QuerySet.update()on foreign keys to instances withuuidprimary keys (#24611). - Fixed database introspection with SQLite 3.8.9 (released April 8, 2015) (#24637).
- Updated
urlpatternsexamples generated bystartprojectto remove usage of referencing views by dotted path indjango.conf.urls.url()which is deprecated in Django 1.8 (#24635). - Fixed queries where an expression was referenced in
order_by(), but wasn't part of the select clause. An example query isqs.annotate(foo=F('field')).values('pk').order_by('foo'))(#24615). - Fixed a database table name quoting regression (#24605).
- Prevented the loss of

- Fixed a migration crash when renaming the target model of a many-to-many relation (#24725).
- Removed flushing of the test database with

contrib.adminfields that use theModelAdmin.filter_horizontalandfilter_verticaloptions (#24676). - Fixed
AttributeError: function 'GDALAllRegister' not founderror when initializingcontrib.gison Windows.
Optimizations
- Changed
ModelStateto deepcopy fields instead of deconstructing and reconstructing (#24591). This speeds up the rendering of model states and reduces memory usage when runningmanage.py migrate(although other changes in this release may negate any performance benefits).
