Ging nun doch schneller als erwartet, jedoch habe ich persönlich mit einem größeren Release gerechnet. In der finalen Versionen wurden daher „nur“ Fehler beseitigt, so dass die neuen Funktionen schon in der Alpha, bzw. Beta Version verteilt wurden.


This is a final release of PrusaSlicer 2.4.0, following 2.4.0-alpha12.4.0-alpha22.4.0-alpha32.4.0-beta12.4.0-beta22.4.0-beta32.4.0-beta42.4.0-rc and 2.4.0-rc2. The final release fixes bugs found in the second release candidate. For new features in the 2.4.0 series, please read the release logs of the 2.4.0 alphas and betas.

If you already tested any of the PrusaSlicer 2.4.0 alpha or beta builds, you will be offered to import the recent alpha or beta profiles.
