### Changed

 * Real-Time Collaboration: Avoids showing a newer-autosave warning when the autosaved
   content is already confirmed in the shared document, while retaining the warning
   when content may be missing because a user edited alone or the collaboration 
   backend was unavailable. See WordPress/gutenberg#80539.
 * Real-Time Collaboration: Compacts the CRDT snapshot when serializing it for persistence,
   preventing deleted editing history from continually inflating post meta without
   removing the live session’s undo history. See WordPress/gutenberg#80707.
 * Real-Time Collaboration: Retains the inner-template synchronization fix from 
   WordPress/gutenberg#79021. The VIP RTC plugin version is unchanged at `v0.3.2`.
 * Updated the wp-parsely submodule (used for local development environments) to
   version 3.23.5.
 * Real-Time Collaboration: Created block templates synchronously during insertion
   so connected peers received a single complete block without duplicate template
   contents.

### Fixed

 * Real-Time Collaboration: Prevents derived updates from controlled blocks such
   as Navigation from intercepting a collaborator’s first undo or clearing redo.
   See WordPress/gutenberg#80503.
 * Post Preview: When RTC is disabled, uses WordPress Core’s autosave handling so
   reverting a title to its published value does not leave Preview showing stale
   autosave content. See WordPress/gutenberg#80769.
 * Real-Time Collaboration: Displayed collaborator selections that spanned mixed
   text and non-text blocks, whole-block keyboard selections, and entire posts.
 * Real-Time Collaboration: Cleared the post’s dirty state after successfully saving
   edited post metadata.
 * Real-Time Collaboration: Wrapped long usernames and mentions in the notes sidebar
   so the text remained readable.

### Added

 * RTC: Added configuration support for the multiplexed WebSocket transport.
