No incompatibilities with previous versions are known. + +Visible changes in the shell and its modules since 4.3.5 include the +following: + +The parameter subscripting flag "e", which existed but had limited +usefulness, has been extended to allow reverse matching of strings instead +of patterns. For example, "${array[(ie)*]}" substitutes the index of the +array element that contains the exact string "*". In previous versions of +the shell a fairly hairy process was necessary to ensure pattern characters +were quoted. + +The cd, chdir, pushd and popd builtins now take the option -q (quiet) which +avoids side effects when changing directories, suppressing the effect of +the chpwd function, the chpwd_functions array and printing of the directory +stack. The last was already possible with the option PUSHD_SILENT, but in +previous versions of the shell there was no easy way of suppressing the +other side effects. -- cgit 1.4.1
