        * Use -p to do profiling.

+   burden as well.

+3. The new -i option (from xgawk) is used for loading awk library files.
+   This differs from -f in that the first non-option argument is treated

-4. Gawk now supports high precision arithmetic with MPFR.
+4. Gawk now supports high precision arithmetic with MPFR.  The default is
+   still double precision, but setting PREC changes things, or using
+   the -M / --bignum options.  This support is not compiled in if the MPFR
+   library is not available.
 
-5. A number of facilities from xgawk have been merged in!
+5. The dynamic extension interface has been completely redone!  There is
+   now a defined API for C extensions to use.  A C extension acts like
+   a function written in awk, except that it cannot do everything that awk
+   code can. However, this allows interfacing to any facility that is
+   available from C.  This is a major development, see the doc.
 
-6. The dynamic extension interface has been completely redone! See the doc.
+   This support is not compiled in if dynamic loading of shared libraries
+   is not supported.
 
-7. The and(), or() and xor() functions now take any number of arguments,
+   The old extension mechanism is still supported for compatiblity, but
+   it will be removed at the next major release.
+
+6. The and(), or() and xor() functions now take any number of arguments,
    with a minimum of two.
 
-8. New arrays: SYMTAB, FUNCTAB, and PROCINFO["identifiers"]. See the manual.
+7. New arrays: SYMTAB, FUNCTAB, and PROCINFO["identifiers"]. SYMTAB allows
+   indirect access to any defined variable or array; it is possible to

-9. Support for building gawk with a cross compiler has been improved.
