<h2><a name="changes211">Geeklog 2.1.1</a></h2>
<p>Geeklog 2.1.1 major new feature is the inclusion of the UIkit framework. It is "a lightweight and modular front-end framework
for developing fast and powerful web interfaces".</p>
<p>This Geeklog release now ships with jQuery v1.11.3, jQuery UI v1.11.4, CKEditor v4.5.4, UIkit v2.24.0, Filemanager v2.2.0, and OAuth class v1.411.</p>
<h3>Major New Features and Improvements</h3>
<ul>
<li>Integrated UIkit framework into Geeklog core.</li>
<li>Support for multiple theme templates with plugins.</li>
<li>Numerous bug and security fixes.</li>
</ul>
<h2><a name="changes210">Geeklog 2.1.0</a></h2>
<p>Geeklog 2.1.0 major new features include and an updated template library and a new advanced editor system. A large number of bugs have also been fixed related to child topics which was introduced in Geeklog 2.0.0.</p>
<p>This Geeklog release now ships with jQuery 1.10.2 and jQuery UI to 1.10.3.</p>
<h3>Major New Features and Improvements</h3>
<ul>
<li>Integrated Caching Template Library original developed by Joe Mucchiello.</li>
<li>Support for themes to specify a default theme.</li>
<li>Added configurable caching support for blocks (regular and gldefault), staticpages and articles.</li>
<li>Speed increases by caching topic tree structure.</li>

<li>Added CKEditor 4.3.2 as the default advanced editor for Geeklog.</li>

<li>Added a File Manager.</li>
</ul>
<h2><a name="changes200">Geeklog 2.0.0</a></h2>
<p><strong>Note:</strong> Geeklog 2.0.0 manages topics differently. Topic
assignments for articles and blocks are now stored in their own database table.
This means the article and block tables have changed slightly. Plugins that
modify blocks directly or have a centerblock may not be compatible with
Geeklog 2.0.0. Please check to see if the plugins you have installed are
compatible before you upgrade. If they are not then disable them if you still
wish to upgrade. We expect most plugin authors to upgrade their plugins to
support Geeklog 2.0.0 soon after the release.</p>
<p>The theme engine has also been updated. Geeklog 2.0.0 introduces
a new function that allows a page to be generated all at once instead of in specific
parts as it was before. Only themes and
plugins that have been updated to use the new function for display can take
advantage of the new features this brings to Geeklog and themes.
</p>
<p>This Geeklog release now ships with jQuery 1.7.2 and jQuery UI 1.8.20.</p>
<h3>New Features and Improvements</h3>
<ul>
<li>Improved strength of password hashing.</li>
<li>Allow Topics to have child Topics.</li>
<li>Allow Articles, Blocks and other Plugin objects to be associated with more than one Topic.</li>
<li>Topic Breadcrumb support.</li>
<li>Emergency Rescue Tool is included with the Geeklog Install.</li>
<li>Added support for MySQLi.</li>
<li>Add Stop Forum Spam and Spam Number of Links Modules to Spam-X.</li>
<li>A new theme called Denim which is based on Responsive Web Design.</li>
<li>A new theme called Modern Curve.</li>
<li>Comments Form on same page as article.</li>
</ul>
<h2><a name="changes182">Geeklog 1.8.2</a></h2>
<p>Geeklog 1.8.2 is a maintenance release. There were no changes in the database, the templates, or the language files in this release, so upgrades should be straightforward.</p>
<h3>Bugfixes</h3>

