2.0

========================

December 2, 2017

Welcome to Django 2.0!

These release notes cover the :ref:new features <whats-new-2.0>, as well as
some :ref:backwards incompatible changes <backwards-incompatible-2.0> you'll
want to be aware of when upgrading from Django 1.11 or earlier. We've
:ref:dropped some features<removed-features-2.0> that have reached the end of
their deprecation cycle, and we've :ref:begun the deprecation process for some features <deprecated-features-2.0>.

This release starts Django's use of a :ref:loose form of semantic versioning <internal-release-cadence>, but there aren't any major backwards incompatible
changes that might be expected of a 2.0 release. Upgrading should be a similar
amount of effort as past feature releases.

See the :doc:/howto/upgrade-version guide if you're updating an existing
project.

Python compatibility

Django 2.0 supports Python 3.4, 3.5, and 3.6. We highly recommend and only
officially support the latest release of each series.

The Django 1.11.x series is the last to support Python 2.7.

Django 2.0 will be the last release series to support Python 3.4. If you plan
a deployment of Python 3.4 beyond the end-of-life for Django 2.0 (April 2019),
stick with Django 1.11 LTS (supported until April 2020) instead. Note, however,
that the end-of-life for Python 3.4 is March 2019.

Third-party library support for older version of Django

Following the release of Django 2.0, we suggest that third-party app authors
drop support for all versions of Django prior to 1.11. At that time, you should
be able to run your package's tests using python -Wd so that deprecation
warnings do appear. After making the deprecation warning fixes, your app should
be compatible with Django 2.0.

.. _whats-new-2.0:

What's new in Django 2.0

Simplified URL routing syntax

The new :func:django.urls.path() function allows a simpler, more readable URL
routing syntax. For example, this example from previous Django releases::

url(r'^articles/(?P<year>[0-9]{4})/$', views.year_archive),

could be written as::

path('articles/<int:year>/', views.year_archive),

The new syntax supports type coercion of URL parameters. In the example, the
view will receive the year keyword argument as an integer rather than as
a string. Also, the URLs that will match are slightly less constrained in the
rewritten example. For example, the year 10000 will now match since the year
integers aren't constrained to be exactly four digits long as they are in the
regular expression.

The django.conf.urls.url() function from previous versions is now available
as :func:django.urls.re_path. The old location remains for backwards
compatibility, without an imminent deprecation. The old
django.conf.urls.include() function is now importable from django.urls
so you can use from django.urls import include, path, re_path in your
URLconfs.

The :doc:/topics/http/urls document is rewritten to feature the new syntax
and provide more details.

Mobile-friendly contrib.admin

The admin is now responsive and supports all major mobile devices. Older
browsers may experience varying levels of graceful degradation.

Window expressions

The new :class:~django.db.models.expressions.Window expression allows
adding an OVER clause to querysets. You can use :ref:window functions <window-functions> and :ref:aggregate functions <aggregation-functions> in
the expression.

Minor features

:mod:django.contrib.admin

• The new :attr:.ModelAdmin.autocomplete_fields attribute and
  :meth:.ModelAdmin.get_autocomplete_fields method allow using an
  Select2 <https://select2.org>_ search widget for ForeignKey and
  ManyToManyField.

:mod:django.contrib.auth

• The default iteration count for the PBKDF2 password hasher is increased from
  36,000 to 100,000.

:mod:django.contrib.gis

• Added MySQL support for the
  :class:~django.contrib.gis.db.models.functions.AsGeoJSON function,
  :class:~django.contrib.gis.db.models.functions.GeoHash function,
  :class:~django.contrib.gis.db.models.functions.IsValid function,
  :lookup:isvalid lookup, and :ref:distance lookups <distance-lookups>.

• Added the :class:~django.contrib.gis.db.models.functions.Azimuth and
  :class:~django.contrib.gis.db.models.functions.LineLocatePoint functions,
  supported on PostGIS and SpatiaLite.

• Any :class:~django.contrib.gis.geos.GEOSGeometry imported from GeoJSON now
  has its SRID set.

• Added the :attr:.OSMWidget.default_zoom attribute to customize the map's
  default zoom level.

• Made metadata readable and editable on rasters through the
  :attr:~django.contrib.gis.gdal.GDALRaster.metadata,
  :attr:~django.contrib.gis.gdal.GDALRaster.info, and
  :attr:~django.contrib.gis.gdal.GDALBand.metadata attributes.

• Allowed passing driver-specific creation options to
  :class:~django.contrib.gis.gdal.GDALRaster objects using papsz_options.

• Allowed creating :class:~django.contrib.gis.gdal.GDALRaster objects in
  GDAL's internal virtual filesystem. Rasters can now be :ref:created from and converted to binary data <gdal-raster-vsimem> in-memory.

• The new :meth:GDALBand.color_interp() <django.contrib.gis.gdal.GDALBand.color_interp> method returns the color
  interpretation for the band.

:mod:django.contrib.postgres

• The new distinct argument for
  :class:~django.contrib.postgres.aggregates.ArrayAgg determines if
  concatenated values will be distinct.

• The new :class:~django.contrib.postgres.functions.RandomUUID database
  function returns a version 4 UUID. It requires use of PostgreSQL's
  pgcrypto extension which can be activated using the new
  :class:~django.contrib.postgres.operations.CryptoExtension migration
  operation.

