Release Notes: Security fixes were made for the -F option. A regression introduced in 1.4.9b in the "divert" builtin was fixed. The output of the "maketemp" and "mkstemp" builtins is now quoted if a file was created. The "defn" builtin was enhanced to support concatenation of multiple text arguments, as required by POSIX. The "format" builtin was enhanced to parse all C99 floating point numbers. The "index" builtin was enhanced to guarantee linear behavior.
