Release Notes
=============
Djrill practices `semantic versioning <semver>`_.
Among other things, this means that minor updates
(1.x to 1.y) should always be backwards-compatible,
and breaking changes will always increment the
major version number (1.x to 2.0).
Djrill 2.0 (in development)
---------------------------
Djrill 2.0 is under development and includes some breaking changes.
Although the changes won't impact most Djrill users, the previous
version of Djrill (1.4) tries to warn you if you use things
that will change. (Warnings appear in the console when running Django
in debug mode.)
Breaking Changes in Djrill 2.0
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Dropped support for Django 1.3, Python 2.6, and Python 3.2
Although Djrill may still work with these older configurations,
we no longer test against them. Djrill now requires Django 1.4
or later and Python 2.7, 3.3, or 3.4.
If you require earlier support, Djrill 1.4 remains available.
Removed DjrillAdminSite
Earlier versions of Djrill included a custom Django admin site.
The equivalent functionality is available in Mandrill's dashboard.
You should remove any references to DjrillAdminSite from your
:file:`urls.py`. E.g.::
.. code-block:: python
# Remove these:
from djrill import DjrillAdminSite
admin.site = DjrillAdminSite()
Also, on Django 1.7 or later if you had switched your :setting:`INSTALLED_APPS`
(in :file:`settings.py`) to use ``'django.contrib.admin.apps.SimpleAdminConfig'``
you *may* want to switch back to the default ``'django.contrib.admin'``
and remove the call to ``admin.autodiscover()`` in your :file:`urls.py`.
(Do this only if you changed to SimpleAdminConfig for Djrill, and aren't
creating custom admin sites for any other Django apps you use.)
**Dates in merge data and other attributes**
Djrill automatically converts :attr:`send_at` date and datetime
values to the ISO 8601 string format expected by the Mandrill API.
Unintentionally, it also converts dates used in other Mandrill message
attributes (such as :attr:`merge_vars` or :attr:`metadata`) where it
might not be expected (or appropriate).
Djrill 2.0 will remove this automatic date formatting, except
for attributes that are inherently dates (currently only `send_at`).
To assist in detecting code relying on the (undocumented) current
behavior, Djrill 1.4 will report a DeprecationWarning for date
or datetime values used in any Mandrill message attributes other
than `send_at`. See :ref:`formatting-merge-data` for other options.
**DjrillMessage class**
The ``DjrillMessage`` class has not been needed since Djrill 0.2.
You can simply set Djrill message attributes on any Django
:class:`~django.core.mail.EmailMessage` object.
Djrill 1.4 will report a DeprecationWarning if you are still
using DjrillMessage.
**DjrillBackendHTTPError**
The ``DjrillBackendHTTPError`` exception was replaced in Djrill 0.3
with :exc:`djrill.MandrillAPIError`. Djrill 1.4 will report a
DeprecationWarning if you are still importing DjrillBackendHTTPError.
Older Releases
--------------
Version 1.4:
* Django 1.8 support
* Support new Django 1.8 EmailMessage reply_to param.
(Specifying a :ref:`Reply-To header <message-headers>`
still works, with any version of Django,
and will override the reply_to param if you use both.)
* Include Mandrill error response in str(MandrillAPIError),
to make errors easier to understand.
* More-helpful exception when using a non-JSON-serializable
type in merge_vars and other Djrill message attributes
* Deprecation warnings for upcoming 2.0 changes (see above)
Version 1.3:
* Use Mandrill secure https API endpoint (rather than http).
* Support :attr:`merge_language` option (for choosing between
Handlebars and Mailchimp templates).
Version 1.2:
* Support Django 1.7; add testing on Python 3.3, 3.4, and PyPy
* Bug fixes
Version 1.1:
* Allow use of Mandrill template default "from" and "subject" fields,
via :attr:`use_template_from` and :attr:`use_template_subject`.
* Fix `UnicodeEncodeError` with unicode attachments
Version 1.0:
* Global :setting:`MANDRILL_SUBACCOUNT` setting
Version 0.9:
* Better handling for "cc" and "bcc" recipients.
* Allow all extra message headers in send.
(Mandrill has relaxed previous API restrictions on headers.)
Version 0.8:
* Expose :ref:`mandrill-response` on sent messages
Version 0.7:
* Support for Mandrill send options :attr:`async`, :attr:`important`,
:attr:`ip_pool`, :attr:`return_path_domain`, :attr:`send_at`,
:attr:`subaccount`, and :attr:`view_content_link`
Version 0.6:
* Support for signed webhooks
Version 0.5:
* Support for incoming mail and other Mandrill webhooks
* Support for Mandrill send options :attr:`auto_html`, :attr:`tracking_domain`
and :attr:`signing_domain`.
Version 0.4:
* Attachments with a Content-ID are now treated as
:ref:`embedded images <sending-attachments>`
* New Mandrill :attr:`inline_css` option is supported
* Remove limitations on attachment types, to track Mandrill change
* Documentation is now available on
`djrill.readthedocs.org <https://djrill.readthedocs.org>`_
Version 0.3:
* :ref:`Attachments <sending-attachments>` are now supported
* :ref:`Mandrill templates <mandrill-templates>` are now supported
* A bcc address is now passed to Mandrill as bcc, rather than being lumped in
with the "to" recipients. Multiple bcc recipients will now raise an exception,
as Mandrill only allows one.
* Python 3 support (with Django 1.5)
* Exceptions should be more useful:
:exc:`djrill.NotSupportedByMandrillError` replaces generic ValueError;
:exc:`djrill.MandrillAPIError` replaces DjrillBackendHTTPError, and is now
derived from requests.HTTPError.
(New exceptions are backwards compatible with old ones for existing code.)
Version 0.2:
* ``MANDRILL_API_URL`` is no longer required in settings.py
* Earlier versions of Djrill required use of a ``DjrillMessage`` class to
specify Mandrill-specific options. This is no longer needed -- Mandrill
options can now be set directly on a Django ``EmailMessage`` object or any
subclass. (Existing code can continue to use ``DjrillMessage``.)
