Download TWiki Release 4.2.4

TWiki is a flexible, powerful, and easy to use enterprise collaboration platform. It is a Structured Wiki which can be used to run a project development space, a document management system, a knowledge base, or any other groupware tool, on an intranet or on the internet.

TWiki 4.2.0 was released January 2008 and introduced some hot new features that make TWiki a better user experience for both beginners and experienced application developers. It also contained quite a number of bugfixes since 4.1.2.

TWiki 4.2.1 is a patch release which only contains bug fixes. More than 150 bugs have been fixed since the release of 4.2.0 in all areas of TWiki.

TWiki 4.2.2 is a patch release which only contains bug fixes. About 10 bugs have been fixed since the release of 4.2.1 in all areas of TWiki.

TWiki 4.2.3 is a patch release containing only the configure script as a security fix for TWiki:Codev.SecurityAlert-CVE-2008-3195.

TWiki 4.2.4 is a patch release which only contains over 30 bug fixes. This release also has a security fix for TWiki:Codev.SecurityAlert-CVE-2008-5304 and TWiki:Codev.SecurityAlert-CVE-2008-5305

It is highly recommended to upgrade TWiki 4.2.x to 4.2.4. Users will find the 4.2.4 much more stable and safe in daily use.

4.2 Release highlights:

TWiki 4.2 adds a completely new WYSIWYG editor which looks set to take the popular enterprise wiki into wider markets. The WYSIWYG editing makes TWiki much more appealing to users outside TWiki's traditional IT and engineering user base.

  • WYSIWYG editor - a completely new, simple to use editor that virtually eliminates the need for training and promotes faster and more inclusive take up of the wiki within the organization.
  • SQL style query language for programmable search
  • New restore feature allows for easier rollback and policing of page changes/edits
  • Installation enhancements to make installation and upgrades easier
  • Improved login name/wiki name mapping to enable easier integration with external authentication mechanisms, such as LDAP
  • Improved plugins API

4.2.1 Bugfix Highlights

  • Much more stable Wysiwyg editor
    • Better support for non-English characters
    • Better handling of bullet points
    • Pickaxe feature which enables quick swap between Wysiwyg and raw edit is more stable
    • Attachment of files within Wysiwyg editor working better
    • Linking feature fixed
  • More stable EditTablePlugin
  • Better support for UTF8 though UTF8 is still regarded as experimental and features such as wiki words do not work with non-english characters. UTF8 will be a good choice for languages such as Chinese, Japanese and Korean
  • Better support for non English charsets
  • Easier configuration of language settings in configure
  • Renaming of webs much improved
  • Compatibility with perl 5.10
  • Fixes related to mandatory fields in forms

  • Some cross site scripting possibilities have been eliminated
  • Plugins that uses beforeAttachmentSaveHandler now works stable (e.g. BlackListPlugin)
  • The feature of having RCS files (the ,v file) in a separate directory never worked. Feature has now been removed as it really does not give any advantages.
  • User mapping feature improved to ensure 1:1 mapping between canonical user ID and login ID which is important for security

4.2.2 Bugfix Highlights

  • Registration with verification fails in 4.2.1
  • REVINFO with web specified in topic param renders as though topic does not exist.
  • TWiki::Compatibility has undefined variable error

4.2.3 Bugfix Highlights

4.2.4 Bugfix Highlights

  • SecurityAlert-CVE-2008-5305 - TWiki SEARCH variable allows arbitrary shell command execution
  • SecurityAlert-CVE-2008-5304 - Cross-site scripting vulnerability with TWiki URLPARAM variable

Additional Downloads of TWiki

Various third party providers make special packaged versions of TWiki available for download. ALERT! Note - not all these are the latest version of TWiki.

Upgrading From TWiki-4.1.x

Significant changes has been made since 4.1.2 so upgrading cannot be done by applying a patch.

The upgrade can be done relatively easily by following the the procedure described on TWikiUpgradeGuide.

Upgrading From TWiki-4.2.0

TWiki 4.2.4 has a significant number of changes compared to previous 4.2.x releases so it is not feasible to provide a download file with only the changed files.

Instead we have provided upgrade packages where the most common tailored files are omitted. Most people will be able to copy these files on top of a running 4.2.x (always take a backup). It is recommended to regenerate the lib/LocalSite.cfg by renaming it as a backup and re-running configure which will create a new LocalSite.cfg. You can use your backup to remember your old settings.

Note that TWiki.TWikiPreferences will be overwritten by the upgrade package as it contains an important update. If you have changed TWiki.TWikiPreferences (which we advice not to do, instead copy the settings to Main.TWikiPreferences) make sure to save a copy before applying the upgrade.

The upgrades are cumulative, that is, the 4.2.4 upgrade includes the 4.2.1 - 4.2.3 changes. You do not need to apply one by one.

The TWikiReleaseNotes04x02 contains additional information for the upgrader.

Known Issues

After a new release the more annoying bugs are listed at Known issues. If possible work arounds are provided.

For 4.2 especially the new Wysiwyg editor is a complex new feature and bugs will be found as people start using it. You do not need to wait for next release of TWiki to upgrade the Wysiwyg editor. We are continuously fixing it and uploading new versions in the Plugins web here on twiki.org.

Using configure it takes few minutes to upgrade the two plugins that make up the Wysiwyg editor: WysiwygPlugin and TinyMCEPlugin. It is recommended to check for updates right after installing TWiki and check for upgrades regularly. See HowToUpgradeExtensionsWithConfigure for a step by step guide that shows how simple it is to upgrade using configure.
