It has been decided that we have finished adding features to the Calibre2opds 3.3 release, so the latest build (currently rev 269) has been designated as a Release Candidate. If no issues are reported in the next week or so that require fixing then this will become the final 3.3 release and we will start working on the 3.4 release for any new features. There are lots of new features present in the 3.3 release based on feedback from users. Many users do not like using releases designate as beta so getting the 3.3 release into ‘final’ state will help encourage users to move on from the 3.2 release (this is important as many bugs reported against the 3.2 release are fixed in the 3.3 release)..
There was one significant feature that we had originally envisaged might make the 3.3 release that proved hard to implement and therefore are now going to be delayed until at least the 3.4 release. This was the ability to specify Calibre custom columns that could be used to generate a new Catalog sub-section that would behave rather like the current Tags section. Associated with this was the enhancement to the calibre2opds search syntax to support custom columns.
A point to note is the move to using GoogleDrive to host downloads. This is not nearly as friendly as the previous downloads based on GoogleCode, but has been forced on us as Google discontinued the ability (from mid-January) to add new downloads to GoogleCode. If any users have suggestions on improving the GoogleDrive experience for downloads then we would welcome them.