<li>Fixed Twitter OAuth login.</li>

<h2><a name="changes181">Geeklog 1.8.1</a></h2>
<p>Geeklog 1.8.1 is a maintenance release and a recommended update for all
users of Geeklog 1.8.0. There were no changes in the database, the templates,
or the language files (other than some updated translations) in this release,
so upgrades should be straightforward.</p>
<p>This Geeklog release now ships with jQuery 1.6.3.</p>
<h3>Bugfixes</h3>
<ul>
<li>Fixed information leakage:
<ul>
<li>The "<a href="config.html#desc_rootdebug">rootdebug</a>" option,
when enabled, also dumped the OAuth consumer key and secret. You now
have to additionally set the rootdebug option to "force" to make them
show up in the variable dump.</li>
<li>The MS SQL driver was displaying detailed SQL error messages by
default.</li>
</ul></li>
<li>Fixed a regression in Geeklog 1.8.0 that made the <code>[code]</code> and
<code>[raw]</code> tags not escape content properly.</li>
<li>Fixed some problems with adding and removing elements to/from arrays in
the Configuration.</li>
<li>The admin's User Editor no longer loses changes when an error occured.</li>
<li>Fixed images not being displayed in the story preview (when editing an
existing story).</li>
<li>Plugins can now set <code>$_SCRIPTS</code> in the
<code>plugin_getFooter()</code> function.</li>
<li>Fixed some warnings raised by PHP 5.4.</li>
</ul>
<h2><a name="changes180">Geeklog 1.8.0</a></h2>
<p><strong>Note:</strong> Geeklog 1.8.0 now <strong>requires PHP 5.2.0</strong>
or later. We will provide legacy PHP 4 support for <a
href="#changes1.7.2">Geeklog 1.7.2</a> for a limited time, but would strongly
suggest that you switch to PHP 5.2 or later as soon as possible.</p>
<p>For details, please see the <a href="https://www.geeklog.net/article.php/end-of-php4-support">announcement</a> on the Geeklog homepage.</p>
<h3>New Features and Improvements</h3>
<ul>
<li>Improved Configuration with input validation and a search function. These
improvements were implemented by Akeda Bagus as part of the Google Summer
of Code 2010.</li>
<li>OAuth support, allowing users to log into a Geeklog site with their
Facebook, Twitter, or LinkedIn account. This functionality was originally
developed by Hiroshi Sakuramoto (Hiroron) of Geeklog Japan.</li>
<li>New icons in the default theme (taken from the Tango, Gnome, and Humanity
icon themes).</li>
<li>Ships with <a href="http://jquery.com/">jQuery</a>, which is now the
"official" JavaScript library for Geeklog.</li>
<li>Autotags now have permissions and a description (tooltip).</li>
<li>Revamped Plugins admin panel, which also lets you change the plugin load
order. Plugins can now also indicate dependencies on other plugins.</li>
</ul>
<h2><a id="changes172" name="changes172">Geeklog 1.7.2</a></h2>
<p><strong>Note:</strong> Geeklog 1.7.2 is the last Geeklog version to work on
PHP 4. We will be providing security fixes, if required, for this version until
2012. New features will only be added to Geeklog 1.8.0 and later versions,
which will require at least PHP 5.2.0 to run. Please see <a href="https://www.geeklog.net/article.php/end-of-php4-support">the announcement</a> on geeklog.net
for details.</p>
<h3>Bugfixes</h3>
<ul>
<li>Fixed PostgreSQL support (multiple Geeklog instances sharing one Postgres
database; dbSave function; error reporting; PHP 4 compatibility).</li>
<li>Fixed replacing the <code>[imageX]</code> tags when changing a story id.</li>
<li>Fixed a PHP 4 compatibility issue in the Static Pages plugin.</li>
</ul>
<h2><a name="changes171sr1">Geeklog 1.7.1sr1</a></h2>
<p>This release fixes an XSS in the admin's configuration panel, reported by
Aung Khant of the YGN Ethical Hacker Group.</p>
<h2><a name="changes171">Geeklog 1.7.1</a></h2>
<h3>New Features and Improvements</h3>
<ul>
<li>A Static Page can now be marked as a template and used by other Static
Pages.</li>
<li>Themes can now have their own display functions for the start and end of
blocks.</li>
<li>Please also see the list of <a href="theme.html#changes">theme changes</a>.</li>
</ul>
<h3>Bugfixes</h3>
<ul>
<li>In Geeklog 1.7.0, comment submissions for plugins were missing the type,
i.e. the comments were not recognized as plugin comments.</li>
<li>Changing anything in My Account while Advanced Editor was disabled for the
site also disabled the user's setting for the Advanced Editor.</li>
<li>Fixed the "Show & Hide Boxes" option in My Account.</li>
<li>Reverted a change from Geeklog 1.7.0: Curly braces in block content are not
escaped any longer. To avoid words in curly braces being interpreted as
template variables (e.g. for JavaScript code), add a space after the opening
or before the closing brace.</li>
<li>Reverted a change from Geeklog 1.7.0 that would send a Content-Type header
when calling <code>COM_refresh()</code> since this conflicts with some
plugins (e.g. the Forum).</li>
</ul>
<h2><a name="changes170">Geeklog 1.7.0</a></h2>
<h3>New Features and Improvements</h3>
<ul>
<li>Geeklog now supports <strong>PostgreSQL</strong> databases. This feature
was implemented by Stan Palatnik during the 2009 Google Summer of Code.</li>
<li>When the security token (CSRF protection) expires, the user will now be
asked to <a href="http://wiki.geeklog.net/index.php/Re-Authentication_for_expired_Tokens">authenticate again</a>. On successful re-authentication, the
operation will be repeated and no changes will be lost.</li>
<li>The options to skip spam checks and HTML filtering are now permissions and
no longer restricted to the Root group.</li>
<li>Groups can now be marked as a default group. New users will automatically
be added to all default groups.</li>

