Submission to SlackBuild project is being halted temporary because they are now configuring a new machine that will replace the old machine. I hope the addition of this new hardware can improve this project's performance as more packages are being added into this repository.
Next in my queue line is an update to FileZilla which is now updated to 3.5.3. Please note that this update requires you to upgrade your WxGTK to 2.8.12 or higher in order to compile it from source. I have mentioned it on the README just in case you failed to compile.
Update (9 January 2012): They are back accepting submissions
