+  Added -Ps to change the default short prompt (same as plain -P).
+
+* Ported to the Borland C compiler for MS-DOS.
+
+* Ported to Windows 95 & Windows NT.
+
+* Ported to OS-9.
+
+* Ported to GNU Hurd.
+
+======================================================================
+
+
+	Major changes between "less" versions 290 and 291
+
+* Less environment variables can be specified in lesskey files.
+
+* Fixed MS-DOS build.
+
+======================================================================
+
+
+	Major changes between "less" versions 278 and 290
+
+* Accepts GNU-style options "--help" and "--version".
+
+* OS/2 version looks for less.ini in $HOME before $INIT and $PATH.
+
+* Bug fixes
+
+======================================================================
+
+
+	Major changes between "less" versions 252 and 278
+
+* A LESSOPEN preprocessor may now pipe the converted file data to less,
+  rather than writing it to a temporary file.
+
+* Search pattern highlighting has been fixed.  It now highlights 
+  reliably, even if a string is split across two screen lines,
+  contains TABs, etc.
+
+* The -F flag (which suppress search highlighting) has been changed 
+  to -G.  A new flag, -g, changes search highlighting to highlight 
+  only the string found by the last search command, instead of all 
+  strings which match the last search command.
+
+* New flag -I acts like -i, but ignores case even if the search 
+  pattern contains uppercase letters.
+
+* Less now checks for the environment variable VISUAL before EDITOR.
+
+* Ported to OS/2.
+
+======================================================================
+
+
+	Major changes between "less" versions 237 and 252
+
+* Changes in line-editing keys:
+  The literal key is now ^V or ^A rather than \ (backslash).
+  Filename completion commands (TAB and ^L) are disabled 
+  when typing a search pattern.
+
+* Line-editing command keys can be redefined using lesskey.
+
+* Lesskey with no input file defaults to $HOME/.lesskey
+  rather than standard input.
+
+* New option -V displays version number of less.
+
+* New option -V displays version number of lesskey.
+
+* Help file less.hlp is now installed by default in /usr/local/share 
+  rather than /usr/local/lib.
+
+
+======================================================================
+
+
+	Major changes between "less" versions 170 and 237
+
+* By popular demand, text which matches the current search pattern
+  is highlighted.  New -F flag disables this feature.
+
+* Henry Spencer's regexp.c is now included, for systems which do not
+  have a regular expression library.
+  regexp.c is Copyright (c) 1986 by University of Toronto.
+
+* New line-editing keys, including command history (arrow keys) and 
+  filename completion (TAB).
+
+* Input preprocessor allows modification of input files (e.g. uncompress)
+  via LESSOPEN/LESSCLOSE environment variables.
+
+* New -X flag disables sending termcap "ti" and "te" (initialize and
+  deinitialize) strings to the terminal. 
+
+* Changing -i from within less now correctly affects a subsequent
+  repeated search.  
+
+* Searching for underlined or overstruck text now works when the -u
+  flag is in effect, rather than the -i flag.
+
+* Use setlocale (LANG and LC_CTYPE environment variables) to determine
+  the character set if LESSCHARSET/LESSCHARDEF are not set.
+
+* The default format for displaying binary characters is now standout
+  (reverse video) rather than blinking.  This can still be changed by
+  setting the LESSBINFMT environment variable.
+
+* Use autoconf installation technology.
+
+* Ported to MS-DOS.
+
+        ********************************
+          Things that may surprise you
+        ********************************
+
+* When you enter text at the bottom of the screen (search string, 
+  filename, etc.), some keys act different than previously.  
+  Specifically, \ (backslash), ESC, TAB, BACKTAB, and control-L 
+  now have line editing functions.
+
+* Some previous unofficial versions of less were able to display
+  compressed files.  The new LESSOPEN/LESSCLOSE feature now provides
+  this functionality in a different way.
+
+* Some previous unofficial versions of less provided a -Z flag to 
+  set the number of lines of text to retain between full screen scrolls.
+  The -z-n flag (that is, -z with a negative number) provides this 
+  functionality.
