In case anyone is tracking the status of the Open Publication
Distribution System (OPDS), v1.0 of the specification was just
released yesterday [1]. OPDS is essentially a pattern for sharing
ebook URLs, and the metadata associated with them, using Atom. Hadrien
Gardeur has a nice list of the changes between v0.9 and v1.0 if you
took a look before, which is included below.
If you are curious, and find examples more useful than specifications,
take a look at the implementations at the Internet Archive [2],
FeedBooks [3], the Pragmatic Programmers [4], or an experimental view
on arXiv [5].

Key changes between 0.9 and 1.0:
Removed references to indirect acquisition, we'll continue discussions
about this outside of the core spec (in an info doc)
The spec is now more generic to open the door to other electronic
content in the future (audio/video, comics etc.)
New rel value for Open Access (http://opds-spec.org/acquisition/open-access)
Modifications for artwork relations
(http://opds-spec.org/specs/opds-catalog-1-0-20100830/#Artwork_Relations)
Modified the definitions and groupes feed-level relations into:
sorting relations, popular relation, previously acquired relations and
crawlable feed relation
"Publications in a format using Digital Rights Management SHOULD use a
different value for the type attribute of the Acquisition Link than
the same format without Digital Rights Management."
More spec language about the relationship between summary/content:
http://opds-spec.org/specs/opds-catalog-1-0-20100830/#Summary_and_Content
Relax NG schema:
http://opds-spec.org/specs/opds-catalog-1-0-20100830/#Appendix_B._RELAX_NG_Compact_Schema
Overall, these are rather minor modifications and shouldn't require
too much work to support them. For a better overlook at changes, you
can also check the Wiki: http://code.google.com/p/openpub/source/list
