## Release 0.19.0 - 2021-03-14
Progress: 3371 of 5945 tests passed in dart-sass compatibility mode.
### Breaking changes
* The unit of a `Numeric` is now a `UnitSet` rather than a `Unit`.
* `Error` has new variants and a new field in `BadArguments`.
* A sass::Value::Call now has a source position.
* A `Rational` is now a `Ratio<i64>` rather than a `Ratio<isize>`.
### Improvements
* Added a Contributing section to readme.
* Handle values with multiple units. PR #97.
* Show call position for errors in function calls, and test for type
errors in many standard functions. Many error messages are made
identical to dart-sass, improving test-suit progress with more than
400 tests. PR #99.
* Fix issue #98: overflow in rational number arithmetic.
* Allow `@at-root` at document root.
* Boolean operators is truly lazy, e.g. `false and f($x)` does not call `f`.
* Refactored number parsing to use overflowing rationals. PR #100.
* Test suite sass-spec updated to 2021-03-02.
* Updated num-rational and num-bigint to 0.4.0.
Thanks to @alvra for reporting #98.

## Release 0.18.0 - 2021-02-25
Progress: 2892 of 5945 tests passed in dart-sass compatibility mode.
### Breaking changes
Lots of things have been moved around. See `Scope`, `Numeric`, and
`Function` in particular.
### Improvements

* Improve trigonometric precision by using f64 π rather than rational.
* Handle more peculiarities with atan2, pow, infinities and negative zero.
* Improve name lookups in scopes and modules, PR #87.
* new `struct Scope` replaces trait and three structs. PR #95.
* A color can be Hsla or Hwba as well as Rgba. PR #88, #89.
* Handle units in `@for` loops inside sass functions.
* Some types moved into `value` mod, imporoved docs. PR #90.
* Add support for `$=`, `~=` and `^=` in css attribute selectors.
Issue #91, PR #92.
* A `Numeric` is a Number with a Unit. Also hide NumValue enum. PR #93.
* The `SassFunction` type is now named `sass::Function`.
* Test suite sass-spec updated to 2021-02-18.
* Some cleanups.
Thanks to @mfeckie for #91/#92.

## Release 0.17.0 - 2021-01-29
Progress: 2784 of 5936 tests passed in dart-sass compatibility mode.
### Breaking changes
* Update nom to 6.0 raises the minimally supported compiler version
to 1.44.0. Also, the dependency is technically exposed.
* `sass::Item::Use` was modified by #84.
* `compile_scss_file` is renamed to `compile_scss_path`, and
`FileContext` is now a trait, the default implementation is renamed
to `FsFileContext` by #85.
### Improvements

`FileContext`, PR #85.
* Support the `@use name as *` syntax, PR #84.
* Make `Error::BadValue` a little closer to whats expected.
* Handle units in `@for` loops.
* Update `nom` to 6.0, PR #83.
* Update `rand` to 0.8, PR #86.
* Testing is now done with github actions rather than travis
(Appveyor remains for window builds).
* sass-spec test suite updated to 2021-01-20.

## Release 0.16.0 - 2020-11-10
Progress: 2718 of 5840 tests passed in dart-sass compatibility mode.
### Breaking changes
* `SourceName` and `sass::Item::Import` was changed by #62.
* `Use` was added to the `sass::Item` enum by #80.
* Changes to `sass::Value` and `css::Vaue` by #81.
### Improvements
* PR #80: Implement `@use` for standard sass modules. All standard
modules are at least partially supported, only `sass:string` is
fully supported. See issue #60 for for module support status.
* PR 82: Implement hwb support in `sass:color`.
Also, provide `From<Rgba>` for `css::Value` and deprecate color
value constructors.
* Provide `From<bool>` for `css::Value` (and deprecate `Value::bool(v)`).
* PR #62: Improve `ParseError`, `SourcePos`, and `SourceName` by using
located spans by [nom_locate](https://lib.rs/crates/nom_locate) in
the parser. A `sass::Item::Import` now handles where each file is
imported from, to improve error reporting.
* PR #81: Improved number handling. Now `Value::Number` handles both
machine-sized rationals, bignum rationals and floats internally and
`Value::NumberBig` is removed. Also, `Value` no longer implements
`Ord` but only `PartialOrd`, to handle f64 NaN an infinite values
correctly.
* Improve parsing of `@else` clauses.
* Update spec to 2020-10-29.

## Release 0.15.0 - 2020-10-25
Progress: 2320 of 5577 tests passed in dart-sass compatibility mode.
### Breaking changes
* The `Item::Comment` enum value now contains a `SassString` rather
than a `String`.
* The `Error::ParseError` enum value changed, and `ErrPos` is replaced
with `SourcePos` and `SourceName`.
* The error type of `parse_scss_data` changed to `ParseError`.
* `Unit::dimension()` now returns a `Dimension` rather than a `&str`.
### Improvements
* PR #79: Refactor some error handling. Relates to #46.
* Improve map parsing (a map is parsed as a plain vec of key/value
pairs, filtering duplicates happens only when it is evaluated).
* Allow multiple `&` items in the same selector.
* `&` evaluates to null when used as a value without enclosing selector.
* Implement the `@debug` directive.
* Fix `a % b` evaluation for negative values.
* Allow / ignore comments in properties and values.
* Allow `!default` and `!global` in any order on variable declarations.
* Improve `inspect(...)` formatting of list values.
* Refactor and improve arithmetic on different units.
* `ListSeparator` is now `Copy`.
* Allow interpolation in comments.
* Some refactoring

This sets the target when testing and changes some different
behavior, including how strings are parsed and handled.
* PR #75 from @divergentdave: Parse and add `Value` variants for
BigInt numbers
* PR #77: Support `rgba(r g b / a)` and `hsla(h s l / a)` functions,
i.e. the `channels` parameter with div-separated alpha channel.

sassers appears to be dead while grass is in rather active
development.
* Add a CHANGELOG.md
* Update spec to 2020-09-17.
* Update num-rational to 0.3.0.

