Release Notes: A security issue in "make dist", reported as CVE-2009-4029, was resolved. The new "-g"/"--gnu" command-line option now overrides "-G"/"--traditional", in preparation for not supporting GNU extensions and behaving POSIXly correct without it. The "-L"/"--nesting-limit" command-line option now defaults to 0 for unlimited on platforms that can detect and deal with stack overflow. The "--debugfile" command line option now defaults to stderr. The input engine was optimized for faster processing. Several performance improvements were made. Several portability issues and regressions were resolved.

Release Notes: Security fixes were made for the -F option. A regression introduced in 1.4.9b in the "divert" builtin was fixed.

The "format" builtin was enhanced to parse all C99 floating point numbers. The "index" builtin was enhanced to guarantee linear behavior.
