Little late but here's a release note for version 6.28:
Provide downloadable template projects
Added file size estimate in export dialog
Preserve track clip fade-ins when using drag-drop-and-replace
Fix possible crash when using effects dialog
Can now change audio stream on the fly for a video with multiple audio streams (Right click in bin -> Select Audio Stream). No longer need to re-import to select a new audio stream.
Version 6.29 is basically the same with a few bug fixes:
Fixed black frame at the end of a fade-in.
Fixed cache bug when resizing overlayed track
Fixed potential crash when splitting a clip with the Censor effect on it
