ChangeLog
=========

2.10.1 (unreleased)
-------------------

*Minor:*

    * `112 <https://github.com/rbarrois/python-semanticversion/issues/112>`_:
      Functions returning a new ``Version`` instance reuse the current class,
      helping with subclassing.

*Bugfix:*

    * `141 <https://github.com/rbarrois/python-semanticversion/issues/141>`_:
      Ensure we return a new instance for ``Version.truncate("build")``.


2.10.0 (2022-05-26)
-------------------

*New:*

    * `132 <https://github.com/rbarrois/python-semanticversion/issues/132>`_:
      Ensure sorting a collection of versions is always stable, even with
      build metadata.


2.9.0 (2022-02-06)
------------------

*New:*

    * Add support for Django 3.1, 3.2, 4.0
    * Add support for Python 3.7 / 3.8 / 3.9 / 3.10


2.8.5 (2020-04-29)
------------------

*Bugfix:*

    * `98 <https://github.com/rbarrois/python-semanticversion/issues/98>`_:

2.8.4 (2019-12-21)
------------------

*Bugfix:*

    * `#89 <https://github.com/rbarrois/python-semanticversion/issues/89>`_:
      Properly coerce versions with leading zeroes in components (e.g.
      ``1.01.007``)


2.8.3 (2019-11-21)
------------------

*New:*
    - Add `Clause.prettyprint()` for debugging

*Bugfix:*

    * `#86 <https://github.com/rbarrois/python-semanticversion/issues/86>`_:
      Fix handling of prerelease ranges within `NpmSpec`


2.8.2 (2019-09-06)
------------------

*Bugfix:*

    * `#82 <https://github.com/rbarrois/python-semanticversion/issues/82>`_:
      Restore computation of ``Spec.specs`` for single-term expressions
      (``>=0.1.2``)


2.8.1 (2019-08-29)
------------------

*Bugfix:*

    * Restored attribute ``Spec.specs``, removed by mistake during the refactor.


2.8.0 (2019-08-29)

2.7.1 (2019-08-28)
------------------

*Bugfix:*

    * Fix parsing of npm-based caret expressions.


2.7.0 (2019-08-28)
------------------

This release brings a couple of significant changes:

- Allow to define several range description syntaxes (``SimpleSpec``, ``NpmSpec``, ...)
- Fix bugs and unexpected behaviours in the ``SimpleSpec`` implementation.

Backwards compatibility has been kept, but users should adjust their code for the new features:

- Use ``SimpleSpec`` instead of ``Spec``
- Replace calls to ``Version('1.2', partial=True)`` with ``SimpleSpec('~1.2')``
- ``iter(some_spec)`` is deprecated.

*New:*

    * Allow creation of a ``Version`` directly from parsed components, as keyword arguments
      (``Version(major=1, minor=2, patch=3)``)
    * Add ``Version.truncate()`` to build a truncated copy of a ``Version``
    * Add ``NpmSpec(...)``, following strict NPM matching rules (https://github.com/npm/node-semver#ranges)
    * Add ``Spec.parse('xxx', syntax='<syntax>')`` for simpler multi-syntax support
    * Add ``Version().precedence_key``, for use in ``sort(versions, key=lambda v: v.precedence_key)`` calls.
      The contents of this attribute is an implementation detail.

*Bugfix:*

    * Fix inconsistent behaviour regarding versions with a prerelease specification.

*Deprecated:*

    * Deprecate the ``Spec`` class (Removed in 3.1); use the ``SimpleSpec`` class instead
    * Deprecate the internal ``SpecItem`` class (Removed in 3.0).
    * Deprecate the ``partial=True`` form of ``Version``; use ``SimpleSpec`` instead.

*Removed:*

    * Remove support for Python2 (End of life 4 months after this release)

*Refactor:*

    * Switch spec computation to a two-step process: convert the spec to a combination
      of simple comparisons with clear semantics, then use those.


2.6.0 (2016-09-25)
------------------

*New:*

    * `#43 <https://github.com/rbarrois/python-semanticversion/issues/43>`_:
      Add support for Django up to 1.10.

*Removed:*

    * Remove support for Django<1.7

*Bugfix:*

    * `#35 <https://github.com/rbarrois/python-semanticversion/issues/35>`_:
      Properly handle `^0.X.Y` in a NPM-compatible way

2.5.0 (2016-02-12)
------------------

*Bugfix:*

    `#18 <https://github.com/rbarrois/python-semanticversion/issues/18>`_: According to SemVer 2.0.0, build numbers aren't ordered.

    * Remove specs of the ``Spec('<1.1.3+')`` form
    * Comparing ``Version('0.1.0')`` to ``Version('0.1.0+bcd')`` has new
      rules::

          >>> Version('0.1.0+1') == Version('0.1.0+bcd')
          False
          >>> Version('0.1.0+1') != Version('0.1.0+bcd')
          True
          >>> Version('0.1.0+1') < Version('0.1.0+bcd')
          False
          >>> Version('0.1.0+1') > Version('0.1.0+bcd')
          False
          >>> Version('0.1.0+1') <= Version('0.1.0+bcd')
          False
          >>> Version('0.1.0+1') >= Version('0.1.0+bcd')
          False
          >>> compare(Version('0.1.0+1'), Version('0.1.0+bcd'))
          NotImplemented

    * :func:`semantic_version.compare` returns ``NotImplemented`` when its
      parameters differ only by build metadata
    * ``Spec('<=1.3.0')`` now matches ``Version('1.3.0+abde24fe883')``

    * `#24 <https://github.com/rbarrois/python-semanticversion/issues/24>`_: Fix handling of bumping pre-release versions, thanks to @minchinweb.
    * `#30 <https://github.com/rbarrois/python-semanticversion/issues/30>`_: Add support for NPM-style ``^1.2.3`` and ``~2.3.4`` specs, thanks to @skwashd
