+### Changes
+- Fixed sprite character and sprite glyph scale not being reflected in the text layout. See [forum post](https://forum.unity.com/threads/glyph-scale-dont-change-line-height.898817/) for details.
+- Fixed potential null reference exception in the CrossFadeColor or CrossFadeAlpha functions. See [forum post](https://forum.unity.com/threads/version-1-5-0-2-1-0-3-0-0-preview-13-now-available-for-testing.753587/page-4#post-5885075) for details.
+- Minor improvements to the Sprite Asset Importer to improve allocations and address potential error encountered when creating multiple sprite assets. 
+- TMP GUID Remapping Tool - Removed "UnityEditor.Animations.AnimatorController" from the exclusion search list.
+- Fixed potential culling issue when dynamically updating the content of child text objects of RectMask2D components. Case #1253625
