## 0.8.5 (April 15, 2018)
* Bug Fixes
* Fixed a bug with all argument decorators where the wrapped function wasn't returning a value and thus couldn't cause the cmd2 app to quit
* Enhancements
* Added support for verbose help with -v where it lists a brief summary of what each command does
* Added support for categorizing commands into groups within the help menu
* See the [Grouping Commands](http://cmd2.readthedocs.io/en/latest/argument_processing.html?highlight=verbose#grouping-commands) section of the docs for more info
* See [help_categories.py](https://github.com/python-cmd2/cmd2/blob/master/examples/help_categories.py) for an example
* Tab completion of paths now supports ~user user path expansion
* Simplified implementation of various tab completion functions so they no longer require ``ctypes``
* Expanded documentation of ``display_matches`` list to clarify its purpose. See cmd2.py for this documentation.
* Adding opening quote to tab completion if any of the completion suggestions have a space.
* **Python 2 EOL notice**
* This is the last release where new features will be added to ``cmd2`` for Python 2.7
* The 0.9.0 release of ``cmd2`` will support Python 3.4+ only
* Additional 0.8.x releases may be created to supply bug fixes for Python 2.7 up until August 31, 2018
* After August 31, 2018 not even bug fixes will be provided for Python 2.7
## 0.8.4 (April 10, 2018)
* Bug Fixes
* Fixed conditional dependency issue in setup.py that was in 0.8.3.
## 0.8.3 (April 09, 2018)
* Bug Fixes
* Fixed ``help`` command not calling functions for help topics
* Fixed not being able to use quoted paths when redirecting with ``<`` and ``>``
* Enhancements
* Tab completion has been overhauled and now supports completion of strings with quotes and spaces.
* Tab completion will automatically add an opening quote if a string with a space is completed.
* Added ``delimiter_complete`` function for tab completing delimited strings
* Added more control over tab completion behavior including the following flags. The use of these flags is documented in cmd2.py
* ``allow_appended_space``
* ``allow_closing_quote``
* Due to the tab completion changes, non-Windows platforms now depend on [wcwidth](https://pypi.python.org/pypi/wcwidth).
* An alias name can now match a command name.
* An alias can now resolve to another alias.
* Attribute Changes (Breaks backward compatibility)
* ``exclude_from_help`` is now called ``hidden_commands`` since these commands are hidden from things other than help, including tab completion
* This list also no longer takes the function names of commands (``do_history``), but instead uses the command names themselves (``history``)
* ``excludeFromHistory`` is now called ``exclude_from_history``
* ``cmd_with_subs_completer()`` no longer takes an argument called ``base``. Adding tab completion to subcommands has been simplified to declaring it in the
subcommand parser's default settings. This easily allows arbitrary completers like path_complete to be used.
See [subcommands.py](https://github.com/python-cmd2/cmd2/blob/master/examples/subcommands.py) for an example of how to use
tab completion in subcommands. In addition, the docstring for ``cmd_with_subs_completer()`` offers more details.
## 0.8.2 (March 21, 2018)
* Bug Fixes
* Fixed a bug in tab-completion of command names within sub-menus
* Fixed a bug when using persistent readline history in Python 2.7
* Fixed a bug where the ``AddSubmenu`` decorator didn't work with a default value for ``shared_attributes``
* Added a check to ``ppaged()`` to only use a pager when running in a real fully functional terminal
* Enhancements
* Added [quit_on_sigint](http://cmd2.readthedocs.io/en/latest/settingchanges.html#quit-on-sigint) attribute to enable canceling current line instead of quitting when Ctrl+C is typed
* Added possibility of having readline history preservation in a SubMenu
* Added [table_display.py](https://github.com/python-cmd2/cmd2/blob/master/examples/table_display.py) example to demonstrate how to display tabular data
* Added command aliasing with ``alias`` and ``unalias`` commands
* Added the ability to load an initialization script at startup
* See [alias_startup.py](https://github.com/python-cmd2/cmd2/blob/master/examples/alias_startup.py) for an example
* Added a default SIGINT handler which terminates any open pipe subprocesses and re-raises a KeyboardInterrupt
* For macOS, will load the ``gnureadline`` module if available and ``readline`` if not

* See [tab_completion.py](https://github.com/python-cmd2/cmd2/blob/master/examples/tab_completion.py)
* Added support for displaying output which won't fit on the screen via a pager using ``ppaged()``
* See [paged_output.py](https://github.com/python-cmd2/cmd2/blob/master/examples/paged_output.py)
* Attributes Removed (**can cause breaking changes**)
* ``abbrev`` - Removed support for abbreviated commands
* Good tab completion makes this unnecessary and its presence could cause harmful unintended actions
* ``case_insensitive`` - Removed support for case-insensitive command parsing
* Its presence wasn't very helpful and could cause harmful unintended actions
## 0.8.0 (February 1, 2018)
* Bug Fixes
* Fixed unit tests on Python 3.7 due to changes in how re.escape() behaves in Python 3.7

