What's new in this version:

- MKVToolNix GUI: multiplexer: Windows: using UNC paths (e.g. `serverVideos`) when the option "automatically set the destination file name" was set in the preferences, the GUI would create a destination file name with forward slashes (e.g. `//server/Videos/outputfile.mkv`), a syntax not supported by `mkvmerge`
- build system: the programs were accidentally built without stack protection (`-fstack-protector-strong`) on recent versions of gcc and clang
