Release 1.3.0 introduced a commenting system and was a pretty big change overall. Aside from the comment system it also introduced the possibility to have multiple instances of Swiftfire running in parallel. This is very convenient if you run Swiftfire on a development machine.
Our website at http://swiftfire.nl is still being updated to detail this release.
Since then 1.3.1 and 1.3.2 have removed a few bugs that had crept in up to release 1.3.2.
Now 1.3.3 has been released which also completes the addition of the Linux platform for development and deployment. However we ourselves do not use the Linux platform for development (or deployment) thus we depend on you to report any issue's that you might have.