user's profile (through a new Plugin API function - requires changes in
plugins).</li>
<li>Pages that require authentication now display a login form.</li>
<li>When the Advanced Editor is enabled for the site, users can now enable or
disable it for themselves in their settings under My Account.</li>
<li>There is now an option to create copies of existing stories (like the
options to copy existing static pages and calendar entries).</li>
<li>A new <code>[user:]</code> autotag is available to easily create links to
a user's profile.</li>
</ul>
<h3>Other changes</h3>
<ul>
<li><strong>Security:</strong> Fixed a vulnerability to dictionary attacks in the
autologin, originally reported by Bookoo of the Nine Situations Group.</li>
<li>The minimum requirements for Geeklog are now <strong>PHP 4.4.0</strong>
and <strong>MySQL 4.0.18</strong>.</li>

<p>This release fixes a vulnerability to dictionary attacks in the autologin,
originally reported by Bookoo of the Nine Situations Group.</p>
<h2><a name="changes161">Geeklog 1.6.1</a></h2>
<h3>New Features and Improvements</h3>
<ul>
<li>Geeklog now lets you enter meta descriptions and meta keywords for the main
page, for stories, topics, static pages, and polls. Please note that these
meta tags <a href="http://www.mattcutts.com/blog/keywords-meta-tag-in-web-search/">may not be used</a> by some search engines.</li>
<li>You can now have one featured story per topic (for stories set to "Show
only in Topic").</li>
<li>New <a href="polls.html#autotags">autotags</a> now allow you to embed polls
in stories and everywhere else where autotags are allowed.</li>
<li>The Migrate option in the install script can now also be applied to an
existing database (i.e. you don't need to import a database dump to update
your URLs and paths).</li>
<li>The Database Backup admin panel now includes options to optimize the
database and convert tables to InnoDB (MySQL only).</li>
<li>Improved <a href="http://wiki.geeklog.net/index.php/Timezone_Support">timezone support</a> and let users actually set their own timezone.</li>
<li>Minor security enhancements:
<ul>
<li>"Important" cookies (like the session cookies) are now created with
the HttpOnly flag set. This will help avoid some XSS attacks,
provided your browser supports this flag.</li>
<li>Template errors will now trigger the <a href="https://www.geeklog.net/faqman/index.php?op=view&t=65">standard error handler</a> instead of
exposing the template path.</li>
<li>Fixed inclusion protection for some of the Spam-X class files.</li>
</ul></li>
</ul>
<p>Please also see the list of <a href="theme.html#changes">theme changes</a>.</p>
<h3>Bugfixes</h3>
<ul>
<li>Fixed automatic <a href="config.html#desc_article_comment_close_enabled">closing of stories for comments</a> after a certain amount of days. If you need to
re-open comments on stories that were closed due to this bug, you can use
this SQL request:<br />
<code style="margin-left:2em">UPDATE gl_stories SET commentcode = 0, comment_expire = 0 WHERE commentcode = 1;</code></li>
<li>The comment speed limit was being ignored.</li>
<li>Fixed a bug in the Group Editor that didn't let you add groups to other
groups (this problem was only introduced in Geeklog 1.6.0).</li>
<li>The admin group for the Static Pages plugin was created with a wrong name
in Geeklog 1.6.0 (fresh installs only).</li>
<li>Several tweaks and minor fixes (e.g. compatibility with PHP 4) in the
