Following issues/PRs were fixed for this release:

Bug Fixes

* #310: Rework API documentation. Follow a more “semi-manual” attempt
  and add auto directives into docs/api.rst.

Improved Documentation

* #312: Rework “Usage” section.
  * Mention the rename of VersionInfo to Version class
  * Remove `semver.` prefix in doctests to make examples shorter
  * Correct some references to dunder methods like `__getitem__()`,
    `__gt__()` etc.
  * Remove inconsistencies and mention module level function as
    deprecated and discouraged from using
  * Make empty `super()` call in `semverwithvprefix.py` example

* #315: Improve release procedure text

* #337: Improve documentation for semver max/min

Trivial/Internal Changes

* #309: Some (private) functions from the semver.version module has been changed.
  The following functions got renamed as it is only useful inside the
  Version class:

  * function `semver.version.comparator` got renamed to
    `semver.version._comparator()`
  * function `semver.version.cmp` got renamed to `semver.version._cmp()`

  The following functions got integrated into the Version class:

   * function `semver.version._nat_cmd` as a classmethod
   * function `semver.version.ensure_str`

* #313: Correct `tox.ini` for changelog entry to skip installation for
  semver. This should speed up the execution of towncrier.

* #316: Comparisons of Version class and other types return now a
  `NotImplemented` constant instead of a `TypeError` exception.

  The `NotImplemented` section of the Python documentation recommends
  returning this constant when comparing with `__gt__`, `__lt__`, and
  other comparison operators to “to indicate that the operation is not
  implemented with respect to the other type”.

* #319: Introduce stages in `.travis.yml`. The config file contains now
  two stages: check and test. If check fails, the test stage won’t be
  executed. This could speed up things when some checks fails.

* #322: Switch from Travis CI to GitHub Actions.

* #347: Support Python 3.10 in GitHub Action and other config files.

* Start supporting Python 3.10