• :class:django.contrib.postgres.indexes.GinIndex now supports the
  fastupdate and gin_pending_list_limit parameters.

• The new :class:~django.contrib.postgres.indexes.GistIndex class allows
  creating GiST indexes in the database. The new
  :class:~django.contrib.postgres.operations.BtreeGistExtension migration
  operation installs the btree_gist extension to add support for operator
  classes that aren't built-in.

• :djadmin:inspectdb can now introspect JSONField and various
  RangeField\s (django.contrib.postgres must be in INSTALLED_APPS).

:mod:django.contrib.sitemaps

• Added the protocol keyword argument to the
  :class:~django.contrib.sitemaps.GenericSitemap constructor.

Cache

• cache.set_many() now returns a list of keys that failed to be inserted.
  For the built-in backends, failed inserts can only happen on memcached.

File Storage

• :meth:File.open() <django.core.files.File.open> can be used as a context
  manager, e.g. with file.open() as f:.

Forms

• The new date_attrs and time_attrs arguments for
  :class:~django.forms.SplitDateTimeWidget and
  :class:~django.forms.SplitHiddenDateTimeWidget allow specifying different
  HTML attributes for the DateInput and TimeInput (or hidden)
  subwidgets.

• The new :meth:Form.errors.get_json_data() <django.forms.Form.errors.get_json_data> method returns form errors as
  a dictionary suitable for including in a JSON response.

Generic Views

• The new :attr:.ContextMixin.extra_context attribute allows adding context
  in View.as_view().

Management Commands

• :djadmin:inspectdb now translates MySQL's unsigned integer columns to
  PositiveIntegerField or PositiveSmallIntegerField.

• The new :option:makemessages --add-location option controls the comment
  format in PO files.

• :djadmin:loaddata can now :ref:read from stdin <loading-fixtures-stdin>.

• The new :option:diffsettings --output option allows formatting the output
  in a unified diff format.

• On Oracle, :djadmin:inspectdb can now introspect AutoField if the
  column is created as an identity column.

• On MySQL, :djadmin:dbshell now supports client-side TLS certificates.

Migrations

• The new :option:squashmigrations --squashed-name option allows naming the
  squashed migration.

Models

• The new :class:~django.db.models.functions.StrIndex database function
  finds the starting index of a string inside another string.

• On Oracle, AutoField and BigAutoField are now created as identity columns_.

.. _identity columns: https://docs.oracle.com/database/121/DRDAA/migr_tools_feat.htmDRDAA109

• The new chunk_size parameter of :meth:.QuerySet.iterator controls the
  number of rows fetched by the Python database client when streaming results
  from the database. For databases that don't support server-side cursors, it
  controls the number of results Django fetches from the database adapter.

• :meth:.QuerySet.earliest, :meth:.QuerySet.latest, and
  :attr:Meta.get_latest_by <django.db.models.Options.get_latest_by> now
  allow ordering by several fields.

• Added the :class:~django.db.models.functions.ExtractQuarter function to
  extract the quarter from :class:~django.db.models.DateField and
  :class:~django.db.models.DateTimeField, and exposed it through the
  :lookup:quarter lookup.

• Added the :class:~django.db.models.functions.TruncQuarter function to
  truncate :class:~django.db.models.DateField and
  :class:~django.db.models.DateTimeField to the first day of a quarter.

• Added the :attr:~django.db.models.Index.db_tablespace parameter to
  class-based indexes.

• If the database supports a native duration field (Oracle and PostgreSQL),
  :class:~django.db.models.functions.Extract now works with
  :class:~django.db.models.DurationField.

• Added the of argument to :meth:.QuerySet.select_for_update(), supported
  on PostgreSQL and Oracle, to lock only rows from specific tables rather than
  all selected tables. It may be helpful particularly when
  :meth:~.QuerySet.select_for_update() is used in conjunction with
  :meth:~.QuerySet.select_related().

• The new field_name parameter of :meth:.QuerySet.in_bulk allows fetching
  results based on any unique model field.

• :meth:.CursorWrapper.callproc() now takes an optional dictionary of keyword
  parameters, if the backend supports this feature. Of Django's built-in
  backends, only Oracle supports it.

• The new :meth:connection.execute_wrapper() <django.db.backends.base.DatabaseWrapper.execute_wrapper> method allows
  :doc:installing wrappers around execution of database queries </topics/db/instrumentation>.

• The new filter argument for built-in aggregates allows :ref:adding different conditionals <conditional-aggregation> to multiple aggregations
  over the same fields or relations.

• Added support for expressions in :attr:Meta.ordering <django.db.models.Options.ordering>.

• The new named parameter of :meth:.QuerySet.values_list allows fetching
  results as named tuples.

• The new :class:.FilteredRelation class allows adding an ON clause to
  querysets.

Pagination

• Added :meth:Paginator.get_page() <django.core.paginator.Paginator.get_page>
  to provide the documented pattern of handling invalid page numbers.

Requests and Responses

• The :djadmin:runserver Web server supports HTTP 1.1.

Templates

• To increase the usefulness of :meth:.Engine.get_default in third-party
  apps, it now returns the first engine if multiple DjangoTemplates engines
  are configured in TEMPLATES rather than raising ImproperlyConfigured.

