Bash 5.1 is out. "This release fixes several outstanding bugs in bash-5.0 and introducesseveral new features. The most significant change is a return to thebash-4.4 behavior of not performing pathname expansion on a word thatcontains backslashes but does not contain any unquoted globbing specialcharacters. This comes after a long POSIX discussion that resulted in achange to the standard. There are several changes regarding trap handlingwhile reading from the terminal (e.g, for `read' and `select'.) There are anumber of bug fixes, including several bugs that caused the shell tocrash."

The readline library used in bash 5.1 has also been updated to version 8.1. "There are moreimprovements in the programming interface and new user-visible variablesand bindable commands. There are a several new public API functions, butthere should be no incompatible changes to existing APIs."
