PrusaSlicer

Summary

This is the first release candidate of PrusaSlicer 2.9.0. This release fixes couple of bugs found in 2.9.0-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.

Important note for Linux users: As noted during 2.8.x releases, 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-beta1

  • Windows specific: Export G-code button in the right panel was flickering on mouse move.
  • The Slice Now button did not update after loading an object from the shape gallery (#13777).
  • Fixed undefined behavior when sending G-code to print host. The issue only manifested on macOS with address sanitizer (#13766, #13759, #13750).
  • A tenth bed was offered to the user after loading the project already containing maximum number of beds (a visual glitch, it was not possible to actually use the bed).
  • Fixed empty thumbnail after adding a custom object into the shape gallery (bug introduced in 2.9.0-alpha1).
  • Fixed freeze after a communication with Prusa Account returned a specific error code. This bug was uncovered by a problem on the server side couple of days ago which affected many PrusaSlicer users (#13768, #13762, #13765, #13762, #13745, #13757, #13758, #13748). Extra countermeasures were applied on both sides and they should prevent this from happening again.
  • Fixed incomplete update when switching from FDM mode to SLA: out-of-bed status of volumes and thumbnails in bed selector were not updated correctly.
  • Fixed a crash during slicing introduced between 2.9.0-alpha1 and 2.9.0-beta1.
  • Fixed a crash when switching application language while using the bulk slicing screen.
  • macOS specific: Loading screen displayed when web content is being loaded did not show.

Localization

  • Updated POT.
  • Updated CS, PL, DE, IT, ES, FR, JA dictionaries.
  • Updated RU dictionary (#13438, thanks to @AndylgTom and Dmitry Sorkin).

Note on localization on Linux

When installing PrusaSlicer using Flatpak, only English and the system language are installed by default. In case you want to switch PrusaSlicer to another language, it is necessary to configure Flatpak to use these languages first. For example

will configure Polish and German for Flatpak. It is necessary to reinstall the application after. Running the command with additional --user parameter will only configure the languages for current user, in which case sudo is not required.
