-----
-- removed regular expression step from most statement compilations.
- also fixes [ticket:833]
+- sql
-- Added test coverage for unknown type reflection, fixed sqlite/mysql
- handling of type reflection for unknown types.
+ - Added contains operator (generates a "LIKE %<other>%" clause).
-- Fixed empty (zero column) sqlite inserts, allowing inserts on
- autoincrementing single column tables.
+ - Removed regular expression step from most statement compilations.

-- fixed expression translation of text() clauses; this repairs various
- ORM scenarios where literal text is used for SQL expressions
+ - Fixed expression translation of text() clauses; this repairs various
+ ORM scenarios where literal text is used for SQL expressions
-- sqlite will reflect "DECIMAL" as a numeric column.
+ - Removed ClauseParameters object; compiled.params returns a regular
+ dictionary now, as well as result.last_inserted_params() /
+ last_updated_params().
-- Added experimental support for MaxDB (versions >= 7.6.03.007 only).
+ - Fixed INSERT statements w.r.t. primary key columns that have
+ SQL-expression based default generators on them; SQL expression
+ executes inline as normal but will not trigger a "postfetch" condition
+ for the column, for those DB's who provide it via cursor.lastrowid
-- Made access dao detection more reliable [ticket:828]
+- orm
-- Removed unused util.hash().
+ - Mapped classes may now define __eq__, __hash__, and __nonzero__ methods
+ with arbitrary sementics. The orm now handles all mapped instances on
+ an identity-only basis. (e.g. 'is' vs '==') [ticket:676]
-- removed ClauseParameters object; compiled.params returns a regular dictionary
- now, as well as result.last_inserted_params()/last_updated_params().

+ - The behavior of query.options() is now fully based on paths, i.e. an
+ option such as eagerload_all('x.y.z.y.x') will apply eagerloading to
+ only those paths, i.e. and not 'x.y.x'; eagerload('children.children')
+ applies only to exactly two-levels deep, etc. [ticket:777]
-- Renamed the Dialect attribute 'preexecute_sequences' to
- 'preexecute_pk_sequences'. An attribute proxy is in place for out-of-tree
- dialects using the old name.
+ - The session API has been solidified:

- - Mapped classes may now define __eq__, __hash__, and __nonzero__ methods
- with arbitrary sementics. The orm now handles all mapped instances on
- an identity-only basis. (e.g. 'is' vs '==') [ticket:676]
+ - It's an error to session.save() an object which is already
+ persistent [ticket:840]
- - deferred column attributes no longer trigger a load operation when the
- attribute is assigned to. in those cases, the newly assigned
- value will be present in the flushes' UPDATE statement unconditionally.
-
- - de-cruftified backref configuration code, backrefs which step on existing
- properties now raise an error [ticket:832]
+ - It's an error to session.delete() an object which is *not*
+ persistent.
- - improved behavior of add_property() etc., fixed [ticket:831] involving
- synonym/deferred
+ - session.update() and session.delete() raise an error when updating
+ or deleting an instance that is already in the session with a
+ different identity.
- - fixed clear_mappers() behavior to better clean up after itself
+ - The session checks more carefully when determining "object X already
+ in another session"; e.g. if you pickle a series of objects and
+ unpickle (i.e. as in a Pylons HTTP session or similar), they can go
+ into a new session without any conflict
- - fix to "row switch" behavior, i.e. when an INSERT/DELETE is combined into a
- single UPDATE; many-to-many relations on the parent object update properly.
- [ticket:841]
+ - merge() includes a keyword argument "dont_load=True". setting this
+ flag will cause the merge operation to not load any data from the
+ database in response to incoming detached objects, and will accept
+ the incoming detached object as though it were already present in
+ that session. Use this to merge detached objects from external
+ caching systems into the session.

- - Fixed __hash__ for association proxy- these collections are unhashable,
- just like their mutable Python counterparts.
+ - Fixed a truncation error when re-assigning a subset of a collection
+ (obj.relation = obj.relation[1:]) [ticket:834]
