New hotfix release v4.20.2

Update handling of the '@' character in signatures names

2025-07-08

🔗Update handling of the '@' character in signatures names

Microsoft no longer allows '@' in roaming signature names as it is reserved for internal use, and Microsoft Outlook will follow soon.

This hotfix addresses this change as follws:

  • Add '@' to the list of invalid characters for signatures names as documented in sample INI files. The new complete list of invalid characters is '\/:"*?><, @'.
  • Convert all invalid characters to '', but '@' to '_at'.
  • Only keep the '@' character where it is required for Microsoft internal use in roaming signature names.

For a comprehensive list of all changes, dependencies, and fixes, please consult the official CHANGELOG.
