I have put a potential Release Candidate for the 3.0 release of calibre2opds for download from
http://code.google.com/p/calibre2opds/downloads/. If no show-stoppers are identified then after some final tidying of documentation this will be promoted to be the general release and we will start working on the 3.1 release.
The intention is to provide a significantly more rapid turn around on future releases so there should not be as long a wait for the next release.
With this release I have attempted to again provide a dmg package build for Mac users. However as I do not have a Mac of my own I built this using the TransMac tool on Windows and then tested it on my notebook running Leopard (the latest OSX version I can use) in "Hackintosh" mode. I would like confirmation that it works OK on later OSX versions such as Snow Leopard or Lion.
