File Name

modsync-0.4.0.jar

Supported Versions

  • Early Access

[0.4.0] - 2026-01-22

Added

  • Self-upgrade command: /modsync selfupgrade [check|apply] to check for and install ModSync updates directly from GitHub Releases
  • Version display: Plugin version is now shown in logs on startup and via /modsync status
  • Config options: New settings checkForPluginUpdates and includePrereleases for self-upgrade behavior

Changed

  • Atomic mod installation: Mods are now validated (manifest, hash) before being moved to their final location - no more orphan files if validation fails
  • Resilient downloads: Both mod downloads and self-upgrades now use retry logic (3 attempts with exponential backoff) and fallback file operations

Fixed

  • Orphan mod files: Fixed issue where downloaded mods could remain in the mods folder without being tracked if manifest reading failed
  • File move crashes: Download operations now gracefully handle locked files and filesystem errors

tl;dr

ModSync can now update itself! Use /modsync selfupgrade check to see if a new version is available, and /modsync selfupgrade apply to install it. Downloads are now more reliable with automatic retries and proper cleanup on failure.
