Django 今天发布了两个 bug 修复版本 Django 1.8.1 和 Django 1.7.8。 Django 1.8.1 修复了 1.8 的一些 bugs，同时优化了迁移框架： Bug 修复 Added support for serializing timedelta objects in migrations (#24566). Restored proper parsing of the testserver command’s positional arguments (fixture names) (#24571). Prevented TypeError in translation functions check_for_language() andget_language_bidi() when translations are deactivated (#24569). Fixed squashmigrations command when usingSeparateDatabaseAndState(#24278). Stripped microseconds from datetime values when using an older version of the MySQLdb DB API driver as it does not support fractional seconds (#24584). Fixed a migration crash when alteringManyToManyFields (#24513). Fixed a crash with QuerySet.update() on foreign keys to one-to-one fields (#24578). Fixed a regression in the model detail view ofadmindocs when a model has a reverse foreign key relation (#24624). Prevented arbitrary file inclusions in admindocs(#24625). Fixed a crash with QuerySet.update() on foreign keys to instances withuuid primary keys (#24611). Fixed database introspection with SQLite 3.8.9 (released April 8, 2015) (#24637). Updated urlpatterns examples generated by startproject to remove usage of referencing views by dotted path inurl() 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 null/not null column properties during field alteration of MySQL databases (#24595). Fixed JavaScript path of contrib.admin’s related field widget when using alternate static file storages (#24655). Fixed a migration crash when adding new relations to models (#24573). Fixed a migration crash when applying migrations with model managers on Python 3 that were generated on Python 2 (#24701). Restored the ability to use iterators as queryset filter arguments (#24719). Fixed a migration crash when renaming the target model of a many-to-many relation (#24725). Removed flushing of the test database with --keepdb, which prevented apps with data migrations from using the option (#24729). Fixed makemessages crash in some locales (#23271). Fixed help text positioning of contrib.admin fields that use theModelAdmin.filter_horizontal and filter_vertical options (#24676). FixedAttributeError: function ‘GDALAllRegister’ not founderror when initializing contrib.gis on Windows. 优化 Changed ModelState to deepcopy fields instead of deconstructing and reconstructing (#24591). This speeds up the rendering of model states and reduces memory usage when running manage.py migrate. Django 1.7.8 主要是 bug 修复： Database introspection with SQLite 3.8.9 (released April 8, 2015) (#24637). A database table name quoting regression in 1.7.2 (#24605).
