once kwarg in event funcs is new in 0.9.4

2014-05-29T17:43:13+00:00

Document once kwarg in event.listen and event.listen_for as being present in 0.9.4 instead of 0.9.3, testing and changelog agree with me

- disable the scrolling layout, anchors for code/params are not working,

2014-05-29T16:29:02+00:00

and the current approach used for sections is not able to work for fine-grained
anchors like these, another approach needs to be taken.

- Fixed a few edge cases which arise in the so-called "row switch"

2014-05-29T00:01:49+00:00

scenario, where an INSERT/DELETE can be turned into an UPDATE.
In this situation, a many-to-one relationship set to None, or
in some cases a scalar attribute set to None, may not be detected
as a net change in value, and therefore the UPDATE would not reset
what was on the previous row.   This is due to some as-yet
unresovled side effects of the way attribute history works in terms
of implicitly assuming None isn't really a "change" for a previously
un-set attribute.  See also :ticket:`3061`. fixes #3060

- a rework of doc layout and nav:

2014-05-28T14:59:07+00:00

  - reduce the real estate for the top nav; move the search box
    into the top yellow box, close in space
  - use a new CSS/js approach such that the top toolbar freezes from
    scrolling at the top of the page.  The left nav scrolls independently
    of the content pane so that the local contents remain visible regardless
    of scrolling.   this approach is disabled on mobile where the dual scrollbars
    may be cumbersome (overall the site is not well designed for mobile).

- Fixed bug in INSERT..FROM SELECT construct where selecting from a

2014-05-25T18:09:08+00:00

UNION would wrap the union in an anonymous (e.g. unlabled) subquery.
fixes #3044

- Added the ``hashable=False`` flag to the PG :class:`.HSTORE` type, which

2014-05-25T17:58:31+00:00

is needed to allow the ORM to skip over trying to "hash" an ORM-mapped
HSTORE column when requesting it in a mixed column/entity list.
Patch courtesy Gunnlaugur Þór Briem.  Fixes #3053

- Fixed bug in subquery eager loading where a long chain of

2014-05-25T17:46:01+00:00

eager loads across a polymorphic-subclass boundary in conjunction
with polymorphic loading would fail to locate the subclass-link in the
chain, erroring out with a missing property name on an
:class:`.AliasedClass`. fixes #3055

- Fixed bug in SQLite join rewriting where anonymized column names

2014-05-25T15:32:36+00:00

due to repeats would not correctly be rewritten in subqueries.
This would affect SELECT queries with any kind of subquery + join.
fixes #3057

- indicate all 0.9.5 issues as from 1.0.0 backported to 0.9.5

2014-05-24T19:15:20+00:00

- Fixed bug where the :meth:`.Operators.and`,

2014-05-24T18:42:21+00:00

:meth:`.Operators.__or__` and :meth:`.Operators.__invert__`
operator overload methods could not be overridden within a custom
:class:`.TypeEngine.Comparator` implementation.
fixes #3012
