It is now `GeneralPurpose` to + make its intended usage more clear. +- `GeneralPurpose` and its config are now `pub use`'d in the `engine` module for convenience. +- Change a few `from()` functions to be `new()`. `from()` causes confusing compiler errors because of confusion + with `From::from`, and is a little misleading because some of those invocations are not very cheap as one would + usually expect from a `from` call. +- `encode*` and `decode*` top level functions are now methods on `Engine`. +- `DEFAULT_ENGINE` was replaced by `engine::general_purpose::STANDARD` +- Predefined engine consts `engine::general_purpose::{STANDARD, STANDARD_NO_PAD, URL_SAFE, URL_SAFE_NO_PAD}` + - These are `pub use`d into `engine` as well +- The `*_slice` decode/encode functions now return an error instead of panicking when the output slice is too small + - As part of this, there isn't now a public way to decode into a slice _exactly_ the size needed for inputs that + aren't multiples of 4 tokens. If adding up to 2 bytes to always be a multiple of 3 bytes for the decode buffer is + a problem, file an issue. + +## Other changes + +- `decoded_len_estimate()` is provided to make it easy to size decode buffers correctly. + +# 0.20.0 + +## Breaking changes + +- Update MSRV to 1.57.0 +- Decoding can now either ignore padding, require correct padding, or require no padding. The default is to require + correct padding. + - The `NO_PAD` config now requires that padding be absent when decoding. + +## 0.20.0-alpha.1 + +### Breaking changes + +- Extended the `Config` concept into the `Engine` abstraction, allowing the user to pick different encoding / decoding + implementations. + - What was formerly the only algorithm is now the `FastPortable` engine, so named because it's portable (works on + any CPU) and relatively fast. + - This opens the door to a portable constant-time + implementation ([#153](https://github.com/marshallpierce/rust-base64/pull/153), + presumably `ConstantTimePortable`?) for security-sensitive applications that need side-channel resistance, and + CPU-specific SIMD implementations for more speed. + - Standard base64 per the RFC is available via `DEFAULT_ENGINE`. To use different alphabets or other settings ( + padding, etc), create your own engine instance. +- `CharacterSet` is now `Alphabet` (per the RFC), and allows creating custom alphabets. The corresponding tables that + were previously code-generated are now built dynamically. +- Since there are already multiple breaking changes, various functions are renamed to be more consistent and + discoverable. +- MSRV is now 1.47.0 to allow various things to use `const fn`. +- `DecoderReader` now owns its inner reader, and can expose it via `into_inner()`. For symmetry, `EncoderWriter` can do + the same with its writer. +- `encoded_len` is now public so you can size encode buffers precisely. + +# 0.13.1 + +- More precise decode buffer sizing, avoiding unnecessary allocation in `decode_config`. + +# 0.13.0 + +- Config methods are const +- Added `EncoderStringWriter` to allow encoding directly to a String +- `EncoderWriter` now owns its delegate writer rather than keeping a reference to it (though refs still work) + - As a consequence, it is now possible to extract the delegate writer from an `EncoderWriter` via `finish()`, which + returns `Result<W>` instead of `Result<()>`. If you were calling `finish()` explicitly, you will now need to + use `let _ = foo.finish()` instead of just `foo.finish()` to avoid a warning about the unused value. +- When decoding input that has both an invalid length and an invalid symbol as the last byte, `InvalidByte` will be + emitted instead of `InvalidLength` to make the problem more obvious. + +# 0.12.2 + +- Add `BinHex` alphabet + +# 0.12.1 + +- Add `Bcrypt` alphabet + +# 0.12.0 + +- A `Read` implementation (`DecoderReader`) to let users transparently decoded data from a b64 input source +- IMAP's modified b64 alphabet +- Relaxed type restrictions to just `AsRef<[ut8]>` for main `encode*`/`decode*` functions +- A minor performance improvement in encoding + +# 0.11.0 + +- Minimum rust version 1.34.0 +- `no_std` is now supported via the two new features `alloc` and `std`. + +# 0.10.1 + +- Minimum rust version 1.27.2 +- Fix bug in streaming encoding ([#90](https://github.com/marshallpierce/rust-base64/pull/90)): if the underlying writer + didn't write all the bytes given to it, the remaining bytes would not be retried later. See the docs + on `EncoderWriter::write`. +- Make it configurable whether or not to return an error when decoding detects excess trailing bits. + +# 0.10.0 + +- Remove line wrapping. Line wrapping was never a great conceptual fit in this library, and other features (streaming + encoding, etc) either couldn't support it or could support only special cases of it with a great increase in + complexity. Line wrapping has been pulled out into a [line-wrap](https://crates.io/crates/line-wrap) crate, so it's + still available if you need it. + - `Base64Display` creation no longer uses a `Result` because it can't fail, which means its helper methods for + common + configs that `unwrap()` for you are no longer needed +- Add a streaming encoder `Write` impl to transparently base64 as you write. +- Remove the remaining `unsafe` code. +- Remove whitespace stripping to simplify `no_std` support. No out of the box configs use it, and it's trivial to do + yourself if needed: `filter(|b| !b" \n\t\r\x0b\x0c".contains(b)`. +- Detect invalid trailing symbols when decoding and return an error rather than silently ignoring them. + +# 0.9.3 + +- Update safemem + +# 0.9.2 + +- Derive `Clone` for `DecodeError`. + +# 0.9.1 + +- Add support for `crypt(3)`'s base64 variant. + +# 0.9.0 + +- `decode_config_slice` function for no-allocation decoding, analogous to `encode_config_slice` +- Decode performance optimization + +# 0.8.0 + +- `encode_config_slice` function for no-allocation encoding + +# 0.7.0 + +- `STANDARD_NO_PAD` config +- `Base64Display` heap-free wrapper for use in format strings, etc + +# 0.6.0 + +- Decode performance improvements +- Use `unsafe` in fewer places +- Added fuzzers + +# 0.5.2 + +- Avoid usize overflow when calculating length +- Better line wrapping performance + +# 0.5.1 + +- Temporarily disable line wrapping +- Add Apache 2.0 license + +# 0.5.0 + +- MIME support, including configurable line endings and line wrapping +- Removed `decode_ws` +- Renamed `Base64Error` to `DecodeError` + +# 0.4.1 + +- Allow decoding a `AsRef<[u8]>` instead of just a `&str` + +# 0.4.0 + +- Configurable padding +- Encode performance improvements + +# 0.3.0 + +- Added encode/decode functions that do not allocate their own storage +- Decode performance improvements +- Extraneous padding bytes are no longer ignored.
