This document details the changes between this version, bash-5.2-beta, and
the previous version, bash-5.2-alpha.
1. Changes to Bash
a. Fixed a problem with command-oriented history and multi-line commands that
caused embedded blank lines to be run together.
b. Changed the way `&' is quoted when performing pattern substitution and
`patsub_replacement' is enabled.
c. Fixed some integer overflows when expanding strings or reading the output
of command substitution larger than 2GB.
d. `wait -p' without the `-n' option now does something useful if there are no
jobs.
e. Fixed an issue with read timeouts in posix mode.
f. Changed here-document processing to process $'...' and $"..." only when they
appear in the WORD portion of ${PARAM OP WORD} in the here-document body
and the body is being expanded.
g. Changed alias expansion in command substitution to be posix-conformant
(performed while initially parsing the command substitution) when in posix
mode.
h. Bash optimizes away more forks in subshells.
i. Here-document construction now performs quote removal on the here-document
delimiter only if it's marked as quoted, which prevents quote characters in
command substitutions from being removed.
j. Prompt string expansion now gives invisible characters in the expansion of
the \w, \W, and \s escape sequences a visible representation to avoid
problems with redisplay.
k. Fixed a problem with SIGINT during the execution of a command bound with
`bind -x' affecting the saved terminal settings.
l. Fixed an inconsistency with how $@ expands in a construct like ${@:+set}
or ${array[@]:+set} in the presence of null positional parameters or
array elements.
2. Changes to Readline
a. 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.
b. Fixed an issue with multi-line prompt strings that have one or more
invisible characters at the end of a physical line.
c. Fixed an issue that caused a history line's undo list to be cleared when
it should not have been.
3. New Features in Bash
a. There is a new bindable readline command name: `vi-edit-and-execute-command'.
4. New Features in Readline
a. 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.
b. 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.
c. 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.
