Ticket #4405 – Description

-              initial
+              v1
 ftp://ftp.cwru.edu/pub/bash/readline-8.0.tar.gz
+.  Changes to Readline
+a. Added a guard to prevent nested macros from causing an infinite expansion
+   loop.
+b. Instead of allocating enough history list entries to hold the maximum list
+   size, cap the number allocated initially.
+c. Added a strategy to avoid allocating huge amounts of memory if a block of
+   history entries without timestamps occurs after a block with timestamps.
+d. Added support for keyboard timeouts when an ESC character is the last
+   character in a macro.
+e. There are several performance improvements when in a UTF-8 locale.
+f. Readline does a better job of preserving the original set of blocked
+   signals when using pselect() to wait for input.
+g. Fixed a bug that caused multibyte characters in macros to be mishandled.
+h. Fixed several bugs in the code that calculates line breaks when expanding
+   prompts that span several lines, contain multibyte characters, and contain
+   invisible character seqeuences.
+i. Fixed several bugs in cursor positioning when displaying lines with prompts
+   containing invisible characters and multibyte characters.
+j. When performing case-insensitive completion, Readline no longer sorts the
+   list of matches unless directed to do so.
+k. Fixed a problem with key sequences ending with a backslash.
+l. Fixed out-of-bounds and free memory read errors found via fuzzing.
+m. Fixed several cases where the mark was set to an invalid value.
+n. Fixed a problem with the case-changing operators in the case where the
+   lower and upper case versions of a character do not have the same number
+   of bytes.
+o. Handle incremental and non-incremental search character reads returning EOF.
+p. Handle the case where a failing readline command at the end of a multi-key
+   sequence could be misinterpreted.
+q. The history library now prints a meaningful error message if the history
+   file isn't a regular file.
+r. Fixed a problem with vi-mode redo (`.') on a command when trying to replace
+   a multibyte character.
+s. The key binding code now attempts to remove a keymap if a key unbinding
+   leaves it empty.
+t. Fixed a line-wrapping issue that caused problems for some terminal
+   emulators.
+u. If there is a key bound to the tty's VDISCARD special character, readline
+   disables VDISCARD while it is active.
+v. Fixed a problem with exiting bracketed paste mode on terminals that assume
+   the bracketed paste mode character sequence contains visible characters.
+w. Fixed a bug that could cause a key binding command to refer to an
+   uninitialized variable.
+x. Added more UTF-8-specific versions of multibyte functions, and optimized
+   existing functions if the current locale uses UTF-8 encoding.
+y. Fixed a problem with bracketed-paste inserting more than one character and
+   interacting with other readline functions.
+z. Fixed a bug that caused the history library to attempt to append a history
+   line to a non-existent history entry.
+aa. If using bracketed paste mode, output a newline after the \r that is the
+    last character of the mode disable string to avoid overwriting output.
+bb. Fixes to the vi-mode `b', `B', `w', `W', `e', and `E' commands to better
+    handle multibyte characters.
+cc. Fixed a redisplay problem that caused an extra newline to be generated on
+    accept-line when the line length is exactly the screenwidth.
+dd. Fixed a bug with adding multibyte characters to an incremental search
+    string.
+ee. Fixed a bug with redoing text insertions in vi mode.
+ff. Fixed a bug with pasting text into an incremental search string if bracketed
+    paste mode is enabled. ESC cannot be one of the incremental search
+    terminator characters for this to work.
+gg. Fixed a bug with anchored search patterns when performing searches in vi
+    mode.
+.  New Features in Readline
+a. Non-incremental vi-mode search (`N', `n') can search for a shell pattern, as
+   Posix specifies (uses fnmatch(3) if available).
+b. There are new `next-screen-line' and `previous-screen-line' bindable
+   commands, which move the cursor to the same column in the next, or previous,
+   physical line, respectively.
+c. There are default key bindings for control-arrow-key key combinations.
+d. A negative argument (-N) to `quoted-insert' means to insert the next N
+   characters using quoted-insert.
+e. New public function: rl_check_signals(), which allows applications to
+   respond to signals that readline catches while waiting for input using
+   a custom read function.
+f. There is new support for conditionally testing the readline version in an
+   inputrc file, with a full set of arithmetic comparison operators available.
+g. There is a simple variable comparison facility available for use within an
+   inputrc file. Allowable operators are equality and inequality; string
+   variables may be compared to a value; boolean variables must be compared to
+   either `on' or `off'; variable names are separated from the operator by
+   whitespace.
+h. The history expansion library now understands command and process
+   substitution and extended globbing and allows them to appear anywhere in a
+   word.
+i. The history library has a new variable that allows applications to set the
+   initial quoting state, so quoting state can be inherited from a previous
+   line.
+j. Readline now allows application-defined keymap names; there is a new public
+   function, rl_set_keymap_name(), to do that.
+k. The "Insert" keypad key, if available, now puts readline into overwrite
+   mode.
