NAME¶

perl52511delta - what is new for perl v5.25.11

DESCRIPTION¶

This document describes differences between the 5.25.10 release and the 5.25.11 release.

If you are upgrading from an earlier release such as 5.25.9, first read perl52510delta, which describes differences between 5.25.9 and 5.25.10.

Notice¶

This release includes two important updates:

• Turning on the removal of "." in @INC
• Providing a warning when "do" is used on a file in "."

Security¶

Modules and Pragmata¶

Diagnostics¶

Configuration and Compilation¶

•

"DEFAULT_INC_EXCLUDES_DOT" has been turned on as default.

Selected Bug Fixes¶

•

" $-{$name} " would leak an "AV" on each access if the regular expression had no named captures. The same applies to access to any hash tied with Tie::Hash::NamedCapture and "all => 1". [perl #130822]

Obituary¶

It is with great sadness we note that Kip Hampton passed away. Probably best known as the author of the Perl & XML column on XML.com, he was a core contributor to AxKit, an XML server platform that became an Apache Foundation project. He was a frequent speaker in the early days at OSCON, and most recently at YAPC::NA in Madison. He was frequently on irc.perl.org as `ubu`, generally in the #axkit-dahut community, the group responsible for YAPC::NA Asheville in 2011.

Kip and his constant contributions to the community will be greatly missed.

Reporting Bugs¶

If you find what you think is a bug, you might check the perl bug database at <https://rt.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 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 "perl -V", will be sent off to perlbug@perl.org to be analysed by the Perl porting team.

If the bug you are reporting has security implications which make it inappropriate to send to a publicly archived mailing list, then see "SECURITY VULNERABILITY CONTACT INFORMATION" in perlsec for details of how to report the issue.
