[ANNOUNCE] nano-7.0 is released

2022.11.15 - GNU nano 7.0  "Una existencia simple bajo el sol"

• String binds may contain bindable function names between braces.
   For example, to move the current line down to after the next one:
   bind ^D "{cut}{down}{paste}{up}" main.  Of course, braced function
   names may be mixed with literal text.  If an existing string bind
   contains a literal {, replace it with {{}.
• Unicode codes can be entered (via M-V) without leading zeroes,
   by finishing short codes with <Space> or <Enter>.
• Word completion (^]) looks for candidates in all open buffers.
• No regular expression matches the final empty line any more.


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