Django 1.11.5 fixes a security issue and several bugs in 1.11.4.

## CVE-2017-12794: Possible XSS in traceback section of technical 500 debug page

In older versions, HTML autoescaping was disabled in a portion of the template for the technical 500 debug page. Given the right circumstances, this allowed a cross-site scripting attack. This vulnerability shouldn’t affect most production sites since you shouldn’t run with `DEBUG = True` (which makes this page accessible) in your production settings.

## Correction de bogues

- Fixed GEOS version parsing if the version has a commit hash at the end (new in GEOS 3.6.2) (#28441).

- Added compatibility for `cx_Oracle` 6 (#28498).

- Fixed select widget rendering when option values are tuples (#28502).

- Django 1.11 inadvertently changed the sequence and trigger naming scheme on Oracle. This causes errors on INSERTs for some tables if `'use_returning_into': False` is in the `OPTIONS` part of `DATABASES`. The pre-1.11 naming scheme is now restored. Unfortunately, it necessarily requires an update to Oracle tables created with Django 1.11.[1-4]. Use the upgrade script in #28451 comment 8 to update sequence and trigger names to use the pre-1.11 naming scheme.

- Added POST request support to `LogoutView`, for equivalence with the function-based `logout()` view (#28513).

- Omitted `pages_per_range` from `BrinIndex.deconstruct()` if it’s `None` (#25809).

- Fixed a regression where `SelectDateWidget` localized the years in the select box (#28530).

- Fixed a regression in 1.11.4 where `runserver` crashed with non-Unicode system encodings on Python 2 + Windows (#28487).

- Fixed a regression in Django 1.10 where changes to a `ManyToManyField` weren’t logged in the admin change history (#27998) and prevented `ManyToManyField` initial data in model forms from being affected by subsequent model changes (#28543).

- Fixed non-deterministic results or an `AssertionError` crash in some queries with multiple joins (#26522).

- Fixed a regression in `contrib.auth`’s `login()` and `logout()` views where they ignored positional arguments (#28550).