• Custom template tags may now accept keyword-only arguments.

Tests

• Added threading support to :class:~django.test.LiveServerTestCase.

• Added settings that allow customizing the test tablespace parameters for
  Oracle: :setting:DATAFILE_SIZE, :setting:DATAFILE_TMP_SIZE,
  :setting:DATAFILE_EXTSIZE, and :setting:DATAFILE_TMP_EXTSIZE.

Validators

• The new :class:.ProhibitNullCharactersValidator disallows the null
  character in the input of the :class:~django.forms.CharField form field
  and its subclasses. Null character input was observed from vulnerability
  scanning tools. Most databases silently discard null characters, but
  psycopg2 2.7+ raises an exception when trying to save a null character to
  a char/text field with PostgreSQL.

.. _backwards-incompatible-2.0:

Backwards incompatible changes in 2.0

Removed support for bytestrings in some places

To support native Python 2 strings, older Django versions had to accept both
bytestrings and unicode strings. Now that Python 2 support is dropped,
bytestrings should only be encountered around input/output boundaries (handling
of binary fields or HTTP streams, for example). You might have to update your
code to limit bytestring usage to a minimum, as Django no longer accepts
bytestrings in certain code paths.

For example, reverse() now uses str() instead of force_text() to
coerce the args and kwargs it receives, prior to their placement in
the URL. For bytestrings, this creates a string with an undesired b prefix
as well as additional quotes (str(b'foo') is "b'foo'"). To adapt, call
decode() on the bytestring before passing it to reverse().

Database backend API

This section describes changes that may be needed in third-party database
backends.

• The DatabaseOperations.datetime_cast_date_sql(),
  datetime_cast_time_sql(), datetime_trunc_sql(),
  datetime_extract_sql(), and date_interval_sql() methods now return
  only the SQL to perform the operation instead of SQL and a list of
  parameters.

• Third-party database backends should add a DatabaseWrapper.display_name
  attribute with the name of the database that your backend works with. Django
  may use it in various messages, such as in system checks.

• The first argument of SchemaEditor._alter_column_type_sql() is now
  model rather than table.

• The first argument of SchemaEditor._create_index_name() is now
  table_name rather than model.

• To enable FOR UPDATE OF support, set
  DatabaseFeatures.has_select_for_update_of = True. If the database
  requires that the arguments to OF be columns rather than tables, set
  DatabaseFeatures.select_for_update_of_column = True.

• To enable support for :class:~django.db.models.expressions.Window
  expressions, set DatabaseFeatures.supports_over_clause to True. You
  may need to customize the DatabaseOperations.window_start_rows_start_end()
  and/or window_start_range_start_end() methods.

• Third-party database backends should add a
  DatabaseOperations.cast_char_field_without_max_length attribute with the
  database data type that will be used in the
  :class:~django.db.models.functions.Cast function for a CharField if the
  max_length argument isn't provided.

• The first argument of DatabaseCreation._clone_test_db() and
  get_test_db_clone_settings() is now suffix rather
  than number (in case you want to rename the signatures in your backend
  for consistency). django.test also now passes those values as strings
  rather than as integers.

• Third-party database backends should add a
  DatabaseIntrospection.get_sequences() method based on the stub in
  BaseDatabaseIntrospection.

Dropped support for Oracle 11.2

The end of upstream support for Oracle 11.2 is Dec. 2020. Django 1.11 will be
supported until April 2020 which almost reaches this date. Django 2.0
officially supports Oracle 12.1+.

Default MySQL isolation level is read committed

MySQL's default isolation level, repeatable read, may cause data loss in
typical Django usage. To prevent that and for consistency with other databases,
the default isolation level is now read committed. You can use the
:setting:DATABASES setting to :ref:use a different isolation level <mysql-isolation-level>, if needed.

:attr:AbstractUser.last_name <django.contrib.auth.models.User.last_name> max_length increased to 150

A migration for :attr:django.contrib.auth.models.User.last_name is included.
If you have a custom user model inheriting from AbstractUser, you'll need
to generate and apply a database migration for your user model.

If you want to preserve the 30 character limit for last names, use a custom
form::

from django.contrib.auth.forms import UserChangeForm

class MyUserChangeForm(UserChangeForm):
last_name = forms.CharField(max_length=30, required=False)

If you wish to keep this restriction in the admin when editing users, set
UserAdmin.form to use this form::

from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.models import User

class MyUserAdmin(UserAdmin):
form = MyUserChangeForm

admin.site.unregister(User)
admin.site.register(User, MyUserAdmin)

QuerySet.reverse() and last() are prohibited after slicing

Calling QuerySet.reverse() or last() on a sliced queryset leads to
unexpected results due to the slice being applied after reordering. This is
now prohibited, e.g.::

>>> Model.objects.all()[:2].reverse()
Traceback (most recent call last):
...
TypeError: Cannot reverse a query once a slice has been taken.

Form fields no longer accept optional arguments as positional arguments

To help prevent runtime errors due to incorrect ordering of form field
arguments, optional arguments of built-in form fields are no longer accepted
as positional arguments. For example::

forms.IntegerField(25, 10)

raises an exception and should be replaced with::

forms.IntegerField(max_value=25, min_value=10)

call_command() validates the options it receives

call_command() now validates that the argument parser of the command being
called defines all of the options passed to call_command().

