What's new in calibre2opds 3.0 ?
We had originally started working on a calibre2opds 2.5 release, but as we went on we realized tht the changes we were making were far more extensive than might be expected of a point release. We decided that it was therefore time to jump our version numbering to the 3.x series to reflect this.
The following are the highlights for the calibre2odps 3.0 release. This release is still in beta phase so the exact contents of the final release are subject to change.
Some of the new features are:
 Major Changes
 OPDS 1.1 compatibility
The OPDS v1.1 has now been released, and this version of calibre2opds creates catalogs that conform to this version of the standard.
 Search facilities within HTML catlogs
This facility takes advantages of the facilities in modern browsers with HTML 5 support to do client side searching.
 Featured Books
This feature allows you to specify a set of books from your Calibre library that you wish to give a 'fetured' status to help promote them to your users.

 Minor Changes
There are a lot of small enhancements as well as bug fixes for reported issues. For more detail see the Release Notes that are included with the release.
The following changes and new features are the ones that are most likely to be relevant to the average user:
 Improved Control over Library Images
In the past calibre2opds has generated images that were optimized for use either as covers or as thumbnails for use within the catalog. Those who are space constrained (e.g. DropBox users) ahve asked why the existing Calibre cover.jpg files cannot be re-used for these purposes. The user can now decide on the trade-off they want to make between space or runtime download volume when displaying calibre2opds catalogs.
 Improved User Feedback while Running
calibre2opds has always provided basic feedback at runtime indicating what phase of catalog generation was currently being worked on. However with large libraries some of the phases could take quite a long time to execute. The feedback has now been enhanced to provide more feedback about overall progress. You can now tidily stop a run if for any reason you realise that you do not want to let the catalog generation run to completion.
