I think it is tied to this ticket:
https://code.mythtv.org/trac/ticket/9294
It looks like the changes went into 0.25, although they depend on 
whether an external library of the appropriate version was installed 
when the mythtv binaries were built.

What version did you upgrade from?

I can tell you that when I play matroska files with muxed in srt 
subtitles in 0.27, that external library IS rendering the subtitles. But 
I've also got some matroska files with external srt files. When I play 
those, mythtv code is doing the rendering. In this case, both 
osd_subtitle.xml and subtitle zooming work as expected. I'm 90% sure if 
you extract the muxed in subtitles into an external .srt file, your 
osd_subtitle.xml file will be used and subtitle zooming will work.
