 - When typing in a string in serahc or replace and hitting CASE_SENSITVE
   or the other search string, the current string edit is blown away in
   favor of the last stored search (47) [FIXED]
+- If nano fails to open a file when it starts up,doing almost anything
+  causes a segfault (discovered by Ben Roberts) (48). [FIXED]
+- In certain terminals, nano would not work properly with keypad().
+  Turned out to be the silly timeout(0) call which is completely
+  unneeded anyway.  (49) [FIXED]
+- With less than a page of text, doing a page down will move the

+- with PDCURSES, running meta-X turns off the keypad.  (51) [FIXED]

+nano 0.9.25 - 01/07/2001
+General - 
+	- New file browser code.  New functions in files.c:do_browser(),
+	  helper functions browser_init(), tail(), striponedir(),
+	  filestat().  New shortcut list browser_list.  Some new
+	  strings to translate.  Added function do_browse_from().
+	- Keypad code has been changed slightly.  Now checks for
+	  _use_keypad flag in window to see whether or not to turn 
+	  the keypad() back off when finished (taken from aumix).  Moved
+	  to winio.c where it should probably be anyway.  New confgure
+	  check for _use_keypad in window sstruct.  This will have to do
+	  for now.
+	- Moved keypad() calls for PDCURSES from main() to window_init()
+	  so the keypad continues to work after a Meta-X, for example.
+	  Fixed bug #51.
+- faq.html:
+	- Fix typos and small mistakes (Jordi).
+- files.c:
+  username_tab_completion()
+	- Added the (char *) sizeof when allocating memory for the filename
+	  array (Rocco).
+  cwd_tab_completion()
+	- removed skipping . and .. when tabulating matches.
+	- Added the (char *) sizeof when allocating memory for the filename
+	  array (Rocco).
+  do_writeout()
+	- Now takes an argument so the string typed in can be retained
+	  when calling the browser.
+  do_browser()
+	- Don't decrement longest by the length of path.  Fixes crashes
+	  on entering various dirs  (Rocco).
+	- Don't ungetch() the exit key, unneeded, fixes inerting a file
+	  causes exit code.
+- move.c:
+  page_down()
+	- Don't do an edit_update when there is only one page of text
+	  (fileage == edittop && filebot == editbot).  Fixes Bug #50.
+- nano.c:
+  main()
+	- Reorder the getopt options to be more or less alphabetical
+	  (suggested by Sven Guckes).
+- winio.c:
+  do_cursorpos()
+	- Optimizations and cleanups by Rocco Corsi.
+  do_credits()
+	- Spell Erik Andersen's name right.
+  titlebar()
+	- Now takes an arg, needed for browser function.
+  do_help()
+	- Changed way of temporarily bringing up shortcuts at the
+	  bottom in the help screen (actually works).
+- utils.c:
+  mallocstrcpy()
+	- Takes char pointers now instead of void (makes debugging a
+	  helluva lot easier)
+	- Duh, don't do anything if src == dest!
+- es.po:
+	- Updates for file browser (Jordi).
+
+nano 0.9.24 - 12/18/2000
+General
+	- Added --disable-help option, affects acconfig.h, configure(.in),
+	  winio.c:do_help, nano.c:help_init,help_text_init,version.
+	- Changed filename to no longer use PATH_MAX, so it can work on the
+	  HURD.  Changes in files.c:write_file(), new function
+	  nano.c:clear_filename(), many changed in main(), a few other
+	  places.  Please test this!
+	- Added -b, -e, and -f flags, which we ignore as nano provides 
+	  their functionality already.
+- cut.c:
+  do_uncut_text()
+	- Fix renumbering bug when uncutting marked text at filebot.
+	- Fix screen not being displayed when we are uncutting marked
+	  text at editbot (Bug discovered by Ken Tyler).
+	- Fix magic line not getting created when (you guessed it)
+	  uncutting marked text at filebot (Ryan Krebs).
+- files.c:
+  read_file()
+	- If we encounter an error and insert is not set, run new_file().
+	  (bug discovered by Ben Roberts).
+  write_file()
+	- Change open call flags, basically copy joe's way of doing it so
+	  a more recent version will actually be included in (un)stable.
+	- Remove useless fstat call.
+  open_file()
+	- Added check for S_ISBLK and S_ISCHR, don't open device files!
+- nano.c:
+  renumber()
+	- Dont stupidly assign the value of prev->lineno if prev == NULL!
+  main()
+	- Added code to check for Alt-Alt (27-27) keystrokes and set the
+	  next keystroke as a control sequence.  New variable 
+	  modify_control_key.  Removed #ifdef _POSIX_VDISABLE check
+	  around Control-S,Q,Z handlers because we need it now for
+	  the Alt-Alt-x code.
+	- Added --view option to getopt_long()call .  Bug discovered 
+	  by Rocco Corsi.
+  help_init()
+	- Fix off by one error that was making ^G help in normal mode and
+	  ^_ in pico mode not be displayed in the help (bug discovered by
+	  Rocco Corsi).
+  do_toggle()
+	- Added fix_editbot() call to fix improper redisplay of edit
+	  window when using nohelp toggle (bug discovered by Rocco Corsi).
+- nano.1, nano.1.html:
+	- Updated man page for -b, -e, -f and expanded explanation for -p.
+- winio.c
+  do_help()
+	- Force keypad on so F-keys and PageUp/Down will work properly.
+	  Added check for NANO_EXIT_FKEY to loop.
+- utils.c:
+  new_magicline()
+	- Increment totsize!!  We decrement it when we've read a file, 
+	  everywhere else it should automatically be incremented

+01/07/2001 - Nano 0.9.25 is the "Just one more feature I swear!" release.
+		It includes one new feature that Pico has had forever, a

+		option, there is a --disable-browser option to the
+		configure script as well.  Other changes include slightly

+12/18/2000 - Nano 0.9.24 is released.  This versions contains the last of

+		refuses to open device files, to stop silly things like

-	The nano editor (Nano's ANOther editor) by Chris Allegretta
+	nano - a GPLed, enhanced clone of the Pico text editor.
                                       
-Manifesto
+Overview
+
+     The nano project was started because of a few "problems" with the
+     wonderfully easy-to-use and friendly Pico text editor.
+
+     First and foremost is its license: the Pine suite does not use the
+     GPL or a GPL-friendly license, and has unclear restrictions on 
+     redistribution.  Because of this, Pine and Pico are not included with
+     many GNU/Linux distributions.  Also, other features (like goto line
+     number or search and replace) were unavailable until recently or
+     require a command-line flag.  Yuck.
 
-     Nano is the editor formerly known as TIP (TIP Isn't Pico).
-     The nano project was started because of three main problems with the
-     wonderfully easy-to-use and friendly Pico text editor:
-     
-     - It's license is not the GNU GPL, and hence some Linux
-     distributions, including Debian (my favorite) don't always
-     include it/don't include binaries.  This is not necessarily a
-     problem, but an issue nonetheless.
-     
-     - Until recently, it had no ability to go to a line # from within
-     the editor. There was the +number command line option, but who wants
-     to exit a file to go to a specific line number? When I want to go to
-     a line, since I have to exit anyway, I just call up vi temporarily.
-     
-     - No search and replace feature. Well, apparently there is a flag
-     that lets you do a search and replace (-b in newer versions) but,
-     well, I still dont like it.
-     
      nano aims to solve these problems by emulating the functionality of
      Pico as closely as possible while adressing the problems above and
      perhaps providing other extra functionality.
