Download TWiki Release 4.2.0

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.

Release 4.2 is a minor release. TWiki 4.2.0 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.

Release highlights:

  • 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

Known Issues

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

For 4.2.0 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.
