What's new in CubicWeb 3.18?

============================

New functionalities

--------------------

* add a security debugging tool

  (see `#2920304 <http://www.cubicweb.org/2920304>`_)

* the primary view display controller (uicfg) now has a

  `set_fields_order` method similar to the one available for forms

API changes

-----------

* not really an API change, but the entity permission checks are now

  systematically deferred to an operation, instead of a) trying in a

  hook and b) if it failed, retrying later in an operation

* The default value storage for attributes is no longer String, but

  Bytes.  This opens the road to storing arbitrary python objects, e.g.

  numpy arrays, and fixes a bug where default values whose truth value

  was False were not properly migrated.

* `symmetric` relations are no more handled by an rql rewrite but are

  now handled with hooks (from the `activeintegrity` category); this

  may have some consequences for applications that do low-level database

  manipulations or at times disable (some) hooks.

Deprecation

---------------------

* ``pyrorql`` sources have been deprecated. Multisource will be fully dropped

  in the next version. If you are still using pyrorql, switch to ``datafeed``

  **NOW**!

* the old multi-source system

Deprecated Code Drops

----------------------

* ``ldapuser`` have been dropped; use ``ldapfeed`` now

  (see `#2936496 <http://www.cubicweb.org/2936496>`_)

* action ``GotRhythm`` was removed, make sure you do not

  import it in your cubes (even to unregister it)

  (see `#3093362 <http://www.cubicweb.org/3093362>`_)

* all 3.8 backward compat is gone

* all 3.9 backward compat (including the javascript side) is gone