For custom management commands that use options not created using
parser.add_argument(), add a stealth_options attribute on the command::

class MyCommand(BaseCommand):
stealth_options = ('option_name', ...)

Indexes no longer accept positional arguments

For example::

models.Index(['headline', '-pub_date'], 'index_name')

raises an exception and should be replaced with::

models.Index(fields=['headline', '-pub_date'], name='index_name')

Foreign key constraints are now enabled on SQLite

This will appear as a backwards-incompatible change (IntegrityError: FOREIGN KEY constraint failed) if attempting to save an existing model
instance that's violating a foreign key constraint.

Foreign keys are now created with DEFERRABLE INITIALLY DEFERRED instead of
DEFERRABLE IMMEDIATE. Thus, tables may need to be rebuilt to recreate
foreign keys with the new definition, particularly if you're using a pattern
like this::

from django.db import transaction

with transaction.atomic():
Book.objects.create(author_id=1)
Author.objects.create(id=1)

If you don't recreate the foreign key as DEFERRED, the first create()
would fail now that foreign key constraints are enforced.

Backup your database first! After upgrading to Django 2.0, you can then
rebuild tables using a script similar to this::

from django.apps import apps
from django.db import connection

for app in apps.get_app_configs():
for model in app.get_models(include_auto_created=True):
if model._meta.managed and not (model._meta.proxy or model._meta.swapped):
for base in model.bases:
if hasattr(base, '_meta'):
base._meta.local_many_to_many = []
model._meta.local_many_to_many = []
with connection.schema_editor() as editor:
editor._remake_table(model)

This script hasn't received extensive testing and needs adaption for various
cases such as multiple databases. Feel free to contribute improvements.

In addition, because of a table alteration limitation of SQLite, it's prohibited
to perform :class:~django.db.migrations.operations.RenameModel and
:class:~django.db.migrations.operations.RenameField operations on models or
fields referenced by other models in a transaction. In order to allow migrations
containing these operations to be applied, you must set the
Migration.atomic attribute to False.

Miscellaneous

• The SessionAuthenticationMiddleware class is removed. It provided no
  functionality since session authentication is unconditionally enabled in
  Django 1.10.

• The default HTTP error handlers (handler404, etc.) are now callables
  instead of dotted Python path strings. Django favors callable references
  since they provide better performance and debugging experience.

• :class:~django.views.generic.base.RedirectView no longer silences
  NoReverseMatch if the pattern_name doesn't exist.

• When :setting:USE_L10N is off, :class:~django.forms.FloatField and
  :class:~django.forms.DecimalField now respect :setting:DECIMAL_SEPARATOR
  and :setting:THOUSAND_SEPARATOR during validation. For example, with the
  settings::

USE_L10N = False
USE_THOUSAND_SEPARATOR = True
DECIMAL_SEPARATOR = ','
THOUSAND_SEPARATOR = '.'

an input of "1.345" is now converted to 1345 instead of 1.345.

• Subclasses of :class:~django.contrib.auth.models.AbstractBaseUser are no
  longer required to implement get_short_name() and get_full_name().
  (The base implementations that raise NotImplementedError are removed.)
  django.contrib.admin uses these methods if implemented but doesn't
  require them. Third-party apps that use these methods may want to adopt a
  similar approach.

• The FIRST_DAY_OF_WEEK and NUMBER_GROUPING format settings are now
  kept as integers in JavaScript and JSON i18n view outputs.

• :meth:~django.test.TransactionTestCase.assertNumQueries now ignores
  connection configuration queries. Previously, if a test opened a new database
  connection, those queries could be included as part of the
  assertNumQueries() count.

• The default size of the Oracle test tablespace is increased from 20M to 50M
  and the default autoextend size is increased from 10M to 25M.

• To improve performance when streaming large result sets from the database,
  :meth:.QuerySet.iterator now fetches 2000 rows at a time instead of 100.
  The old behavior can be restored using the chunk_size parameter. For
  example::

 Book.objects.iterator(chunk_size=100)

• Providing unknown package names in the packages argument of the
  :class:~django.views.i18n.JavaScriptCatalog view now raises ValueError
  instead of passing silently.

• A model instance's primary key now appears in the default Model.__str__()
  method, e.g. Question object (1).

• makemigrations now detects changes to the model field limit_choices_to
  option. Add this to your existing migrations or accept an auto-generated
  migration for fields that use it.

• Performing queries that require :ref:automatic spatial transformations <automatic-spatial-transformations> now raises NotImplementedError
  on MySQL instead of silently using non-transformed geometries.

• django.core.exceptions.DjangoRuntimeWarning is removed. It was only used
  in the cache backend as an intermediate class in CacheKeyWarning's
  inheritance of RuntimeWarning.

• Renamed BaseExpression._output_field to output_field. You may need
  to update custom expressions.

• In older versions, forms and formsets combine their Media with widget
  Media by concatenating the two. The combining now tries to :ref:preserve the relative order of elements in each list <form-media-asset-order>.
  MediaOrderConflictWarning is issued if the order can't be preserved.

• django.contrib.gis.gdal.OGRException is removed. It's been an alias for
  GDALException since Django 1.8.

