Summarize user-visible core language +enhancements. Particularly prominent performance optimisations could go +here, but most should go in the L</Performance Enhancements> section. -The use of C<(?{ ... })> and C<(??{ ... })> in a pattern disables various -optimisations globally in that pattern. This may or may not be desired by the -programmer. This release adds the C<(*{ ... })> and C<(**{ ... })> -equivalents. The only difference is that they do not and will never disable -any optimisations in the regex engine. This may make them more unstable in the -sense that they may be called more or less times in the future, however the -number of times they execute will truly match how the regex engine functions. -For example, certain types of optimisation are disabled when C<(?{ ... })> is -included in a pattern, so that patterns which are O(N) in normal use become -O(N*N) with a C<(?{ ... })> pattern in them. Switching to C<(*{ ... })> means -the pattern will stay O(N). +[ List each enhancement as a =head2 entry ] -=head1 Modules and Pragmata +=head1 Security -=head2 Updated Modules and Pragmata +XXX Any security-related notices go here.
