Warning: This is a preview for Bottle-0.12-dev, which is not released yet. Switch to the latest stable release?

# Release Notes and Changelog

## Release 0.11

- Native support for Python 2.x and 3.x syntax. No need to run 2to3 anymore.
- Support for partial downloads (`Range` header) in `static_file()`.
- The new `ResourceManager` interface helps locating files bundled with an application.
- Added a server adapter for waitress.
- New `Bottle.merge()` method to install all routes from one application into another.
- New `BaseRequest.app` property to get the application object that handles a request.
- Added `FormsDict.decode()` to get an all-unicode version (needed by WTForms).
- `MultiDict` and subclasses are now pickle-able.

API Changes

- `Response.status` is a read-write property that can be assigned either a numeric status code or a status string with a reason phrase (`200 OK`). The return value is now a string to better match existing APIs (WebOb, werkzeug). To be absolutely clear, you can use the read-only properties `BaseResponse.status_code` and `BaseResponse.status_line`.

API Deprecations

- `SimpleTALTemplate` is now deprecating. There seems to be no demand.

## Release 0.10

- Plugin API v2
  - To use the new API, set `Plugin.api` to `2`.
  - `Plugin.apply()` receives a `Route` object instead of a context dictionary as second parameter. The new object offers some additional information and may be extended in the future.
  - Plugin names are considered unique now. The topmost plugin with a given name on a given route is installed, all other plugins with the same name are silently ignored.
- The Request/Response Objects
  - Added `BaseRequest.json`, `BaseRequest.remote_route`, `BaseRequest.remote_addr`, `BaseRequest.query` and `BaseRequest.script_name`.
  - Added `BaseResponse.status_line` and `BaseResponse.status_code` attributes. In future releases, `BaseResponse.status` will return a string (e.g. `200 OK`) instead of an integer to match the API of other common frameworks. To make the transition as smooth as possible, you should use the verbose attributes from now on.
  - Replaced `MultiDict` with a specialized `FormsDict` in many places. The new dict implementation allows attribute access and handles unicode form values transparently.
- Templates
  - Added three new functions to the SimpleTemplate default namespace that handle undefined variables: `stpl.defined()`, `stpl.get()` and `stpl.setdefault()`.
  - The default escape function for SimpleTemplate now additionally escapes single and double quotes.
- Routing
  - A new route syntax (e.g. `/object/<id:int>`) and support for route wildcard filters.
  - Four new wildcard filters: int, float, path and re.
- Oher changes
  - Added command line interface to load applications and start servers.
  - Introduced a `ConfigDict` that makes accessing configuration a lot easier (attribute access and auto-expanding namespaces).
  - Added support for raw WSGI applications to `Bottle.mount()`.
  - `Bottle.mount()` parameter order changed.
  - `Bottle.route()` now accpets an import string for the `callback` parameter.
  - Dropped Gunicorn 0.8 support. Current supported version is 0.13.
  - Added custom options to Gunicorn server.
  - Finally dropped support for type filters. Replace with a custom plugin of needed.

## Release 0.9

Whats new?

- A brand new plugin-API. See Plugins and Plugin Development Guide for details.
- The `route()` decorator got a lot of new features. See `Bottle.route()` for details.
- New server adapters for gevent, meinheld and bjoern.
- Support for SimpleTAL templates.
- Better runtime exception handling for mako templates in debug mode.
- Lots of documentation, fixes and small improvements.
- A new `Request.urlparts` property.

Performance improvements

- The `Router` now special-cases `wsgi.run_once` environments to speed up CGI.
- Reduced module load time by ~30% and optimized template parser. See 8ccb2d, f72a7c and b14b9a for details.
- Support for “App Caching” on Google App Engine. See af93ec.
- Some of the rarely used or deprecated features are now plugins that avoid overhead if the feature is not used.

API changes

This release is mostly backward compatible, but some APIs are marked deprecated now and will be removed for the next release. Most noteworthy:

- The `static` route parameter is deprecated. You can escape wild-cards with a backslash.
- Type-based output filters are deprecated. They can easily be replaced with plugins.

## Release 0.8

API changes

These changes may break compatibility with previous versions.

- The built-in Key/Value database is not available anymore. It is marked deprecated since 0.6.4
- The Route syntax and behaviour changed.
  - Regular expressions must be encapsulated with `#`. In 0.6 all non-alphanumeric characters not present in the regular expression were allowed.
  - Regular expressions not part of a route wildcard are escaped automatically. You don’t have to escape dots or other regular control characters anymore. In 0.6 the whole URL was interpreted as a regular expression. You can use anonymous wildcards (`/index:#(\.html)?#`) to achieve a similar behaviour.
- The `BreakTheBottle` exception is gone. Use `HTTPResponse` instead.
- The `SimpleTemplate` engine escapes HTML special characters in `{{bad_html}}` expressions automatically. Use the new `{{!good_html}}` syntax to get old behaviour (no escaping).
- The `SimpleTemplate` engine returns unicode strings instead of lists of byte strings.
- `bottle.optimize()` and the automatic route optimization is obsolete.
- Some functions and attributes were renamed:
  - `Request._environ` is now `Request.environ`
  - `Response.header` is now `Response.headers`
  - `default_app()` is obsolete. Use `app()` instead.
- The default `redirect()` code changed from 307 to 303.
- Removed support for `@default`. Use `@error(404)` instead.

New features

This is an incomplete list of new features and improved functionality.

- The `Request` object got new properties: `Request.body`, `Request.auth`, `Request.url`, `Request.header`, `Request.forms`, `Request.files`.
- The `Response.set_cookie()` and `Request.get_cookie()` methods are now able to encode and decode python objects. This is called a secure cookie because the encoded values are signed and protected from changes on client side. All pickle-able data structures are allowed.
- The new `Router` class drastically improves performance for setups with lots of dynamic routes and supports named routes (named route + dict = URL string).
- It is now possible (and recommended) to return `HTTPError` and `HTTPResponse` instances or other exception objects instead of raising them.
- The new function `static_file()` equals `send_file()` but returns a `HTTPResponse` or `HTTPError` instead of raising it. `send_file()` is deprecated.
- New `get()`, `post()`, `put()` and `delete()` decorators.
- The `SimpleTemplate` engine got full unicode support.
- Lots of non-critical bugfixes.
