The second Release Candidate for Geeklog 1.3.10 is now available for download. It fixes are variety of (mostly minor) bugs in rc1 and also addresses the email problems some users were having (the complete list of changes since rc1 can be found in docs/history).
Please give it a try, but keep in mind that it's still not the final version yet. To upgrade from 1.3.10rc1, please see the enclosed list of changed files in docs/changed-files. There were no database changes, so you only have to replace the files that have changed.
We'll give this Release Candidate a bit more time now so as to find the remaining problems and also give the translators a chance to catch up.
