* Disallow invalid function names.

* Support terse mixin syntax in the indented syntax.

* Fix `@at-root` query parsing.

* Support special functions in `@-moz-document`.

* Support `...` after a digit.

## 1.0.0-alpha.7

* Fix `function-exists()`, `variable-exists()`, and `mixin-exists()` to use the
  lexical scope rather than always using the global scope.

* `str-index()` now correctly inserts at negative indices.

* Properly parse `url()`s that contain comment-like text.

* Fix a few more small `@extend` bugs.

* Fix a bug where interpolation in a quoted string was being dropped in some
  circumstances.

* Properly handle `@for` rules where each bound has a different unit.

* Forbid mixins and functions from being defined in control directives.

* Fix a superselector-computation edge case involving `:not()`.

* Gracefully handle input files that are invalid UTF-8.

* Print a Sass stack trace when a file fails to load.

## 1.0.0-alpha.6

* Allow `var()` to be passed to `rgb()`, `rgba()`, `hsl()`, and `hsla()`.

* Fix conversions between numbers with `dpi`, `dpcm`, and `dppx` units.
  Previously these conversions were inverted.

* Don't crash when calling `str-slice()` with an `$end-at` index lower than the
  `$start-at` index.

* `str-slice()` now correctly returns `""` when `$end-at` is negative and points
  before the beginning of the string.

* Interpolation in quoted strings now properly preserves newlines.

* Don't crash when passing only `$hue` or no keyword arguments to
  `adjust-color()`, `scale-color()`, or `change-color()`.

* Preserve escapes in identifiers. This used to only work for identifiers in
  SassScript.

* Fix a few small `@extend` bugs.

## 1.0.0-alpha.5

* Fix bounds-checking for `opacify()`, `fade-in()`, `transparentize()`, and

* Fix a bug where `@extend` produced the wrong result when used with
  selector combinators.

* Fix a bug where placeholder selectors were not allowed to be unified.

* Fix the `mixin-exists()` function.

* Fix `:nth-child()` and `:nth-last-child()` parsing when they contain `of
  selector`.

* Fix a bug with converting some RGB colors to HSL.

* Fix a parent selector resolution bug.

* Properly declare the arguments for `opacify()` and related functions.
