+This document details the changes between this version, bash-5.1-rc2, and
+the previous version, bash-5.1-beta.
+
+1. Changes to Bash
+
+a. Process substitutions started from an interactive shell no longer have their
+ standard input implicitly redirected from /dev/null.
+
+b. Fixed an issue with setting the SIGINT trap handler in an interactive shell
+ when temporarily running $PROMPT_COMMAND non-interactively.
+
+2. Changes to Readline
+
+a. Terminals that are named "dumb" or unknown do not enable bracketed paste
+ by default.
+
+b. Ensure that disabling bracketed paste turns off highlighting the incremental
+ search string when the search is successful.
+
+3. New Features in Bash
+
+4. New Features in Readline
+
+------------------------------------------------------------------------------
This document details the changes between this version, bash-5.1-rc1, and
the previous version, bash-5.1-beta.
g. Readline sets the mark in several additional commands.
-h. Bracketed paste mode is enabled by default (for now).
+h. Bracketed paste mode is enabled by default.
i. Readline tries to take advantage of the more regular structure of UTF-8
characters to identify the beginning and end of characters when moving

+subst.c
+ - process_substitute: try it without setting the stdin for a process
+ substitution started from an interactive shell to /dev/null. We will
+ have to see if this causes problems like those reported back in
+ 9/2019 by Grisha Levit. From a report by Hyunho Cho <mug896@gmail.com>
+
+lib/readline/terminal.c
+ - _rl_init_terminal_io: if the terminal is unknown, disable bracketed
+ paste on the assumption it can't handle the enable/disable escape
+ sequences
+
+ 10/8
+ ----
+lib/readline/terminal.c
+ - _rl_init_terminal_io: if the terminal name is "dumb", disable
+ bracketed paste mode. Suggested by
+ Andreas Schwab <schwab@linux-m68k.org>
+
+ 10/13
+ -----
+trap.[ch]
+ - set_trap_state: new function to allow other signal handlers to set
+ the internal state that trap_handler would set to note that the
+ shell received a trapped signal. Used by sigint_sighandler().
+
+sig.c
+ - sigint_sighandler: call set_trap_state to set the pending trap state
+ for SIGINT if trap_handler is not called. Needed because
+ throw_to_top_level now checks whether a signal is pending before
+ running the trap (change from 4/2020)
+
+builtins/trap.def
+ - trap_builtin: if the shell is interactive (interactive_shell != 0)
+ but running something like PROMPT_COMMAND that sets
+ parse_and_execute_level > 0 but interactive == 0, make sure to set
+ the signal handler to the default interactive shell SIGINT handler
+ (sigint_sighandler) instead of the default non-interactive one.
+ Fixes bug reported by Daniel Farina <daniel@fdr.io> with a hint
+ from felix <felix@f-hauri.ch>
+
+ 10/26
+ -----
+
+lib/readline/{readline.c,rlprivate.h}
+ - _rl_enable_active_region: new variable, mirrors value of
+ _rl_enable_bracketed_paste
+ - BRACKETED_PASTE_DEFAULT: new define, default initial value of
+ _rl_enable_bracketed_paste and _rl_enable_active_region
+
+lib/readline/bind.c
+ - hack_special_boolean_var: make sure that _rl_enable_active_region
+ is set appropriately when "enable-bracketed-paste" is modified
+
+lib/readline/isearch.c
+ - _rl_isearch_dispatch: make sure that we activate the mark on finding
+ the search string only if _rl_enable_active_region is non-zero, even
+ if bracketed paste is enabled
+
+lib/readline/search.c
+ - noninc_dosearch: make sure that we activate the mark on finding
+ the search string only if _rl_enable_active_region is non-zero, even
+ if bracketed paste is enabled
+
+lib/readline/kill.c
+ - rl_bracketed_paste_begin: make sure we activate the mark only if
+ _rl_enable_active_region is enabled
+
+lib/readline/isearch.c
+ - _rl_isearch_dispatch: the requirement for number of available unread
+ characters (bytes) to trigger the bracketed paste test is now
+ BRACK_PASTE_SLEN-1, like for non-incremental searches
+
+ 10/29
+ -----
+
+doc/bash.1,lib/readline/rluser.texi
+ - enable-bracketed-paste: change to note the the current default is `On'
+
+ 10/30
+ -----
+lib/glob/glob.c
+ - wdequote_pathname: if wcsrtombs fails, make sure to check whether it
+ leaves wpathname set to a non-NULL value before checking whether or
+ not *wpathname is a null character (indicating an incomplete
+ conversion). Fixes https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=972286
+ with an assist from Bernhard Übelacker <bernhardu@mailbox.org>
+
+ 11/1
+ ----
+lib/readline/isearch.c
+ - _rl_isearch_dispatch: when checking whether the current character is
+ one of the isearch `opcodes', only check the multibyte character
+ member of CXT if we're currently running in a multibyte locale. Don't
+ assume that other parts of the code will set mb[0] = c and mb[1] = 0.
