-What's new in CubicWeb 3.20
-===========================
-
-New features
-------------
-
-* virtual relations: a new ComputedRelation class can be used in
-  schema.py; its `rule` attribute is an RQL snippet that defines the new
-  relation.
-
-* computed attributes: an attribute can now be defined with a `formula`
-  argument (also an RQL snippet); it will be read-only, and updated
-  automatically.
-
-  Both of these features are described in `CWEP-002`_, and the updated
-  "Data model" chapter of the CubicWeb book.
-
-* cubicweb-ctl plugins can use the ``cubicweb.utils.admincnx`` function
-  to get a Connection object from an instance name.
-
-* new 'tornado' wsgi backend
-
-* session cookies have the HttpOnly flag, so they're no longer exposed to
-  javascript
-
-* rich text fields can be formatted as markdown
-
-* the edit controller detects concurrent editions, and raises a ValidationError
-  if an entity was modified between form generation and submission
-
-* cubicweb can use a postgresql "schema" (namespace) for its tables
-
-* "cubicweb-ctl configure" can be used to set values of the admin user
-  credentials in the sources configuration file
-
-* in debug mode, setting the _cwtracehtml parameter on a request allows tracing
-  where each bit of output is produced
-
-.. _CWEP-002: http://hg.logilab.org/review/cwep/file/tip/CWEP-002.rst

-
-API Changes
------------
-
-* ``ucsvreader()`` and ``ucsvreader_pb()`` from the ``dataimport`` module have
-  2 new keyword arguments ``delimiter`` and ``quotechar`` to replace the
-  ``separator`` and ``quote`` arguments respectively. This makes the API match
-  that of Python's ``csv.reader()``.  The old arguments are still supported
-  though deprecated.
-
-* the migration environment's ``remove_cube`` function is now called ``drop_cube``.
-
-* cubicweb.old.css is now cubicweb.css.  The previous "new"
-  cubicweb.css, along with its cubicweb.reset.css companion, have been
-  removed.
-
-* the jquery-treeview plugin was updated to its latest version
-
-
-Deprecated Code Drops
-----------------------
-
-* most of 3.10 and 3.11 backward compat is gone; this includes:
-  - CtxComponent.box_action() and CtxComponent.build_link()
-  - cubicweb.devtools.htmlparser.XMLDemotingValidator
-  - various methods and properties on Entities, replaced by cw_edited and cw_attr_cache
-  - 'commit_event' method on hooks, replaced by 'postcommit_event'
-  - server.hook.set_operation(), replaced by Operation.get_instance(...).add_data()
-  - View.div_id(), View.div_class() and View.create_url()
-  - `*VComponent` classes
-  - in forms, Field.value() and Field.help() must take the form and the field itself as arguments
-  - form.render() must get `w` as a named argument, and renderer.render() must take `w` as first argument
-  - in breadcrumbs, the optional `recurs` argument must be a set, not False
-  - cubicweb.web.views.idownloadable.{download_box,IDownloadableLineView}
-  - primary views no longer have `render_entity_summary` and `summary` methods
-  - WFHistoryVComponent's `cell_call` method is replaced by `render_body`
-  - cubicweb.dataimport.ObjectStore.add(), replaced by create_entity
-  - ManageView.{folders,display_folders}
