers are now generic over the input type
+- stabilized the `alloc` feature
+- `convert_error` accepts a type that derefs to `&str`
+- the JSON example now follows the spec better
+
+### Fixed
+- use `fold_many0c` in the `fold_many0` macro

+
+## 5.0.0 - 2019-06-24
+
+This version comes with a complete rewrite of nom internals to use functions as a base
+for parsers, instead of macros. Macros have been updated to use functions under
+the hood, so that most existing parsers will work directly or require minimal changes.
+
+The `CompleteByteSlice` and `CompleteStr` input types were removed. To get different
+behaviour related to streaming or complete input, there are different versions of some
+parsers in different submodules, like `nom::character::streaming::alpha0` and
+`nom::character::complete::alpha0`.
+
+The `verbose-errors` feature is gone, now the error type is decided through a generic
+bound. To get equivalent behaviour to `verbose-errors`, check out `nom::error::VerboseError`
+
+### Thanks
+
+- @lowenheim helped in refactoring and error management
+- @Keruspe helped in refactoring and fixing tests

+- @webholik and @Havvy for `escaped` and `escaped_transform` fixes
+- @proman21 for help on porting bits parsers
+
+### Added
+
+- the `VerboseError` type accumulates position info and error codes, and can generate a trace with span information
+- the `lexical-core` crate is now used by default (through the `lexical` compilation feature) to parse floats from text
+- documentation and code examples for all functions and macros
+
+### Changed
+
+- nom now uses functions instead of macros to generate parsers
+- macros now use the functions under the hood
+- the minimal Rust version is now 1.31
+- the verify combinator's condition function now takes its argument by reference
+- `cond` will now return the error of the parser instead of None
+- `alpha*`, `digit*`, `hex_digit*`, `alphanumeric*` now recognize only ASCII characters
+
+### Removed
+
+- deprecated string parsers (with the `_s` suffix), the normal version can be used instead
+- `verbose-errors` is not needed anymore, now the error type can be decided when writing the parsers, and parsers provided by nom are generic over the error type
+- `AtEof`, `CompleteByteSlice` and `CompleteStr` are gone, instead some parsers are specialized to work on streaming or complete input, and provided in different modules
+- character parsers that were aliases to their `*1` version: eol, alpha, digit, hex_digit, oct_digit, alphanumeric, space, multispace
+- `count_fixed` macro
+- `whitespace::sp` can be replaced by `character::complete::multispace0`
+- method combinators are now in the nom-methods crate
+- `take_until_either`, `take_until_either1`, `take_until_either_and_consume` and `take_until_either_and_consume1`: they can be replaced with `is_not` (possibly combined with something else)
+- `take_until_and_consume`, `take_until_and_consume1`: they can be replaced with `take_until` combined with `take`
+- `sized_buffer` and `length_bytes!`: they can be replaced with the `length_data` function
+- `non_empty`, `begin` and `rest_s` function
+- `cond_reduce!`, `cond_with_error!`, `closure!`, `apply`, `map_res_err!`, `expr_opt!`, `expr_res!`
+- `alt_complete`, `separated_list_complete`, `separated_nonempty_list_complete`
+

+- error conversions are more ergonomic
+- method combinators are now deprecated. They might be moved to a separate crate
+- nom now specifies Rust 1.24.1 as minimum version. This was already the case before, now it is made explicit

+
+### Breaking changes
+
+- the `IResult` type now becomes a `Result` from the standard library
+- `Incomplete` now returns the additional data size needed, not the total data size needed
+- verbose-errors is now a superset of basic errors
+- all the errors now include  the related input slice
+- the arguments from `error_position` and other such macros were swapped to be more consistent with the rest of nom
+- automatic error conversion: to fix error type inference issues, a custom error type must now implement `std::convert::From<u32>`
+- the `not!` combinator returns unit `()`
+- FindToken's calling convention was swapped
+- the `take_*` combinators are now more coherent and stricter, see commit 484f6724ea3ccb for more information
+- `many0` and other related parsers will now return `Incomplete` if the reach the end of input without an error of the child parser. They will also return `Incomplete` on an empty input
+- the `sep!` combinator for whitespace only consumes whitespace in the prefix, while the `ws!` combinator takes care of consuming the remaining whitespace
+
+### Added
+
+- the `AtEof` trait for input type: indicate if we can get more input data later (related to streaming parsers and `Incomplete` handling)
