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

  • Search features have had a few bugs fixed
  • Several bugs related to attaching files have been fixed
  • 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