• Support for GEOS 3.3.x is dropped.

• The way data is selected for GeometryField is changed to improve
  performance, and in raw SQL queries, those fields must now be wrapped in
  connection.ops.select. See the :ref:Raw queries note<gis-raw-sql> in
  the GIS tutorial for an example.

.. _deprecated-features-2.0:

Features deprecated in 2.0

context argument of Field.from_db_value() and Expression.convert_value()

The context argument of Field.from_db_value() and
Expression.convert_value() is unused as it's always an empty dictionary.
The signature of both methods is now::

(self, value, expression, connection)

instead of::

(self, value, expression, connection, context)

Support for the old signature in custom fields and expressions remains until
Django 3.0.

Miscellaneous

• The django.db.backends.postgresql_psycopg2 module is deprecated in favor
  of django.db.backends.postgresql. It's been an alias since Django 1.9.
  This only affects code that imports from the module directly. The
  DATABASES setting can still use
  'django.db.backends.postgresql_psycopg2', though you can simplify that by
  using the 'django.db.backends.postgresql' name added in Django 1.9.

• django.shortcuts.render_to_response() is deprecated in favor of
  :func:django.shortcuts.render. render() takes the same arguments
  except that it also requires a request.

• The DEFAULT_CONTENT_TYPE setting is deprecated. It doesn't interact well
  well with third-party apps and is obsolete since HTML5 has mostly superseded
  XHTML.

• HttpRequest.xreadlines() is deprecated in favor of iterating over the
  request.

• The field_name keyword argument to :meth:.QuerySet.earliest and
  :meth:.QuerySet.latest is deprecated in favor of passing the field
  names as arguments. Write .earliest('pub_date') instead of
  .earliest(field_name='pub_date').

.. _removed-features-2.0:

Features removed in 2.0

These features have reached the end of their deprecation cycle and are removed
in Django 2.0.

See :ref:deprecated-features-1.9 for details on these changes, including how
to remove usage of these features.

• The weak argument to django.dispatch.signals.Signal.disconnect() is
  removed.

• django.db.backends.base.BaseDatabaseOperations.check_aggregate_support()
  is removed.

• The django.forms.extras package is removed.

• The assignment_tag helper is removed.

• The host argument to SimpleTestCase.assertsRedirects() is removed.
  The compatibility layer which allows absolute URLs to be considered equal to
  relative ones when the path is identical is also removed.

• Field.rel and Field.remote_field.to are removed.

• The on_delete argument for ForeignKey and OneToOneField is now
  required in models and migrations. Consider squashing migrations so that you
  have less of them to update.

• django.db.models.fields.add_lazy_relation() is removed.

• When time zone support is enabled, database backends that don't support time
  zones no longer convert aware datetimes to naive values in UTC anymore when
  such values are passed as parameters to SQL queries executed outside of the
  ORM, e.g. with cursor.execute().

• django.contrib.auth.tests.utils.skipIfCustomUser() is removed.

• The GeoManager and GeoQuerySet classes are removed.

• The django.contrib.gis.geoip module is removed.

• The supports_recursion check for template loaders is removed from:

• django.template.engine.Engine.find_template()
• django.template.loader_tags.ExtendsNode.find_template()
• django.template.loaders.base.Loader.supports_recursion()
• django.template.loaders.cached.Loader.supports_recursion()

• The load_template and load_template_sources template loader methods
  are removed.

• The template_dirs argument for template loaders is removed:

• django.template.loaders.base.Loader.get_template()
• django.template.loaders.cached.Loader.cache_key()
• django.template.loaders.cached.Loader.get_template()
• django.template.loaders.cached.Loader.get_template_sources()
• django.template.loaders.filesystem.Loader.get_template_sources()

• django.template.loaders.base.Loader.__call__() is removed.

• Support for custom error views that don't accept an exception parameter
  is removed.

• The mime_type attribute of django.utils.feedgenerator.Atom1Feed and
  django.utils.feedgenerator.RssFeed is removed.

• The app_name argument to include() is removed.

• Support for passing a 3-tuple (including admin.site.urls) as the first
  argument to include() is removed.

• Support for setting a URL instance namespace without an application namespace
  is removed.

• Field._get_val_from_obj() is removed.

• django.template.loaders.eggs.Loader is removed.

• The current_app parameter to the contrib.auth function-based views is
  removed.

• The callable_obj keyword argument to
  SimpleTestCase.assertRaisesMessage() is removed.

1.0

Released and unreleased on December 7, 2017. Badly packaged release.

1.0b3

Released on July 24, 2013

• Removed RecursiveTreeWalker from treewalkers._base. Any
  implementation using it should be moved to
  NonRecursiveTreeWalker, as everything bundled with html5lib has
  for years.

• Fix 67 so that BufferedStream to correctly returns a bytes
  object, thereby fixing any case where html5lib is passed a
  non-seekable RawIOBase-like object.

1.0b2

Released on June 27, 2013

• Removed reordering of attributes within the serializer. There is now
  an alphabetical_attributes option which preserves the previous
  behaviour through a new filter. This allows attribute order to be
  preserved through html5lib if the tree builder preserves order.

• Removed dom2sax from DOM treebuilders. It has been replaced by
  treeadapters.sax.to_sax which is generic and supports any
  treewalker; it also resolves all known bugs with dom2sax.

