ProjT Launcher Update 0.0.1, now available

Published on November 16, 2025 • ProjT Launcher

We are excited to announce the first official release of ProjT Launcher: version 0.0.1!

This marks a major milestone for the project, as it represents the beginning of our fully independent development path after moving away from our Prism Launcher origin.

Important Notice:
Microsoft/Mojang authentication is not yet functional in this release.
The API approval process is still in progress, and required application signatures (code-signing certificates & macOS notarization) have not been issued yet.
Once API approval and signing certificates are finalized, MSA login will become fully available in a future update.

  • Fully detached repository identity from Prism Launcher upstream.

Fixed

  • Fixed zlib module path resolution in the build system.

  • Fixed launcher startup issue where Platform: unknown was displayed.
  • Fixed GitHub Actions cache misconfigurations leading to failed builds.
