 Improvements in GNU nano
 ========================
 
+Since 7.0:
+  - String binds may contain bindable function names between braces.
+  - Word completion looks for candidates in all open buffers.
+  - Unicode codes can be entered without leading zeroes.
+
 Since 6.0:
   - Option --zero hides the interface and uses the whole terminal for editing.
   - Colors can be given also in #rgb hexadecimal, to select the nearest color

+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.
+
+
 2022.08.02 - GNU nano 6.4 "Regentag Dunkelbunt Hundertwasser"
 • The file browser does not crash when moving up to the root folder.
 • Softwrapping very long lines is done more efficiently.

 <h3><a name="1.3"></a>1.3. Why the name change from TIP?</h3>
 <blockquote><p>On January 10, 2000, TIP was officially renamed to nano because of a namespace conflict with another program called 'tip'. The original 'tip' program &quot;establishes a full duplex terminal connection to a remote host&quot;, and was included with many older Unix systems (and newer ones like Solaris). The conflict was not noticed at first because there is no 'tip' utility included with most GNU/Linux distributions (where nano was developed).</p></blockquote>
