+Milestone 79
+------------
+
+  * SkTextBlob::Iter to discover the glyph indices and typefaces in each run
+    https://review.skia.org/246296
+
+  * Added support for PQ and HLG transfer functions to SkColorSpace.
+    https://review.skia.org/249000
+
+  * Added new api on GrContext ComputeImageSize. This replaces the hold static helper
+    ComputeTextureSize.
+    https://review.skia.org/247337
+
+  * New versions of SkSurface async-rescale-and read APIs that allow client to extend
+    the lifetime of the result data. Old versions are deprecated.
+    https://review.skia.org/245457
+
+  * Add SkColorInfo. It's dimensionless SkImageInfo.
+    https://review.skia.org/245261
+
+  * Added SkPixmap-based createBackendTexture method to GrContext. This allows clients to create
+    backend resources (initialized with texture data) that Skia/Ganesh doesn't know about/track.
+    https://review.skia.org/244676
+
+  * Add explicit src and dst colorspace parameters to SkColorFilter::filterColor4f()
+    https://review.skia.org/244882
+
+  * Remove Vulkan/Metal float32 RGBA texture support
+    https://review.skia.org/244881
+
+  * Add SkSurface::MakeFromCAMetalLayer
+    https://review.skia.org/242563
+
+  * Added kAlpha_F16_SkColorType, kRG_F16_SkColorType and kRGBA_16161616_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?)
+    https://review.skia.org/241357
+
+  * Start to move nested SkPath types (e.g. Direction, Verb) up to root level in SkPathTypes.h
+    https://review.skia.org/241079
+
+  * Remove isRectContour and ksNestedFillRects from public
+    https://review.skia.org/241078
+
+  * 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?)
+    https://review.skia.org/239930
+    https://review.skia.org/235797
+
+  * Make the size of program/pipeline caches configurable via
+    GrContextOptions::fRuntimeProgramCacheSize
+    https://review.skia.org/239756
+
+  * 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?)
+    https://review.skia.org/239930

   * 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
