-### 5.9.0 and later
+### 9.4.2, 9.5.0: stuck on muxing MPLS/Blu-rays
 
-mkvmerge writes new Matroska elements by default which a lot of players have problems with. See [Playback does not work VLC cannot seek mkvmerge v5.9.0](Playback-does-not-work-VLC-cannot-seek-mkvmerge-v5.9.0) for the full explanation and workarounds.
+Muxing MPLS files from Blu-rays can cause mkvmerge to get stuck in an endless loop. The [issue has already been fixed](), and new [pre-builds for Windows](https://mkvtoolnix.download/windows/pre/) are available.
+
+### Current versions: Error message "JSON output could not be parsed"
+
+It seems that certain anti virus tools prevent mkvmerge from getting executed properly. See [this FAQ entry](JSON-output-could-not-be-parsed) for more information.
