# Change Log
All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](http://keepachangelog.com/)
and this project adheres to [Semantic Versioning](http://semver.org/).

## [Unreleased]

## [0.2.0] - 2020-07-25
### Ported
- All complex shapers.
- Tables: `CBDT`, `CFF`, `CFF2`, `HVAR`, `MVAR`, `OS/2`, `SVG`, `VORG`, `VVAR`,
  `avar`, `cmap`, `fvar`, `glyf`, `gvar`, `hhea`, `hmtx`, `post`, `sbix`, `vhea`, `vmtx`.
- `hb_buffer_t`
- `hb_script_t`
- `hb_feature_t`
- `hb_variation_t`
- `hb_language_t`
- `hb_font_t`
- `hb-ot-metrics`
- Unicode functions and tables.
- Buffer serialization.

### Changed
- Update to HarfBuzz 2.7.0
- Rename `Font::from_data` into `Font::from_slice`.
- Font is parsed via `ttf-parser` first.
  And if the parsing fails, the `Font` will not be created.
  `harfbuzz` allows malformed fonts.

### Removed
- `hb_font_funcs_t`. Only the embedded TrueType implementation is used.
- `hb_unicode_funcs_t`. Only the embedded Unicode implementation is used.
- `Font::set_scale`/`hb_font_set_scale`/`--font-size`. Shaping is always in font units now.
  This simplifies the code quite a lot.
- Shaping plan caching.
- Fallback shaper.
- Unused `hdmx` table.

## [0.1.1] - 2020-07-04
### Fixed
- Compilation with an old XCode.

## 0.1.0 - 2020-07-04
At this point, this is just a simple Rust bindings to a stripped down harfbuzz.

### Added
- An absolute minimum Rust API.
- harfbuzz's shaping test suite had been ported to Rust.

### Changed
- harfbuzz source code was reformatted using clang-format.

### Removed
- Subsetting. This is probably a bit controversial, but I want to port only the shaper for now.
  This is also removes around 7000 LOC.
- Arabic fallback shaper. Since it requires subsetting.
- Unused TrueType tables: BASE, COLR, CPAL, JSTF, MATH, STAT, bsln, fdsc, gasp, just, lcar, ltag, meta, name, opbd.
- All external dependencies: coretext, directwrite, freetype, gdi, glib, gobject, graphite, icu, uniscribe.
  Embedded harfbuzz relies only on internal TrueType implementation.
- Most of the non-shaping harfbuzz API.
