After more then a year of silence, I released a minor MW 1.16 compatibility
fix for HeaderTabs (v0.6.6).
I also moved repository to Wikimedia repository so this release is available
and latest development code is here:
If you're using Sunversion, you'll have to remove the old version and
checkout from new repository again
Hope this version solves the issue for MW 1.16 and up, let me know if it
works for you.
CCing SMW dev and user lists as it seems to be popular there (thanks to
Yaron promoting it with SF ;)).
P.S. I still hope to spend some time upgrading to latest version of YUI as
well, but another time.