search.</li>
</ul>
<h2><a name="changes160sr2">Geeklog 1.6.0sr2</a></h2>
<p>This release addresses the following security issue:</p>
<ul>
<li>Unauthorized file uploads were possible through FCKeditor.<br />
Uploaded files still had to go through FCKeditor's filter, so it was not possible to upload scripts (and the integrity of the Geeklog site as such was not in danger). There were, however, reports that this was used to host malware.<br />
This update prevents use of the upload feature when FCKeditor is disabled and disables it for anonymous users. It also doesn't allow uploading of archive files any more. Furthermore, you need some sort of "edit" permission now to be able to upload files through FCKeditor (this is meant as an interim measure - we will probably introduce a separate "upload" permission in future Geeklog versions).</li>
</ul>
<p>Other fixes:</p>
<ul>
<li>Fixed installation using InnoDB tables.</li>
<li>Fixed a (non-exploitable) SQL error when auto-updating a story's
commentcode field.</li>
<li>Fixed a wrong function name in the Links plugin.</li>
</ul>
<h2><a name="changes160sr1">Geeklog 1.6.0sr1</a></h2>
<p>This release addresses the following security issues:</p>
<ol>
<li>Gerendi Sandor Attila reported an XSS in the forms to email a user and to
email a story to a friend.</li>
<li>The "Mail Story to a Friend" function didn't check story permissions, so
that it was possible to email a story even if you didn't have the
permissions to view it on the site.</li>
</ol>
<p>Other fixes:</p>
<ul>
<li>Fixed an SQL error when submitting a story and the story submission queue
was off.</li>
<li>Fixed calls to a nonexistent function <code>COM_outputMessageAndAbort</code>.</li>
</ul>
<h2><a name="changes160">Geeklog 1.6.0</a></h2>

<li>Site migration support and easier plugin installation, by Matt West</li>
<li>Improved search, by Sami Barakat</li>
<li>Comment moderation and editable comments, by Jared Wenerd</li>
</ul>
<h3>Other changes</h3>
<ul>
<li>The minimum PHP version required by Geeklog is now <strong>PHP 4.3.0</strong>. Given that the PHP team ended support for PHP 4 in August 2008, you should be
looking into upgrading to PHP 5 anyway.</li>
<li>Includes <a href="http://www.fckeditor.net/">FCKeditor</a> 2.6.4.1</li>
<li>Includes a new plugin, <a href="http://wiki.geeklog.net/index.php/XMLSitemap_Plugin">XMLSitemap</a>, that automatically generates a <a
href="http://www.sitemaps.org/">XML sitemap file</a>, as supported by all
major search engines. Plugin written and provided by mystral-kk.</li>
<li>Several <a href="http://wiki.geeklog.net/index.php/New_Plugin_API_Functions_in_Geeklog_1.6.0">new plugin API functions</a> have been added and existing
functions have been extended.</li>
<li>The included documentation has been moved to <span class="tt">docs/english</span> to allow
for translations. Links to the documentation from within Geeklog will link
to existing translations for the current language automatically (or fall
back to the English documentation if no suitable translation can be found).</li>
<li>There were a variety of <a href="theme.html#changes">theme changes</a> to
support new functionality and fix inconsistencies in the layout.</li>
</ul>
<p>This release also includes a number of patches and improvements made by
students applying for participation in the Google Summer of Code 2009. Thank

