## [Unreleased]

## [0.9.1] - 2021-05-19

### Added
* Added strict mode/flags (enabled by default): `AVIF_STRICT_PIXI_REQUIRED`, `AVIF_STRICT_CLAP_VALID`
* avifdec: Added `--no-strict` to disable all strict flags
* avifdec: Added `-r` (`--raw-color`), which avoids multiplying against AVIF alpha channel before packing into non-alpha formats (JPEG)
* avifenc: Recognize the Y4M format string "C420mpeg2"
* avifenc: Add `--crop` convenient alternative arg to the difficult-to-use `--clap` arg
* avifenc: New default for `--yuv`: `"auto"`, which will use a source JPEG's internal YUV format instead of YUV444, if detected
* Uses: Prevent colorspace conversion when reading from JPEG if possible (tongyuantongyu)
* avifenc/avifdec: Add helpful values/calculations when dumping clap box
* Added avifDiagnostics, which allows for a detailed, freeform error string upon decode error
* Create helper avifCropRect struct and methods for helping to manipulate/populate/validate avifCleanApertureBox
* Added ability to set codec-specific options for color or alpha only
* Support for libaom's ALL_INTRA mode (if available)
* Create avifDecoder.imageCountLimit as a sanity check against malformed files
* SVT: Image sequence encoding support (tongyuantongyu)
* Added rav1e to AppVeyor builds

### Changed
* avifenc/avifdec: Link AOM_LIBRARIES and use CXX if vmaf is present (1480c1)
* Ensure that an AVIF has a ftyp box, and based on ftyp, has other appropriate toplevel boxes present as well
* Avoid linking against libyuv if it is too old / incompatible
* Always require a primary item when decoding items
* Add some strictness around ipma box parsing (version/flags tuples must be unique across ipma boxes in a file)
* Fix alpha grids by properly writing alpha grid metadata payload
* A HandlerBox (hdlr) of type 'pict' must be the first box within the MetaBox (meta)
* Add some typedefs for various flag decls in avif.h to self-document which flags should be used in which function arguments
* When encoding single-frame images using libaom, clean up the encoder immediately after encoding the frame to cut down on resources high watermarks
* Fail on reformat Identity (MC=0) with subsampling (not using YUV444)
* Warn if alpha is limited range (deprecated)
* Validate the first_chunk fields in the stsc box
* In libaom all intra mode, set cq-level for user
* Check the return values of some aom_codec_ calls and add diagnostics output (wantehchang)
* Use aom_codec_set_option() if available (allows for future compat with libaom 3.0+ advanced features)
* rav1e: Use cargo cinstall in local builds to ensure consistency in target output, as cbuild no longer builds directly into target/release
* Tweaks to compiler flags (analyze related)
* Use libyuv BT.709 & 2020 full range YuvConstants (wantehchang)
* Multiply color with alpha for opaque RGB format during conversion (see #520)
* switch docker to ubuntu 20.04, fix tzdata install (paskal)

* Added an "Understanding maxThreads" explanatory comment block in avif.h
* Minor fixes to support AVIF_CODEC_AOM_ENCODE
* Various minor code/comments cleanup
* CI tweaks, macOS build, and caching / speed increases (EwoutH)
* Update aom.cmd: v3.1.0
* Update dav1d.cmd: 0.9.0
* Update libgav1: v0.16.3
* Update libyuv.cmd: 2f0cbb9
