v4.5.1

Release Date: 22 August 2026

Version 4.5.1 is a maintenance and safety release. It protects your settings, PRO licence and prompt profiles against data loss during updates and reinstalls, fixes a settings-reset bug, and makes the PRO licence resilient to temporary network problems.

🛡️ What's New in Version 4.5.1

Your data is now protected

  • Settings can no longer be silently reset. Fixed a bug where a settings file saved in Windows Notepad (UTF-8 BOM) - or containing a % character in any value - caused all settings to be reset to defaults on the first launch after an update. The original file is now preserved as .bak / .corrupted.bak before any rewrite.
  • PRO licence recognition fixed. The machine-ID check now accepts any valid local hardware identifier, so a temporarily unavailable detection method no longer triggers a false "licence is for a different computer" error.
  • PRO works offline for up to 7 days (Grace Period). If online verification fails because of a connection problem (e.g. no internet, or a firewall blocking the freshly updated app), your PRO licence stays active for 7 days since the last successful online verification.
  • Automatic disaster-recovery backups. Your settings, licence and prompt profiles are now backed up to %APPDATA%\GameChangingTranslator\backups\ on application exit and before every update — with a dedicated MASTER anchor vault protecting your licence and API keys against any accidental loss or reset.
  • New "Restore Settings/Licence from Backup" button in the About tab. One click restores your settings, PRO licence and prompt profiles from the backup store (with automatic licence and API key fusion from MASTER) and restarts the app cleanly.
  • Safer updates. Downloaded installers are size-verified (truncated downloads are rejected), failed updates roll back completely (including the launcher), custom prompt profiles (.ctp/.cop) are explicitly preserved, and the updater no longer risks terminating unrelated processes.

Note: Updating from 4.5.0 or earlier to 4.5.1 already preserves all user files. The enhanced rollback protection takes effect for updates starting from version 4.5.1.
