Version 5.16.1 (build 4030, dated June 30, 2025) has been released.
It can be found in the usual location on our ftp-server alongside a zip file that contains the stand-alone executables.

New features and changes in this build include a containerized server manager dashboard for cloud use and multifactor authentication (MFA) for the web runtime. We support AMQP (Advanced Message Queuing Protocol) to ensure delivery of server events. Two controls were added to the resource editor: a download control for blob data and QR code control. The resource database also includes two new templates: a download control response value template and an accordion field pane template.

Version 5.15.1 (build 3865, dated December 18, 2024) has been released.
It can be found in the usual location on our ftp-server alongside a zip file that contains the StandAlone executables.

New features and changes for this build include the new multimode dashboard, which now completely replaces the old (CATI) dashboard. It is possible to use the old layout focused on CATI or you can opt to use a newer layout based on multi-mode case management (MMCM). MMCM-related functionalities have been added as well in several parts of the system, e.g. you can now use 'Inherit MMCM' in a datamodel. This will add a special MMCM data block for case management. Furthermore, you can now have two deployment environments, one that uses WCF (the existing protocol) and one that uses REST (the new protocol). If you want to install old packages of web surveys into the REST deployment environment, you first have to reprepare your package. The Blaise Runtime now uses .NET 8.

Please note that we strongly advise NOT using Blaise 4 IS (Web Interviewing) anymore. Due to outdated external libraries and technologies, this version has an increased risk of encountering (data) security issues. Therefore, CBS-Blaise expressly disclaims liability for consequential damages resulting from using Blaise 4 IS.

Version 5.14.1 (build 3642, dated December 13, 2023) has been released.
It can be found in the usual location on our ftp-server alongside a zip file that contains the StandAlone executables.

New features and changes for this build include a first version of the multimode dashboard, next to the old dashboard, which is still available. Manipula has many added settings and an improved performance in four areas.  Performance has been enhanced in several other areas as well, e.g. for record reading using the IDataSet interface of the StatNeth.Blaise.API. This build also offers some CATI improvements, protocols to allow communication using REST instead of WCF, and a fallback mechanism for the data role, session role and audit trail role in the server manager.

Version 5.13.1 (build 3426, dated December 14, 2022) has been released.
It can be found in the usual location on our ftp-server.
New features and changes for this build include several new Manipula functions that can be used to read/update session data and modify data (fields only) as well as some functions that can help with the performance of Manipula under certain conditions. The Dashboard has been extended with a tab that shows Blaise Events. These Events have been added throughout the system and can be used to track everything that happens in the system. A new Event server role will handle these events. The Print functionality now supports pagination and the Appoinment control has been extended to make it possible to add all types of appointments

CMA has been updated to 2.601. It contains many improvements and some important changes. It also includes version 2.0 of the CMA Admin Tool.
