|
|---|
| 6 |
|
|---|
| 7 | This document describes differences between the 5.8.6 release and
|
|---|
| 8 | the 5.8.7 release.
|

| 9 |
|
|---|
| 10 | =head1 Incompatible Changes
|
|---|
| 11 |
|
|---|
| 12 | There are no changes incompatible with 5.8.6.
|

|

| 14 | =head1 Core Enhancements
|
|---|
| 15 |
|
|---|
| 16 | =head2 Unicode Character Database 4.1.0
|
|---|
| 17 |
|
|---|
| 18 | The copy of the Unicode Character Database included in Perl 5.8 has
|
|---|
| 19 | been updated to 4.1.0 from 4.0.1. See
|
|---|
| 20 | L<http://www.unicode.org/versions/Unicode4.1.0/#NotableChanges> for the
|
|---|
| 21 | notable changes.
|
|---|
| 22 |
|
|---|
| 23 | =head2 suidperl less insecure
|
|---|
| 24 |
|
|---|
| 25 | A pair of exploits in C<suidperl> involving debugging code have been closed.
|
|---|
| 26 |
|
|---|
| 27 | For new projects the core perl team strongly recommends that you use
|
|---|
| 28 | dedicated, single purpose security tools such as C<sudo> in preference to
|
|---|
| 29 | C<suidperl>.

|

| 31 | =head2 Optional site customization script
|
|---|
| 32 |
|
|---|
| 33 | The perl interpreter can be built to allow the use of a site customization
|
|---|
| 34 | script. By default this is not enabled, to be consistent with previous perl
|
|---|
| 35 | releases. To use this, add C<-Dusesitecustomize> to the command line flags
|
|---|
| 36 | when running the C<Configure> script. See also L<perlrun/-f>.
|
|---|
| 37 |
|
|---|
| 38 | =head2 C<Config.pm> is now much smaller.
|
|---|
| 39 |
|
|---|
| 40 | C<Config.pm> is now about 3K rather than 32K, with the infrequently used
|
|---|
| 41 | code and C<%Config> values loaded on demand. This is transparent to the
|
|---|
| 42 | programmer, but means that most code will save parsing and loading 29K of
|
|---|
| 43 | script (for example, code that uses C<File::Find>).
