### Desktop

#### Bug Fixes

- Fix multiple open tabs causing document writes to not persist, leading to data loss after an app restart.

### Mobile

#### Bug Fixes

- Fix multiple open tabs causing document writes to not persist, leading to data loss after an app restart.

### Security Notice (Windows)

This Windows release is signed with a newly renewed code-signing certificate. Because Windows SmartScreen builds reputation per certificate, you may temporarily see an "unrecognized app" warning. This build is properly signed and safe — if prompted, select **More info → Run anyway**. The warning will clear as the certificate establishes reputation.
