Summary

This is the second release candidate of PrusaSlicer 2.8.0. This release candidate fixes several bugs found in previous 2.8.0-rc1.

The release candidate saves its profiles into regular PrusaSlicer configuration directory. When you first run it, it will search for all configurations produced by alpha or beta versions and offer to create a copy of the latest one.

AppImage for Ubuntu 24.04

An AppImage running on Ubuntu 24.04 is finally provided (unlike previous releases). The problem was that PrusaSlicer now depends on WebKit library, which is a big library with many dependencies. The new Ubuntu 24.04 uses new version of WebKit which is incompatible with our binaries. Bundling WebKit into the AppImage has proved to be difficult, because it has many dependencies and bundling them too leads to many other issues.

Therefore, instead of bundling all the libraries into a single huge AppImage, we provide two separate AppImages. One depends on the old WebKit (which is currently shipped with almost all relevant Linux distributions), the other one is built on Ubuntu 24.04 and links to the new WebKit.

To keep the confusion to a minumum, we do not provide the tarballs anymore, just the two AppImages. They are able to extract themselves when run with --appimage-extract command line parameter.
