[ANNOUNCE] nano-5.6 is released

[Benno Schulenberg]

2021.02.24 - GNU nano 5.6  "Wielewaal"

• A search match gets highlighted (in black on yellow by default),
  in addition to placing the cursor at the start of the match.
  The color combination can be changed with 'set highlightcolor'.
  By default the cursor is hidden until the next keystroke, but
  it can be forced on with --showcursor / 'set showcursor'.
• Option --markmatch / 'set markmatch' has been removed.
• Cursor position and character code are displayed in the minibar
  only when option --constantshow / 'set constantshow' is used,
  and their display can be toggled with M-C.
• The state flags are displayed in the minibar only when option
  --stateflags / 'set stateflags' is used.


GNU nano is a simple and easy-to-use editor for on the terminal.
