2.5.0 (October 23, 2024)

• Breaking Change
  • cmd2 2.5 supports Python 3.8+ (removed support for Python 3.6 and 3.7)
• Bug Fixes
  • Fixed issue where persistent history file was not saved upon SIGHUP and SIGTERM signals.
  • Multiline commands are no longer fragmented in up-arrow history.
  • Fixed bug where async_alert() overwrites readline's incremental and non-incremental search prompts.
    • This fix introduces behavior where an updated prompt won't display after an aborted search
      until a user presses Enter. See async_printing.py
      example for how to handle this case using Cmd.need_prompt_refresh() and Cmd.async_refresh_prompt().
• Enhancements
  • Removed dependency on attrs and replaced with dataclasses
  • add allow_clipboard initialization parameter and attribute to disable ability to
    add output to the operating system clipboard
  • Updated unit tests to be Python 3.13 compliant.
  • Fall back to bz2 compression of history file when lzma is not installed.
  • Added settable called scripts_add_to_history which determines whether scripts and pyscripts
    add commands to history.
• Deletions (potentially breaking changes)
  • Removed apply_style from Cmd.pwarning().
