Note that the exact format and range of long doubles varies:
the most common is the x86 80-bit (64 bits of mantissa) format,
but there are others, with different mantissa and exponent ranges.
-In fact, the type may not be called "long double" at C level, and
-therefore the C<uselongdouble> means "using floating point larger
-than double".

=head1 Coexistence with earlier versions of perl 5
-Perl 5.23.1 is not binary compatible with earlier versions of Perl.
+Perl 5.23.8 is not binary compatible with earlier versions of Perl.
In other words, you will have to recompile your XS modules.
In general, you can usually safely upgrade from one version of Perl
libraries after 5.6.0, but not for executables. TODO?) One convenient
way to do this is by using a separate prefix for each version, such as
- sh Configure -Dprefix=/opt/perl5.23.1
+ sh Configure -Dprefix=/opt/perl5.23.8
-and adding /opt/perl5.23.1/bin to the shell PATH variable. Such users
+and adding /opt/perl5.23.8/bin to the shell PATH variable. Such users
may also wish to add a symbolic link /usr/local/bin/perl so that
scripts can still start with #!/usr/local/bin/perl.

yet.
