3 | perldelta - what's new for perl5.006 (as of 5.005_54) |

| 5 | =head1 DESCRIPTION |
| 6 | |
| 7 | This document describes differences between the 5.005 release and this one. |
| 8 | |
| 9 | =head1 Incompatible Changes |

11 | =head2 Perl Source Incompatibilities |
| 12 | |
| 13 | None known at this time. |
| 14 | |
| 15 | =head2 C Source Incompatibilities |

| 19 | =item C<PERL_POLLUTE> |
| 20 | |
| 21 | Release 5.005 grandfathered old global symbol names by providing preprocessor |
| 22 | macros for extension source compatibility. As of release 5.006, these |
| 23 | preprocessor definitions are not available by default. You need to explicitly |
| 24 | compile perl with C<-DPERL_POLLUTE> in order to get these definitions. |
| 25 | |
| 26 | =item C<PL_na> and C<dTHR> Issues |
| 27 | |
| 28 | The C<PL_na> global is now thread local, so a C<dTHR> declaration is needed |
| 29 | in the scope in which it appears. XSUBs should handle this automatically, |
| 30 | but if you have used C<PL_na> in support functions, you either need to |
| 31 | change the C<PL_na> to a local variable (which is recommended), or put in |
| 32 | a C<dTHR>. |

| 36 | =head2 Binary Incompatibilities |
| 37 | |
| 38 | This release is not binary compatible with the 5.005 release and its |
| 39 | maintenance versions. |

69 | =head1 BUGS |
| 70 | |
| 71 | If you find what you think is a bug, you might check the headers of |
| 72 | recently posted articles in the comp.lang.perl.misc newsgroup. |
| 73 | There may also be information at http://www.perl.com/perl/, the Perl |
| 74 | Home Page. |
| 75 | |
| 76 | If you believe you have an unreported bug, please run the B<perlbug> |
| 77 | program included with your release. Make sure you trim your bug down |
| 78 | to a tiny but sufficient test case. Your bug report, along with the |
| 79 | output of C<perl -V>, will be sent off to <F<perlbug@perl.com>> to be |
| 80 | analysed by the Perl porting team. |