+- the `escaped*` parsers now support the `&str`input type
+- the `Failure` error variant represents an unrecoverable error, for which `alt` and other combinators will not try other branches. This error means we got in the right part of the code (like, a prefix was checked correctly), but there was an error in the following parts
+- the `CompleteByteSlice` and `CompleteStr` input types consider there will be no more refill of the input. They fixed the `Incomplete` related issues when we have all of the data
+- the `exact!()` combinator will fail if we did not consume the whole input
+- the `take_while_m_n!` combinator will match a specified number of characters
+- `ErrorKind::TakeUntilAndConsume1`
+- the `recognize_float` parser will match a float number's characters, but will not transform to a `f32` or `f64`
+- `alpha` and other basic parsers are now much stricter about partial inputs. We also introduce the  `*0` and `*1` versions of those parsers
+- `named_args` can now specify the input type as well
+- `HexDisplay` is now implemented for `&str`
+- `alloc` feature
+- the `InputTakeAtposition` trait allows specialized implementations of parsers like `take_while!`
+
+### Removed
+
+- the producers and consumers were removed
+- the `error_code` and `error_node` macros are not used anymore
+
+### Fixed
+
+- `anychar!` now works correctly with multibyte characters
+- `take_until_and_consume1!` no longer results in "no method named \`find_substring\`" and "no method named \`slice\`" compilation errors
+- `take_until_and_consume1!` returns the correct Incomplete(Needed) amount
+- `no_std` compiles properly, and nom can work with `alloc` too
+- `parse_to!` now consumes its input
+
+### Changed
+
+- `alt` and other combinators will now clone the input if necessary. If the input is already `Copy` there is no performance impact
+- the `rest` parser now works on various input types
+- `InputIter::Item` for `&[u8]` is now a `u8` directly, not a reference
+- we now use the `compile_error` macro to return a compile time error if there was a syntax issue
+- the permutation combinator now supports optional child parsers
+- the float numbers parsers have been refactored to use one common implementation that is nearly 2 times faster than the previous one
+- the float number parsers now accept more variants
+
+
+## 3.2.1 - 2017-10-27
+
+### Thanks
+
+- @ordian for `alt_complete` fixes
+- @friedm for documentation fixes
+- @kali for improving error management
+
+### Fixed
+
+- there were cases where `alt_complete` could return `Incomplete`
+
+### Added
+
+- an `into_error_kind` method can be used to transform any error to a common value. This helps when the library is included multiple times as dependency with different feature sets
+
+
+## 3.2.0 - 2017-07-24
+
+### Thanks
+
+- @jedireza for documentation fixes
+- @gmorenz for the `bytes` combinator
+- @meh for character combinator fixes for UTF-8
+- @jethrogb for avoiding move issues in `separated_list`
+
+### Changed
+
+- new layout for the main page of documentation
+- `anychar` can now work on any input type
+- `length_bytes` is now an alias for `length_data`
+
+### Fixed
+
+- `one_of`, `none_of` and `char` will now index correctly UTF-8 characters
+- the `compiler_error` macro is now correctly exported
+
+
+### Added
+
+- the `bytes` combinator transforms a bit stream back to a byte slice for child parsers
+
+## 3.1.0 - 2017-06-16
+
+### Thanks
+
+- @sdroege: implementing be_i24 and le_i24

+- `count` no longer preallocates its vector
+
+### Fixed
+
+- better type inference in alt_complete
+- `alt` should now work with whitespace parsing
+- `map` should not make type inference errors anymore
+
+### Added
+
+- be_i24 and le_i24, parsing big endian and little endian signed 24 bit integers

+
+## 3.0.0 - 2017-05-12
+
+### Thanks
+
+- Chris Pick for some `Incomplete` related refactors
+- @dbrgn for documentation fixes
+- @valarauca for adding `be_u24`
+- @ithinuel for usability fixes
+- @evuez for README readability fixes and improvements to `IResult`
+- @s3bk for allowing non-`Copy` types as input
+- @keruspe for documentation fixes
+- @0xd34d10cc for trait fixes on `InputIter`

+- @chengsun for type inference fixes in `alt`
+- @iBelieve for adding str to no_std
+- @Hywan for simplifying code in input traits
+- @azerupi for extensive documentation of `alt` and `alt_complete`
+
+### Breaking Changes
+
+- `escaped`, `separated_list` and `separated_nonempty_list` can now return `Incomplete` when necessary
+- `InputIter` does not require `AsChar` on its `Item` type anymore
