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.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
