Bugs fixed with respect to 2.8.1-rc1

• When using the wipe tower with "No sparse layers" option enabled, there would still be travels to the wipe tower location even for the skipped layers. This is a regression introduced in 2.8.1-rc1 (#13384).
• A warning about inconsistent color profiles in PNGs used as Prusa Account avatar is now silently ignored (#12920).

IMPORTANT note for Linux users

PrusaSlicer now depends on WebKit library, which greatly complicates its distribution. Latest Linux distributions (such as Ubuntu 24.04, Fedora 40) ship with newer version of WebKit than older (but still supported) distros. Bundling WebKit into the AppImage is difficult and may not be possible.

Therefore, we now provide two separate AppImages, both depending on webkit library. You may need to install the respective package before you are able to run PrusaSlicer.

The AppImages can extract themselves when run with --appimage-extract command line parameter.

It is quite likely that PrusaSlicer will switch only to Flatpak deployment from the next version on. The AppImage made sense when it could be used in the "bundle what you need, distribute a single file" way, but having to distribute several different AppImages and maintaining the required build infrastructure (and still worrying about what needs to be updated when some Linux distribution update is released) means burning time that we would much rather invest into actual work on PrusaSlicer.
