## Feature Updates
- Composer suggestion menus now support Tab to accept the highlighted Skill or Slash Command, with clear keyboard guidance and no impact on standard focus navigation or mobile selection.
- When one prompt generates multiple apps, each app now shows its own progress and remains visible in the chat.
- Presented files are now isolated by chat and support batch downloads.

## Bug Fixes & Improvements
- Large computed cells no longer block unrelated formula, lookup, and rollup updates. Compute Activity also retains field-level size errors until the next successful refresh.
- Record creation near table limits now preserves valid writes when safe while continuing to reject operations that cannot be completed safely.
- Fixed table schema updates that could fail when computed backfill values involved date-time fields.
- Improved response times for single-record inserts, upserts, and lookup or formula cascades, particularly in high fan-out tables.
- Strengthened scoped personal access token enforcement so permissions cannot exceed configured action and resource scopes. Integrations relying on previously over-permissive access may now receive `403` responses.
- GitHub sync now shows an accurate in-progress status, removes temporary branches after conflict recovery, and uses clearer messages for initial baseline commits.
- Improved computed-field reliability during high-volume updates and when processing outdated dependencies, preventing avoidable failures and repeated retries.
- Improved search indexing controls so private and functional pages, including login, settings, developer, and base pages, are less likely to appear in search results.
- Fixed question cards so the highlighted option always matches the submitted selection.
- Improved attachment caching so public images and private previews load more consistently, while reducing stale avatars after profile updates or user deletion.
- Failed CSV imports now report the original failure accurately instead of remaining pending or later showing an unrelated repair error.
- Fixed an issue that could prevent tables from opening and restored table statistics and aggregations on the current query path.
- AI text and image automations now return more appropriate `400`, `422`, `429`, or `504` responses for input, capability, attachment, response, rate-limit, and timeout errors instead of misleading server errors.
- Required linked records are now validated when writing, preventing dependent links from being cleared or deleted unexpectedly. Linked-record title refreshes also preserve required display values.
- Fixed record duplication failures in tables with linked or lookup fields involving date-time comparisons.
