You can also now refer to +user-defined character classes from within other user defined character +classes. +.SH "Modules and Pragmata" +.IX Header "Modules and Pragmata" +.IP \(bu 4 +Carp improved to work nicely with Safe. Carp's message reporting should now +be anomaly free \- it will always print out line number information. +.IP \(bu 4 +CGI upgraded to version 3.05 +.IP \(bu 4 +charnames now avoids clobbering \f(CW$_\fR +.IP \(bu 4 +Digest upgraded to version 1.08 +.IP \(bu 4 +Encode upgraded to version 2.01 +.IP \(bu 4 +FileCache upgraded to version 1.04 +.IP \(bu 4 +libnet upgraded to version 1.19 +.IP \(bu 4 +Pod::Parser upgraded to version 1.28 +.IP \(bu 4 +Pod::Perldoc upgraded to version 3.13 +.IP \(bu 4 +Pod::LaTeX upgraded to version 0.57 +.IP \(bu 4 +Safe now works properly with Carp +.IP \(bu 4 +Scalar-List-Utils upgraded to version 1.14 +.IP \(bu 4 +Shell's documentation has been re-written, and its historical partial +auto-quoting of command arguments can now be disabled. +.IP \(bu 4 +Test upgraded to version 1.25 +.IP \(bu 4 +Test::Harness upgraded to version 2.42 +.IP \(bu 4 +Time::Local upgraded to version 1.10 +.IP \(bu 4 +Unicode::Collate upgraded to version 0.40 +.IP \(bu 4 +Unicode::Normalize upgraded to version 0.30 +.SH "Utility Changes" +.IX Header "Utility Changes" +.SS "Perl's debugger" +.IX Subsection "Perl's debugger" +The debugger can now emulate stepping backwards, by restarting and rerunning +all bar the last command from a saved command history. +.SS h2ph +.IX Subsection "h2ph" +\&\fIh2ph\fR is now able to understand a very limited set of C inline functions +\&\-\- basically, the inline functions that look like CPP macros.

The standard warning still applies; to quote \fIh2ph\fR's +documentation, \fIyou may need to dicker with the files produced\fR. +.SH "Installation and Configuration Improvements" +.IX Header "Installation and Configuration Improvements" +Perl 5.8.5 should build cleanly from source on LynxOS. +.SH "Selected Bug Fixes" +.IX Header "Selected Bug Fixes" +.IP \(bu 4 +The in-place sort optimisation introduced in 5.8.4 had a bug. For example, +in code such as +.Sp +.Vb 1 +\& @a = sort ($b, @a) +.Ve +.Sp +the result would omit the value \f(CW$b\fR. This is now fixed. +.IP \(bu 4 +The optimisation for unnecessary assignments introduced in 5.8.4 could give +spurious warnings. This has been fixed. +.IP \(bu 4 +Perl should now correctly detect and read BOM-marked and (BOMless) UTF\-16 +scripts of either endianness. +.IP \(bu 4 +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. +.IP \(bu 4 +Several obscure bugs involving manipulating Unicode strings with \f(CW\*(C`substr\*(C'\fR have +been fixed. +.IP \(bu 4 +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. +.IP \(bu 4 +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. +.IP \(bu 4 +The internals of the ithreads implementation were not checking if OS-level +thread creation had failed. threads\->\fBcreate()\fR now returns \f(CW\*(C`undef\*(C'\fR in if +thread creation fails instead of crashing perl. +.SH "New or Changed Diagnostics" +.IX Header "New or Changed Diagnostics" +.IP \(bu 4 +Perl \-V has several improvements +.RS 4 +.IP \(bu 4 +correctly outputs local patch names that contain embedded code snippets +or other characters that used to confuse it. +.IP \(bu 4 +arguments to \-V that look like regexps will give multiple lines of output. +.IP \(bu 4 +a trailing colon suppresses the linefeed and ';' terminator, allowing +embedding of queries into shell commands. +.IP \(bu 4 +a leading colon removes the 'name=' part of the response, allowing mapping to +any name. +.RE +.RS 4 +.RE +.IP \(bu 4 +When perl fails to find the specified script, it now outputs a second line +suggesting that the user use the \f(CW\*(C`\-S\*(C'\fR flag: +.Sp +.Vb 3 +\& $ perl5.8.5 missing.pl +\& Can\*(Aqt open perl script "missing.pl": No such file or directory. +\& Use \-S to search $PATH for it. +.Ve +.SH "Changed Internals" +.IX Header "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. +.SH "Known Problems" +.IX Header "Known Problems" +The regression test \fIt/uni/class.t\fR is now performing considerably more +tests, and can take several minutes to run even on a fast machine. +.SH "Platform Specific Problems" +.IX Header "Platform Specific Problems" +This release is known not to build on Windows 95. +.SH "Reporting Bugs" +.IX Header "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. +.PP +If you believe you have an unreported bug, please run the \fBperlbug\fR +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 \f(CW\*(C`perl \-V\*(C'\fR, will be sent off to perlbug@perl.org to be +analysed by the Perl porting team. You can browse and search +the Perl 5 bugs at http://bugs.perl.org/ +.SH "SEE ALSO" +.IX Header "SEE ALSO" +The \fIChanges\fR file for exhaustive details on what changed. +.PP +The \fIINSTALL\fR file for how to build Perl. +.PP +The \fIREADME\fR file for general stuff. +.PP +The \fIArtistic\fR and \fICopying\fR files for copyright information. |
