Fixed an out-of-bounds read in the redirection operator completion code. + +b. Fixed execution context so `until continue' doesn't disable execution for + subsequent commands. + +c. Fixed trap handling code so traps don't inherit a command's temporary + environment. + +d. Fixed a bug that resulted in incorrect line numbers when a function is defined + as part of another function's execution. + +e. Fixed a bug in the expansion of ${a[@]} in contexts where word splitting is not + performed and $IFS is not the default. + +f. Fixed a bug that caused ''"$@" to not expand to an empty argument when there are + no positional parameters. + +g. Fixed a bug that caused a shell compiled without job control to use the incorrect + exit status for builtin commands preceded by a command executed from the file + system that causes the shell to call waitpid(). + +h. Improved word completion for quoted strings containing unterminated command + substitutions with embedded double quotes. + +2. Changes to Readline + +a. Fixed a bug that caused mode strings to be displayed incorrectly if the prompt was + shorter than the mode string. + +3. New Features in Bash + +a. Using ${a[@]} or ${a[*]} with an array without any assigned elements when + the nounset option is enabled no longer throws an unbound variable error. + +4. New Features in Readline + +a. New application-callable function: rl_pending_signal(): returns the signal + number of any signal readline has caught but not yet handled. + +b. New application-settable variable: rl_persistent_signal_handlers: if set to a + non-zero value, readline will enable the readline-6.2 signal handler behavior + in callback mode: handlers are installed when rl_callback_handler_install is + called and removed removed when a complete line has been read. + +------------------------------------------------------------------------------ This document details the changes between this version, bash-4.4-beta2, and the previous version, bash-4.4-rc1. |
