Django 1.7.1 risolve alcuni bug in 1.7.

## Correzioni di bug

- Allowed related many-to-many fields to be referenced in the admin (#23604).

- Added a more helpful error message if you try to migrate an app without first creating the `contenttypes` table (#22411).

- Modified migrations dependency algorithm to avoid possible infinite recursion.

- Fixed a `UnicodeDecodeError` when the `flush` error message contained Unicode characters (#22882).

- Reinstated missing `CHECK` SQL clauses which were omitted on some backends when not using migrations (#23416).

- Fixed serialization of `type` objects in migrations (#22951).

- Allowed inline and hidden references to admin fields (#23431).

- The `@deconstructible` decorator now fails with a `ValueError` if the decorated object cannot automatically be imported (#23418).

- Fixed a typo in an `inlineformset_factory()` error message that caused a crash (#23451).

- Restored the ability to use `ABSOLUTE_URL_OVERRIDES` with the `'auth.User'` model (#11775). As a side effect, the setting now adds a `get_absolute_url()` method to any model that appears in `ABSOLUTE_URL_OVERRIDES` but doesn’t define `get_absolute_url()`.

- Avoided masking some `ImportError` exceptions during application loading (#22920).

- Empty `index_together` or `unique_together` model options no longer results in infinite migrations (#23452).

- Fixed crash in `contrib.sitemaps` if `lastmod` returned a `date` rather than a `datetime` (#23403).

- Allowed migrations to work with `app_label`s that have the same last part (e.g. `django.contrib.auth` and `vendor.auth`) (#23483).

- Restored the ability to deepcopy `F` objects (#23492).

- Formats for Welsh (`cy`) and several Chinese locales (`zh_CN`, `zh_Hans`, `zh_Hant` and `zh_TW`) have been added. Formats for Macedonian have been fixed (trailing dot removed, #23532).

- Added quoting of constraint names in the SQL generated by migrations to prevent crash with uppercase characters in the name (#23065).

- Fixed renaming of models with a self-referential many-to-many field (`ManyToManyField('self')`) (#23503).

- Added the `get_extra()`, `get_max_num()`, and `get_min_num()` hooks to `GenericInlineModelAdmin` (#23539).

- Made `migrations.RunSQL` no longer require percent sign escaping. This is now consistent with `cursor.execute()` (#23426).

- Made the `SERIALIZE` entry in the `TEST` dictionary usable (#23421).

- Fixed bug in migrations that prevented foreign key constraints to unmanaged models with a custom primary key (#23415).

- Added `SchemaEditor` for MySQL GIS backend so that spatial indexes will be created for apps with migrations (#23538).

- Added `SchemaEditor` for Oracle GIS backend so that spatial metadata and indexes will be created for apps with migrations (#23537).

- Coerced the `related_name` model field option to Unicode during migration generation to generate migrations that work with both Python 2 and 3 (#23455).

- Fixed `MigrationWriter` to handle builtin types without imports (#23560).

- Fixed `deepcopy` on `ErrorList` (#23594).

- Made the `admindocs` view to browse view details check if the view specified in the URL exists in the URLconf. Previously it was possible to import arbitrary packages from the Python path. This was not considered a security issue because `admindocs` is only accessible to staff users (#23601).

- Fixed `UnicodeDecodeError` crash in `AdminEmailHandler` with non-ASCII characters in the request (#23593).

- Fixed missing `get_or_create` and `update_or_create` on related managers causing `IntegrityError` (#23611).

- Made `urlsafe_base64_decode()` return the proper type (bytestring) on Python 3 (#23333).

- `makemigrations` can now serialize timezone-aware values (#23365).

- Added a prompt to the migrations questioner when removing the null constraint from a field to prevent an IntegrityError on existing NULL rows (#23609).

- Fixed generic relations in `ModelAdmin.list_filter` (#23616).

- Restored RFC compliance for the SMTP backend on Python 3 (#23063).

- Fixed a crash while parsing cookies containing invalid content (#23638).

- The system check framework now raises error models.E020 when the class method `Model.check()` is unreachable (#23615).

- Made the Oracle test database creation drop the test user in the event of an unclean exit of a previous test run (#23649).

- Fixed `makemigrations` to detect changes to `Meta.db_table` (#23629).

- Fixed a regression when feeding the Django test client with an empty data string (#21740).

- Fixed a regression in `makemessages` where static files were unexpectedly ignored (#23583).
