+            <description>
+                <p>PrusaSlicer 2.3.3 is a patch release following PrusaSlicer 2.3.2 release, fixing an unfortunate bug in handling FDM multi-material 
+                project and configuration files #6711.</p>

+        <release version="2.3.2" date="2021-07-08">
+            <description>
+                <p>This is a final release of PrusaSlicer 2.3.2, following 2.3.2-beta and 2.3.2-rc. 
+                For the new features in the 2.3.2 series, please read the change logs of the beta and release candidate. 
+                The final release is functionally equal to the release candidate, with a single additional improvement:
+                Before installing profile updates, a configuration snapshot is taken. In rare circumstances when the current configuration is not consistent, 
+                taking a configuration snapshot fails. PrusaSlicer 2.3.2 newly informs about the issue and offers either to install the configuration updates 
+                even if taking the configuration snapshot failed or to abort update of the profiles.</p>