• Fix treewalker assertions on hitting bytes strings on
  Python 2. Previous to 1.0b1, treewalkers coped with mixed
  bytes/unicode data on Python 2; this reintroduces this prior
  behaviour on Python 2. Behaviour is unchanged on Python 3.

1.0b1

Released on May 17, 2013

• Implementation updated to implement the HTML specification <http://www.whatwg.org/specs/web-apps/current-work/>_ as of 5th May
  2013 (SVN <http://svn.whatwg.org/webapps/>_ revision r7867).

• Python 3.2+ supported in a single codebase using the six library.

• Removed support for Python 2.5 and older.

• Removed the deprecated Beautiful Soup 3 treebuilder.
  beautifulsoup4 can use html5lib as a parser instead. Note that
  since it doesn't support namespaces, foreign content like SVG and
  MathML is parsed incorrectly.

• Removed simpletree from the package. The default tree builder is
  now etree (using the xml.etree.cElementTree implementation if
  available, and xml.etree.ElementTree otherwise).

• Removed the XHTMLSerializer as it never actually guaranteed its
  output was well-formed XML, and hence provided little of use.

• Removed default DOM treebuilder, so html5lib.treebuilders.dom is no
  longer supported. html5lib.treebuilders.getTreeBuilder("dom") will
  return the default DOM treebuilder, which uses xml.dom.minidom.

• Optional heuristic character encoding detection now based on
  charade for Python 2.6 - 3.3 compatibility.

• Optional Genshi treewalker support fixed.

• Many bugfixes, including:

• 33: null in attribute value breaks XML AttValue;

• 4: nested, indirect descendant, <button> causes infinite loop;

• Google Code 215 <http://code.google.com/p/html5lib/issues/detail?id=215>_: Properly
  detect seekable streams;

• Google Code 206 <http://code.google.com/p/html5lib/issues/detail?id=206>_: add
  support for <video preload=...>, <audio preload=...>;

• Google Code 205 <http://code.google.com/p/html5lib/issues/detail?id=205>_: add
  support for <video poster=...>;

• Google Code 202 <http://code.google.com/p/html5lib/issues/detail?id=202>_: Unicode
  file breaks InputStream.

• Source code is now mostly PEP 8 compliant.

• Test harness has been improved and now depends on nose.

• Documentation updated and moved to https://html5lib.readthedocs.io/.

numba 0.35.0 -> 0.36.1

0.36.1

---

This release continues to add new features to the work undertaken in partnership
with Intel on ParallelAccelerator technology. Other changes of note include the
compilation chain being updated to use LLVM 5.0 and the production of conda
packages using conda-build 3 and the new compilers that ship with it.

NOTE: A version 0.36.0 was tagged for internal use but not released.

ParallelAccelerator:

NOTE: The ParallelAccelerator technology is under active development and should
be considered experimental.

New features relating to ParallelAccelerator, from work undertaken with Intel,
include the addition of the stencil decorator for ease of implementation of
stencil-like computations, support for general reductions, and slice and
range fusion for parallel slice/bit-array assignments. Documentation on both the
use and implementation of the above has been added. Further, a new debug
environment variable NUMBA_DEBUG_ARRAY_OPT_STATS is made available to give
information about which operators/calls are converted to parallel for-loops.

ParallelAccelerator features:

• PR 2457: Stencil Computations in ParallelAccelerator
• PR 2548: Slice and range fusion, parallelizing bitarray and slice assignment
• PR 2516: Support general reductions in ParallelAccelerator

ParallelAccelerator fixes:

• PR 2540: Fix bug 2537
• PR 2566: Fix issue 2564.
• PR 2599: Fix nested multi-dimensional parfor type inference issue
• PR 2604: Fixes for stencil tests and cmath sin().
• PR 2605: Fixes issue 2603.

Additional features of note:

This release of Numba (and llvmlite) is updated to use LLVM version 5.0 as the
compiler back end, the main change to Numba to support this was the addition of
a custom symbol tracker to avoid the calls to LLVM's ExecutionEngine that was
crashing when asking for non-existent symbol addresses. Further, the conda
packages for this release of Numba are built using conda build version 3 and the
new compilers/recipe grammar that are present in that release.

• PR 2568: Update for LLVM 5
• PR 2607: Fixes abort when getting address to "nrt_unresolved_abort"
• PR 2615: Working towards conda build 3

Thanks to community feedback and bug reports, the following fixes were also
made.

Misc fixes/enhancements:

• PR 2534: Add tuple support to np.take.
• PR 2551: Rebranding fix
• PR 2552: relative doc links
• PR 2570: Fix issue 2561, handle missing successor on loop exit
• PR 2588: Fix 2555. Disable libpython.so linking on linux
• PR 2601: Update llvmlite version dependency.

