IMPROVEMENTS

@@ -2,6 +2,8 @@ Improvements in GNU nano
 ========================
 
 Since 2.9.0:
+  - A key can be bound to a string -- any mix of text and commands.
+  - Error messages are shown by default in bright white on red.
   - <Tab> and <Shift+Tab> can be used to indent/unindent a marked region.
   - Can snip trailing whitespace while typing, with 'set trimblanks'.
   - The ability to record and replay a series of keystrokes (a macro).

NEWS

+2018.03.08 - GNU nano 2.9.4 "Isabel" allows binding a key to a string
+             (any piece of text and/or commands), permits customizing
+             the color of error messages with 'set errorcolor', colors
+             those error messages by default in bright white on red,
+             makes <Enter> at the bottom of the screen scroll just one
+             row when --smooth is used, does not fail when redoing a
+             file insertion, and cancels a Shift-selection when any
+             cursor key is pressed without Shift even when the cursor
+             cannot move.  Further, it treats tabs fully the same as
+             spaces when doing automatic hard-wrapping, allows syntax
+             names to be unquoted, and removes two deprecated options
+             and six deprecated bindable function names.
+
 2018.01.29 - GNU nano 2.9.3 "Córdoba" fixes a segfault with trimblanks
              that could occur when a typed space caused the word after
              it to be pushed to the next line.  It further makes macros

 <h2><a name="1.3"></a>1.3. Why the name change from TIP?</h2>
 <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>
