Flask Changelog
|
|
|
|
===============
|
|
|
|
|
|
|
|
Here you can see the full list of changes between each Flask release.
|
|
|
|
|
|
|
|
Version 0.7
|
|
|
|
-----------
|
|
|
|
|
|
|
|
Release date to be announced, codename to be selected
|
|
|
|
|
|
|
|
- Added :meth:`~flask.Flask.make_default_options_response`
|
|
|
|
which can be used by subclasses to alter the default
|
|
|
|
behaviour for `OPTIONS` responses.
|
|
|
|
- Unbound locals now raise a proper :exc:`RuntimeError` instead
|
|
|
|
of an :exc:`AttributeError`.
|
|
|
|
- Mimetype guessing and etag support based on file objects is now
|
|
|
|
deprecated for :func:`flask.send_file` because it was unreliable.
|
|
|
|
Pass filenames instead or attach your own etags and provide a
|
|
|
|
proper mimetype by hand.
|
|
|
|
- Static file handling for modules now requires the name of the
|
|
|
|
static folder to be supplied explicitly. The previous autodetection
|
|
|
|
was not reliable and caused issues on Google's App Engine. Until
|
|
|
|
1.0 the old behaviour will continue to work but issue dependency
|
|
|
|
warnings.
|
|
|
|
- fixed a problem for Flask to run on jython.
|
|
|
|
- added a `PROPAGATE_EXCEPTIONS` configuration variable that can be
|
|
|
|
used to flip the setting of exception propagation which previously
|
|
|
|
was linked to `DEBUG` alone and is now linked to either `DEBUG` or
|
|
|
|
`TESTING`.
|
|
|
|
|
|
|
|
Version 0.6.1
|
|
|
|
-------------
|
|
|
|
|
|
|
|
Bugfix release, release date to be announced.
|
|
|
|
|
|
|
|
- Fixed an issue where the default `OPTIONS` response was
|
|
|
|
not exposing all valid methods in the `Allow` header.
|
|
|
|
- Jinja2 template loading syntax now allows "./" in front of
|
|
|
|
a template load path. Previously this caused issues with
|
|
|
|
module setups.
|
|
|
|
- Fixed an issue where the subdomain setting for modules was
|
|
|
|
ignored for the static folder.
|
|
|
|
|
|
|
|
Version 0.6
|
|
|
|
-----------
|
|
|
|
|
|
|
|
Released on July 27th 2010, codename Whisky
|
|
|
|
|
|
|
|
- after request functions are now called in reverse order of
|
|
|
|
registration.
|
|
|
|
- OPTIONS is now automatically implemented by Flask unless the
|
|
|
|
application explicitly adds 'OPTIONS' as method to the URL rule.
|
|
|
|
In this case no automatic OPTIONS handling kicks in.
|
|
|
|
- static rules are now even in place if there is no static folder
|
|
|
|
for the module. This was implemented to aid GAE which will
|
|
|
|
remove the static folder if it's part of a mapping in the .yml
|
|
|
|
file.
|
|
|
|
- the :attr:`~flask.Flask.config` is now available in the templates
|
|
|
|
as `config`.
|
|
|
|
- context processors will no longer override values passed directly
|
|
|
|
to the render function.
|
|
|
|
- added the ability to limit the incoming request data with the
|
|
|
|
new ``MAX_CONTENT_LENGTH`` configuration value.
|
|
|
|
- the endpoint for the :meth:`flask.Module.add_url_rule` method
|
|
|
|
is now optional to be consistent with the function of the
|
|
|
|
same name on the application object.
|
|
|
|
- added a :func:`flask.make_response` function that simplifies
|
|
|
|
creating response object instances in views.
|
|
|
|
- added signalling support based on blinker. This feature is currently
|
|
|
|
optional and supposed to be used by extensions and applications. If
|
|
|
|
you want to use it, make sure to have `blinker`_ installed.
|
|
|
|
- refactored the way URL adapters are created. This process is now
|
|
|
|
fully customizable with the :meth:`~flask.Flask.create_url_adapter`
|
|
|
|
method.
|
|
|
|
- modules can now register for a subdomain instead of just an URL
|
|
|
|
prefix. This makes it possible to bind a whole module to a
|
|
|
|
configurable subdomain.

