Bash 4.4 and Readline 7.0 released
The GNU Bourne Again SHell
(Bash) project has released version 4.4 of the tool. It comes with a large
number of bug fixes as well as new features:"The most notable new
features are mapfile's ability to use an arbitrary
record delimiter; a --help option available for nearly all builtins; a
new family of ${parameter@spec} expansions that transform the value of
`parameter'; the `local' builtin's ability to save and restore the state
of the single-letter shell option flags around function calls; a new
EXECIGNORE variable, which adds the ability to specify names that should
be ignored when searching for commands; and the beginning of an SDK for
loadable builtins, which consists of a set of headers and a Makefile
fragment that can be included in projects wishing to build their own
loadable builtins, augmented by support for a BASH_LOADABLES_PATH variable
that defines a search path for builtins loaded with `enable -f'. The existing
loadable builtin examples are now installed by default with `make
install'." In addition, the related Readline
command-line editing library project has released Readline 7.0.
