I've just released AsciiDoc version 8.6.6.
The most significant changes are to the AsciiDoc plugin architecture,
it has been enhanced, unified and extended -- you can now manage
backend, theme and filter plugins.
There are also dozens of smaller additions and quite a few bug fixes.
Read the CHANGELOG (http://www.methods.co.nz/asciidoc/CHANGELOG.html)
for a full list of all additions, changes and bug fixes.
The website layout has changed to pure CSS and the 'Filters' page has been
renamed to 'Plugins'.
Thanks to all who contributed to this release.
No you didn't miss anything, the themes are in the tarball but seem to
be missing from the zip archive.
