Version 3.0.3

Bug Fixes

* :pr:`453`: The check in ``_comparator`` does not match the check in \ 
:meth:`Version.compare`.
  This breaks comparision with subclasses.

Improved Documentation

* :pr:`435`: Several small improvements for documentation:

  * Add meta description to improve SEO
  * Use canonicals on ReadTheDocs (commit 87f639f)
  * Pin versions for reproducable doc builds (commit 03fb990)
  * Add missing :file:`.readthedocs.yaml` file (commit ec9348a)
  * Correct some smaller issues when building (commit f65feab)

* :pr:`436`: Move search box more at the top. This makes it easier for
  users as if the TOC is long, the search box isn't visible
  anymore.

Features

* :pr:`439`: Improve type hints to fix TODOs
