As always, the manual page (doc/bash.1) is +the place to look for complete descriptions. + +1. New Features in Bash + +a. Added a new `--init-file' invocation argument as a synonym for `--rcfile', + per the new GNU coding standards. + +b. The /dev/tcp and /dev/udp redirections now accept service names as well as + port numbers. + +c. `complete' and `compgen' now take a `-o value' option, which controls some + of the aspects of that compspec. Valid values are: + + default - perform bash default completion if programmable + completion produces no matches + dirnames - perform directory name completion if programmable + completion produces no matches + filenames - tell readline that the compspec produces filenames, + so it can do things like append slashes to + directory names and suppress trailing spaces + +d. A new loadable builtin, realpath, which canonicalizes and expands symlinks + in pathname arguments. + +e. When `set' is called without options, it prints function defintions in a + way that allows them to be reused as input. This affects `declare' and + `declare -p' as well. This only happens when the shell is not in POSIX + mode, since POSIX.2 forbids this behavior. + +f. Bash-2.05 once again honors the current locale setting when processing + ranges within pattern matching bracket expressions (e.g., [A-Z]). + +2. New Features in Readline + +a. The blink timeout for paren matching is now settable by applications, + via the rl_set_paren_blink_timeout() function. + +b. _rl_executing_macro has been renamed to rl_executing_macro, which means + it's now part of the public interface. + +c. Readline has a new variable, rl_readline_state, which is a bitmap that + encapsulates the current state of the library; intended for use by + callbacks and hook functions. + +d. New application-callable function rl_set_prompt(const char *prompt): + expands its prompt string argument and sets rl_prompt to the result. + +e. New application-callable function rl_set_screen_size(int rows, int cols): + public method for applications to set readline's idea of the screen + dimensions. + +f. New function, rl_get_screen_size (int *rows, int *columns), returns + readline's idea of the screen dimensions. + +g. The timeout in rl_gather_tyi (readline keyboard input polling function) + is now settable via a function (rl_set_keyboard_input_timeout()). + +h. Renamed the max_input_history variable to history_max_entries; the old + variable is maintained for backwards compatibility. + +i. The list of characters that separate words for the history tokenizer is + now settable with a variable: history_word_delimiters. The default + value is as before. + +------------------------------------------------------------------------------- This is a terse description of the new features added to bash-2.04 since the release of bash-2.03.
