The 5.0.3 will take more time than the 5.0.2 and 5.0.1 releases. I expect it to take close to a month or so.
I do not expect to have a 5.0.4 but then that is the plan as of now.
The 5.0.3 will focus mostly on the email issue. There will be some usability and ui updates as well. There will not be any new features, just fixes.
We have fixed the Release Notes issue too this time and will be automating the process so that it does not happen again.
There have been suggestions on the usage of the svn. I am having a look at it right now and hope to get back on that soon.
