What's New

KnowledgeTree Server 3.6.1

  • Electronic Signatures – this functionality facilitates compliance with a number of standards, including CFR 21 Part 11. When Electronic Signatures is enabled for your system, users are required to enter their KnowledgeTree username and password to complete document and folder write actions where re-authentication is required.
  • Document Type Alerts – these are alerts set up by the KnowledgeTree administrator and applied globally to a specific document type. Users view document type alerts in the document view, as ‘system alerts’.
  • Server-side components for KnowledgeTree Office Add-in are packaged with the KnowledgeTree server stack installer (Commercial only) – the client tool is installed on the client
  • Warning prompt added to the 'Make Immutable' action - previously, users could make a document immutable without realizing that the action could not be undone
  • Improvements to Search – changes to search ranking ensure that results are returned in the correct order, with the document title and metadata ranking higher than content. Improvements to the Advanced Search function ensures that more relevant results are returned
  • Improvements to Indexing – a new, more reliable method of extracting content from documents ensures greater support for document formats and improved cross-platform stability.
  • IE8 compatibility
  • Improved PDF conversion - allows users to generate a PDF of supported file types
  • Improvements to the Upgrade Installers
  • Numerous Bug fixes – listed below


Additionally, the following enhancements, which were first released with KnowledgeTree 3.6-Community Edition, have been added to the KnowledgeTree 3.6.1-Commercial and Community Edition releases:

Known Issues

KnowledgeTree Server

  • Enabling Electronic Signatures in the API prevents connections to the KnowledgeTree server, from KnowledgeTree Tools and the new KnowledgeTree Office Add-in

When no connection can be established to the KnowledgeTree server, KnowledgeTree Tools users and KnowledgeTree Office Add-in users will be unable to use any of the client-side features of the Tools or the Add-in, and they may receive unexpected errors. If you wish to use KnowledgeTree Tools or the KnowledgeTree Office Add-in for desktop integration with the KnowledgeTree server, ensure that the following setting is set to False through KnowledgeTree's web interface, in DMS Administration - System Configuration - Security Settings: Enable API Electronic Signatures. This setting enables and disables electronic signature functionality in the API and for all client tools.

  • Searching for deleted, unarchived documents returns incorrect results

Search criteria isDeleted 'True' and isArchived 'False'. Related call: KTS-4205

  • On Linux, certain file types are downloaded and checked out as a zip archive

This is a Linux issue and not a KnowledgeTree error. On RHEL, when checking out or downloading the following file types, the file is downloaded as a zip archive: docx, pptx, or other Office 2007 files. The file can be successfully checked back in to KnowledgeTree in this format. This issue is found to occur because the mime type magic is detecting the file as a zip file, which it is. Future updates to the mime type database will fix this issue on Linux. Related call: KTS-3623

  • Cross site request forgery and Web-based applications

Be aware that most web-based applications, including KnowledgeTree, may be vulnerable to cross-site-request-forgeries (CSRF). CSRF is entirely different to XSS – whereas CSRF exploits the trust a server places in a user, XSS exploits the trust a user places in the server. CSRF attacks are difficult to determine because the HTTP request containing the attack is sent by a trusted user. To reduce the risk of CSRF attacks, we strongly recommend that KnowledgeTree system administrators familiarize themselves with the issue of CSRF, and take the necessary precautions to protect their KnowledgeTree installations from such attacks.

  • PDF Conversion is not supported for Office 2007 documents

Related call: KTS-4282

  • Bulk download generates a large amount of content in the tmp directory

In certain environments, an issue with the bulk download action causes the generation of a large amount of content in the KnowledgeTree temporary directory. Over an extended period of time the generated content may fill the relevant partition and prevent access to the repository. We have developed a patch to fix this issue.
