+This document details the changes between this version, readline-8.2, and
+the previous version, readline-8.1.
+
+1. Changes to Readline
+
+a. Fixed a problem with cleaning up active marks when using callback mode.
+
+b. Fixed a problem with arithmetic comparison operators checking the version.
+
+c. Fixed a problem that could cause readline not to build on systems without
+ POSIX signal functions.
+
+d. Fixed a bug that could cause readline to crash if the application removed
+ the callback line handler before readline read all typeahead.
+
+e. Added additional checks for read errors in the middle of readline commands.
+
+f. Fixed a redisplay problem that occurred when switching from the digit-
+ argument prompt `(arg: N)' back to the regular prompt and the regular
+ prompt contained invisible characters.
+
+g. Fixed a problem with restoring the prompt when aborting an incremental
+ search.
+
+h. Fix a problem with characters > 128 not being displayed correctly in certain
+ single-byte encodings.
+
+i. Fixed a problem with unix-filename-rubout that caused it to delete too much
+ when applied to a pathname consisting only of one or more slashes.
+
+j. Fixed a display problem that caused the prompt to be wrapped incorrectly if
+ the screen changed dimensions during a call to readline() and the prompt
+ became longer than the screen width.
+
+k. Fixed a problem that caused the \r output by turning off bracketed paste
+ to overwrite the line if terminal echo was disabled.
+
+l. Fixed a bug that could cause colored-completion-prefix to not display if
+ completion-prefix-display-length was set.
+
+m. Fixed a problem with line wrapping prompts when a group of invisible
+ characters runs to the right edge of the screen and the prompt extends
+ longer then the screen width.
+
+n. Fixed a couple problems that could cause rl_end to be set incorrectly by
+ transpose-words.
+
+o. Prevent some display problems when running a command as the result of a
+ trap or one bound using `bind -x' and the command generates output.
+
+p. Fixed an issue with multi-line prompt strings that have one or more
+ invisible characters at the end of a physical line.
+
+q. Fixed an issue that caused a history line's undo list to be cleared when
+ it should not have been.
+
+2. New Features in Readline
+
+a. There is now an HS_HISTORY_VERSION containing the version number of the
+ history library for applications to use.
+
+b. History expansion better understands multiple history expansions that may
+ contain strings that would ordinarily inhibit history expansion (e.g.,
+ `abc!$!$').
+
+c. There is a new framework for readline timeouts, including new public
+ functions to set timeouts and query how much time is remaining before a
+ timeout hits, and a hook function that can trigger when readline times
+ out. There is a new state value to indicate a timeout.
+
+d. Automatically bind termcap key sequences for page-up and page-down to
+ history-search-backward and history-search-forward, respectively.
+
+e. There is a new `fetch-history' bindable command that retrieves the history
+ entry corresponding to its numeric argument. Negative arguments count back
+ from the end of the history.
+
+f. `vi-undo' is now a bindable command.
+
+g. There is a new option: `enable-active-region'. This separates control of
+ the active region and bracketed-paste. It has the same default value as
+ bracketed-paste, and enabling bracketed paste enables the active region.
+ Users can now turn off the active region while leaving bracketed paste
+ enabled.
+
+h. rl_completer_word_break_characters is now `const char *' like
+ rl_basic_word_break_characters.
+
+i. Readline looks in $LS_COLORS for a custom filename extension
+ (*.readline-colored-completion-prefix) and uses that as the default color
+ for the common prefix displayed when `colored-completion-prefix' is set.
+
+j. Two new bindable string variables: active-region-start-color and
+ active-region-end-color. The first sets the color used to display the
+ active region; the second turns it off. If set, these are used in place
+ of terminal standout mode.
+
+k. New readline state (RL_STATE_EOF) and application-visible variable
+ (rl_eof_found) to allow applications to detect when readline reads EOF
+ before calling the deprep-terminal hook.
+
+l. There is a new configuration option: --with-shared-termcap-library, which
+ forces linking the shared readline library with the shared termcap (or
+ curses/ncurses/termlib) library so applications don't have to do it.
