Sorting of opaque objects now respects camera settings (opaqueSortMode) and disables front-to-back sorting when a GPU has HSR and camera is set to OpaqueSortMode.Default.

com.unity.render-pipelines.lightweight/CHANGELOG.md

 The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
 and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).
 
+## [3.5.0-preview]
+### Added
+- Sorting of opaque objects now respects camera opaqueSortMode setting.
+- Sorting of opaque objects disables front-to-back sorting flag when camera settings allow that and the GPU has hidden surface removal.
+
 ## [3.4.0-preview]
 ### Added
 - When you have enabled Gizmos, they now appear correctly in the Game view.