## Release 0.13.0 - 2020-04-19
Progress: 1634 of 3502 tests passed in libsass compatibility mode.
* output::Format wraps an output::Style and a precision. The global
precision setting is removed.
* Value and other structs no longer implents Display, instead the
provid a `format` method, that takes an output format and provides a
Display implementation.
* The `compile_value` rust function now takes a format argument.
* Issue #42 (partial): The `min(..)` and `max(...)` functions are
handled as plain css functions when valid, while still handling them
as sass functions when nessecary.
* PR #69, fixing #68: Avoid exponential complexity on parenthesis.
* Allow comments in `@function` bodies.
* PR #67 from @connorskees: Refactor and fix printing of numbers
* When defining multiple variables, having more names than values is
allowed. The extra names get null values.
* Convert som panics / unwraps to properly handled errors.
* There was massive restructuring in the test suite, so almost all
tests moved around. I moved remaining tests to build a single test
program for the suite rather than several for different directories
in the suite (this also means more tests are included in the
conversion).
* Fix check_spec stats calculation.

## Release 0.11.2 - 2019-12-25
* PR #56: The url function is special.
Handle `url(foo)` as simply a string if possible. Sometimes, such
as `url("foo" + $bar)`, it must be a function returning a string
instead. Partially adresses #42. Fixes #41.

mode.
* Update `nom` to version 5.0.
* A string can start with a `#` without being a color.
* Correct parameter name for `unit`, `unitless`, `quote`, and
`unquote` functions.
* The `random` function ignores units.
* An empty unquoted string behaves like null.
* Fix some issues with string offsets in `str_slice` and `str_insert`.
* The `quote` function can use single quotes when needed.
* Return an error rather than panicing on some invalid scss.
* Some test updates and fixes in spectest.

## Release 0.10.2 - 2019-07-07
Sass-spec reports 1472 of 2802 tests passed in libsass compatibility mode.
* Update progress number in readme and documentation, since I forgot
in 0.10.0.
## Release 0.10.0 - 2019-07-07
* PR #51: Impove string parsing/escaping.
* Issue #46, PR #47: Report file position of parse errors, and improve
the parser to have errors reported in a more specific position.
* Improve error handling in functions, calling a function _can_ yield
an error. Partially solves #41: The unsupported call will now yield
an error rather than hang `rsass`.
* Commandline changes:
- Support `-I` commandline argument for include path.
- Use lowercase `-v` for version (expected by the test runner).
* Some color function improvements:
- Handle alpha percentatges in rgba.
- The rgb function can be used as rgba with four args.
- Use alpha propely when mixing colors.
- Handle both alpha and opacity css function fallback.
- Implement the grayscale function.
- Support three arguments to `rgba` function.
* Some list function improvements:
- `inspect` shows parens for empty list, and spells out `"null"` for
a null value.
- Join gets better at selecting wether result should be comma or
space separated.
- The length function treats a null as an empty list.
- Handle singleton in `index` and `nth` functions.
* More function improvements:
- Implement the `unique_id` function.
- Check that indexes are sane in `str_slice` function.
- Skip null args even if not last when evaluating a function to a
function call.
- Implement equality check for builtin functions.
* Error, not panic, on unknown mixin.
* Allow modifiers on attribute selectors.
* Color names are caseless.
* Improve handling of url imports.
* Update `deunicode` to 1.0 and `rand` to 0.7.0.
* Allow interpolation in namespacerule.
* Allow ";" after body block.
* Lots of test suite updates, including support for .hrx tests in
spectest. Target libsass compatibility in testing.
I don't really know if I should target libsass or dart-sass
compatibility, but libsass seems to be closer to my current
implementation, so target that at least for now.

Changes since version 0.8.0 includes:
* PR #24: Implement a Rgba type and use in css::Value and sass::Value.
* PR #22: Partial support for `@at-root`. Supports `&` back-refs but

## Release 0.8.0 - 2018-04-07
A default run of sass-spec found 1583 of 3364 tests passing.
Changes since version 0.7.0 includes:
* PR #17, #18, and #19 from @ErichDonGubler: Improvements to `check_spec`.
* Allow trailing comma in dictionary definition.

css::Value, and modify the call function to take such a Value. The
warning when the Value is a Literal is more motivated now.
* Add weight arg for invert function.
* If a function call fails, output it as-is.
* Allow `@include` w/o ";" to be last input.
* Use correct names for output styles. The supported styles are
`expanded` and `compressed`.
* Add maintenence status to manifest.
* Impement the `&` value, expanding to the selector containing the
value.
* Implement the `selector-parse`, `selector-append`, and
`selector-nest` functions.
* Fix AsciiExt warning on rust 1.23 and up.
* Fix #16, Do not build a no-op command line, by specifying commandline as
required-features of the bin target.
Thanks to @biluohc for the suggestion!
* Miscellaneous code cleanup, dependency updates and reformatting.