</ul>
<h2><a name="changes151">Geeklog 1.5.1</a></h2>
<p>Geeklog 1.5.1 is mostly a bugfix release and a recommended upgrade for users
of Geeklog 1.5.0. There were also a few minor feature additions.</p>
<h3>Bugfixes</h3>
<h4>Security related</h4>
<ul>
<li>The upload script for FCKeditor could be <a
href="https://www.geeklog.net/article.php/file-uploads">called directly</a>
to upload various media files (but not executable scripts), as reported
by t0pP8uZz.</li>
<li>The protection in various include files against direct execution did not
work properly on non-case sensitive file systems, e.g. on Windows
(reported by Mark Evans).</li>
<li>It was possible to view stories with a publication date in the future and
stories that had the draft flag set if you knew their story ID.</li>
<li>It was possible to post comments on unpublished stories if you knew their
story ID.</li>
<li>When a database backup fails, the database password is no longer logged to
<span class="tt">error.log</span>.</li>
</ul>

<ul>
<li>All right-side blocks were rendered twice, which not only took more time
than necessary, but could also affect the functionality of add-ons like
the Chatterblock or Shoutbox.</li>
<li>Fixed handling of security tokens (for CSRF protection) that prevented
you from deleting comments on a story that had trackbacks.</li>
<li>Other fixes were applied to the user submission queue, story submissions,
the list of draft stories and the support for MS SQL.</li>
</ul>
<h4>Fixes in the bundled Plugins</h4>

<li>In multi-language setups, blocks can now also be multi-lingual.</li>
<li>New "Subscribe to ..." feed story option when there is a separate feed for
a story's topic.</li>
<li>New option "All Frontpage Stories" for article feeds (skip stories that have
the "Show only in topic" option set).</li>
<li>Allow to unset Configuration options again after they have been "restored",
e.g. after accidental activation.</li>
<li>Configuration options can now be overwritten in <span class="tt">siteconfig.php</span>.
This is mostly useful for the <code>$_CONF['rootdebug']</code> option.</li>
<li>Remotely authenticated users can now use the webservices (they need to use
<span class="tt">username@servicename</span> for their username).<br />
<strong>Note:</strong> OpenID users can <em>not</em> use the webservices,
due to technical issues with the authentication method.</li>
<li>Improved compatibility of the webservices (i.e. AtomPub).</li>
</ul>
<h3>Theme Changes</h3>
<p>There was one mandatory theme change: The template file for configuration
items, <span class="tt">admin/config/config_element.thtml</span> has to be updated (copy
from the Professional theme). All other theme changes in this release are
optional - see the <a href="theme.html#changes">theme documentation</a> for
details.</p>
<h2><a name="changes150">Geeklog 1.5.0</a></h2>
<h3>Results from the Summer of Code</h3>
<p>This release incorporates the following projects implemented during the
the 2007 Google Summer of Code:</p>
<ul>
<li>New user-friendly install script by Matt West</li>
<li>New Configuration GUI (replacing config.php) by Aaron Blankstein</li>
<li>New Webservices API based on the Atom Publishing Protocol by Ramnath R. Iyer</li>
</ul>
<h3>Other New Features and Improvements</h3>

<li>The Links plugin now has hierarchical (sub-)categories.</li>
<li>Updated <a href="http://www.fckeditor.net/">FCKeditor</a> to version 2.6.</li>

finally resolve all outstanding issues with the handling of special
characters, HTML entities, etc. in stories. Also introduces a new
<code>[raw]</code> tag as an inline complement to <code>[code]</code> when
you want to post pieces of code (e.g. HTML) "as is", so that they are not
interpreted.</li>
<li>Comments can now be closed, i.e. existing comments will still be displayed
but no new comment can be posted.</li>
<li>The Polls plugin now allows for multiple questions per poll.</li>
<li>The Static Pages plugin now supports comments.</li>
<li>The database backup admin panel now lets you delete and download
backups.</li>
<li>The default Professional theme is now HTML 4.01 Strict compliant. Geeklog

