This file includes a list of high level updates for each milestone release.

-----

Milestone 79

  * Make the size of program/pipeline caches configurable via
    GrContextOptions::fRuntimeProgramCacheSize
    https://review.skia.org/239756

Milestone 78

  * Added RELEASE_NOTES.txt file
    https://review.skia.org/229760

  * SkDrawLooper is no longer supported in SkPaint or SkCanvas.
    https://review.skia.org/230579
    https://review.skia.org/231736

  * SkPath::Iter::next() now ignores its consumDegenerates bools. Those will so
    go away entirely
    https://review.skia.org/235104

  * SkImage: new factories: DecodeToRaster, DecodeToTexture
    https://review.skia.org/234476

  * SkImageFilter API refactor started:
    - Provide new factory API in include/effects/SkImageFilters
    - Consolidated enum types to use SkTileMode and SkColorChannel
    - Hide filter implementation classes
    - Hide previously public functions on SkImageFilter that were intended for
      internal use only
    https://review.skia.org/230198
    https://review.skia.org/230876
    https://review.skia.org/231256

  * SkColorFilters::HSLAMatrix - new matrix color filter operating in HSLA
    space.
    https://review.skia.org/231736

  * Modify GrBackendFormat getters to not return internal pointers. Use an enum
    class for GL formats.
    https://review.skia.org/233160

  * Expose GrContext::dump() when SK_ENABLE_DUMP_GPU is defined.
    https://review.skia.org/233557

  * Vulkan backend now supports YCbCr sampler for I420 Vulkan images that are
    not backed by external images.
    https://review.skia.org/233776

  * Add SkCodec::SelectionPolicy for distinguishing between decoding a still
    image or an image sequence for a container format that has both (e.g. HEIF).
    https://review.skia.org/232839

  * SkImage::makeTextureImage and SkImage::MakeCrossContextFromPixmap no longer
    take an SkColorSpace parameter. It was unused.
    https://review.skia.org/234579
    https://review.skia.org/234912

  * SkImage::reinterpretColorSpace - to reinterpret image contents in a new
    color space.
    https://review.skia.org/234328

  * Removed SkImage::MakeCrossContextFromEncoded.
    https://review.skia.org/234912

  * Add Metal support for GrFence, GrSemaphore, and GrBackendSemaphore
    https://review.skia.org/233416

  * SkMallocPixelRef: remove MakeDirect and MakeWithProc from API.
    https://review.skia.org/234660

  * Remove 4-parameter variant of SkRect::join() and intersect(), and
    noemptycheck variants of intersect().
    https://review.skia.org/235832
    https://review.skia.org/237142

  * Remove unused sk_sp comparison operators.
    https://review.skia.org/236942

  * Add SkColor4f variant to experimental_DrawEdgeAAQuad for SkiaRenderer.
    https://review.skia.org/237492

  * Deprecated maxCount resource cache limit for Ganesh.
    This hasn't been relevant for a long time.

  * Changed GrContextOptions' fDisallowGLSLBinaryCaching to fShaderCacheStrategy,
    and allow caching SkSL.
    https://review.skia.org/238856

  * Added kRG_88_SkColorType. This is intended to help support YUV uses case (e.g., NV12).
    As such, the addition is focused on allowing creation of SkPixmaps and SkImages and not
    SkSurfaces (i.e., who wants to render to RG?)

  * Add GrContext::precompileShader to allow up-front compilation of previously-cached shaders.
    https://review.skia.org/239438

  * Added kAlpha_16_SkColorType and kRG_1616_SkColorType. This is intended to help support HDR YUV
    uses case (e.g., P010 and P016). As such, the addition is focused on allowing creation of
    SkPixmaps and SkImages and not SkSurfaces (i.e., who wants to render to render to these?)
