should output the same thing. From a report from Dan Jacobson
<jidanni@jidanni.org> back in 1/2019.
+
+ 3/23
+ ----
+subst.c
+ - string_transform: add `U' (convert to uppercase), `u' (convert
+ first character to uppercase), and `L' (convert to lowercase)
+ transformations. Inspired by a discussion with Phil Smith
+ <phil@philsmith.com> back in May, 2019
+ - parameter_brace_transform: make sure `u', `U', and `L' are valid
+ transform operators
+
+doc/{bash.1,bashref.texi}
+ - parameter transformation: document new `U', `u', and `L' operators
+
+eval.c
+ - execute_prompt_command: if an array variable PROMPT_COMMANDS exists,
+ prefer it to PROMPT_COMMAND and execute all of the commands contained
+ as array elements in index order. From a proposal by Daniel
+ Colascione <dancol@google.com> back in 1/2018
+ - execute_array_command: function for array_walk to use when executing
+ commands in PROMPT_COMMANDS
+
+doc/{bash.1,bashref.texi}
+ - PROMPT_COMMANDS: new array variable
+
+ 3/24
+ ----
+builtins/ulimit.def
+ - new -R option, for RLIMIT_RTTIME (max time a real-time process can
+ run without blocking). Patch from Maciej Wolny
+ <maciekwolny123@gmail.com> back in 7/2017
+
+doc/{bash.1,bashref.texi}
+ - ulimit: document new -R option
+
+lib/readline/{display.c,rlprivate.h}
+ - _rl_clear_screen: now takes an argument saying whether to attempt to
+ clear the terminal scrollback buffer if the right termcap capability
+ exists
+
+lib/readline/{text.c,readline.h}
+ - rl_clear_display: new bindable command that clears the screen and
+ scrollback buffer
+
+lib/readline/funmap.c
+ - clear-display: new bindable command name
+
+lib/readline/emacs_keymap.c
+ - emacs mode M-C-l now bound to clear-display
+
+doc/bash.1,lib/readline/doc/{readline.3,rluser.texi}
+ - clear-display: document new function and default emacs mode binding
+
+arrayfunc.c
+ - assign_assoc_from_kvlist: allow compound assignments to associative
+ arrays that do not contain words of the form `[key]=value', assume
+ such lists are of the form (key1 value1 key2 value2). A missing or
+ empty key is an error; a missing value is treated as NULL. You
+ cannot mix the two forms. Inspired by a suggestion from Sebastian
+ Gniazdowski <sgniazdowski@gmail.com> back in 7/2019
+
+doc/{bash.1,bashref.texi}
+ - documented new associative array assignment syntax
+
+assoc.[ch]
+ - assoc_to_kvpair: new function that returns a string with quoted
+ key/value pairs from given associative array
+
+array.[ch]
+ - array_to_kvpair: new function that returns a string with quoted
+ key/value pairs from given indexed array (for completeness)
+
+subst.c
+ - parameter_brace_transform: new operator `K': produces the (possibly
+ quoted) value of a variable, except for arrays, where it expands to
+ indexed or associative array assignments in key/value pair form
+ - string_transform,parameter_list_transform: expand `K' to (possibly
+ quoted) values
+ - array_var_assignment: take a new fourth argument saying which kind
+ of assoc assignment statement to produce; calls array_to_kvpair or
+ assoc_to_kvpair as appropriate and just returns that value if
+ necessary without creating a declare command
+ - array_transform: if the operator is `K', call array_var_assignment
+ with new argument that will produce a list of key/value pairs
+
+doc/{bash.1,bashref.texi}
+ - document new 'K' parameter transformation operator

+ - some text and formatting cleanups from Bjarni Ingi Gislason
+ <bjarniig@rhi.hi.is>
+
+bashhist.c
+ - SYSLOG_MAXLEN: increase to 1024, since that seems to be what most
+ syslog daemons handle
+ - bash_syslog_history: if the line is longer than SYSLOG_MAXLEN minus
+ the header length, log it in multiple message with a sequence number
+ instead of truncating. Inspired by a report from
+ <sunhuilin@unionpay.com> back in 7/2018
+
+lib/readline/text.c
+ - rl_activate_mark,rl_deactivate_mark,rl_mark_is_active_p,
+ rl_keep_mark_active: new functions to manage an active region. We
+ don't do anything with an active region yet. Part of a large patch
+ for active regions from Daniel Colascione <dancol@google.com>
+ originally back in 3/2018
+ - rl_clear_screen: call rl_keep_mark_active to keep the region active
+ across the screen refresh
+ - rl_newline: make sure to deactivate the region even though we don't
+ do any redisplay with it yet
+
+lib/readline/readline.h
+ - rl_activate_mark,rl_deactivate_mark,rl_mark_is_active_p,
+ rl_keep_mark_active: new extern function declarations. They are
+ public functions for now
+
+lib/readline/readline.c
+ - readline_internal_setup: make sure the region starts out as not
+ active
+ - readline_internal_charloop: make sure to deactivate the mark after
+ a command, unless the command calls rl_keep_mark_active keep it
+ active
+
+lib/readline/kill.c
+ - rl_bracketed_paste_begin: set rl_mark before inserting the pasted
+ text, so the pasted text defines the region
+ - rl_bracketed_paste_begin: set the region as active after inserting
+ the pasted text
+
+lib/readline/util.c
+ - _rl_abort_internal: make sure we deactivate the region
+
+lib/readline/{terminal.c,rlprivate.h}
+ - _rl_cr: new function to just output the term_cr (or '\r'). Part of
+ the active region patch
+
+lib/readline/display.c
+ - _rl_cr: use where appropriate to replace MSDOS-dependent code and
+ calls to tputs
+
+lib/readline/terminal.c
+ - get and store the terminal sequences to enter and exit standout
+ (usually some background color) mode
+
+ 3/26
+ ----
+subst.[ch]
+ - copy_fifo_list: now returns void *
+ - close_new_fifos: now takes a void * as the first argument, since it's
+ usually the return value from copy_fifo_list
+ - close_new_fifos: (named pipes): cast first argument to a char *,
+ since copy_fifo_list will (someday) return a bitmap
+ - close_new_fifos: (HAVE_DEV_FD): cast first argument to a pid_t *,
+ since it takes a copy of dev_fd_list; use that in the loop to
+ determine whether or not to close file descriptors. First half of
+ fix for bug reported by Valentin Lab <valentin.lab@kalysto.org>
+ - unlink_fifo_list: (named pipes): when compacting the list, make sure
+ to avoid the copy if i == j, and, after copying fifo_list[i] to
+ fifo_list[j], null out fifo_list[i] so we don't try to access it
+ later
+
+execute_cmd.c
+ - execute_command_internal: don't call reap_procsubs after executing
+ the command. Rest of fix for bug reported by Valentin Lab
+ <valentin.lab@kalysto.org>
+ - execute_command_internal,execute_builtin_or_function: ofifo_list is
+ now a void * instead of a char *
