No need to upgrade before your performance.  The ones to use are the ones on the release candidate page.

for what's worth: I'm on a sensitive moment now (final stretch to audio-video performance next sunday in salamanca). I can look at this after that, though.

 I think this is basically ready to go

 Please test on Windows and give feedback!  I haven't heard anything about Windows.  It's looking ready for release, so please try it if you haven't already so we can find the last bugs.  As far as I know, there aren't any outstanding bugs that need to be fixed for this release.  So I think this is the release.
 
 Test away and file bugs in the bug tracker!

 This release candidate includes:
 * on GNU/Linux, corrected font size when using Tcl/Tk 8.5
 * moocow/flite speech synth added on all platforms
 * fixed strict-aliasing build problems with cyclone, iemlib, bsaylor, and sigpack
 * (Windows) increased default audio buffer to 100ms since there are some really flaky audio cards in Windows land
 * (Mac OS X) decreased buffers to 20ms since all Apple hardware that I have tested in the past 7 years works with that