• PR 2581: Fix cuda gufunc mishandling of scalar arg as array and out argument

pytest 3.2.3 -> 3.3.1

3.3.1

=========================

Bug Fixes

• Fix issue about -p no:<plugin> having no effect. (2920 <https://github.com/pytest-dev/pytest/issues/2920>_)

• Fix regression with warnings that contained non-strings in their arguments in
  Python 2. (2956 <https://github.com/pytest-dev/pytest/issues/2956>_)

• Always escape null bytes when setting PYTEST_CURRENT_TEST. (2957 <https://github.com/pytest-dev/pytest/issues/2957>_)

• Fix ZeroDivisionError when using the testmon plugin when no tests
  were actually collected. (2971 <https://github.com/pytest-dev/pytest/issues/2971>_)

• Bring back TerminalReporter.writer as an alias to
  TerminalReporter._tw. This alias was removed by accident in the 3.3.0
  release. (2984 <https://github.com/pytest-dev/pytest/issues/2984>_)

• The pytest-capturelog plugin is now also blacklisted, avoiding errors when
  running pytest with it still installed. (3004 <https://github.com/pytest-dev/pytest/issues/3004>_)

Improved Documentation

• Fix broken link to plugin pytest-localserver. (2963 <https://github.com/pytest-dev/pytest/issues/2963>_)

Trivial/Internal Changes

• Update github "bugs" link in CONTRIBUTING.rst (2949 <https://github.com/pytest-dev/pytest/issues/2949>_)

3.3.0

=========================

Deprecations and Removals

• Pytest no longer supports Python 2.6 and 3.3. Those Python versions
  are EOL for some time now and incur maintenance and compatibility costs on
  the pytest core team, and following up with the rest of the community we
  decided that they will no longer be supported starting on this version. Users
  which still require those versions should pin pytest to <3.3. (2812 <https://github.com/pytest-dev/pytest/issues/2812>_)

• Remove internal _preloadplugins() function. This removal is part of the
  pytest_namespace() hook deprecation. (2636 <https://github.com/pytest-dev/pytest/issues/2636>_)

• Internally change CallSpec2 to have a list of marks instead of a broken
  mapping of keywords. This removes the keywords attribute of the internal
  CallSpec2 class. (2672 <https://github.com/pytest-dev/pytest/issues/2672>_)

• Remove ParameterSet.deprecated_arg_dict - its not a public api and the lack
  of the underscore was a naming error. (2675 <https://github.com/pytest-dev/pytest/issues/2675>_)

• Remove the internal multi-typed attribute Node._evalskip and replace it
  with the boolean Node._skipped_by_mark. (2767 <https://github.com/pytest-dev/pytest/issues/2767>_)

• The params list passed to pytest.fixture is now for
  all effects considered immutable and frozen at the moment of the pytest.fixture
  call. Previously the list could be changed before the first invocation of the fixture
  allowing for a form of dynamic parametrization (for example, updated from command-line options),
  but this was an unwanted implementation detail which complicated the internals and prevented
  some internal cleanup. See issue 2959 <https://github.com/pytest-dev/pytest/issues/2959>_
  for details and a recommended workaround.

Features

• pytest_fixture_post_finalizer hook can now receive a request
  argument. (2124 <https://github.com/pytest-dev/pytest/issues/2124>_)

• Replace the old introspection code in compat.py that determines the available
  arguments of fixtures with inspect.signature on Python 3 and
  funcsigs.signature on Python 2. This should respect __signature__
  declarations on functions. (2267 <https://github.com/pytest-dev/pytest/issues/2267>_)

• Report tests with global pytestmark variable only once. (2549 <https://github.com/pytest-dev/pytest/issues/2549>_)

• Now pytest displays the total progress percentage while running tests. The
  previous output style can be set by configuring the console_output_style
  setting to classic. (2657 <https://github.com/pytest-dev/pytest/issues/2657>_)

• Match warns signature to raises by adding match keyword. (2708 <https://github.com/pytest-dev/pytest/issues/2708>_)

• Pytest now captures and displays output from the standard logging module.
  The user can control the logging level to be captured by specifying options
  in pytest.ini, the command line and also during individual tests using
  markers. Also, a caplog fixture is available that enables users to test
  the captured log during specific tests (similar to capsys for example).
  For more information, please see the logging docs <https://docs.pytest.org/en/latest/logging.html>. This feature was
  introduced by merging the popular pytest-catchlog <https://pypi.org/project/pytest-catchlog/> plugin, thanks to Thomas Hisch <https://github.com/thisch>. Be advised that during the merging the
  backward compatibility interface with the defunct pytest-capturelog has
  been dropped. (2794 <https://github.com/pytest-dev/pytest/issues/2794>)

• Add allow_module_level kwarg to pytest.skip(), enabling to skip the
  whole module. (2808 <https://github.com/pytest-dev/pytest/issues/2808>_)

• Allow setting file_or_dir, -c, and -o in PYTEST_ADDOPTS. (2824 <https://github.com/pytest-dev/pytest/issues/2824>_)

• Return stdout/stderr capture results as a namedtuple, so out and
  err can be accessed by attribute. (2879 <https://github.com/pytest-dev/pytest/issues/2879>_)

• Add capfdbinary, a version of capfd which returns bytes from
  readouterr(). (2923 <https://github.com/pytest-dev/pytest/issues/2923>_)

• Add capsysbinary a version of capsys which returns bytes from
  readouterr(). (2934 <https://github.com/pytest-dev/pytest/issues/2934>_)

• Implement feature to skip setup.py files when run with
  --doctest-modules. (502 <https://github.com/pytest-dev/pytest/issues/502>_)

Bug Fixes

• Resume output capturing after capsys/capfd.disabled() context manager.
  (1993 <https://github.com/pytest-dev/pytest/issues/1993>_)

