From the announcement:

I am very proud and very very happy to announce the release of Syllable
0.6.6 at long last!

This has been the longest, most difficult release we have ever overseen,
and I'd like to say a huge, massive thank you to Kaj and Anthony for
their help and support, to every single person who has contributed to
making this release happen, and of course to everyone in the community
to continuing to support Syllable even when things have been very quiet.
