Here's what I ended up tweeting:

http://twitter.com/Openwall/status/76474625877479424

JtR 1.7.7-jumbo-5: more SSE2/AVX intrinsics, UTF-8, MPI, more #OpenMP,
MS #Kerberos 5 pre-auth, ... http://openwall.com/1775

This left 16 chars free for retweets (such as to fit "Openwall" in those).

BTW, those same SSE2 intrinsics work for 128-bit AVX as well (with the
linux-*-avx targets).  I've just confirmed this for -jumbo-5 specifically.

Technically, yes, but this is bad for retweets.

Indeed.  But besides the technical restrictions, we have to consider
that most people won't read long change lists anyway.
