+
+2006.12.20 - GNU nano 2.0.2 forges ahead.  This release fixes a segfault
+		when trying to save in a nonexistent directory; fixes
+		handling of strings containing nulls at the "Write File",
+		"Insert File", "Execute Command", and "Go to Directory"
+		prompts; fixes several minor memory leaks; fixes two

+
+2006.11.20 - GNU nano 2.0.1 emerges from its cocoon.  This release
+		contains several bugfixes: saving one file over another
+		will now always warn about overwriting it, overwriting
+		a file is no longer possible when saving a new file in
+		restricted mode, and zero-length Unicode characters are
+		now highlighted properly when nano is built without
+		regular expression support.  It also adds several minor
+		documentation updates.  Have fun with it.
+
+2006.11.06 - GNU nano 2.0.0 does its little dance.  This release adds
+		documentation updates and a few cosmetic tweaks.
+			For those who haven't been following nano 1.3
+		development, there are a ton of new features, including
+		support for UTF-8, moving to a specified line and column
+		instead of just a line, improved color syntax
+		highlighting, inserting previously untypeable characters
+		using "Verbatim Input" mode, and copying text into the
+		cutbuffer without cutting it.  There are also fixes for
+		some long-standing bugs, such as the "NumLock glitch"
+		from nano 1.2.x, and the inability to unjustify text
+		after resizing.  Finally, there are also a ton of
+		translation updates and new translations, as well as new
+		color syntaxes.  See the UPGRADE file for more
+		information, and enjoy the new stable release.

+2006.10.25 - GNU nano 1.9.99pre3 learns to appreciate life.  This
+		release fixes a bug where the screen sometimes wouldn't

+		and fixes a few other minor inconsistencies.  Have fun.
+
+2006.10.02 - GNU nano 1.9.99pre2 crosses the threshold.  This release
+		fixes a few more bugs: cursor positioning after leaving
+		the statusbar prompt has been fixed, and verbatim input
+		at the statusbar prompt now properly handles newlines.
+		Enjoy.
+
+2006.08.29 - GNU nano 1.9.99pre1 passes through the flames.  This
+		release fixes various bugs in the last version: the
+		mouse support properly ignores everything except clicks
+		of the left mouse button; the statusbar is now blanked
+		properly when it should be; indenting and unindenting
+		operate on the current line when the mark is off; nano
+		should build on Tru64, NetBSD, and other systems that
+		use termcap instead of terminfo in their curses
+		libraries; the built-in file browser now properly
+		navigates file lists that take up only one row; the
+		cursor position is now completely restored after
+		inserting a file into the current buffer, and after
+		inserting the output of a command into a new buffer; the
+		^X shortcut at the search prompt has been removed, as
+		official Pico doesn't include it and it's too easily
+		confused with Exit; the screen is updated properly after
+		scrolling a line without moving the cursor; the keyboard
+		input routines behave more consistently; and so on.

   <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 today.</p>

 <h2><a name="1.5"></a>1.5. 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>
