Comment (by sambthompson):

 {{{
 $ port livecheck mkvtoolnix
 mkvtoolnix seems to have been updated (port version: 23.0.0, new version:
 29.0.0)
 }}}

 There was a fix in 28.2.0 for a use-after-free security risk (Cisco TALOS
 2018-0694), also useful improvements in 25.0.0 for other language
 interface support.

 Thanks!
