This is the first Release Candidate for Geeklog 1.3.10 (NOT the finished product yet). You are encouraged to try it out, but for the time being, Geeklog 1.3.9sr2 may be the safer option ...
Geeklog 1.3.9 is a recommended upgrade for all Geeklog users, introducing many new features, but also includes bugfixes and a stricter parameter checking. This is a complete tarball, to be used for fresh installs.
This is the third Release Candidate for Geeklog 1.3.9. This is still NOT the final release yet - so for new installs, you should be downloading 1.3.8-1sr4 instead.
