 ## [Unreleased]

 ## [0.3.1] - 2019-07-22
 ### Changed
 - Moved dependency on libm to avif executables, instead of directly on the library
 - Minor changes to README examples

 ## [0.3.0] - 2019-07-22
 ### Added
 - new CMake option `AVIF_CODEC_AOM` to enable/disable the usage of AOM's codec (default: on)
 - new CMake option `AVIF_CODEC_DAV1D` to enable/disable the usage of dav1d's codec (default: off)
 - `codec_dav1d.c`, which provides decoding via `libdav1d`
 - fuzz.sh which builds with afl-clang and runs afl-fuzz
 - aviffuzz tool, used in fuzzing script
 - fuzz inputs made with colorist
 - `.clang-format` file
 - `avifArray*()` functions for basic dynamic arrays when parsing
 - `moov` box parsing
 - now reads 'avis' brands
 - Split avifDecoderRead() into components for image sequences:
   - avifDecoderSetSource()
   - avifDecoderParse()
   - avifDecoderNextImage()
   - avifImageCopy()
   - avifDecoderReset()
 - Added decoder and image timings for image sequences

 ### Changed
 - Reorganized internal struct avifCodec to accomodate multiple codecs simultaneously (compile time; not exposed to API)
 - Fix some compiler warnings
 - Sanity check offsets and sizes in items table before using
 - Bail out of box header advertises an impossible size
 - Ran clang-format on all of src and include
 - Fix copypasta leading to a memory leak in RGB planes
 - Switched items and properties during parse to use dynamic arrays
 - Refactored codec API to not require each codec to maintain per-plane decoder instances
 - avifImage can now "not own" its planes and directly point at decoder planes to avoid copies
 - aviffuzz attempts to decode all images in source material twice (using avifDecoderReset())
 - Switch decoder->quality to explicit [minQuantizer, maxQuantizer], update assoc. constants
 - Add examples to README

 ## [0.2.0] - 2019-06-12
 ### Added
 - Added `avifEncoder` and `avifDecoder` to match `avifImage`'s pattern and allow for easier future parameterization

 ### Changed
 - Renamed project in cmake to `libavif` to match new official repo naming
 - Updated appveyor script to use `libavif`
 - Updated examples and apps to use new encoder/decoder pattern

 ## [0.1.4] - 2019-06-11
 ### Added
 - `avifPixelFormatToString()` convenience function for debugging/printing
 - `avifenc` and `avifdec` "apps" which show basic bidirectional conversion to y4m

 ### Changed
 - Make calling `avifImageYUVToRGB()` upon reading an avif optional
 - Moved `ext/aom` submodule to use official remote
 - Update `ext/aom` submodule to commit [38711e7fe](https://aomedia.googlesource.com/aom/+/38711e7fe1eff68296b0324a9809804aec359fa5)

 ### Removed
 - Remove all calls to `convertXYZToXYY()` as they were all unnecessary

 ## [0.1.3] - 2019-04-23
 ### Changed
 - `ftyp` - Change `major_brand` to `avif`
 - `ftyp` - Reorder `compatible_brands`, add `MA1A` or `MA1B` when appropriate
 - Write `meta` box before `mdat` box for streaming friendliness

 ## [0.1.2] - 2019-04-18
 ### Added
 - `AVIF_NCLX_COLOUR_PRIMARIES_P3` (convenient mirrored value)
 - `avifNclxColourPrimariesFind()` - Finds a builtin avifNclxColourPrimaries and name by a set of primaries

 ### Changed
 - Fixed enum name copypasta for `AVIF_NCLX_COLOUR_PRIMARIES_EG432_1`
 - Fix UV limited ranges when doing full<->limited range conversion

 ## [0.1.1] - 2019-04-15
 ### Added
 - Added `appveyor.yml` (exported from Appveyor)
 - Move `ext/aom` to a proper submodule
 - Update AOM to commit [3e3b9342a](https://aomedia.googlesource.com/aom/+/3e3b9342a20147ec6e4f89aa290e20277c1260ce) with minor CMake changes

 ### Changed
 - Added static library artifact zip to Windows x64 builds (Appveyor)
 - Updated README to explain libavif's goals and a little more build info
 - Fix clang warning in `avifVersion()` signature

 ## [0.1.0] - 2019-04-12
 ### Added
 - First version. Plenty of bugfixes and features await!
 - `ext/aom` based off AOM commit [3563b12b](https://aomedia.googlesource.com/aom/+/3563b12b766639ba445eb0e62a225a4419594aef) with minor CMake changes
 - An interest and willingness to maintain this file.
 - Constants `AVIF_VERSION`, `AVIF_VERSION_MAJOR`, `AVIF_VERSION_MINOR`, `AVIF_VERSION_PATCH`
 - `avifVersion()` function
