Released 2014-08-22

- Added missing ``err`` parameter forwarding to the ``secho``
function.
- Fixed default parameters not being handled properly by the context
invoke method. This is a backwards incompatible change if the
function was used improperly.
- Removed the ``invoked_subcommands`` attribute largely. It is not
possible to provide it to work error free due to how the parsing
works so this API has been deprecated.
- Restored the functionality of ``invoked_subcommand`` which was
broken as a regression in 3.1.

-----------

Released 2014-08-13

- Fixed a regression that caused contexts of subcommands to be created
before the parent command was invoked which was a regression from
earlier Click versions.

Released 2014-08-12, codename "clonk clonk"

- Formatter now no longer attempts to accommodate for terminals
smaller than 50 characters. If that happens it just assumes a
minimal width.
- Added a way to not swallow exceptions in the test system.
- Added better support for colors with pagers and ways to override the
autodetection.
- The CLI runner's result object now has a traceback attached.
- Improved automatic short help detection to work better with dots
that do not terminate sentences.
- When defining options without actual valid option strings now,
Click will give an error message instead of silently passing. This
should catch situations where users wanted to created arguments
instead of options.
- Restructured Click internally to support vendoring.
- Added support for multi command chaining.
- Added support for defaults on options with ``multiple`` and options
and arguments with ``nargs != 1``.
- Label passed to ``progressbar`` is no longer rendered with
whitespace stripped.
- Added a way to disable the standalone mode of the ``main`` method on
a Click command to be able to handle errors better.
- Added support for returning values from command callbacks.
- Added simplifications for printing to stderr from ``echo``.
- Added result callbacks for groups.
- Entering a context multiple times defers the cleanup until the last
exit occurs.
- Added ``open_file``.
