Summary

This is the first release candidate of PrusaSlicer 2.8.0. This release candidate fixes bugs found in previous 2.8.0-beta1.

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.

An important note for Linux users: The provided binaries will not run on newest Ubuntu 24.04 (and possibly other latest distributions). Solving problems with all dependencies is more work than originally expected. We hope to get it sorted for the 2.8.0 final release.

Improvements with respect to 2.7.5-rc1

• SLA specific: Added correction for cross layer curing. When printing using the MSLA technology, the UV light cures not only the layer it is "supposed" to, but it also reaches couple of already printed layers. This leads to deformations of the print, especially at overhangs. There is a now new parameter in Material Settings. It states how many layers are be affected by the cross layer curing for the particular Material, and PrusaSlicer is able to compensate for this effect by "deforming" the slices in the opposite way.

Bug fixes with respect to 2.8.0-beta1

• macOS specific: Fixed performance issues when run as standalone G-code Viewer.
• Toolbar size set in Preferences was not taken into account (https://github.com/prusa3d/PrusaSlicer/issues/12838#issuecomment-2176534793).
• Fixed crash when selecting Color Print view in Preview (#12881).
• Fixed behavior of vertical slider: Color Change was added after moving slider when it was moved to its original position (#12877).
• macOS specific: Some keyboard shortcut did not work (#12874).
• Linux specific: The application stays logged in to Prusa Account when it is restarted.
• Loading of SLA archives did not work when path to the archive contained non-ASCII characters (this was actually already fixed in 2.8.0-alpha5).