+- the `core` feature that was putting nom in `no_std` mode has been removed. There is now a `std` feature, activated by default. If it is not activated, nom is in `no_std`
+- in `verbose-errors` mode, the error list is now stored in a `Vec` instead of a box based linked list
+- `chain!` has finally been removed
+
+### Changed
+
+- `Endianness` now implements `Debug`, `PartialEq`, `Eq`, `Clone` and `Copy`
+- custom input types can now be cloned if they're not `Copy`
+- the infamous 'Cannot infer type for E' error should happen less often now
+- `str` is now available in `no_std` mode
+
+### Fixed
+
+- `FileProducer` will be marked as `Eof` on full buffer
+- `named_args!` now has lifetimes that cannot conflict with the lifetimes from other arguments
+
+### Added
+
+- `be_u24`: big endian 24 bit unsigned integer parsing
+- `IResult` now has a `unwrap_or` method
+
+
+## 2.2.1 - 2017-04-03
+
+### Thanks
+
+- @Victor-Savu for formatting fixes in the README
+- @chifflier for detecting and fixing integer overflows
+- @utkarshkukreti for some performance improvements in benchmarks
+
+### Changed
+
+- when calculating how much data is needed in `IResult::Incomplete`, the addition could overflow (it is stored as a usize). This would apparently not result in any security vulnerability on release code
+
+## 2.2.0 - 2017-03-20
+
+### Thanks
+
+- @seppo0010 for fixing `named_args`
+- @keruspe for implementing or() on `IResult`, adding the option of default cases in `switch!`, adding support for `cargo-travis`
+- @timlyo for documentation fixes
+- @JayKickliter for extending `hex_u32`
+- @1011X for fixing regex integration
+- @Kerollmops for actually marking `chain!` as deprecated
+- @joliss for documentation fixes
+- @utkarshkukreti for tests refactoring and performance improvement
+- @tmccombs for documentation fixes
+
+### Added
+
+- `IResult` gets an `or()` method
+- `take_until1`, `take_until_and_consume1`, `take_till1!` and `take_till1_s!` require at least 1 character
+
+### Changed
+
+- `hex_u32` accepts uppercase digits as well
+- the character based combinators leverage the input traits
+- the whitespace parsers now work on &str and other types
+- `take_while1` returns `Incomplete` on empty input
+- `switch!` can now take a default case
+
+### Fixed
+
+- `named_args!` now imports `IResult` directly
+- the upgrade to regex 0.2 broke the regex combinators, they work now
+
+## 2.1.0 - 2017-01-27
+
+### Thanks
+
+- @nickbabcock for documentation fixes
+- @derekdreery for documentation fixes
+- @DirkyJerky for documentation fixes
+- @saschagrunert for documentation fixes
+- @lucab for documentation fixes
+- @hyone for documentation fixes
+- @tstorch for factoring `Slice`
+- @shepmaster for adding crate categories
+- @antoyo for adding `named_args!`
+
+### Added
+
+- `verify!` uses a first parser, then applies a function to check that its result satisfies some conditions
+- `named_args!` creates a parser function that can accept other arguments along with the input
+- `parse_to!` will use the `parse` method from `FromStr` to parse a value. It will automatically translate the input to a string if necessary
+- `float`, `float_s`, `double`, `double_s` can recognize floating point numbers in text
+
+### Changed
+
+- `escaped!` will now return `Incomplete` if needed
+- `permutation!` supports up to 20 child parsers
+
+## 2.0.1 - 2016-12-10
+
+Bugfix release
+
+*Warning*: there is a small breaking change, `add_error!` is renamed to `add_return_error!`. This was planned for the 2.0 release but was forgotten. This is a small change in a feature that not many people use, for a release that is not yet widely in use, so there will be no 3.0 release for that change.
+
+### Thanks
+
+- @nickbabcock for catching and fixing the `add_error!` mixup
+- @lucab for documentation fixes
+- @jtdowney for noticing that `tag_no_case!` was not working at all for byte slices
+
+### Fixed
+
+- `add_error!` has been renamed to `add_return_error!`
+- the `not!` combinator now accepts functions
+- `tag_no_case!` is now working as accepted (before, it accepted everything)
+
+
+## 2.0 - 2016-11-25
+
+The 2.0 release is one of the biggest yet. It was a good opportunity to clean up some badly named combinators and fix invalid behaviours.
+
+Since this version introduces a few breaking changes, an [upgrade documentation](https://github.com/Geal/nom/blob/master/doc/upgrading_to_nom_2.md) is available, detailing the steps to fix the most common migration issues. After testing on a set of 30 crates, most of them will build directly, a large part will just need to activate the "verbose-errors" compilation feature. The remaining fixes are documented.
+
+This version also adds a lot of interesting features, like the permutation combinator or whitespace separated formats support.
