This contains a fix for another security vulnerability related to zip file imports, so please don't import any zip files you don't trust unless you're on the latest version.

This version of PolyMC comes with a fix for a security vulnerability in the "import from zip" create instance option.
If for any reason you haven't updated to version 5.0 or above do not use the "import from zip" option unless you are 100% sure that the file you're importing is safe (meaning you analysed it yourself and determined that it's safe, or you're the one who authored the file).
Please ensure in 'Help > About PolyMC' that you are running on at least version 5.0 before trying to use the "import from zip" option on any untrusted files.
As of this release being created, Flathub still hasn't updated to 5.0, so seriously do make sure that you're on 5.0 before using the "import from zip" option. Flatpak users will likely have to wait up to a few hours for the PolyMC Flatpak to be updated on Flathub.

Due to most of our packaging getting pulled as a result of a misinformation campaign and fake malware scares, the methods for installing PolyMC have changed. Our packages on Scoop, Chocolatey, WinGet, PortableApps, Flathub, COPR, NixPkgs, Gentoo, and more have been either removed or otherwise affected, so PolyMC can no longer be reliably installed in these ways.
Visit https://polymc.org/download for the latest information on how to install PolyMC.
The recommended way of using PolyMC on Linux is now by using the AppImage, Flatpak, or compiling from source, since most distro repositories have removed PolyMC. If your distro still packages an up-to-date distribution of PolyMC then feel free to keep using it.
For Steam Deck, we recommend using the Flatpak. The installation method is described below or at https://polymc.org/download/linux#flatpak, since PolyMC no longer appears in the Discover store for the time being.
If you need any help with installing PolyMC or with anything else PolyMC-related then as always you can get support on our Matrix room, our Discord server, or our Subreddit. These are linked in the project's README
PolyMC is back on Flathub, so we recommend installing it directly from there.
flatpak uninstall org.polymc.PolyMC
in a terminal which will uninstall PolyMC but it won't delete any of your instances or saves etc. You may need to do this first before installing it from Flathub.flatpak install org.polymc.PolyMC