Version 0.5.2
|
|
|
|
-------------
|
|
|
|
|
|
|
|
Bugfix Release, released on July 15th 2010
|
|
|
|
|
|
|
|
- fixed another issue with loading templates from directories when
|
|
|
|
modules were used.
|
|
|
|
|
|
|
|
Version 0.5.1
|
|
|
|
-------------
|
|
|
|
|
|
|
|
Bugfix Release, released on July 6th 2010
|
|
|
|
|
|
|
|
- fixes an issue with template loading from directories when modules
|
|
|
|
where used.
|
|
|
|
|
|
|
|
Version 0.5
|
|
|
|
-----------
|
|
|
|
|
|
|
|
Released on July 6th 2010, codename Calvados
|
|
|
|
|
|
|
|
- fixed a bug with subdomains that was caused by the inability to
|
|
|
|
specify the server name. The server name can now be set with
|
|
|
|
the `SERVER_NAME` config key. This key is now also used to set
|
|
|
|
the session cookie cross-subdomain wide.
|
|
|
|
- autoescaping is no longer active for all templates. Instead it
|
|
|
|
is only active for ``.html``, ``.htm``, ``.xml`` and ``.xhtml``.
|
|
|
|
Inside templates this behaviour can be changed with the
|
|
|
|
``autoescape`` tag.
|
|
|
|
- refactored Flask internally. It now consists of more than a
|
|
|
|
single file.
|
|
|
|
- :func:`flask.send_file` now emits etags and has the ability to
|
|
|
|
do conditional responses builtin.
|
|
|
|
- (temporarily) dropped support for zipped applications. This was a
|
|
|
|
rarely used feature and led to some confusing behaviour.
|
|
|
|
- added support for per-package template and static-file directories.
|
|
|
|
- removed support for `create_jinja_loader` which is no longer used
|
|
|
|
in 0.5 due to the improved module support.
|
|
|
|
- added a helper function to expose files from any directory.
|
|
|
|
|
|
|
|
Version 0.4
|
|
|
|
-----------
|
|
|
|
|
|
|
|
Released on June 18th 2010, codename Rakia
|
|
|
|
|
|
|
|
- added the ability to register application wide error handlers
|
|
|
|
from modules.
|
|
|
|
- :meth:`~flask.Flask.after_request` handlers are now also invoked
|
|
|
|
if the request dies with an exception and an error handling page
|
|
|
|
kicks in.
|
|
|
|
- test client has not the ability to preserve the request context
|
|
|
|
for a little longer. This can also be used to trigger custom
|
|
|
|
requests that do not pop the request stack for testing.
|
|
|
|
- because the Python standard library caches loggers, the name of
|
|
|
|
the logger is configurable now to better support unittests.
|
|
|
|
- added `TESTING` switch that can activate unittesting helpers.
|
|
|
|
- the logger switches to `DEBUG` mode now if debug is enabled.
|
|
|
|
|
|
|
|
Version 0.3.1
|
|
|
|
-------------
|
|
|
|
|
|
|
|
Bugfix release, released on May 28th 2010
|
|
|
|
|
|
|
|
- fixed a error reporting bug with :meth:`flask.Config.from_envvar`
|
|
|
|
- removed some unused code from flask
|
|
|
|
- release does no longer include development leftover files (.git
|
|
|
|
folder for themes, built documentation in zip and pdf file and
|
|
|
|
some .pyc files)
|
|
|
|
|
|
|
|
Version 0.3
|
|
|
|
-----------
|
|
|
|
|
|
|
|
Released on May 28th 2010, codename Schnaps
|
|
|
|
|
|
|
|
- added support for categories for flashed messages.
|
|
|
|
- the application now configures a :class:`logging.Handler` and will
|
|
|
|
log request handling exceptions to that logger when not in debug
|
|
|
|
mode. This makes it possible to receive mails on server errors
|
|
|
|
for example.
|
|
|
|
- added support for context binding that does not require the use of
|
|
|
|
the with statement for playing in the console.
|
|
|
|
- the request context is now available within the with statement making
|
|
|
|
it possible to further push the request context or pop it.
|
|
|
|
- added support for configurations.
|
|
|
|
|
|