+
+### Thanks
+
+- @lu-zero for license help
+- @adamgreig for type inference fixes
+- @keruspe for documentation and example fixes, for the `IResult => Result` conversion work, making `AsChar`'s method more consistent, and adding `many_till!`
+- @jdeeny for implementing `Offset` on `&str`
+- @vickenty for documentation fixes and his refactoring of `length_value!` and `length_bytes!`
+- @overdrivenpotato for refactoring some combinators
+- @taralx for documentation fixes
+- @keeperofdakeys for fixing eol behaviour, writing documentation and adding `named_attr!`
+- @jturner314 for writing documentation
+- @bozaro for fixing compilation errors
+- @uniphil for adding a `crates.io` badge
+- @badboy for documentation fixes
+- @jugglerchris for fixing `take_s!`
+- @AndyShiue for implementing `Error` and `Display` on `ErrorKind` and detecting incorrect UTF-8 string indexing
+
+### Added
+
+- the "simple" error management system does not accumulates errors when backtracking. This is a big perf gain, and is activated by default in nom 2.0
+- nom can now work on any type that implement the traits defined in `src/traits.rs`: `InputLength`, `InputIter`, `InputTake`, `Compare`, `FindToken`, `FindSubstring`, `Slice`
+- the documentation from Github's wiki has been moved to the `doc/` directory. They are markdown files that you can build with [cargo-external-doc](https://crates.io/crates/cargo-external-doc)
+- whitespace separated format support: with the `ws!` combinator, you can automatically introduce whitespace parsers between all parsers and combinators
+- the `permutation!` combinator applies its child parsers in any order, as long as they all succeed once, and return a tuple of the results
+- `do_parse!` is a simpler alternative to `chain!`, which is now deprecated
+- you can now transform an `IResult` in a `std::result::Result`
+- `length_data!` parses a length, and returns a subslice of that length
+- `tag_no_case!` provides case independent comparison. It works nicely, without any allocation, for ASCII strings, but for UTF-8 strings, it defaults to an unsatisfying (and incorrect) comparison by lowercasing both strings
+- `named_attr!` creates functions like `named!` but can add attributes like documentation
+- `many_till!` applies repeatedly its first child parser until the second succeeds
+
+### Changed
+
+- the "verbose" error management that was available in previous versions is now activated by the "verbose-errors" compilation feature
+- code reorganization: most of the parsers were moved in separate files to make the source easier to navigate
+- most of the combinators are now independent from the input type
+- the `eof` function was replaced with the `eof!` macro
+- `error!` and `add_error!` were replaced with `return_error!` and `add_return_error!` to fix the name conflict with the log crate
+- the `offset()` method is now in the `Offset` trait
+- `length_value!` has been renamed to `length_count!`. The new `length_value!` selects a slice and applies the second parser once on that slice
+- `AsChar::is_0_to_9` is now `AsChar::is_dec_digit`
+- the combinators with configurable endianness now take an enum instead of a boolean as parameter
+
+### Fixed
+- the `count!`, `count_fixed!` and `length_*!` combinator calculate incomplete data needs correctly
+- `eol`, `line_ending` and `not_line_ending` now have a consistent behaviour that works correctly with incomplete data
+- `take_s!` didn't correctly handle the case when the slice is exactly the right length
+
+## 1.2.4 - 2016-07-20
+
+### Thanks
+- @Phlosioneer for documentation fixes
+- @sourrust for fixing offsets in `take_bits!`
+- @ChrisMacNaughton for the XFS crate
+- @pwoolcoc for `rest_s`
+- @fitzgen for more `IResult` methods
+- @gtors for the negative lookahead feature
+- @frk1 and @jeandudey for little endian float parsing
+- @jethrogb for fixing input usage in `many1`
+- @acatton for beating me at nom golf :D
+
+### Added
+- the `rest_s` method on `IResult` returns the remaining `&str` input
+- `unwrap_err` and `unwrap_inc` methods on `IResult`
+- `not!` will peek at the input and return `Done` if the underlying parser returned `Error` or `Incomplete`, without consuming the input
+- `le_f32` and `le_f64` parse little endian floating point numbers (IEEE 754)
+-
+
+### Fixed
+- documentation fixes
+- `take_bits!` is now more precise
+- `many1` inccorectly used the `len` function instead of `input_len`
+- the INI parser is simpler
+- `recognize!` had an early `return` that is removed now
+
+## 1.2.3 - 2016-05-10
+
+### Thanks
+- @lu-zero for the contribution guidelines
+- @GuillaumeGomez for fixes on `length_bytes` and some documentation
+- @Hywan for documentation and test fixes
+- @Xirdus for correct trait import issues
+- @mspiegel for the new AST example
+- @cholcombe973 for adding the `cond_with_error!` combinator
+- @tstorch for refactoring `many0!`
+- @panicbit for the folding combinators
+- @evestera for `separated_list!` fixes
+- @DanielKeep for correcting some enum imports
+
+### Added
+- Regular expression combinators starting with `re_bytes_` work on byte slices
+- example parsing arithmetic expressions to an AST
+- `cond_with_error!` works like `cond!` but will return `None` if the condition is false, and `Some(value)` if the underlying parser succeeded
+- `fold_many0!`, `fold_many1!` and `fold_many_m_n!` will take a parser, an initial value and a combining function, and fold over the successful applications of the parser
+
+### Fixed
+- `length_bytes!` converts the result of its child parser to usize
+- `take_till!` now imports `InputLength` instead of assuming it's in scope
+- `separated_list!` and `separated_nonempty_list!` will not consume the separator if there's no following successfully parsed value
+- no more warnings on build
+
+### Changed
+- simpler implementation of `many0!`
+
+## 1.2.2 - 2016-03-09
+
+### Thanks
+- @conradev for fixing `take_until_s!`
+- @GuillaumeGomez for some documentation fixes
+- @frewsxcv for some documentation fixes
+- @tstorch for some test refactorings
+
+### Added
+- `nom::Err` now implements `std::error::Error`
+
+### Fixed
+- `hex_u32` does not parses more than 8 chars now
+- `take_while!` and `take_while1!` will not perturb the behaviour of `recognize!` anymore
+
+## 1.2.1 - 2016-02-23
+
+### Thanks
+- @sourrust for adding methods to `IResult`
+- @tstorch for the test refactoring, and for adding methods to `IResult` and `Needed`
+- @joelself for fixing the method system
+
+### Added
+
+- mapping methods over `IResult` and `Needed`
+
+### Changed
+
+- `apply_rf` is renamed to `apply_m`. This will not warrant a major version, since it is part missing from the methods feture added in the 1.2.0 release
+- the `regexp_macros` feature that used `regex!` to precompile regular expressions has been replaced by the normal regex engine combined with `lazy_static`
+
+### Fixed
+
+- when a parser or combinator was returning an empty buffer as remaining part, it was generating one from a static empty string. This was messing with buffer offset calculation. Now, that empty slice is taken like this: `&input[input.len()..]`.
