I am pleased to announce the release of CubicWeb 3.23. Many thanks to
contributors of this release which, according to Mercurial, are:
Alexandre Richardson, Arthur Lutz, Aurelien Campeas, David Douard, Denis
Laxalde, Florent Cayré, Julien Cristau, Laura Médioni, Nicolas Chauvat,
Philippe Pepiot, Rémi Cardona, Samuel Trégouët, Sylvain Thénault and
Vladimir Popescu.

This release comes along with Yams 0.45 and logilab-common 1.2.2.

Main changes in this release are listed below and are also available at

New features

-   Python 3.x support in CubicWeb itself is now complete, except for
      the twisted package (since Twisted does not completely support
      Python 3.x itself). The skeleton for new cube should also be Python
      3 compatible, in particular its setup.py got updated.
-   The source-sync command can now synchronize all sources in the
      database, if no <source> argument is provided.
-   Datafeed source synchronization is now asynchronous when requested
      from user interface.

Database handling

-   Most indexes and constraints will be rebuilt during the migration,
      because they are now named after a md5 hash to control the name's
-   Index are renamed upon renaming of an entity type, so they are still
      correctly tracked.
-   A new db-check-index command is added to cubicweb-ctl, to display
      the differences between the indexes in the database and those
      expected by the schema. It's recommended to run this command after
      the migration to 3.23 and to adjust things manually for cases that
      are not easily handled by the migration script, such as indexes of
      entity types that have been renamed. It should be mostly about
      dropping extra indexes.


-   Deprecated MetaGenerator in favor of slightly adapted API in
      MetadataGenerator (more consistent, giving more control to
      sub-classes and suitable for usage with the MassiveObjectStore)
-   Major cleanups of the MassiveObjectStore and its PGHelper companion
      -   dropped a bunch of unnecessary / unused attributes
      -   refactored / renamed internal methods
      -   added support for a metadata generator, the now recommended way
          to control metadata generation
-   Deprecated SQLGenObjectStore, MassiveObjectStore should be used

Backwards-incompatible changes

-   Generative tests à la logilab-common are not supported anymore in
      CubicWebTC. It is advised to use the subtests API (available on
      CubicWebTC either from the standard library as of Python 3.4 or
      through unittest2 package otherwise).
-   CubicWebTC's set_description method (comming from
      logilab.common.testlib.TestCase) is no longer available.
