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.
- 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 for an example of how to use
  tab completion in subcommands. In addition, the docstring for cmd_with_subs_completer() offers more details.

0.8.0 (February 1, 2018)

Bug Fixes
- Fixed unit tests on Python 3.7 due to changes in how re.escape() behaves in Python 3.7
- Fixed a bug where unknown commands were getting saved in the history
Enhancements
- Three new decorators for do_* commands to make argument parsing easier
  - with_argument_list decorator to change argument type from str to List[str]
    - do_* commands get a single argument which is a list of strings, as pre-parsed by shlex.split()
  - with_argparser 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 section of the documentation for more information on these decorators
  - Alternatively, see the argparse_example.py
    and arg_print.py examples
- Added support for Argpasre sub-commands when using the with_argument_parser or with_argparser_and_unknown_args decorators
  - See 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

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
- Fixed bug due to pyperclip dependency radically changing its project structure in latest version
Enhancements
- Improved documentation for user-settable environment parameters
- Improved documentation for overriding the default supported comment styles
- 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

- Fixed some timing bugs when running unit tests in parallel by using monkeypatch

08 Jul 19:41

Release date: 2017-07-08

Bug Fixes
- case_insensitive is no longer a runtime-settable parameter, but it was still listed as such
- Fixed a recursive loop bug when abbreviated commands are enabled and it could get stuck in the editor forever
  - 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
