Added

• Add support for Python 3.12.
• Add Present and Absent for absence checks in assert_json_subset().

Removed

• Drop support for Python 3.7.

Deprecated

• Deprecate Exists in favor of Present and Absent in
  assert_json_subset().

Incompatible Changes

• Drop support for Python 3.6.

API Additions

• Add assert_not_regex().

Other Changes

• Modernize the type stubs.

API Additions

• assert_json_subset() can now check for the existence or non-existence
  of object members using the new Exists helper.
• Non-string (or Exists) object member names in the first argument to
  assert_json_subset() now raise a TypeError.

API-Incompatible Changes

• Drop support for Python 2.7 and 3.5.

API-Incompatible Changes

• Drop support for Python 3.4.

API Additions

• AssertRaisesContext and AssertWarnsContext now return themselves
  when __enter__() is called. By extension it now easier to call
  add_test() with assert_raises() et al:

with assert_raises(KeyError) as context:
    context.add_test(...)
    ...

• Add AssertRaisesContext.exc_val property to access the caught
  exception after leaving the context manager:

with assert_raises(KeyError) as context:
    ...
assert_equal("expected message", str(context.exc_val))

Improvements

• AssertRaisesContext and sub-classes are now generic over the
  exception type.

API Additions

• Add assert_json_subset().

Improvements

• Add support for Python 3.7 (contributed by Frank Niessink).

API Additions

• Add assert_dict_equal().
• Add assert_dict_superset().

Improvements

• assert_equal(): Use assert_dict_equal() if applicable.

Improvements

• fail() is now marked with NoReturn in type stub.

Bug Fixes

• Improve type annotations for Python 2.

• Fix type signature of AssertRaisesContext.__exit__().

Improvements

• Add a py.typed file to signal that this package supports type hints.

Bug Fixes

• assert_raises_regex(): Handle exceptions without any message correctly.

API-Incompatible Changes

• Replace msg argument with msg_fmt in all assertions (except fail()).
  This allows you to customize error messages more easily than before, because
  format() with appropriate keyword arguments is now called on these
  strings. See the documentation of individual assertions for the supported
  arguments.
• Replace AssertRaisesContext.msg and AssertWarnsContext.msg with msg_fmt.
• assert_almost_equal(), assert_not_almost_equal(): Place msg_fmt as third
  argument.

API Additions

• assert_count_equal(): Add msg_fmt argument.
• Add AssertRaisesErrnoContext, AssertRaisesRegexContext, and
  AssertWarnsRegexContext.

API Additions

• Add assert_not_almost_equal().

Improvements

• assert_almost_equal(): Raise ValueError if diff <= 0.

Bug Fixes

• assert_almost_equal() would never fail if a delta was supplied and the
  second number was smaller than the first.
• Use fail() instead of raise AssertionError in a few assertions.

API Additions

• Add assert_warns() and assert_warns_regex().

Distribute as wheel.

• Add a stub file.
• Add assert_count_equal().

Add assert_less(), assert_less_equal(), assert_greater(), assert_greater_equal(), assert_not_is_instance().

First public release of the asserts package. This release still misses some assertions that are in the latest unittest module. Also, assert_equal does not support rich comparison support, yet.