• pytest_fixture_setup and pytest_fixture_post_finalizer hooks are now
  called for all conftest.py files. (2124 <https://github.com/pytest-dev/pytest/issues/2124>_)

• If an exception happens while loading a plugin, pytest no longer hides the
  original traceback. In python2 it will show the original traceback with a new
  message that explains in which plugin. In python3 it will show 2 canonized
  exceptions, the original exception while loading the plugin in addition to an
  exception that PyTest throws about loading a plugin. (2491 <https://github.com/pytest-dev/pytest/issues/2491>_)

• capsys and capfd can now be used by other fixtures. (2709 <https://github.com/pytest-dev/pytest/issues/2709>_)

• Internal pytester plugin properly encodes bytes arguments to
  utf-8. (2738 <https://github.com/pytest-dev/pytest/issues/2738>_)

• testdir now uses use the same method used by tmpdir to create its
  temporary directory. This changes the final structure of the testdir
  directory slightly, but should not affect usage in normal scenarios and
  avoids a number of potential problems. (2751 <https://github.com/pytest-dev/pytest/issues/2751>_)

• Pytest no longer complains about warnings with unicode messages being
  non-ascii compatible even for ascii-compatible messages. As a result of this,
  warnings with unicode messages are converted first to an ascii representation
  for safety. (2809 <https://github.com/pytest-dev/pytest/issues/2809>_)

• Change return value of pytest command when --maxfail is reached from
  2 (interrupted) to 1 (failed). (2845 <https://github.com/pytest-dev/pytest/issues/2845>_)

• Fix issue in assertion rewriting which could lead it to rewrite modules which
  should not be rewritten. (2939 <https://github.com/pytest-dev/pytest/issues/2939>_)

• Handle marks without description in pytest.ini. (2942 <https://github.com/pytest-dev/pytest/issues/2942>_)

Trivial/Internal Changes

• pytest now depends on attrs <https://pypi.org/project/attrs/>_ for internal
  structures to ease code maintainability. (2641 <https://github.com/pytest-dev/pytest/issues/2641>_)

• Refactored internal Python 2/3 compatibility code to use six. (2642 <https://github.com/pytest-dev/pytest/issues/2642>_)

• Stop vendoring pluggy - we're missing out on its latest changes for not
  much benefit (2719 <https://github.com/pytest-dev/pytest/issues/2719>_)

• Internal refactor: simplify ascii string escaping by using the
  backslashreplace error handler in newer Python 3 versions. (2734 <https://github.com/pytest-dev/pytest/issues/2734>_)

• Remove unnecessary mark evaluator in unittest plugin (2767 <https://github.com/pytest-dev/pytest/issues/2767>_)

• Calls to Metafunc.addcall now emit a deprecation warning. This function
  is scheduled to be removed in pytest-4.0. (2876 <https://github.com/pytest-dev/pytest/issues/2876>_)

• Internal move of the parameterset extraction to a more maintainable place.
  (2877 <https://github.com/pytest-dev/pytest/issues/2877>_)

• Internal refactoring to simplify scope node lookup. (2910 <https://github.com/pytest-dev/pytest/issues/2910>_)

• Configure pytest to prevent pip from installing pytest in unsupported
  Python versions. (2922 <https://github.com/pytest-dev/pytest/issues/2922>_)

3.2.5

=========================

Bug Fixes

• Remove py<1.5 restriction from pytest as this can cause version
  conflicts in some installations. (2926 <https://github.com/pytest-dev/pytest/issues/2926>_)

3.2.4

=========================

Bug Fixes

• Fix the bug where running with --pyargs will result in items with
  empty parent.nodeid if run from a different root directory. (2775 <https://github.com/pytest-dev/pytest/issues/2775>_)

• Fix issue with pytest.parametrize if argnames was specified as keyword arguments.
  (2819 <https://github.com/pytest-dev/pytest/issues/2819>_)

• Strip whitespace from marker names when reading them from INI config. (2856 <https://github.com/pytest-dev/pytest/issues/2856>_)

• Show full context of doctest source in the pytest output, if the line number of
  failed example in the docstring is < 9. (2882 <https://github.com/pytest-dev/pytest/issues/2882>_)

• Match fixture paths against actual path segments in order to avoid matching folders which share a prefix.
  (2836 <https://github.com/pytest-dev/pytest/issues/2836>_)

Improved Documentation

• Introduce a dedicated section about conftest.py. (1505 <https://github.com/pytest-dev/pytest/issues/1505>_)

• Explicitly mention xpass in the documentation of xfail. (1997 <https://github.com/pytest-dev/pytest/issues/1997>_)

• Append example for pytest.param in the example/parametrize document. (2658 <https://github.com/pytest-dev/pytest/issues/2658>_)

• List python 3.6 in the documented supported versions in the getting started
  document. (2903 <https://github.com/pytest-dev/pytest/issues/2903>_)

• Clarify the documentation of available fixture scopes. (538 <https://github.com/pytest-dev/pytest/issues/538>_)

• Add documentation about the python -m pytest invocation adding the
  current directory to sys.path. (911 <https://github.com/pytest-dev/pytest/issues/911>_)

selenium 3.7.0 -> 3.8.0
