Graham says that the search.cpan.org pod finder hashes on name
The 4 files all thinking they are perldelta.pod confuses it.

We see this as the +lesser of two evils. + +This will only affect people who have a threaded perl 5.8.1, and compiled +modules which use these calls, and now attempt to run the compiled modules +with 5.8.2. The fix is to re-compile and re-install the modules using 5.8.2. + +=head1 Core Enhancements + +=head2 Hash Randomisation + +The hash randomisation introduced with 5.8.1 has been amended. It +transpired that although the implementation introduced in 5.8.1 was source +compatible with 5.8.0, it was not binary compatible in certain cases. 5.8.2 +contains an improved implementation which is both source and binary +compatible with both 5.8.0 and 5.8.1, and remains robust against the form of +attack which prompted the change for 5.8.1. + +We are grateful to the Debian project for their input in this area. +See L<perlsec/"Algorithmic Complexity Attacks"> for the original +rationale behind this change. + +=head2 Threading + +Several memory leaks associated with variables shared between threads +have been fixed. + +=head1 Modules and Pragmata + +=head2 Updated Modules And Pragmata + +The following modules and pragmata have been updated since Perl 5.8.1: + +=over 4 + +=item Devel::PPPort + +=item Digest::MD5 + +=item I18N::LangTags + +=item libnet + +=item MIME::Base64 + +=item Pod::Perldoc + +=item strict + +Documentation improved + +=item Tie::Hash + +Documentation improved + +=item Time::HiRes + +=item Unicode::Collate + +=item Unicode::Normalize + +=item UNIVERSAL + +Documentation improved + +=back + +=head1 Selected Bug Fixes + +Some syntax errors involving unrecognized filetest operators are now handled +correctly by the parser. + +=head1 Changed Internals + +Interpreter initialization is more complete when -DMULTIPLICITY is off. +This should resolve problems with initializing and destroying the Perl +interpreter more than once in a single process. + +=head1 Platform Specific Problems + +Dynamic linker flags have been tweaked for Solaris and OS X, which should +solve problems seen while building some XS modules. + +Bugs in OS/2 sockets and tmpfile have been fixed. + +In OS X C<setreuid> and friends are troublesome - perl will now work +around their problems as best possible. + +=head1 Future Directions + +Starting with 5.8.3 we intend to make more frequent maintenance releases, +with a smaller number of changes in each. The intent is to propagate +bug fixes out to stable releases more rapidly and make upgrading stable +releases less of an upheaval. This should give end users more +flexibility in their choice of upgrade timing, and allow them easier +assessment of the impact of upgrades.

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.