* **with_arparser** decorator for strict argparse-based argument parsing of command arguments
* **do_*** commands get a single argument which is the output of argparse.parse_args()
* **with_argparser_and_unknown_args** decorator for argparse-based argument parsing, but allows unknown args
* **do_*** commands get two arguments, the output of argparse.parse_known_args()
* See the [Argument Processing](http://cmd2.readthedocs.io/en/latest/argument_processing.html) section of the documentation for more information on these decorators
* Alternatively, see the [argparse_example.py](https://github.com/python-cmd2/cmd2/blob/master/examples/argparse_example.py)
and [arg_print.py](https://github.com/python-cmd2/cmd2/blob/master/examples/arg_print.py) examples
* Added support for Argparse sub-commands when using the **with_argument_parser** or **with_argparser_and_unknown_args** decorators
* See [subcommands.py](https://github.com/python-cmd2/cmd2/blob/master/examples/subcommands.py) for an example of how to use subcommands
* Tab-completion of sub-command names is automatically supported
* The **__relative_load** command is now hidden from the help menu by default
* This command is not intended to be called from the command line, only from within scripts
* The **set** command now has an additional **-a/--all** option to also display read-only settings
* The **history** command can now run, edit, and save prior commands, in addition to displaying prior commands.
* The **history** command can now automatically generate a transcript file for regression testing
* This makes creating regression tests for your ``cmd2`` application trivial
* Commands Removed
* The **cmdenvironment** has been removed and its functionality incorporated into the **-a/--all** argument to **set**
* The **show** command has been removed. Its functionality has always existing within **set** and continues to do so
* The **save** command has been removed. The capability to save commands is now part of the **history** command.
* The **run** command has been removed. The capability to run prior commands is now part of the **history** command.
* Other changes
* The **edit** command no longer allows you to edit prior commands. The capability to edit prior commands is now part of the **history** command. The **edit** command still allows you to edit arbitrary files.
* the **autorun_on_edit** setting has been removed.
* For Python 3.4 and earlier, ``cmd2`` now has an additional dependency on the ``contextlib2`` module
* Deprecations
* The old **options** decorator for optparse-based argument parsing is now *deprecated*
* The old decorator is still present for now, but will be removed in a future release
* ``cmd2`` no longer includes **optparse.make_option**, so if your app needs it import directly from optparse
## 0.7.9 (January 4, 2018)
* Bug Fixes
* Fixed a couple broken examples
* Enhancements
* Improved documentation for modifying shortcuts (command aliases)
* Made ``pyreadline`` a dependency on Windows to ensure tab-completion works
* Other changes
* Abandoned official support for Python 3.3. It should still work, just don't have an easy way to test it anymore.
## 0.7.8 (November 8, 2017)
* Bug Fixes
* Fixed ``poutput()`` so it can print an integer zero and other **falsy** things
* Fixed a bug which was causing autodoc to fail for building docs on Readthedocs

* Added ``runcmds_plus_hooks()`` method to run multiple commands w/o a cmdloop
## 0.7.7 (August 25, 2017)
* Bug Fixes
* Added workaround for bug which occurs in Python 2.7 on Linux when ``pygtk`` is installed
* ``pfeedback()`` now honors feedback_to_output setting and won't redirect when it is ``False``
* For ``edit`` command, both **editor** and **filename** can now have spaces in the name/path
* Fixed a bug which occurred when stdin was a pipe instead of a tty due to input redirection
* Enhancements
* ``feedback_to_output`` now defaults to ``False`` so info like command timing won't redirect
* Transcript regular expressions now have predictable, tested, and documented behavior
* This makes a breaking change to the format and expectations of transcript testing
* The prior behavior removed whitespace before making the comparison, now whitespace must match exactly
* Prior version did not allow regexes with whitespace, new version allows any regex
* Improved display for ``load`` command and input redirection when **echo** is ``True``
## 0.7.6 (August 11, 2017)
* Bug Fixes
* Case-sensitive command parsing was completely broken and has been fixed

* Greatly improved implementation for how command output gets piped to a shell command
## 0.7.5 (July 8, 2017)
* Bug Fixes
* `case_insensitive` is no longer a runtime-settable parameter, but it was still listed as such

* Added additional command abbreviations to the "exclude from history" list
* Fixed argparse_example.py and pirate.py examples and transcript_regex.txt transcript
* Fixed a bug in a unit test which occurred under unusual circumstances
* Enhancements
* Organized all attributes used to configure the ParserManager into a single location
* Set the default value of `abbrev` to `False` (which controls whether or not abbreviated commands are allowed)
* With good tab-completion of command names, using abbreviated commands isn't particularly useful
* And it can create complications if you are't careful
* Improved implementation of `load` to use command queue instead of nested inner loop
## 0.7.4 (July 3, 2017)
* Bug fixes
* Fixed a couple bugs in interacting with pastebuffer/clipboard on macOS and Linux
* Fixed a couple bugs in edit and save commands if called when history is empty
* Ability to pipe ``cmd2`` command output to a shell command is now more reliable, particularly on Windows
* Fixed a bug in ``pyscript`` command on Windows related to ``\`` being interpreted as an escape
* Enhancements
* Ensure that path and shell command tab-completion results are alphabetically sorted
* Removed feature for load command to load scripts from URLS
* It didn't work, there were no unit tests, and it felt out of place

* Redundant **list** command removed and features merged into **history** command
* Added **pyscript** command which supports tab-completion and running Python scripts with arguments
* Improved tab-completion of file system paths, command names, and shell commands
* Thanks to Kevin Van Brunt for all of the help with debugging and testing this
* Changed default value of USE_ARG_LIST to True - this affects the beavhior of all **@options** commands
* **WARNING**: This breaks backwards compatibility, to restore backwards compatibility, add this to the
**__init__()** method in your custom class derived from cmd2.Cmd:
* cmd2.set_use_arg_list(False)
* This change improves argument parsing for all new applications
* Refactored code to encapsulate most of the pyparsing logic into a ParserManager class