compliant theme).</li>
</ul>
<h3>Security</h3>
<ul>
<li>Geeklog now includes protection against <a href="https://www.geeklog.net/article.php/csrf">cross-site request forgery</a> attacks.</li>
<li>Lukasz Pilorz reported <a href="https://www.geeklog.net/article.php/kses">security issues in kses</a>, the HTML filter we're using in Geeklog.</li>
</ul>
<h2><a name="changes141">Geeklog 1.4.1</a></h2>
<h3>New Features</h3>
<ul>
<li>Support for Microsoft SQL Server. Starting with this release, Geeklog can
now also be installed on Microsoft SQL Server, so it's no longer restricted
to just MySQL. The MS SQL support was developed by Randy Kolenko.
Thanks, Randy!<br />
Please note that any third-party plugins will have to offer support for
MS SQL before they can be installed on Microsoft SQL Server. The bundled
plugins (Calendar, Links, Polls, Spam-X, Static Pages) have already been
updated accordingly.</li>
<li><a href="calendar.html">Calendar plugin</a>. The formerly built-in calendar
and events have now been moved into a separate plugin. This complements the
move of the <a href="polls.html">polls</a> and <a href="links.html">links</a> sections into plugins in Geeklog 1.4.0 and makes Geeklog more modular as you
can now easily disable or replace functionality that you don't need for
your site.</li>
<li><a href="http://wiki.geeklog.net/wiki/index.php/Multi-Language_Support">Multi-language support</a>. It is now possible to build truly multi-lingual sites
with Geeklog where not only the navigation but also the content of the site
changes with the language.</li>
<li>Ships with <a href="http://www.fckeditor.net/">FCKeditor</a> 2.3.1, which once
again includes a file manager for uploading images.</li>
<li>A function for mass-deletion of old or inactive users. The list automatically
searches for users that have never logged in, only used the site for a very
short time or have not been online since a very long time. The time span can
be varied, and found users can be selectively deleted.</li>
</ul>
<h3>Security</h3>
<p>In the light of the security issues discovered in Geeklog 1.4.0 and earlier
versions, the Geeklog source code has undergone a code review. We have
identified and addressed several minor issues and introduced new measures to
enhance security in this release. As a welcome side effect, the code reviews
have also uncovered a few bugs and inconsistencies that we also fixed in this
release.</p>
<h3>Spam Protection</h3>
<p>With this release we are finally removing support for the <a href="https://www.geeklog.net/article.php/mt-blacklist-discontinued">discontinued</a> MT-Blacklist. In its place, we are now using a system called Spam Link Verification (SLV) run by Russ Jones at <a href="http://www.linksleeve.org/">www.linksleeve.org</a>. SLV could be described as a community-driven, automatically updated blacklist. See the documentation of the <a href="spamx.html" rel="nofollow">Spam-X plugin</a> for details.</p>

<h2><a name="changes140sr4">Geeklog 1.4.0sr4</a></h2>
<p>Two exploits have been released by "rgod" for insecure Geeklog installations and for a bug in the "mcpuk" file manager that we've been shipping as part of FCKeditor in all previous 1.4.0 releases.</p>
<ul>
<li>Some of the files outside of the public_html directory were not protected
against direct execution. If Geeklog was installed such that those files
were accessible from a URL (which has always been strongly discouraged in
the installation instructions) then those files could be used to load and
execute malicious code from a remote server.
<br /><br />
More information: <a
href="https://www.geeklog.net/article.php/so-called-exploit">So-called
Geeklog "exploit" posted</a>
<br /><br />
In this release, we've added the missing execution prevention for all files
outside of public_html. We would still, however, suggest that you fix your
Geeklog install if the files outside of public_html are accessible from a
URL (see our <a
href="https://www.geeklog.net/faqman/index.php?op=view&t=56">FAQ</a> for
details).
</li>
<li>The "mcpuk" file manager that we've integrated into FCKeditor allowed the
upload of arbitrary PHP code (even if FCKeditor was disabled in Geeklog's
config.php). Depending on your webserver's configuration, it was then
possible to execute that uploaded code.
<br /><br />
More information: <a href="https://www.geeklog.net/article.php/exploit-for-fckeditor-filemanager">Exploit for FCKeditor's mcpuk file manager</a>
<br /><br />
The file manager has been removed from this release. You will therefore no
longer be able to upload files, e.g. images, through FCKeditor. Future
versions of Geeklog will ship with an updated version of FCKeditor and its
included file manager.
</li>
</ul>
<p>Note: This release also includes the <a

