As you've already mentioned, support for character and byte strings is the most important new feature. In connection with localization, there's the Encode module which allows for character set conversions; dollar sign reordering in printf; Locale::Maketext for localized messages; and I18N::Langinfo to query locale data. Another feature is restricted hashes which will replace pseudohashes as the underlying mechanism of fields from perl 5.9: see Hash::Util. Then there's safe signals, of which you've probably heard of. Source filtering, see Filter::Util::Call. Other smaller new features are brackets in prototypes (see perlsub), the new ${^TAINT} variable, newly overridable and tieable builtins, the CLONE function, improved attributes and lvalue functions, loads of new core modules (such as List::Util or Tie::File etc), better bignums, better perlio layers. You may want to read the short Highlights In 5.8.0 section of perl58delta. Update 2006 oct 6: corrected spelling -- thanks to ysth. In reply to Re: Major changes since 5.6.1
