Changelog
=========

This is a record of changes made between each Mutalyzer release.


Version 2.0.0
-------------

Released on September 26th 2014.

This release does not bring many new features, but comes with significant
changes to the technical infrastructure. `Merge request #6
<https://git.lumc.nl/mutalyzer/mutalyzer/merge_requests/6>`_ tracks most of
this.

Some highlights especially users of the webservices should be aware of:

- HTTP/RPC+JSON webservice has changed response format (wrapper object
  removed). See below for an :ref:`example <changelog_200_example>`.
- No more plain HTTP access, only redirects to HTTPS.
- Many website entrypoints have changed URLs and form parameter names (the old
  ones have HTTP redirects).
- Removed old redirects from paths starting with ``/2.0/``.
- In maintenance mode, all requests get a *Service Temporarily Unavailable*
  response with status code 503.

Other changes:

- Upload a genbank file using the SOAP webservice (`uploadGenBankLocalFile`).
- Do not cleanup the cache during request handling (`#18
  <https://git.lumc.nl/mutalyzer/mutalyzer/issues/18>`_).
- Add GRCh38 (hg38) assembly (`#20
  <https://git.lumc.nl/mutalyzer/mutalyzer/merge_requests/20>`_).
- Move from nose to `pytest <http://pytest.org/>`_ for unit tests (`#23
  <https://git.lumc.nl/mutalyzer/mutalyzer/merge_requests/23>`_).
- Fix running Mutalyzer in a `virtual environment
  <http://virtualenv.readthedocs.org/>`_ and have an up-to-date
  ``requirements.txt`` for `pip <http://pip.readthedocs.org/>`_ (`#4
  <https://git.lumc.nl/mutalyzer/mutalyzer/merge_requests/4>`_).
- Switch from TAL to Jinja2 (`#3
  <https://git.lumc.nl/mutalyzer/mutalyzer/merge_requests/3>`_).
- Refactor user interfaces (`#5
  <https://git.lumc.nl/mutalyzer/mutalyzer/merge_requests/5>`_).
- Move from configobj to Python module based config (`#7
  <https://git.lumc.nl/mutalyzer/mutalyzer/merge_requests/7>`_).
- Use SQLAlchemy as ORM (`#8
  <https://git.lumc.nl/mutalyzer/mutalyzer/merge_requests/8>`_).
- Use Redis for stat counters (`#10
  <https://git.lumc.nl/mutalyzer/mutalyzer/merge_requests/10>`_).
- Port website from web.py to Flask (`#11
  <https://git.lumc.nl/mutalyzer/mutalyzer/merge_requests/11>`_).
- Isolated unit tests using fixtures and an in-memory database (`#12
  <https://git.lumc.nl/mutalyzer/mutalyzer/merge_requests/12>`_).
- Display announcement on website (`#14
  <https://git.lumc.nl/mutalyzer/mutalyzer/merge_requests/14>`_).
- Database migrations with Alembic (`#15
  <https://git.lumc.nl/mutalyzer/mutalyzer/merge_requests/15>`_).
- Update documentation and use Sphinx (`#16
  <https://git.lumc.nl/mutalyzer/mutalyzer/merge_requests/16>`_).
- Move to `semantic versioning <http://semver.org/>`_, starting with version
  2.0.0 (`#22 <https://git.lumc.nl/mutalyzer/mutalyzer/merge_requests/22>`_).
- Add 404 not found page.
- Don't auto remove comma characters in syntax checker.
- Add a dash (``-``) as an allowed character in the gene name.
- Range, reverse complement range, and compound
  insertions/insertion-deletions.

.. _changelog_200_example:

The wrapper object has been removed from the HTTP/RPC+JSON webservice response
format. As an example, consider an old response format for the `checkSyntax`
method:

.. code-block:: json

    {
      "checkSyntaxResponse": {
        "checkSyntaxResult": {
          "valid": true,
          "messages": {
            "SoapMessage": []
          }
        }
      }
    }

The new response format is:

.. code-block:: json

    {
      "valid": true,
      "messages": []
    }

Older versions
--------------

The first lines of code for Mutalyzer 2.0 where written July 28th 2009, and
version 2.0.beta-8 was released on January 31st 2011. As far as Mutalyzer 1 is
concerned, archaeology is not really our field of research.
