Bash 5.3 Released With Many Improvements
Three years since the Bash 5.2 release and one year since the first alpha release, GNU Bash 5.3 was released overnight as the newest step forward for this popular shell used on Linux and other operating systems.
GNU Bash 5.3 introduces a new form of command substitution that executes the command within the current shell execution context. This allows for reading the command substitution's output or to find the result via the "REPLY" shell variable when the command substitution is complete. Bash 5.3 also has been updated for C23 programming language conformance, Readline has added a new option for case-insensitive searching, the GLOBSORT variable can be used to determine how the shell will sort results of pathname completion, and many other changes.
