-# v1.0.4 (2020-7-31)
-
-* `SpanRange` facility is now public.
-* Docs have been improved.
-* Introduced the `syn-error` feature so you can opt-out from the `syn` dependency.
-
-# v1.0.3 (2020-6-26)
-
-* Corrected a few typos.
-* Fixed the `emit_call_site_warning` macro.
-
-# v1.0.2 (2020-4-9)
-
-* An obsolete note was removed from documentation.
-
-# v1.0.1 (2020-4-9)
-
-* `proc-macro-hack` is now well tested and supported. Not sure about `proc-macro-nested`,
-  please fill a request if you need it.
-* Fixed `emit_call_site_error`.
-* Documentation improvements.
-
-# v1.0.0 (2020-3-25)
-
-I believe the API can be considered stable because it's been a few months without
-breaking changes, and I also don't think this crate will receive much further evolution.
-It's perfect, admit it.
-
-Hence, meet the new, stable release!
-
-### Improvements
-
-* Supported nested `#[proc_macro_error]` attributes. Well, you aren't supposed to do that,
-  but I caught myself doing it by accident on one occasion and the behavior was... surprising.
-  Better to handle this smooth.
-
-# v0.4.12 (2020-3-23)
-
-* Error message on macros' misuse is now a bit more understandable.
-
-# v0.4.11 (2020-3-02)
-
-* `build.rs` no longer fails when `rustc` date could not be determined,
-  (thanks to [`Fabian Möller`](https://gitlab.com/CreepySkeleton/proc-macro-error/issues/8)
-  for noticing and to [`Igor Gnatenko`](https://gitlab.com/CreepySkeleton/proc-macro-error/-/merge_requests/25)
-  for fixing).
-
-# v0.4.10 (2020-2-29)
-
-* `proc-macro-error` doesn't depend on syn\[full\] anymore, the compilation
-  is \~30secs faster.
-
-# v0.4.9 (2020-2-13)
-
-* New function: `append_dummy`.
-
-# v0.4.8 (2020-2-01)
-
-* Support for children messages
-
-# v0.4.7 (2020-1-31)
-
-* Now any type that implements `quote::ToTokens` can be used instead of spans.
-  This allows for high quality error messages.
-
-# v0.4.6 (2020-1-31)
-
-* `From<syn::Error>` implementation doesn't lose span info anymore, see
-  [#6](https://gitlab.com/CreepySkeleton/proc-macro-error/issues/6).
-
-# v0.4.5 (2020-1-20)
-Just a small intermediate release.
-
-* Fix some bugs.
-* Populate license files into subfolders.
-
-# v0.4.4 (2019-11-13)
-* Fix `abort_if_dirty` + warnings bug
-* Allow trailing commas in macros
-
-# v0.4.2 (2019-11-7)
-* FINALLY fixed `__pme__suggestions not found` bug
-
-# v0.4.1 (2019-11-7) YANKED
-* Fixed `__pme__suggestions not found` bug
-* Documentation improvements, links checked
-
-# v0.4.0 (2019-11-6) YANKED
-
-## New features
-* "help" messages that can have their own span on nightly, they
-    inherit parent span on stable.
-    ```rust
-    let cond_help = if condition { Some("some help message") else { None } };
-    abort!(
-        span, // parent span
-        "something's wrong, {} wrongs in total", 10; // main message
-        help = "here's a help for you, {}", "take it"; // unconditional help message
-        help =? cond_help; // conditional help message, must be Option
-        note = note_span => "don't forget the note, {}", "would you?" // notes can have their own span but it's effective only on nightly
-    )
-    ```
-* Warnings via `emit_warning` and `emit_warning_call_site`. Nightly only, they're ignored on stable.
-* Now `proc-macro-error` delegates to `proc_macro::Diagnostic` on nightly.
-
-## Breaking changes
-* `MacroError` is now replaced by `Diagnostic`. Its API resembles `proc_macro::Diagnostic`.
-* `Diagnostic` does not implement `From<&str/String>` so `Result<T, &str/String>::abort_or_exit()`
-    won't work anymore (nobody used it anyway).
-* `macro_error!` macro is replaced with `diagnostic!`.
-
-## Improvements
-* Now `proc-macro-error` renders notes exactly just like rustc does.
-* We don't parse a body of a function annotated with `#[proc_macro_error]` anymore,
-  only looking at the signature. This should somewhat decrease expansion time for large functions.
-
-# v0.3.3 (2019-10-16)
-* Now you can use any word instead of "help", undocumented.
-
-# v0.3.2 (2019-10-16)
-* Introduced support for "help" messages, undocumented.
-
-# v0.3.0 (2019-10-8)
-
-## The crate has been completely rewritten from scratch!
-
-## Changes (most are breaking):
-* Renamed macros:
-  * `span_error` => `abort`
-  * `call_site_error` => `abort_call_site`
-* `filter_macro_errors` was replaced by `#[proc_macro_error]` attribute.
-* `set_dummy` now takes `TokenStream` instead of `Option<TokenStream>`
-* Support for multiple errors via `emit_error` and `emit_call_site_error`
-* New `macro_error` macro for building errors in format=like style.
-* `MacroError` API had been reconsidered. It also now implements `quote::ToTokens`.
-
-# v0.2.6 (2019-09-02)
-* Introduce support for dummy implementations via `dummy::set_dummy`
-* `multi::*` is now deprecated, will be completely rewritten in v0.3
-
-# v0.2.0 (2019-08-15)
-
-## Breaking changes
-* `trigger_error` replaced with `MacroError::trigger` and `filter_macro_error_panics`
-  is hidden from docs.
-  This is not quite a breaking change since users weren't supposed to use these functions directly anyway.
-* All dependencies are updated to `v1.*`.
-
-## New features
-* Ability to stack multiple errors via `multi::MultiMacroErrors` and emit them at once.
-
-## Improvements
-* Now `MacroError` implements `std::fmt::Display` instead of `std::string::ToString`.
-* `MacroError::span` inherent method.
-* `From<MacroError> for proc_macro/proc_macro2::TokenStream` implementations.
-* `AsRef/AsMut<String> for MacroError` implementations.
-
-# v0.1.x (2019-07-XX)
-
-## New features
-* An easy way to report errors inside within a proc-macro via `span_error`,
-  `call_site_error` and `filter_macro_errors`.