+- The `regexp_macros` and `no_std` feature build again and are now tested with Travis CI
+
+## 1.2.0 - 2016-02-08
+
+### Thanks
+- @zentner-kyle for type inference fixes
+- @joelself for his work on `&str` parsing and method parsers
+- @GuillaumeGomez for implementing methods on `IResult`
+- @dirk for the `alt_complete!` combinator
+- @tstorch for a lot of refactoring work and unit tests additions
+- @jansegre for the hex digit parsers
+- @belgum for some documentation fixes
+- @lwandrebeck for some documentation fixes and code fixes in `hex_digit`
+
+### Added
+- `take_until_and_consume_s!` for consumption of string data until a tag
+- more function patterns in `named!`. The error type can now be specified
+- `alt_complete!` works like the `alt!` combinator, but tries the next branch if the current one returned `Incomplete`, instead of returning directly
+- more unit tests for a lot of combinators
+- hexadecimal digit parsers
+- the `tuple!` combinator takes a list of parsers as argument, and applies them serially on the input. If all of them are successful, it willr eturn a tuple accumulating all the values. This combinator will (hopefully) replace most uses of `chain!`
+- parsers can now be implemented as a method for a struct thanks to the `method!`, `call_m!` and `apply_rf!` combinators
+
+### Fixed
+- there were type inference issues in a few combinators. They will now be easier to compile
+- `peek!` compilation with bare functions
+- `&str` parsers were splitting data at the byte level, not at the char level, which can result in inconsistencies in parsing UTF-8 characters. They now use character indexes
+- some method implementations were missing on `IResult<I,O,E>` (with specified error type instead of implicit)
+
+## 1.1.0 - 2016-01-01
+
+This release adds a lot of features related to `&str` parsing. The previous versions
+were focused on `&[u8]` and bit streams parsing, but there's a need for more text
+parsing with nom. The parsing functions like `alpha`, `digit` and others will now
+accept either a `&[u8]` or a `&str`, so there is no breaking change on that part.
+
+There are also a few performance improvements and documentation fixes.
+
+### Thanks
+- @Binero for pushing the work on `&str` parsing
+- @meh for fixing `Option` and `Vec` imports
+- @hoodie for a documentation fix
+- @joelself for some documentation fixes
+- @vberger for his traits magic making nom functions more generic
+
+### Added
+
+- string related parsers: `tag_s!`, `take_s!`, `is_a_s!`, `is_not_s!`, `take_while_s!`, `take_while1_s!`, `take_till_s!`
+- `value!` is a combinator that always returns the same value. If a child parser is passed as second argument, that value is returned when the child parser succeeds
+
+### Changed
+
+- `tag!` will now compare even on partial input. If it expects "abcd" but receives "ef", it will now return an `Error` instead of `Incomplete`
+- `many0!` and others will preallocate a larger vector to avoid some copies and reallocations
+- `alpha`, `digit`, `alphanumeric`, `space` and `multispace` now accept as input a `&[u8]` or a `&str`. Additionally, they return an error if they receive an empty input
+- `take_while!`, `take_while1!`, `take_while_s!`, `take_while1_s!` wilreturn an error on empty input
+
+### Fixed
+
+- if the child parser of `many0!` or `many1!` returns `Incomplete`, it will return `Incomplete` too, possibly updating the needed size
+- `Option,` `Some`, `None` and `Vec` are now used with full path imports
+
+## 1.0.1 - 2015-11-22
+
+This releases makes the 1.0 version compatible with Rust 1.2 and 1.3
+
+### Thanks
+- @steveklabnik for fixing lifetime issues in Producers and Consumers
+
+## 1.0.0 - 2015-11-16
+
+Stable release for nom. A lot of new features, a few breaking changes
+
+### Thanks
+- @ahenry for macro fixes
+- @bluss for fixing documentation
+- @sourrust for cleaning code and debugging the new streaming utilities
+- @meh for inline optimizations
+- @ccmtaylor for fixing function imports
+- @soro for improvements to the streaming utilities
+- @breard-r for catching my typos
+- @nelsonjchen for catching my typos too
+- @divarvel for hex string parsers
+- @mrordinaire for the `length_bytes!` combinator
+
+### Breaking changes
+- `IResult::Error` can now use custom error types, and is generic over the input type
+- Producers and consumers have been replaced. The new implementation uses less memory and integrates more with parsers
+- `nom::ErrorCode` is now `nom::ErrorKind`
+- `filter!` has been renamed to `take_while!`
+- `chain!` will count how much data is consumed and use that number to calculate how much data is needed if a parser returned `Incomplete`
+- `alt!` returns `Incomplete` if a child parser returned `Incomplete`, instead of skipping to the next parser
+- `IResult` does not require a lifetime tag anymore, yay!
