The most important fix was made to the v9.5.1 License Server - it has been updated to account for security vulnerabilities. Therefore, users must update their License Server before they can use v9.5.1 client software packages. Please note, this will require users to return all active licenses before uninstalling the v9.5.0 License Server.
Prior to installing the eCognition License Server version 9.5.1 users should return all licenses and uninstall previous versions of the License Server. All 9.5.1 products require the eCognition License Server version 9.5.1 to work.
The eCognition License Server does not support the web interface on Linux distribution CentOS 6 (license server startup script needs to be modified to use -noWeb option for lmadmin).
Please contact support if you have further questions.
