<h2><a name="build_812_monday__jan_10__2005">Build 812 Monday, Jan 10, 2005</a></h2>
<p>Build 812 is based on Perl 5.8.6.</p>
<p><em>Bug Fixes and Changes</em></p>
<ul>
<li>
<p>On Unix, provide a destructor for libperl.  This allows libperl to be
repeatedly loaded and unloaded by e.g. mod_perl without running out of
thread local storage slots.  On Windows this was already handled
correctly.</p>
</li>
<li>
<p>The reloc_perl -a option has been fixed.  It is now possible to relocate
from a shorter to a longer path.</p>

<p>Build 808 is based on Perl 5.8.2.</p>
<p><em>Changes</em></p>
<ul>
<li>
<p>Perl 5.8.2 has been incorporated.  See <a href="../../lib/Pod/perl582delta.html">the perl582delta manpage</a> for a list of
changes.</p>
<p>ActivePerl build 808 is still being compiled with the
<code>-DNO_HASH_SEED</code> option to maintain binary compatibility with earlier
releases.  Perl 5.8.2 implements a new rehashing scheme that will kick
in dynamically based on the actual data being stored in a hash.  This
new scheme is backwards compatible and is enabled in ActivePerl build
808.</p>

<h2><a name="build_807_thursday__nov_6__2003">Build 807 Thursday, Nov 6, 2003</a></h2>
<p>Build 807 is based on Perl 5.8.1.  This is the first release of ActivePerl
based on this new maintenance release of Perl.  This release is meant for
use in production systems.  However, owing to the sheer volume of changes
between Perl 5.8.0 and 5.8.1 that have been incorporated, please be sure
to test it thoroughly in a non-critical environment before you upgrade
your production systems.</p>
<p>Please check <a href="../../lib/Pod/perl581delta.html">the perl581delta manpage</a> for a list of the major changes in Perl.
Only additional changes specific to ActivePerl are mentioned here.</p>
<p><em>Bug Fixes and Changes</em></p>
<ul>
<li>
<p>Perl 5.8.1 has been incorporated.  See <a href="../../lib/Pod/perl581delta.html">the perl581delta manpage</a> for a list of changes.</p>
<p><strong>Important note:</strong> The new <em>Hash Randomization</em> feature has been
disabled in ActivePerl because it is not compatible with Perl 5.8.0.
If we enabled this feature then some modules compiled with 5.8.0 would
not work correctly with 5.8.1 and most modules compiled with 5.8.1
would not work at all with Perl 5.8.0.  This would require maintaining
separate PPM module repositories for 5.8.0 and 5.8.1.</p>
<p>To enable the <em>Hash Randomization</em> feature you must recompile
ActivePerl from source and remove the <code>-DNO_HASH_SEED</code> definition
from the C compiler options.  In that case you must compile all CPAN
modules yourself too because the PPM repository binaries will not be
compatible.</p>
</li>
<li>
<p>Windows 2003 Server is now officially supported.  The installer adds
entries to the IIS6 &quot;Web Services Extensions&quot; list for both &quot;Perl CGI&quot;
and &quot;Perl ISAPI&quot;.  Both are set to &quot;Prohibited&quot; by default and must
be explicitly changed to &quot;Allow&quot; in the IIS Manager.</p>
<p>Win32::GetOSName() detects the release version of Windows 2003
correctly.</p>
</li>
<li>
<p>ActiveState::Rx module has been included.  This module is necessary to
use the Rx Toolkit in ActiveState Visual Perl.  You must upgrade
Visual Perl to version 1.8.1 to use the Rx Toolkit with Perl 5.8.</p>
</li>
<li>
<p>Many bundled modules have been updated to their latest versions:</p>
<pre>
    Archive-Tar-1.07
    Compress-Zlib-1.22
    Data-Dump-1.01
    Digest-MD2-2.03
    Digest-MD5-2.30
    Digest-SHA1-2.06
    File-CounterFile-1.01
    HTML-Parser-3.34
    HTML-Tree-3.18
    URI-1.27
    XML-Parser-2.34
    XML-Simple-2.09
    libwin32-0.21
    libwww-perl-5.75</pre>
<p>In addition, IO::Zlib version 1.01 is now included with ActivePerl.</p>
</li>
</ul>
<p><em>PPM</em></p>
<ul>
<li>
<p>The <em>upgrade</em> command has been fixed.</p>
</li>
<li>
<p>It is now possible to install from a file URL while not being
connected to the Internet.</p>
</li>
<li>
<p>PPM now works on Windows even when the Term::InKey module is
installed.</p>
</li>
</ul>
<p><em>Perl for ISAPI</em></p>
<ul>
<li>
<p>Perl for ISAPI no longer uses line buffering for STDOUT.  This is
especially important for running under IIS6 which bypasses TCP/IP
nagling and directly sends every packet individually.</p>
</li>
<li>
<p>Perl for ISAPI used to close all open file handles before shutting
down the Perl interpreter.  The intention was to prevent file handle
leaks from buggy Perl scripts while running inside the IIS process.
Unfortunately Perl may still execute END blocks or call DESTROY
methods during final destruction and some file handles may get closed
twice in this scenario.</p>
<p>This creates a race condition: the file handle may already have been
re-opened by a different thread before the second close happens.  Perl
then closes a file handle it doesn't own anymore.  This may cause a
different page request to fail.</p>
<p>To avoid this race condition Perl for ISAPI will no longer try to
automatically close open file handles.  Therefore it is possible that
broken Perl applications will now start leaking file handles if they
don't close them correctly themselves.</p>
</li>
</ul>

