FUDforum 2.6.0 was released on 5 January 2004. This release is no longer supported. Please upgrade to FUDforum 3.0.0 ASAP.


RC 1

After about 2 month of development FUDforum 2.6.0RC1 is finally out and hopefully it'll be followed by the final release shortly.

Here are the changes:

  • Removed some unnecessary table locks, that make FUDforum operations faster. This should accelerate browsing for anonymous users quite significantly.
  • Added few SQL engine specific tricks for MySQL & PostgreSQL to gain maximum performance in some complex situations like view rebuilding.
  • Eliminated MySQL specific ENUMS and replaced them with much faster & neater bit masks.
  • Big theme compiler optimization, it is now roughly 4 times faster. Compiling 1 theme on a Celeron 433 takes ~4 seconds versus 15+ seconds before.
  • Updated FUDforum icons. The new icons come from the KDE project, kudos to the designers.
  • Updated the layout to be more compact (thanks to all who helped make it better).
  • Added a new permission setting SEARCH, which allows restriction of searching capabilities.
  • Simplified FUDforum's CSS file, it is now a single file, without any extraneous code, meaning that you can just edit it inside any HTML/CSS editor. The new CSS file also gives you much greater control over the various forum elements.
  • Greatly simplified the PATH_INFO code, the PATH_INFO template is now merely the changed URLs rather the entire copy of default template.
  • Added functionality to the compiler allowing it to use partial templates & message files. Now you can create a theme and only put the changed sections inside it, rather then an entire copy of the theme.
  • Various small bug fixes & tune-ups that did not make it to 2.5.3 release.

P.S. Due to this being a massive change and this being the 1st RC1, if you decide to upgrade an existing forum, be sure to make backups first.

RC 2

This is a fairly small release as far as changes go, the main reason for the release being a fix in the upgrade script that resulted in failure of MySQL 4.0+ installations.

Beyond those changes, there are a number of template changes that remove just about all layout styling from .tmpl files and moving it into the forum.css.tmpl file (this file generated CSS to control FUDforum's layout). This change will empower users to alter the layout far easier and conviniently then before.

Beyond the layout the following fixes were made:

  • Added .htaccess to protect tmp directory in the event is is web browse-able.

RC 3

Yet another release candidate for the RC3 release. A few more fixes this time.


  • Avoid unnecessary work when compiling default theme.
  • Fixed custom theme upgrading.
  • Fixed broken page, when user forces category option in the forum drop down.
  • Check refer before allowing session through. When multi-host sessions are not used validate the session based on IP, Browser & any proxy routes.
  • Added support for cookie sessions.
  • Added the ability to disable message tree views.
  • Implement pager for private messages.
  • Various additional input validation patches.
  • Fixed broken selmsg links in path_info theme.
  • Prefix theme name to backed up files.
  • Updated Chinese translation.
  • Fixed glob() workaround for older PHPs.

RC 4

Various fixes that bring us another step closer to the final release. This release implements a major security hardening fix. Consequently I ask that anyone and everyone try this release and report bugs.


  • Fixed possible bug in sys_id tracking.
  • Added missing include to iemail.inc that causes problems when SMTP is used.
  • Updated German & Chinese translations.
  • Fixed bug in template editor when editing sections with similar names.

  • Added workaround in referrer check for proxies/browsers that mangle HTTP_REFERER.
  • Make referrer checking optional (disabled by default).
  • IP tracking workaround for AOL users, who use AOL browser.
  • Sanitize login/alias names for 0-31 127-159 character ranges.
  • Move admincp above the forum path on message view.
  • Fixed pager in path_info template set.
  • Added missing code bit to mark accounts unapproved on forums where admin needs to approve every new account.
  • When user confirms account and it has not yet been validated by the admin give them a message to indicate why they cannot yet use their account.
  • Incorrect sig options.
  • Uploaded image insertion fix.
  • Corrected possible // in path info URLs.

  • Disallow non A-Za-z0-9_ characters in theme names.
  • Switched from gif to png images for some icons.
  • Fixed a bug during login when anon-user uses PATH_INFO theme and user uses non-PATH_INFO theme.
  • HTML encode description so that it does not break the forum/category editor forms.
  • Added missing continue in file attachment handling inside nntp.inc, which may result in an unterminated loop.
  • Fix htaccess handler for non-apache sapis and add missing return inside installer & upgrade script.
  • Fixed notice warnings inside installer & upgrade script.
  • Better default WWW_ROOT selection for CGI & Fast-CGI installs.
  • Sequence number security mechanism(read more below).

Sequence number security mechanism

To prevent unauthorized requests FUDforum now implements sequence number security mechanism. What this means is that every request is prefixed with a random number that changes every request. Every POST request and GET requests that modify things now validate this number before accepting input. If the sequence number does not equal that of a request prior to the current one, the input is rejected.

RC 5

This is a mini release aimed at addressing several issues resulting directly (and indirectly) from the security hardening in RC4.

The changes are as follows:

  • Make session IP checking optional. (off by default)
  • Corrected admin links on find user page.
  • Corrected links to admin control panels in path_info theme.
  • Make Sequence Key be valid for up to 10 minutes. (this fixes many issues).
  • Fixed category collapsing bug.
  • Fixed download of file attachments where filename contains space(s).
  • Added checks in logout code to prevent permission denied errors when logging out from within a secure forum.
  • Fixed premature clearing of the data inside the sessions table (caused premature logouts).
  • Added an option to allow NNTP e-mail obfuscation when synchronizing FUDforum posts to newsgroups.
