This is an autobuild release of PrusaSlicer.
There are no guarantees that this build is stable, no additional testing has been done.
The PrusaSlicer builds attached below include the following extras:
- Option to add svn revision postfix on g-code export (from branch svn-integration)
- Tool for embossing svn revision (shortcut V) (from branch svn-integration)
Please note that any revision-emboss text will not be stored in the .3mf project file.
Revision information always consists of two parts:
- revision of construction source file (prefix s)
- revision of the .3mf project file (prefix p)
The respective revisions will be marked with * or mod in case either the construction source or the project file have been modified since the last commit.
If the file opened in PrusaSlicer is not yet saved or fully committed, PrusaSlicer will show a prompt option to automatically save and commit the file.
Please note that the attached source archives do not contain the source code of the extras as they are kept separately on the feature branches listed above.
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 (#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.
| 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.