lib-trackback.php</a> for better protection against Trackback spam.</p>

<h2><a name="changes140">Geeklog 1.4.0</a></h2>
<p><small>(Geeklog 1.4.0 was originally supposed to be called 1.3.12, so any
references you may find to a version 1.3.12 apply to version 1.4.0)</small></p>
<h3>New Features</h3>
<ul>
<li>Geeklog now officially works with <code>register_globals = off</code>.
Please note that some plugins may still require it to be <code>on</code>,
though.</li>
<li>Added support for sending and receiving <a
href="http://en.wikipedia.org/wiki/Trackback">Trackback</a> and <a
href="http://en.wikipedia.org/wiki/Pingback">Pingback</a> comments. Both
are supported for stories, but there is also a new plugin API so that
plugins can use this feature, too. Trackback and Pingback can be disabled
in <span class="tt">config.php</span>.</li>
<li>Added the ability to "ping" weblog directory services to advertise site
updates (preconfigured to ping <a
href="http://pingomatic.com">Ping-o-Matic</a>). As with Trackback and
Pingback, this is supported for stories, but plugins can also make use of
this feature via the plugin API.</li>
<li>New syndication framework so that Geeklog can now <strong>read and
write</strong> feeds in different formats (currently supported: RSS, RDF,
and Atom).</li>
<li>New administrator controlled user status. Including banning and
administrator activation of accounts.</li>
<li>New Remote Authentication system to allow people with accounts on remote
services such as Blogger.com or LiveJournal.com to login to your site
without having to directly register on your site. (Remote accounts can be
banned as normal accounts).</li>
<li>The Admin sections have been revamped to provide a more consistent look and
sortable lists. "Command and Control" (<span class="tt">moderation.php</span>) now also
comes with a new set of icons and has one icon for every Admin section.
Furthermore, the Admin block and Command and Control can be <a
href="config.html#desc_sort_admin">sorted</a> alphabetically.</li>
<li>Ships with <a href="http://www.fckeditor.net/">FCKeditor</a> (WYSIWYG
editor). To <a href="config.html#desc_advanced_editor">enable</a>, set
<code>$_CONF['advanced_editor'] = true;</code> in your
<span class="tt">config.php</span>.</li>
<li>The search now only displays a specified amount of results per page to
avoid running into timeouts when searching through large databases.<br />
<strong>Note:</strong> Plugins will have to be updated to support the "paged" search.
Until then, Geeklog fakes the paged results for plugin searches, which
means that a plugin that hasn't been updated will still search through the
entire database, but Geeklog will only display the results for the current
result page.</li>
<li>Introduced an "Article Directory", providing an overview of all past
articles, sorted by year and month.</li>
<li>The default permissions for new objects (stories, topics, blocks, etc.) can
now be set in config.php.</li>
</ul>
<h3>Compatibility</h3>
<ul>
<li>Due to the changes, themes will have to be updated to work with Geeklog
1.4.0. See the <a href="theme.html#changes">list of theme changes</a> for
details.</li>
<li>The plugin API for comments has changed. Plugins using comments will have
to be updated to work with Geeklog 1.4.0.</li>
</ul>

