PolyMC version history

8.0 Sep 30, 2026

This release contains some juicy new features, alongside UI enhancements, bug fixes for modpack providers and legacy versions, and most importantly:the ability to play on blacklisted servers, such as 6b6t!

Features

  • Servers that are otherwise blacklisted by Microsoft can now be played on, such as 6b6t. @crueter in https://github.com/PolyMC/PolyMC/pull/1794
  • You can now download resource, texture, and shader packs from Modrinth or Curseforge. This works in beta versions too! @crueter in https://github.com/PolyMC/PolyMC/pull/1804
  • The instance server list has been improved, now showing important data (player count, icons, etc.). @Kaydax in https://github.com/PolyMC/PolyMC/pull/1730
  • Old versions of Minecraft with Forge installed previously did not work with modern Java 8 runtimes. The new "Ignore Forge security errors" option allows modern Java runtimes to bypass this and play old versions of Minecraft with Forge. @crueter in https://github.com/PolyMC/PolyMC/pull/1795
  • You can now use the Loki Yggdrasil agent as a custom authentication alternative for versions 0.0.18a to 1.6.4. @thedirtybubble in https://github.com/PolyMC/PolyMC/pull/1790
  • You can now use locally hosted HTTP metadata servers. @JackOfNoneTrades in https://github.com/PolyMC/PolyMC/pull/1762
  • Windows on ARM now has a setup executable (Windows 11 only). @crueter in https://github.com/PolyMC/PolyMC/pull/1797
  • Linux AppImages can now automatically update themselves if a new upstream version is present. …

Apparently there's NeoForge support in this one or something idk I don't play Minecraft.
Notice
If you use AppImageLauncher then it will not work with the PolyMC AppImage unless you're using the v3.0 alpha of AppImageLauncher.
