[ANNOUNCE] nano-8.0 is released

[Benno Schulenberg]

2024.05.01 - GNU nano 8.0  "Grus grus"

• By default ^F is bound to starting a forward search, and ^B to
  starting a backward search, while M-F and M-B repeat the search
  in the corresponding direction.  (See the documentation if you
  want the old bindings back.)
• Command-line option --modernbindings (-/) makes ^Q quit, ^X cut,
  ^C copy, ^V paste, ^Z undo, ^Y redo, ^O open a file, ^W write a
  file, ^R replace, ^G find again, ^D find again backwards, ^A set
  the mark, ^T jump to a line, ^P show the position, and ^E execute.
• Above modern bindings are activated also when the name of nano's
  executable (or a symlink to it) starts with the letter "e".
• To open a file at a certain line number, one can now use also
  `nano filename:number`, besides `nano +number filename`.
• <Alt+Home> and <Alt+End> put the cursor on the first and last
  row in the viewport, while retaining the horizontal position.
• When the three digits in an #RGB color code are all the same,
  the code is mapped to the xterm grey scale, giving access to
  fourteen levels of grey instead of just four.
• For easier access, M-" is bound to placing/removing an anchor,
  and M-' to jumping to the next anchor.
• Whenever an error occurs, the keystroke buffer is cleared, thus
  stopping the execution of a macro or a string bind.
• The mousewheel scrolls the viewport instead of moving the cursor


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