+This document details the changes between this version, bash-4.3-release, and
+the previous version, bash-4.3-rc2.
+
+1. Changes to Bash
+
+a. Only Posix-mode shells should exit on an assignment failure in the
+ temporary environment preceding a special builtin. This is how it's been
+ documented.
+
+b. Fixed a bug that caused a failed special builtin to not exit a posix-mode
+ shell if the failing builtin was on the LHS of a && or ||.
+
+c. Changed the handling of unquoted backslashes in regular expressions to be
+ closer to bash-4.2.
+
+d. globstar (**) no longer traverses symbolic links that resolve to
+ directories. This eliminates some duplicate entries.
+
+e. Fixed a bug that caused a SIGCHLD trap handler to not be able to change the
+ SIGCHLD disposition.
+
+f. Fixed a bug that caused a crash when -x was enabled and a command
+ contained a printable multibyte (wide) character.
+
+g. Fixed a bug that caused an interactive shell without line editing enabled
+ to read invalid data after receiving a SIGINT.
+
+h. Fixed a bug that caused command word completion to fail if the directory in
+ $PATH where the completion would be found contained single or double quotes.
+
+i. Fixed a bug that caused a shell with -v enabled to print commands in $()
+ multiple times.
+
+2. Changes to Readline
+
+a. Fixed a bug that caused `undo' to reference freed memory or null pointers.
+
+3. New Features in Bash
+
+a. The [[ -v ]] option now understands array references (foo[1]) and returns
+ success if the referenced element has a value.

+This document details the changes between this version, bash-4.3-rc2, and the
+previous version, bash-4.3-rc1.
+
+1. Changes to Bash
+
+a. Fixed a bug that left variables set by printf -v marked as invisible.
+
+b. Fixed an off-by-one error in a job control warning message.
+
+c. Fixed a bug that caused the shell to crash after declaring a nameref variable
+ without a value.
+
+d. Fixed a bug that caused asynchronous commands to not set $? correctly.
+
+e. Fixed a bug that caused out-of-order execution when executing aliases with
+ embedded newlines containing `.' commands.
+
+f. Fixed a bug that caused error messages generated by expansion errors in
+ `for' commands to have the wrong line number.
+
+g. Fixed a bug that caused the `wait' builtin to not be interruptible in an
+ interactive shell with job control enabled.
+
+h. Fixed a bug that caused SIGINT and SIGQUIT to not be trappable in
+ asynchronous subshell commands.
+
+i. Bash now requires that the value assigned to a nameref variable be a valid
+ shell identifier (variable name or array reference).
+
+j. Converting an existing variable to a nameref variable now turns off the
+ -i/-l/-u/-c attributes.
+
+k. Displaying a nameref variable with `declare -p' now displays the nameref
+ variable and its value rather than following the nameref chain.
+
+l. Fixed a problem with interrupt handling that caused a second and subsequent
+ SIGINT to be ignored by interactive shells.
+
+m. Fixed a bug that caused certain positional parameter and array expansions
+ to mishandle (discard) null positional parameters and array elements.
+
+n. The shell no longer blocks receipt of signals while running trap handlers
+ for those signals, and allows most trap handlers to be run recursively
+ (running trap handlers while a trap handler is executing).
+
+o. The shell now handles backslashes in regular expression arguments to the
+ [[ command's =~ operator slightly differently, resulting in more
+ consistent behavior.
+
+2. Changes to Readline
+
+a. Fixed a bug that could cause readline to crash and seg fault attempting to
+ expand an empty history entry.
+
+b. Fixed a bug that caused a bad entry in the $LS_COLORS variable to abort all
+ color processing but leave color enabled.
+
+c. Fixed a bug that caused display problems with multi-line prompts containing
+ invisible characters on multiple lines.
+
+d. Fixed a bug that caused effects made by undoing changes to a history line to
+ be discarded.
+
+3. New Features in Bash
+
+4. New Features in Readline
+
+a. When creating shared libraries on Mac OS X, the pathname written into the
+ library (install_name) no longer includes the minor version number.

k. New application-settable variable: rl_input_available_hook; function to be

+ input source. The default hook checks rl_instream.

it gets a signal while reading input (read returns -1/EINTR but readline
