Nigthly Build

Note

This automatic nighly build is currently not-stable and is very experimental and in active developpement This branch is not stable and changes are made almost daily so this branch can sometimes break. Also, MacOS is not avaiable in the Nigthly Build due to Apple restriction and that I do now own a mac.

In this GitHub Release page you will found Nighly Build which are made automatically via GitHub Action when change are made in the nighly branch

These platform are not tested and may work or not at all

• Other *BSD system, as Minecraft LCE is not supported on those and Wine is not available.
• Minecraft LCE on Android is currently quite laggy and buggy
• macOS: LCE Qt Launcher does not officially support MacOS and is not tested during PRs, but POISX compatibility should allow its use.
