2.3.0 (November 11, 2021)

• Bug Fixes
  • Fixed AttributeError in rl_get_prompt() when prompt is None.
  • Fixed bug where using choices on a Settable didn't verify that a valid choice had been entered.
  • Fixed bug introduced in cmd2 2.0.0 in which select() converts return values to strings. It should never
    have converted return values.
• Enhancements
  • Added settings to Column class which prevent a table from overriding existing styles in header
    and/or data text. This allows for things like nesting an AlternatingTable in another AlternatingTable.
  • AlternatingTable no longer automatically applies background color to borders. This was done to improve
    appearance since the background color extended beyond the borders of the table.
  • Added ability to colorize all aspects of AlternatingTables, BorderedTables, and SimpleTables.
  • Added support for 8-bit/256-colors with the cmd2.EightBitFg and cmd2.EightBitBg classes.
  • Added support for 24-bit/RGB colors with the cmd2.RgbFg and cmd2.RgbBg classes.
  • Removed dependency on colorama.
  • Changed type of ansi.allow_style from a string to an ansi.AllowStyle Enum class.
• Deprecations
  • Deprecated cmd2.fg. Use cmd2.Fg instead.
  • Deprecated cmd2.bg. Use cmd2.Bg instead.
• Breaking Changes
  • To support the color upgrade, all cmd2 colors now inherit from either ansi.FgColor or ansi.BgColor.
    Therefore, ansi.style() no longer accepts colors as strings.
