Version 0.1

First public preview release.

Released on May 12th 2010, codename Jägermeister

various bugfixes
integrated JSON support
added get_template_attribute() helper function.
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 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.

Released on May 28th 2010, codename Schnaps

added support for categories for flashed messages.
the application now configures a 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.

Bugfix release, released on May 28th 2010

fixed a error reporting bug with 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)

Released on June 18th 2010, codename Rakia

added the ability to register application wide error handlers from modules.
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.

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autoescaping is no longer active for all templates.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 behavior can be changed with the autoescape tag.
refactored Flask internally. It now consists of more than a single file.
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 behavior.
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.

Bugfix Release, released on July 15th 2010

fixed another issue with loading templates from directories when modules were used.

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 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 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 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 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.
