Flask Changelog |
|
=============== |
|
|
|
Here you can see the full list of changes between each Flask release. |
|
|
|
Version 0.9 |
|
----------- |
|
|
|
Relase date to be decided, codename to be chosen. |
|
|
|
- The :func:`flask.url_for` function now can generate anchors to the |
|
generated links. |
|
|
|
Version 0.8.1 |
|
------------- |
|
|
|
Bugfix release, release date to be decided |
|
|
|
- Fixed an issue with the undocumented `flask.session` module to not |
|
work properly on Python 2.5. It should not be used but did cause |
|
some problems for package managers. |
|
|
|
Version 0.8 |
|
----------- |
|
|
|
Released on September 29th 2011, codename Rakija |
|
|
|
- Refactored session support into a session interface so that |
|
the implementation of the sessions can be changed without |
|
having to override the Flask class. |
|
- Empty session cookies are now deleted properly automatically. |
|
- View functions can now opt out of getting the automatic |
|
OPTIONS implementation. |
|
- HTTP exceptions and Bad Request errors can now be trapped so that they |
|
show up normally in the traceback. |
|
- Flask in debug mode is now detecting some common problems and tries to |
|
warn you about them. |
|
- Flask in debug mode will now complain with an assertion error if a view |
|
was attached after the first request was handled. This gives earlier |
|
feedback when users forget to import view code ahead of time. |
|
- Added the ability to register callbacks that are only triggered once at |
|
the beginning of the first request. (:meth:`Flask.before_first_request`) |
|
- Malformed JSON data will now trigger a bad request HTTP exception instead |
|
of a value error which usually would result in a 500 internal server |
|
error if not handled. This is a backwards incompatible change. |
|
- Applications now not only have a root path where the resources and modules |
|
are located but also an instane path which is the designated place to |
|
drop files that are modified at runtime (uploads etc.). Also this is |
|
conceptionally only instance depending and outside version control so it's |
|
the perfect place to put configuration files etc. For more information |
|
see :ref:`instance-folders`. |
|
- Added the ``APPLICATION_ROOT`` configuration variable. |
|
- Implemented :meth:`~flask.testing.TestClient.session_transaction` to |
|
easily modify sessions from the test environment. |
|
- Refactored test client internally. The ``APPLICATION_ROOT`` configuration |
|
variable as well as ``SERVER_NAME`` are now properly used by the test client |
|
as defaults. |
|
- Added :attr:`flask.views.View.decorators` to support simpler decorating of |
|
pluggable (class based) views. |
|
- Fixed an issue where the test client if used with the with statement did not |
|
trigger the execution of the teardown handlers. |
|
- Added finer control over the session cookie parameters. |
|
- HEAD requests to a method view now automatically dispatch to the `get` |
|
method if no handler was implemented. |
|
- Implemented the virtual :mod:`flask.ext` package to import extensions from. |
|
- The context preservation on exceptions is now an integral component of |
|
Flask itself and no longer of the test client. This cleaned up some |
|
internal logic and lowers the odds of runaway request contexts in unittests. |
|
|
|
Version 0.7.3 |
|
------------- |
|
|
|
Bugfix release, release date to be decided |
|
|
|
- Fixed the Jinja2 environment's list_templates method not returning the |
|
correct names when blueprints or modules were involved. |
|
|
|
Version 0.7.2 |
|
------------- |
|
|
|
Bugfix release, released on July 6th 2011 |
|
|
|
- Fixed an issue with URL processors not properly working on |
|
blueprints. |
|
|
|
Version 0.7.1 |
|
------------- |
|
|
|
Bugfix release, released on June 29th 2011 |
|
|
|
- Added missing future import that broke 2.5 compatibility. |
|
- Fixed an infinite redirect issue with blueprints. |
|
|
|
Version 0.7 |
|
----------- |
|
|
|
Released on June 28th 2011, codename Grappa |
|
|
|
- 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`. |
|
- Flask no longer internally depends on rules being added through the |
|
`add_url_rule` function and can now also accept regular werkzeug |
|
rules added to the url map. |
|
- Added an `endpoint` method to the flask application object which |
|
allows one to register a callback to an arbitrary endpoint with |
|
a decorator. |
|
- Use Last-Modified for static file sending instead of Date which |
|
was incorrectly introduced in 0.6. |
|
- Added `create_jinja_loader` to override the loader creation process. |
|
- Implemented a silent flag for `config.from_pyfile`. |
|
- Added `teardown_request` decorator, for functions that should run at the end |
|
of a request regardless of whether an exception occurred. Also the behavior |
|
for `after_request` was changed. It's now no longer executed when an exception |
|
is raised. See :ref:`upgrading-to-new-teardown-handling` |
|
- Implemented :func:`flask.has_request_context` |
|
- Deprecated `init_jinja_globals`. Override the |
|
:meth:`~flask.Flask.create_jinja_environment` method instead to |
|
achieve the same functionality. |
|
- Added :func:`flask.safe_join` |
|
- The automatic JSON request data unpacking now looks at the charset |
|
mimetype parameter. |
|
- Don't modify the session on :func:`flask.get_flashed_messages` if there |
|
are no messages in the session. |
|
- `before_request` handlers are now able to abort requests with errors. |
|
- it is not possible to define user exception handlers. That way you can |
|
provide custom error messages from a central hub for certain errors that |
|
might occur during request processing (for instance database connection |
|
errors, timeouts from remote resources etc.). |
|
- Blueprints can provide blueprint specific error handlers. |
|
- Implemented generic :ref:`views` (class based views). |
|
|
|
Version 0.6.1 |
|
------------- |
|
|
|
Bugfix release, released on December 31st 2010 |
|
|
|
- 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. |
|
- Fixed a security problem that allowed clients to download arbitrary files |
|
if the host server was a windows based operating system and the client |
|
uses backslashes to escape the directory the files where exposed from. |
|
|
|
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. |
|
|
|
Version 0.2 |
|
----------- |
|
|
|
Released on May 12th 2010, codename Jägermeister |
|
|
|
- various bugfixes |
|
- integrated JSON support |
|
- added :func:`~flask.get_template_attribute` helper function. |
|
- :meth:`~flask.Flask.add_url_rule` can now also register a |
|
view function. |
|
- refactored internal request dispatching. |
|
- server listens on 127.0.0.1 by default now to fix issues with chrome. |
|
- added external URL support. |
|
- added support for :func:`~flask.send_file` |
|
- module support and internal request handling refactoring |
|
to better support pluggable applications. |
|
- sessions can be set to be permanent now on a per-session basis. |
|
- better error reporting on missing secret keys. |
|
- added support for Google Appengine. |
|
|
|
