2019.11.29 - GNU nano 4.6  "And don't you eat that yellow snow"

=E2=80=A2 The 'formatter' command has returned, bound by default to M-F.
  It allows running a syntax-specific command on the contents of
  the buffer.
=E2=80=A2 ^T will try to run 'hunspell' before 'spell', because it checks=

  spellling for the locale's language and understands UTF-8.
=E2=80=A2 Multiple errors or warnings on startup will no longer slow nano=

  down but will be indicated on the status bar with trailing dots.


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