+
+### Added
+
+- `complete!` will return an error if the child parser returned `Incomplete`
+- `add_error!` will wrap an error, but allow backtracking
+- `hex_u32` parser
+
+### Fixed
+- the behaviour around `Incomplete` is better for most parsers now
+
+## 0.5.0 - 2015-10-16
+
+This release fixes a few issues and stabilizes the code.
+
+### Thanks
+- @nox for documentation fixes
+- @daboross for linting fixes
+- @ahenry for fixing `tap!` and extending `dbg!` and `dbg_dmp!`
+- @bluss for tracking down and fixing issues with unsafe code
+- @meh for inlining parser functions
+- @ccmtaylor for fixing import of `str::from_utf8`
+
+### Fixed
+- `tap!`, `dbg!` and `dbg_dmp!` now accept function parameters
+
+### Changed
+- the type used in `count_fixed!` must be `Copy`
+- `chain!` calculates how much data is needed if one of the parsers returns `Incomplete
+- optional parsers in `chain!` can return `Incomplete`
+
+## 0.4.0 - 2015-09-08
+
+Considering the number of changes since the last release, this version can contain breaking changes, so the version number becomes 0.4.0. A lot of new features and performance improvements!
+
+### Thanks
+- @frewsxcv for documentation fixes
+- @ngrewe for his work on producers and consumers
+- @meh for fixes on `chain!` and for the `rest` parser
+- @daboross for refactoring `many0!` and `many1!`
+- @aleksander for the `switch!` combinator idea
+- @TechnoMancer for his help with bit level parsing
+- @sxeraverx for pointing out a bug in `is_a!`
+
+### Fixed
+- `count_fixed!` must take an explicit type as argument to generate the fixed-size array
+- optional parsing behaviour in `chain!`
+- `count!` can take 0 elements
+- `is_a!` and `is_not!` can now consume the whole input
+
+### Added
+- it is now possible to seek to the end of a `MemProducer`
+- `opt!` returns `Done(input, None)` if `the child parser returned `Incomplete`
+- `rest` will return the remaining input
+- consumers can now seek to and from the end of input
+- `switch!` applies a first parser then matches on its result to choose the next parser
+- bit-level parsers

+- regular expression parsers
+- implementation of `take_till!`, `take_while!` and `take_while1!`
+
+### Changed
+- `alt!` can return `Incomplete`
+- the error analysis functions will now take references to functions instead of moving them
+- performance improvements on producers
+- performance improvement for `filter!`
+- performance improvement for `count!`: a `Vec` of the right size is directly allocated
+
+## 0.3.11 - 2015-08-04
+
+### Thanks
+- @bluss for remarking that the crate included random junk lying non committed in my local repository
+
+### Fixed
+- cleanup of my local repository will ship less files in the crates, resulting in a smaller download
+
+## 0.3.10 - 2015-08-03
+
+### Added
+
+- `bits!` for bit level parsing. It indicates that all child parsers will take a `(&[u8], usize)`as input, with the second parameter indicating the bit offset in the first byte. This allows viewing a byte slice as a bit stream. Most combinators can be used directly under `bits!`
+- `take_bits!` takes an integer type and a number of bits, consumes that number of bits and updates the offset, possibly by crossing byte boundaries
+- bit level parsers are all written in `src/bits.rs`
+
+### Changed
+
+- Parsers that specifically handle bytes have been moved to src/bytes.rs`. This applies to `tag!`, `is_not!`, `is_a!`, `filter!`, `take!`, `take_str!`, `take_until_and_consume!`, `take_until!`, `take_until_either_and_consume!`, `take_until_either!`
+
+## 0.3.9 - 2015-07-20
+
+### Thanks
+- @badboy for fixing `filter!`
+- @idmit for some documentation fixes
+
+### Added
+- `opt_res!` applies a parser and transform its result in a Result. This parser never fails
+- `cond_reduce!` takes an expression as parameter, applies the parser if the expression is true, and returns an error if the expression is false
+- `tap!` pass the result of a parser to a block to manipulate it, but do not affect the parser's result
+- `AccReader` is a Read+BufRead that supports data accumulation and partial consumption. The `consume` method must be called afterwardsto indicate how much was consumed
+- Arithmetic expression evaluation and parsing example
+- `u16!`, `u32!`, `u64!`, `i16!`, `i32!`, `i64!` take an expression as parameter, if the expression is true, apply the big endian integer parser, if false, the little endian version
+- type information for combinators. This will make the documentation a bit easier to navigate
+
+### Fixed
+- `map_opt!` and `map_res!` had issues with argument order due to bad macros
+- `delimited!` did not compile for certain combinations of arguments
+- `filter!` did not return a byte slice but a fixed array
+
+## 0.3.8 - 2015-07-03
