Version 1.2 of SimpleLog has been released! In addition to the fully functional XML-RPC API (so you can post from desktop apps like MarsEdit or from Flickr), there's also an automatic update checking feature so you'll always know when a new version of SimpleLog is released, without having to manually check (you can also turn this off if you want).
I'm also officially announcing anonymous SVN access and the SimpleLog Trac.
To checkout SimpleLog anonymously, use http://svn.simplelog.net with both the username and password "anonymous" (without the quotes). Obviously, this is the live SVN repository, so keep in mind that there could be bugs in the trunk. I wouldn't recommend using the code in the trunk on your site (unless you like living dangerously), but this will be very useful for people who make changes to the app's main code and want to run things like diff when they go to upgrade.
The Trac is going to become very important from this point on. You can now submit trouble tickets, feature requests and the like, as well as viewing current tickets. You can also get an idea of planned release schedules and browse the source of the app (with SVN notes).
I've still got plenty of features to add to SimpleLog, and development is ongoing. Hopefully, these resources will give you even more of a reason to try SimpleLog, or even switch to it.
Many thanks to Jeremy Bogan of Segpub for helping me get public SVN and Trac set up as well. Segpub is the recommended host for SimpleLog (and I don't get any money from saying that).
Update: Also just released version 1.2.1, a bugfix.