<h2><a name="build_806_monday__march_31__2003">Build 806 Monday, March 31, 2003</a></h2>
<p><em>Bug Fixes and Changes</em></p>
<ul>
<li>
<p>Several bug fixes and other improvements have been merged from the
Perl development track.  In particular, many of these fixes address
problems in the PerlIO implementation.  See the ActivePerl source
code diff for the complete list of included changes.</p>
</li>
<li>
<p>Other minor bug fixes and documentation updates.</p>
</li>
</ul>
<p><em>PPM</em></p>
<p>PPM has been upgraded to version 3.1.  It fixes most of the known
problems, including:</p>
<ul>
<li>
<p>PPM 3.1 now provides all the functionality of PPM 2.0 and 3.0.
PPM 2.0 is therefore no longer included in ActivePerl 5.8.</p>
</li>
<li>
<p>PPM now works correctly through a proxy server requiring basic
authentication.  Previous versions of PPM 3.0 only supported
proxy servers that did not require authentication.</p>
</li>
<li>
<p>PPM is now more robust in handling user-defined repository URLs.
For instance, URLs with a trailing slash no longer result in
fatal errors.</p>
</li>
<li>
<p>Support for ASPN Perl profiles has been much improved.  However,
at the time of this writing, the ActivePerl 5.8 repositories
do not yet support profiles.  This is expected to become available
shortly.</p>
</li>
<li>
<p>In previous versions of PPM 3, incorrect search results from the
repository (such as package names that do not have corresponding
PPD files) could crash the PPM3 client.  PPM now generates meaningful
error messages under these circumstances.</p>
</li>
</ul>
<p>
</p>
<h2><a name="build_805_thursday__feb_6__2003">Build 805 Thursday, Feb 6, 2003</a></h2>
<p><em>Bug Fixes and Changes</em></p>
<ul>
<li>
<p>Several bug fixes and other improvements have been merged from the
Perl development track.  In particular, many of these fixes address
weaknesses in Unicode support.  See the ActivePerl source code diff
for the complete list of included changes.</p>
</li>
<li>
<p>Bugs in the Perl 5.8 integration of Perl for ISAPI and PerlScript
that resulted in failure to flush output correctly at the termination
of the script have been fixed.</p>
</li>
<li>
<p>On Windows, <a href="../../lib/Pod/perlfunc.html#item_system"><code>system()</code></a> and backticks could return invalid status when
running under environments where the process has to handle Windows
messages.  PerlScript and Perl for ISAPI fall under this category.
The problem has been corrected.</p>
</li>
<li>
<p>On Windows, PerlScript and Perl for ISAPI were affected by a reentrancy
problem, which meant that recursive invocation of these two engines
could fail.  This problem has been corrected.</p>
</li>
<li>
<p>Tk and libwww-perl has been updated to their latest versions.</p>
</li>
<li>
<p>Win32::Shortcut no longer calls <code>CoUninitialize()</code> within an END block.
This avoids random coredumps from this module when its DESTROY methods
happen to get called after the END block executes.</p>
</li>
<li>
<p>PPM v2 and v3 can now optionally generate HTML documentation when
installing packages if POD documentation is found in the package.
This is controlled by the rebuildhtml option in PPM v2 and the
rebuild-html option in PPM v3.</p>
</li>
<li>
<p>Other minor bug fixes and documentation updates.</p>
</li>

<h2><a name="build_804_friday__nov_29__2002">Build 804 Friday, Nov 29, 2002</a></h2>
<p><em>What's new in the 800 Series</em></p>
<ul>
<li>
<p>This build corresponds to the Perl 5.8.0 source code release.</p>
</li>
<li>
<p>The 800 series builds of ActivePerl are not binary compatible with
builds in the 500 or 600 series.  Any extensions built using binaries
from the ActivePerl 500 or 600 series will need to be recompiled.
Note especially that this applies to PPM packages that may have been
built for 500 or 600 series builds.</p>
</li>
<li>
<p>Significant changes that have occurred in the 5.8.0 release
are documented in <a href="../../lib/Pod/perl58delta.html">the perl58delta manpage</a>.</p>
</li>
<li>
<p>Support has been enabled for large file access on all platforms,
meaning that file manipulation facilities within perl can cope with
files larger than 2GB or 4GB.</p>
</li>
<li>
<p>Many new modules are included as a standard part of perl 5.8.0.  See
&quot;Modules and Pragmata&quot; in <a href="../../lib/Pod/perl58delta.html">the perl58delta manpage</a> for a detailed list.
In addition, the Data::Dump module is now included with ActivePerl.
Many other modules have been updated to their latest versions.</p>
</li>
<li>
<p>PPM v3 is now included as the default <code>ppm</code> executable.  PPM v2
continues to be available, and can be executed as <code>ppm2</code>.</p>
</li>
</ul>