<p>This release addresses the following security issues:</p>

stories even if you did not have access to those stories
(reported by LWC). The same problem also existed with poll comments.</li>
<li>Supplying an illegal start or end date to the advanced search resulted in a
warning message that disclosed the path to the Geeklog install on the
server (reported by r0t3d3Vil).<br />
It was <strong>not</strong> possible to use this for SQL injections.</li>
</ol>
<p>Also included in this release are bugfixes, e.g. for the problems editing
static pages when URL rewriting was enabled, that were introduced in
1.3.11sr2.</p>
<h2><a name="changes1311sr2">Geeklog 1.3.11sr2</a></h2>
<p>This release provides security enhancements and better spam protection
originally developed for Geeklog 1.3.12. It also addresses a few bugs where
the bugfix could be integrated with a reasonable amount of work (other bugfixes
will have to wait for the 1.3.12 release).</p>
<h3>Security and Spam protection</h3>
<ul>
<li>There is now a speed limit for login attempts, defaulting to three tries
in a five minute period (<a
href="config.html#desc_login_attempts">configurable</a> in
<span class="tt">config.php</span>).</li>
<li>Linefeeds are filtered from the To:, From:, and Subject: fields of any
email sent through <code>COM_mail</code>.</li>
<li>When a new user account is created and the user submission queue is enabled
in <span class="tt">config.php</span>, Geeklog now ensures that the new account is properly
queued even in the unlikely event that the account creation fails halfway
through.</li>
<li>When a post is identified as spam, it now also triggers the speed limit
(ie. posters will have to wait for the speed limit to expire before they
can make another submission).</li>
<li>Spam posts now get a 403 "Forbidden" HTTP response code.</li>
<li>Spam checks are now done for comments, story, link, and event submissions,
the message sent with the "email story to a friend" option, and for the
contents of the user profile.</li>
<li><a href="https://www.geeklog.net/article.php/spam-x-1.0.2"
rel="nofollow">Spam-X plugin 1.0.2</a> included.</li>
</ul>
<p>Please note that MT-Blacklist (used by Spam-X) has recently been <a href="https://www.geeklog.net/article.php/mt-blacklist-discontinued">discontinued</a>. The
Spam-X plugin as included in this release is configured to get the last version
of the blacklist from geeklog.net, but there will be no more updates.</p>
<h3>Bugfixes</h3>
<ul>
<li>Fixed an error message thrown up by PHP 5.0.5 or later when viewing the
article page (bug #483).</li>
<li>Quote names in email addresses as soon as they contain any non-alphanumeric
characters, apart from the blank (bug #368). This should help when trying
to email users with special characters in their name.</li>
<li>Upgraded included kses class to version 0.2.2 which fixes problems with
Japanese and Thai characters (bugs #94 and #119).</li>
<li>Fixed SQL error when using the [staticpage:] autotag (bug #373).</li>
</ul>
<p>For a complete list of bugfixes, please see the Changelog.</p>
<h3>Improvements</h3>
<ul>
<li>Added support for a <code>custom_usercheck</code> function (for the
custom registration code). See the included <span class="tt">lib-custom.php</span> for
details.</li>
<li>Improved handling of the auto-archive option in <span class="tt">index.php</span>, which
should slightly improve page load times.</li>
<li>Includes several new and updated language files.</li>
<li>Includes updated PEAR classes.</li>
</ul>
<h2><a name="changes1311sr1">Geeklog 1.3.11sr1</a></h2>
<p>This release addresses the following security issue:</p>
<ul>
<li>Stefan Esser found an SQL injection that can, under certain circumstances,
be exploited to extract user data such as the user's password hash.</li>
</ul>
<h2><a name="changes1311">Geeklog 1.3.11</a></h2>
<p>Geeklog 1.3.11 is a <strong>bugfix and security release</strong> over Geeklog 1.3.10 and is meant to replace 1.3.10. The change in the version number was necessary since one of the bugfixes involves a change in the database.</p>
<h3>Security issues</h3>
<ol>
<li>It was possible to submit stories anonymously even if anonymous submissions
were turned off in <span class="tt">config.php</span> (reported by Barry Wong).<br />
These stories still ended up in the submission queue, though, unless you
disabled it in <span class="tt">config.php</span>.</li>
<li>Some of the parameters in link and event submissions weren't filtered,
leaving them open to potential SQL injections.</li>
<li>The links for the What's Related block were created from the unfiltered
story text, opening the possibility of XSS attacks (reported by Vincent
Furia).</li>
</ol>
<h3>Bugfixes</h3>
<ul>
<li>Fixes the length of the 'sid' field in the gl_comments table. Using story
IDs longer than 20 characters prevented comment posts from being associated
with the story.</li>
<li>Ensures compatibility with PHP 4.1.x (includes updated PEAR packages).</li>
<li>Fixes the archiving option being activated too early (bug #345).</li>
<li>Properly deletes comments and story images when deleting entire topics
(bug #339).</li>
<li>Deletes comments when deleting polls.</li>
<li>Fixes several bugs in the calendar and improves overall handling of both
the site calendar and the personal calendars (bugs #268, #336, #338, and
others).</li>
