Release 4.11 is out

[Chenxiong Qi]

Hi all,

I'm pleased to announce a new release 4.11 is available now.

Highlights
==========

Bugfixes
--------

* Code sending mail notification on specific event are fixed so that they can
  be scheduled as Celery tasks (`PR#904`_). To try the asynchronous tasks, run
  ``podman-compose up`` from the top directory of source code.

Distribution
------------

* RPM subpackages are built for the extras including ``mysql``, ``pgsql``,
  ``krbauth``, ``bugzilla`` and ``async``. It is possible to choose the
  required package to install according to specific requirements. (`#882`_)

Infrastructure improvements
---------------------------

* Fedora 34 is added to CI workflow to test the package build. (`#909`_)

* Tests run in Python 3.9 with various database engines in tests environment.
  (`#912`_)

* RabbitMQ is added to the ``docker-compose.yml`` as a messaging broker and it
  works to run asynchronous tasks. (`PR#904`_)

.. _PR#904: https://github.com/Nitrate/Nitrate/pull/904

Get Nitrate
===========

From PyPI
---------

.. code-block:: shell

   python3 -m pip install nitrate-tcms

RPM Packages
------------

Packages are available via a `Fedora Copr`_.

.. code-block:: shell

   sudo dnf copr enable cqi/python-nitrate-tcms
   sudo dnf install python-nitrate-tcms

   # Install extra subpackages accordingly, e.g.
   sudo dnf install python-nitrate-tcms+pgsql python-nitrate-tcms+async

.. _Fedora Copr:
https://copr.fedorainfracloud.org/coprs/cqi/python-nitrate-tcms/

Container Images
----------------

* ``quay.io/nitrate/nitrate:4.11``: the main image including Nitrate Web
  application.

* ``quay.io/nitrate/nitrate-worker:4.11``: an optional worker image if the
  asynchronous tasks scheduled and run by Celery are required.

Refer to :ref:`deployment` for detailed information.

Database Migration

* Many help text of ``issuetracker`` app are updated, which cause a database
  migration is generated.
