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. + +=back + +=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.