+
+
+======================================================================
+
+
+	Major changes between "less" versions 123 and 170
+
+* New option -j allows target lines to be positioned anywhere on screen.
+
+* New option -S truncates displayed line at the screen width,
+  rather than wrapping onto the next line.
+
+* New option -y limits amount of forward scroll.
+
+* New option -T specifies a "tags" file.
+
+* Non-printable, non-control characters are displayed in octal.
+  Such characters, as well as control characters, are displayed 
+  in blinking mode.
+
+* New command -+ sets an option to its default.
+* New command -- sets an option to the opposite of its default.
+
+* Lesskey file may have a string appended to a key's action,
+  which acts as though typed in after the command.
+
+* New commands ESC-^F and ESC-^B match arbitrary types of brackets.
+
+* New command F monitors a growing file (like "tail -f").
+
+* New command | pipes a section of the input file into a shell command.
+
+* New command :x directly jumps to a file in the command line list.
+
+* Search commands have been enhanced and reorganized:
+	n	Repeat search, same direction.
+	N	Repeat search, opposite direction.
+	ESC-/	Search forward thru file boundaries
+	ESC-?	Search backward thru file boundaries
+	ESC-n	Repeat search thru file boundaries, same direction.
+	ESC-N	Repeat search thru file boundaries, opposite direction.
+  Special character * causes search to search thru file boundaries.
+  Special character @ causes search to begin at start/end of file list.
+
+* Examining a new file adds it to the command line list.
+  A list of files, or an expression which matches more than one file,
+  may be examined; all of them are added to the command line list.
+
+* Environment variables LESSCHARSET and LESSCHARDEF can define
+  a non-ASCII character set.
+
+* Partial support for MSDOS, including options -R for repainting screen
+  on quit, -v/-V to select video mode, and -W to change window size.
+
+
+======================================================================
+
+
+	Major changes between "less" versions 97 and 123
+
+* New option (-N) causes line numbers to be displayed in the
+  text of the file (like vi "set nu").
+
+* New option (-?) prints help message immediately.
+
+* New option (-r) displays "raw" control characters, without
+  mapping them to ^X notation.
+
+* New option (-f) forces less to open non-regular files
+  (directories, etc).
+
+* New option (-k) can be used to specify lesskey files by name.
+
+* New option (-y) can be used to set a forward scroll limit
+  (like -h sets a backward scroll limit).
+
+* File marks (set by the m command) are now preserved when a new
+  file is edited.  The ' command can thus be used to switch files.
+
+* New command ESC-/ searches all files (on the command line) 
+  for a pattern.
+
+* New command ESC-n repeats previous search, spanning files.
+
+* The N command has been changed to repeat the previous search
+  in the reverse direction.  The old N command is still available 
+  via :n.
+
+* New command ESC-N repeats previous search in the reverse
+  direction and spanning files.
+
+* 8 bit characters are now supported.  A new option (-g) can be 
+  used to strip off the eighth bit (the previous behavior).
+
+* Options which take a following string (like -t) may now
+  optionally have a space between the option letter and the string.
+
+* Six new commands { } ( ) [ and ] can be used to match
+  brackets of specific types, similar to vi % command.
+
+* New commands z and w move forward/backward one window and
+  simultaneously set the window size.
+
+* Prompt string expansion now has %L for line number of the last
+  line in the file, and %E for the name of the editor.
+  Also, % escapes which refer to a line (b=bottom, t=top, etc.)
+  can use j for the jump target line.
+
+* New environment variable LESSEDIT can be used to tailor the
+  command string passed to the editor by the v command.
+
+* Examining a file which was previously examined will return
+  to the same position in the file.
+
+* A "%" is expanded to the current filename and a "#" to the 
+  previous filename, in both shell commands and the E command.
+  (Previously % worked only in shell commands and # worked 
+  only in the E command.)
+
+* New command ":ta" is equivalent to "-t".
+
+* New command "s" is equivalent to "-l".
+
+* The - command may be followed by "+X" to revert to the default
+  for option X, or "-X" to get the opposite of the default.
+
+* Lesskey files may now include characters after the action as
+  extra input to be parsed after the action; for example:
+  "toggle-option X" to toggle a specific option X.
