Bash 5.0 released

Version 5.0 of the Bash shell has been released.
'The most notable new features are several new shell variables: BASH_ARGV0,
EPOCHSECONDS, and EPOCHREALTIME. The `history' builtin can remove ranges of
history entries and understands negative arguments as offsets from the end
of the history list. There is an option to allow local variables to inherit
the value of a variable with the same name at a preceding scope. There is
a new shell option that, when enabled, causes the shell to attempt to
expand associative array subscripts only once (this is an issue when they
are used in arithmetic expressions). The `globasciiranges' shell option
is now enabled by default; it can be set to off by default at configuration
time.'
