FACTS (5.6.4)
Issues Resolved
- Some performance issues have been resolved resulting in a faster user experience.
Known Issues (Semaphore 5.6.4)
- 15038 - If you attempt to save a Spreadsheet import template, and that template includes the mapping of a Boolean metadata field, then that template will not be usable for later imports.
Stand-alone Linux Publisher (5.6.4)
Note: This applies to the standalone publisher only, not the plugin.
- During the Linux installation you may see a spurious message about setting ACL permissions for the tomcat user. Please ignore these.
Knowledge Model Management (5.6.4)
- When downloading configuration or backup files, it is possible that the default Windows zip extractor will report the downloaded file as invalid. This is, however, likely to be due to long file paths in the zip file not being handled correctly by that extractor. An alternative (such as 7-Zip) should be able to correct extract these files.
Semaphore for SharePoint 2013/2016 Integration (4.0 r54942)
The following are known issues with this version of Semaphore for SharePoint 2013/2016:
- Use of custom hierarchical relationship types for synchronization of models may result in incorrect model information in the term store (“has narrower/has broader” hierarchical relationship synchronization works correctly)
- DE2394 - Classification Server version 4.2.0 won't work when adding in CS URL. An error “Version's parameters must be greater than or equal to zero. Parameter name: revision.” is being shown.
