## Feature Updates
- Using a solution from a template preview now creates a new copy and opens the setup page, consistent with the Template Center. The setup page no longer offers a “Later” option.

## Bug Fixes & Improvements
- Fixed an issue where the grid in a template preview might fail to load records, and improved the reliability of creating from a template.
- When starting a chat, App Builder now opens in preview mode; the environment clipboard label is also clearer.
- Fixed an issue that prevented saving a shared Base when a linked table or field was missing.
- Date fields now sort by the full timestamp, even when the display format hides the time. Date grouping still follows the display format.
- Bulk collaborator assignments now generate fewer duplicate emails. Emails covering multiple records use clearer wording, summarize the records, and include a link back to the table.
- When deleting an account, both desktop and mobile now show the spaces the user owns and the actions required. Fixed an issue where typing cleared the desktop confirmation field, and another where the mobile “Delete Account” link opened a nonexistent page.
- In shared chats, unread indicators and reply notifications now follow the person who most recently asked a question, preventing unread indicators that other viewers cannot clear.
- Improved response times for Bases containing complex linked records and Lookup calculations.
- Rotating a Secret now preserves existing credential bindings; newly granted access requires approval.
- Improved the security of email verification code sign-in: a fresh verification check now runs before a code is sent or resent. When Turnstile is enabled, integrations that send these codes must provide a Turnstile token.
- Improved the reliability and speed of publishing apps from projects with many bound Secrets.
- Formula changes are now validated before saving. Edits that fail validation remain as drafts, while previously working definitions and values remain unchanged; calculation failures also no longer partially overwrite existing values.
- Fixed an issue where Record History showed a blank panel when certain Formula, Rollup, and Conditional Rollup fields changed.
- Audit logs now distinguish user-created personal access tokens from automatic token refreshes, reducing misleading entries.
