We'll be typesetting some Bangla (Bengali script) text in June, which afaik is before the TeXLive 2014 comes out. 1) Do you happen to know whether the 2013 version's bugs break Bangla? The bugs I’m aware of aren’t related to Bengali, but the number of bugs is small anyway so not many texts/fonts are affected. I suppose that's an unanswerable question, since it probably depends on the exact font we'll be using, and maybe the 2013 version hasn't been tested with Bangla anyway. So: AFAIK, HarfBuzz has been regularly tested for Bengali. 2) I assume this: http://www.freedesktop.org/wiki/Software/HarfBuzz/ is where I should go for the latest HarfBuzz (at the moment, the 30 Jan 2014 release), Yes. correct? And that I don't need to install any revised version of anything else from TeXLive 2013. Things are a bit more complex. TeX Live binaries from TUG are statically linked so that all dependencies are included in the binary, installing a new HarfBuzz in this case has no effect on XeTeX as it will keep using the one compiled into it. On the other hand, distributions that package TeX Live will almost always dynamically link, so that XeTeX will be using the system installed HarfBuzz and here updating HarfBuzz will affect XeTeX as well. But if you can build HarfBuzz from source, you probably can rebuild XeTeX too, it is a little harder but we can discuss it when the need actually arises.

Thank you. These are the fonts coming with texlive-2013.
Can you try to compile this sample and look at ligature tr (gotra) on
first line, ligature śr on second line and ligature pr on third line.

Yes, byt TL 2013 contains the official release of FreeFont dated
2012-05-03. This release does not work with Harfbuzz. A lot of
problems were fixed, the working version appeared on subversion about
half year ago. Thus even a bit old revision works but definitely not
the official release.

Attached, all OK with a newer version of FreeFont.
