Summary

​This is final release of PrusaSlicer 2.9.0, introducing multiple beds, scarf seams, Printables integration, improved support for multiple nozzle diameters, paint-on fuzzy skin and many more improvements and bugfixes. The final release fixes three bugs found in 2.9.0-rc1. See the release logs of 2.9.0-rc1, 2.9.0-beta1 and 2.9.0-alpha1 for the complete list of changes with respect to 2.8.1.

Important note for Linux users: As noted before, we are now using Flathub as the only official distribution channel of PrusaSlicer on Linux. The reasons behind this decision and what it means for you are described at the end of 2.9.0-alpha1 release log.

Bugs fixed with respect to 2.9.0-rc1

• Fixed a crash in a specific case when slicing multimaterial-painted objects (prusa3d#13676, prusa3d#13798).
• Fixed a crash when slicing multimaterial-painted objects on a printer with less extruders than painted.
• Fixed highlighting of the active bed in case that the bed has a big custom model which would overlap neighboring beds (mentioned in prusa3d#13791).

Summary

​This is final release of PrusaSlicer 2.8.1, fixing one bug found in 2.8.1-rc1. Read the change log of 2.8.1-rc1 for complete list of improvements and bugfixes with respect to 2.8.0

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 (prusa3d#13384).
• A warning about inconsistent color profiles in PNGs used as Prusa Account avatar is now silently ignored (prusa3d#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.

Build	min libwebkit2gtk version	distributions examples
older-distros	4.0	Ubuntu 22.04, Fedora 39, Debian 11
newer-distros	4.1	Ubuntu 24.04, Fedora 40, Debian 12

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.

Test builds for goo-format-support-dev branch

These are builds from the goo-format-support-dev branch which aims to add support for the Elegoo open-source .goo format. This format is currently used by Elegoo Mars 4 series printers.

The branch is currently in a development state and the pull request to the main PrusaSlicer repo is still open and in draft mode. Releases of this branch are therefore primarily meant for testing out the new features before merging into PrusaSlicer.

Note: These builds are generated automaticly by github actions and added to this release marked with a date. If you want to build PursaSlicer with the added features for yourself please clone the goo-format-support-dev-ci-build branch and use the provided linux_build.sh or windows_build.bat scripts depending on your target platform. Downloading the source-code archives directly from this release might not get you the latest code. Please also read the Development notes for your platform in the main README of PrusaSlicer to ensure required software and dependencies are installed before building.
