-=head1 NAME
-
-perl585delta - what is new for perl v5.8.5
-
-=head1 DESCRIPTION
-
-This document describes differences between the 5.8.4 release and
-the 5.8.5 release.
-
-=head1 Incompatible Changes
-
-There are no changes incompatible with 5.8.4.
-
-=head1 Core Enhancements
-
-Perl's regular expression engine now contains support for matching on the
-intersection of two Unicode character classes. You can also now refer to
-user-defined character classes from within other user defined character
-classes.
-
-=head1 Modules and Pragmata

-=head1 Utility Changes
-
-=head2 Perl's debugger
-
-The debugger can now emulate stepping backwards, by restarting and rerunning
-all bar the last command from a saved command history.
-
-=head2 h2ph
-
-F<h2ph> is now able to understand a very limited set of C inline functions
--- basically, the inline functions that look like CPP macros. This has
-been introduced to deal with some of the headers of the newest versions of
-the glibc. The standard warning still applies; to quote F<h2ph>'s
-documentation, I<you may need to dicker with the files produced>.
-
-=head1 Installation and Configuration Improvements
-
-Perl 5.8.5 should build cleanly from source on LynxOS.
-
-=head1 Selected Bug Fixes
-
-=over 4
-
-=item *
-
-The in-place sort optimisation introduced in 5.8.4 had a bug. For example,
-in code such as
-
- @a = sort ($b, @a)
-
-the result would omit the value $b. This is now fixed.
-
-=item *
-
-The optimisation for unnecessary assignments introduced in 5.8.4 could give
-spurious warnings. This has been fixed.
-
-=item *
-
-Perl should now correctly detect and read BOM-marked and (BOMless) UTF-16
-scripts of either endianness.
-
-=item *
-
-Creating a new thread when weak references exist was buggy, and would often
-cause warnings at interpreter destruction time. The known bug is now fixed.
-
-=item *
-
-Several obscure bugs involving manipulating Unicode strings with C<substr> have
-been fixed.
-
-=item *
-
-Previously if Perl's file globbing function encountered a directory that it
-did not have permission to open it would return immediately, leading to
-unexpected truncation of the list of results. This has been fixed, to be
-consistent with Unix shells' globbing behaviour.
-
-=item *
-
-Thread creation time could vary wildly between identical runs. This was caused
-by a poor hashing algorithm in the thread cloning routines, which has now
-been fixed.
-
-=item *
-
-The internals of the ithreads implementation were not checking if OS-level
-thread creation had failed. threads->create() now returns C<undef> in if
-thread creation fails instead of crashing perl.
-

-
-=head1 New or Changed Diagnostics
-
-=over 4
-
-=item *
-
-Perl -V has several improvements
-
-=over 4
-
-=item *
-
-correctly outputs local patch names that contain embedded code snippets
-or other characters that used to confuse it.
-
-=item *
-
-arguments to -V that look like regexps will give multiple lines of output.
-
-=item *
-
-a trailing colon suppresses the linefeed and ';' terminator, allowing
-embedding of queries into shell commands.
-
-=item *
-
-a leading colon removes the 'name=' part of the response, allowing mapping to
-any name.
-
-=back
-
-=item *
-
-When perl fails to find the specified script, it now outputs a second line
-suggesting that the user use the C<-S> flag:
-
- $ perl5.8.5 missing.pl
- Can't open perl script "missing.pl": No such file or directory.
- Use -S to search $PATH for it.
-
-=back
-
-=head1 Changed Internals
-
-The Unicode character class files used by the regular expression engine are
-now built at build time from the supplied Unicode consortium data files,
-instead of being shipped prebuilt. This makes the compressed Perl source
-tarball about 200K smaller. A side effect is that the layout of files inside
-lib/unicore has changed.
-
-=head1 Known Problems
-
-The regression test F<t/uni/class.t> is now performing considerably more
-tests, and can take several minutes to run even on a fast machine.
-
-=head1 Platform Specific Problems
-
-This release is known not to build on Windows 95.
-
-=head1 Reporting Bugs
-
-If you find what you think is a bug, you might check the articles
-recently posted to the comp.lang.perl.misc newsgroup and the perl
-bug database at http://bugs.perl.org. There may also be
-information at http://www.perl.org, the Perl Home Page.
-
-If you believe you have an unreported bug, please run the B<perlbug>
-program included with your release. Be sure to trim your bug down
-to a tiny but sufficient test case. Your bug report, along with the
-output of C<perl -V>, will be sent off to perlbug@perl.org to be
-analysed by the Perl porting team. You can browse and search
-the Perl 5 bugs at http://bugs.perl.org/
