+This document details the changes between this version, readline-4.1,
+and the previous version, readline-4.0.
+
+1. Changes to Readline
+
+a. Changed the HTML documents so that the table-of-contents is no longer
+ a separate file.
+
+b. Changes to the shared object configuration for: Irix 5.x, Irix 6.x,
+ OSF/1.
+
+c. The shared library major and minor versions are now constructed
+ automatically by configure and substituted into the makefiles.
+
+d. It's now possible to install the shared libraries separately from the
+ static libraries.
+
+e. The history library tries to truncate the history file only if it is a
+ regular file.
+
+f. A bug that caused _rl_dispatch to address negative array indices on
+ systems with signed chars was fixed.
+
+g. rl-yank-nth-arg now leaves the history position the same as when it was
+ called.
+
+h. Changes to the completion code to handle MS-DOS drive-letter:pathname
+ filenames.
+
+i. Completion is now case-insensitive by default on MS-DOS.
+
+j. Fixes to the history file manipulation code for MS-DOS.
+
+k. Readline attempts to bind the arrow keys to appropriate defaults on MS-DOS.
+
+l. Some fixes were made to the redisplay code for better operation on MS-DOS.
+
+m. The quoted-insert code will now insert tty special chars like ^C.
+
+n. A bug was fixed that caused the display code to reference memory before
+ the start of the prompt string.
+
+o. More support for __EMX__ (OS/2).
+
+p. A bug was fixed in readline's signal handling that could cause infinite
+ recursion in signal handlers.
+
+q. A bug was fixed that caused the point to be less than zero when rl_forward
+ was given a very large numeric argument.
+
+r. The vi-mode code now gets characters via the application-settable value
+ of rl_getc_function rather than calling rl_getc directly.
+
+s. The history file code now uses O_BINARY mode when reading and writing
+ the history file on cygwin32.
+
+t. Fixed a bug in the redisplay code for lines with more than 256 line
+ breaks.
+
+u. A bug was fixed which caused invisible character markers to not be
+ stripped from the prompt string if the terminal was in no-echo mode.
+
+v. Readline no longer tries to get the variables it needs for redisplay
+ from the termcap entry if the calling application has specified its
+ own redisplay function. Readline treats the terminal as `dumb' in
+ this case.
+
+w. Fixes to the SIGWINCH code so that a multiple-line prompt with escape
+ sequences is redrawn correctly.
+
+x. Changes to the install and install-shared targets so that the libraries
+ and header files are installed separately.
+
+2. New Features in Readline
+
+a. A new Readline `user manual' is in doc/rluserman.texinfo.
+
+b. Parentheses matching is now always compiled into readline, and enabled
+ or disabled when the value of the `blink-matching-paren' variable is
+ changed.
+
+c. MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename.
+
+d. MS-DOS systems now use ~/_history as the default history file.
+
+e. history-search-{forward,backward} now leave the point at the end of the
+ line when the string to search for is empty, like
+ {reverse,forward}-search-history.
+
+f. history-search-{forward,backward} now leave the last history line found
+ in the readline buffer if the second or subsequent search fails.
+
+g. New function for use by applications: rl_on_new_line_with_prompt, used
+ when an application displays the prompt itself before calling readline().
+
+h. New variable for use by applications: rl_already_prompted. An application
+ that displays the prompt itself before calling readline() must set this to
+ a non-zero value.
+
+i. A new variable, rl_gnu_readline_p, always 1. The intent is that an
+ application can verify whether or not it is linked with the `real'
+ readline library or some substitute.
+
+j. Per Bothner's `rlfe' (pronounced `Ralphie') readline front-end program
+ is included in the examples subdirectory, though it is not built
+ by default.