+
+### Added
+- code coverage is now calculated automatically on Travis CI
+- `Stepper`: wrap a `Producer`, and call the method `step` with a parser. This method will buffer data if there is not enough, apply the parser if there is, and keep the rest of the input in memory for the next call
+- `ReadProducer`: takes something implementing `Read`, and makes a `Producer` out of it
+
+### Fixed
+- the combinators `separated_pair!` and `delimited!` did not work because an implementation macro was not exported
+- if a `MemProducer` reached its end, it should always return `Eof`
+- `map!` had issues with argument matching
+
+## 0.3.7 - 2015-06-24
+
+### Added
+- `expr_res!` and `expr_opt!` evaluate an expression returning a Result or Opt and convert it to IResult
+- `AsBytes` is implemented for fixed size arrays. This allows `tag!([41u8, 42u8])`
+
+### Fixed
+- `count_fixed!` argument parsing works again
+
+## 0.3.6 - 2015-06-15
+
+### Added
+- documentation for a few functions
+- the consumer trait now requires the `failed(&self, error_code)` method in case of parsing error
+- `named!` now handles the alternative `named!(pub fun_name<OutputType>, ...)`
+
+### Fixed
+- `filter!` now returns the whole input if the filter function never returned false
+- `take!` casts its argument as usize, so it can accepts any integer type now
+
+## 0.3.5 - 2015-06-10
+
+### Thanks
+- @cmr for some documentation fixes
+
+### Added
+- `count_fixed!` returns a fixed array
+
+### Fixed
+- `count!` is back to the previous behaviour, returning a `Vec` for sizes known at runtime
+
+### Changed
+- functions and traits exported from `nom::util` are now directly in `nom::`
+
+## 0.3.4 - 2015-06-09
+
+### Thanks
+- @andrew-d for fixes on `cond!`
+- @keruspe for features in `chain!`
+
+### Added
+- `chain!` can now have mutable fields
+
+### Fixed
+- `cond!` had an infinite macro recursion
+
+### Changed
+- `chain!` generates less code now. No apprent compilation time improvement
+
+## 0.3.3 - 2015-06-09
+
+### Thanks
+- @andrew-d for the little endian signed integer parsers
+- @keruspe for fixes on `count!`
+
+### Added
+- `le_i8`, `le_i16`, `le_i32`, `le_i64`: little endian signed integer parsers
+
+### Changed
+- the `alt!` parser compiles much faster, even with more than 8 branches
+- `count!` can now return a fixed size array instead of a growable vector
+
+## 0.3.2 - 2015-05-31
+
+### Thanks
+- @keruspe for the `take_str` parser and the function application combinator
+
+### Added
+- `take_str!`: takes the specified number of bytes and return a UTF-8 string
+- `apply!`: do partial application on the parameters of a function
+
+### Changed
+- `Needed::Size` now contains a `usize` instead of a `u32`
+
+## 0.3.1 - 2015-05-21
+
+### Thanks
+- @divarvel for the big endian signed integer parsers
+
+### Added
+- `be_i8`, `be_i16`, `be_i32`, `be_i64`: big endian signed integer parsers
+- the `core` feature can be passed to cargo to build with `no_std`
+- colored hexdump can be generated from error chains
+
+## 0.3.0 - 2015-05-07
+
+### Thanks
+- @filipegoncalves for some documentation and the new eof parser
+- @CrimsonVoid for putting fully qualified types in the macros
+- @lu_zero for some documentation fixes
+
+### Added
+- new error types that can contain an error code, an input slice, and a list of following errors
+- `error!` will cut backtracking and return directly from the parser, with a specified error code
+- `eof` parser, successful if there is no more input
+- specific error codes for the parsers provided by nom
+
+### Changed
+- fully qualified types in macros. A lot of imports are not needed anymore
+
+### Removed
+- `FlatMap`, `FlatpMapOpt` and `Functor` traits (replaced by `map!`, `map_opt!` and `map_res!`)
+
+## 0.2.2 - 2015-04-12
+
+### Thanks
+- @filipegoncalves and @thehydroimpulse for debugging an infinite loop in many0 and many1
+- @thehydroimpulse for suggesting public named parsers
+- @skade for removing the dependency on the collections gate
+
+### Added
+- `named!` can now declare public functions like this: `named!(pub tst, tag!("abcd"));`
+- `pair!(X,Y)` returns a tuple `(x, y)`
+- `separated_pair!(X, sep, Y)` returns a tuple `(x, y)`
+- `preceded!(opening, X)` returns `x`
+- `terminated!(X, closing)` returns `x`
+- `delimited(opening, X, closing)` returns `x`
+- `separated_list(sep, X)` returns a `Vec<X>`
+- `separated_nonempty_list(sep, X)` returns a `Vec<X>` of at list one element
+
+### Changed
+- `many0!` and `many1!` forbid parsers that do not consume input
+- `is_a!`, `is_not!`, `alpha`, `digit`, `space`, `multispace` will now return an error if they do not consume at least one byte
+
+## 0.2.1 - 2015-04-04
+
+### Thanks
+- @mtsr for catching the remaining debug println!
