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. +------------------------------------------------------------------------------ This document details the changes between this version, bash-4.3-rc1, and the previous version, bash-4.3-beta2. |
