 Improvements in GNU nano
 ========================
 
+Since 3.0:
+  - Addition of --zap to make <Del> and <Bsp> obliterate marked text.
+  - <Ctrl+Delete> wipes next word and <Shift+Ctrl+Delete> preceding word.
+  - An external spell check can be undone.
+
 Since 2.9.0:
+  - The ability to filter text through an external command.
+  - Better detection of paragraphs, allowing a less indented beginning.
   - Option 'set afterends' for making Ctrl+Right stop at word ends.
   - A crash handler that saves changed buffers in case of a crash.
   - Addition of the color name "normal", meaning the default color.

+2018.11.11 - GNU nano 3.2 "Het kromme hout" changes the default binding
+             for the linter to M-B so that the spell checker (^T) can
+             always be used, and changes (when linting) the text in the
+             title bar and the color of the status bar to make linting
+             mode more obvious.  It also adds a bindable 'zap' function
+             for deleting a line or marked region without changing the
+             cutbuffer, adds --zap to bind the <Del> and <Backspace>
+             keys to the zap function when something is marked, and
+             hard-binds <Alt+Del> to 'zap'.  Furthermore, it shows the
+             cursor also in the help viewer (when --showcursor is used),
+             renames the bindable functions 'prevhistory' to 'older' and
+             'nexthistory' to 'newer' (update your nanorcs when needed),
+             reads the nanorc files also in restricted mode to allow
+             customization by the user (if this should not be allowed,
+             use --ignorercfiles in addition to --restricted), allows
+             in view mode to open also other files (if this should not
+             be allowed, use --restricted in addition to --view), makes
+             resizes respect a relative --fill again, no longer binds
+             F13...F15 by default, properly re-highlights a misspelled
+             word after invoking help in the internal spell checker,
+             and does not skip Unicode characters in string binds.
+
+2018.09.18 - GNU nano 3.1 "Je faisais des bonds comme ça!" fixes a
+             misbinding of ^H on some terminals and some systems,
+             does not leave stray stuff after the prompt upon exit
+             when having suspended nano while using --constantshow,
+             and does not allow to toggle to Replace in view mode.
+
+2018.09.09 - GNU nano 3.0 "Water Flowing Underground" speeds up the
+             reading of a file by seventy percent, roughly doubles the
+             speed of handling ASCII text, changes the way words at line
+             boundaries are deleted, makes <Ctrl+Delete> wipe the next
+             word and <Ctrl+Shift+Delete> the preceding word, binds M-Q
+             to 'findprevious' by default (the Tabs-to-Spaces toggle is
+             placed on M-O, and the More-Space toggle is fully removed),
+             makes an external spell check undoable, shows the correct
+             number of lines on the status bar when opening multiple
+             files, removes the 'formatter' command, removes the
+             'searchagain' bindable function (M-W is now bound to
+             'findnext' by default), moves the No-Convert toggle to the
+             Insert menu, removes the Backup and New-Buffer toggles from
+             the main menu (they remain in the Write-Out and Insert
+             menus, respectively), is more precise in what it accepts as
+             a rebindable key name, ignores any presses of <Esc> before
+             a valid command keystroke, recognizes some more escape
+             sequences for modified editing-pad keys, does not hide
+             rcfile error messages on a Linux console, renames the
+             bindable functions 'copytext' to 'copy' and 'uncut' to
+             'paste', and avoids a possible hang during a Full-Justify.
+
+
+2018.06.02 - GNU nano 2.9.8 "Espresso" brings the ability to filter the
+             buffer (or the marked region) through an external command
+             (^R^X and prefix the command with the pipe symbol, "|"), is
+             better at detecting and maintaining paragraphs, is able to
+             justify //-style comments, fixes a crash when the binding
+             of a key to a string lacks a closing quote, gives feedback
+             about the number of lines written also when prepending or
+             appending, and fixes a couple of bugs with the linter.
+
 2018.05.15 - GNU nano 2.9.7 "Hvide Sande" adds the option '--afterends'
              for making Ctrl+Right (the nextword function) stop at word

   <p><b>In the beginning...</b></p>
   <p>For years Pine was THE program used to read email on a Unix system. The Pico text editor is the portion of the program one would use to compose his or her mail messages. Many beginners to Unix flocked to Pico and Pine because of their well organized, easy to use interfaces. With the proliferation of GNU/Linux in the mid to late 90's, many University students became intimately familiar with the strengths (and weaknesses) of Pine and Pico.</p>
   <p><b>Then came Debian...</b></p>
-  <p>The <a href="http://www.debian.org/">Debian GNU/Linux</a> distribution, known for its strict standards in distributing truly &quot;free&quot; software (i.e. software with no restrictions on redistribution), would not include a binary package for Pine or Pico. Many people had a serious dilemma: they loved these programs, but the versions available at the time were not truly free software in the <a href="http://www.gnu.org/philosophy/free-sw.html">GNU</a> sense of the word.</p>

   <p><b>The event...</b></p>
   <p>It was in late 1999 when Chris Allegretta (our hero) was yet again complaining to himself about the less-than-perfect license Pico was distributed under, the 1000 makefiles that came with it and how just a few small improvements could make it the Best Editor in the World (TM). Having been a convert from Slackware to Debian, he missed having a simple binary package that included Pine and Pico, and had grown tired of downloading them himself.</p>
   <p>Finally something snapped inside and Chris coded and hacked like a madman for many hours straight one weekend to make a (barely usable) Pico clone, at the time called TIP (Tip Isn't Pico). The program could not be invoked without a filename, could not save files, had no help text display, spell checker, and so forth. But over time it improved, and with the help of a few great coders it matured to the (hopefully) stable state it is in today.</p>

 <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>