+- @jag426 who killed a lot of warnings
+- @skade for removing the dependency on the core feature gate
+
+
+### Added
+- little endian unsigned int parsers le_u8, le_u16, le_u32, le_u64
+- `count!` to apply a parser a specified number of times
+- `cond!` applies a parser if the condition is met
+- more parser development tools in `util::*`
+
+### Fixed
+- in one case, `opt!` would not compile
+
+### Removed
+- most of the feature gates are now removed. The only one still needed is `collections`
+
+## 0.2.0 - 2015-03-24
+*works with `rustc 1.0.0-dev (81e2396c7 2015-03-19) (built 2015-03-19)`*
+
+### Thanks
+- Ryman for the AsBytes implementation
+- jag426 and jaredly for documentation fixes
+- eternaleye on #rust IRC for his help on the new macro syntax
+
+### Changed
+- the AsBytes trait improves readability, no more b"...", but "..." instead
+- Incomplete will now hold either Needed;;Unknown, or Needed::Size(u32). Matching on Incomplete without caring for the value is done with `Incomplete(_)`, but if more granularity is mandatory, `Needed` can be matched too
+- `alt!` can pass the result of the parser to a closure
+- the `take_*` macros changed behaviour, the default case is now not to consume the separator. The macros have been renamed as follows: `take_until!` -> `take_until_and_consume!`, `take_until_and_leave!` -> `take_until!`, `take_until_either_and_leave!` -> `take_until_either!`, `take_until_either!` -> `take_until_either_and_consume!`
+
+### Added
+- `peek!` macro: matches the future input but does not consume it
+- `length_value!` macro: the first argument is a parser returning a `n` that can cast to usize, then applies the second parser `n` times. The macro has a variant with a third argument indicating the expected input size for the second parser
+- benchmarks are available at https://github.com/Geal/nom_benchmarks
+- more documentation
+- **Unnamed parser syntax**: warning, this is a breaking change. With this new syntax, the macro combinators do not generate functions anymore, they create blocks. That way, they can be nested, for better readability. The `named!` macro is provided to create functions from parsers. Please be aware that nesting parsers comes with a small cost of compilation time, negligible in most cases, but can quickly get to the minutes scale if not careful. If this happens, separate your parsers in multiple subfunctions.
+- `named!`, `closure!` and `call!` macros used to support the unnamed syntax
+- `map!`, `map_opt!` and `map_res!` to combine a parser with a normal function, transforming the input directly, or returning an `Option` or `Result`
+
+### Fixed
+- `is_a!` is now working properly
+
+### Removed
+- the `o!` macro does less than `chain!`, so it has been removed
+- the `fold0!` and `fold1!` macros were too complex and awkward to use, the `many*` combinators will be useful for most uses for now
+
+## 0.1.6 - 2015-02-24
+### Changed
+- consumers must have an end method that will be called after parsing
+
+### Added
+- big endian unsigned int and float parsers: be_u8, be_u16, be_u32, be_u64, be_f32, be_f64
+- producers can seek
+- function and macros documentation
+- README documentation
+### Fixed
+- lifetime declarations
+- tag! can return Incomplete
+
+## 0.1.5 - 2015-02-17
+### Changed
+- traits were renamed: FlatMapper -> FlatMap, Mapper -> FlatMapOpt, Mapper2 -> Functor
+
+### Fixed
+- woeks with rustc f1bb6c2f4
+
+## 0.1.4 - 2015-02-17
+### Changed
+- the chaining macro can take optional arguments with '?'
+
+## 0.1.3 - 2015-02-16
+### Changed
+- the chaining macro now takes the closure at the end of the argument list
+
+## 0.1.2 - 2015-02-16
+### Added
+- flat_map implementation for <&[u8], &[u8]>
+- chaining macro
+- partial MP4 parser example
+
+
+## 0.1.1 - 2015-02-06
+### Fixed
+- closure syntax change
