The 5.3.0 version has now been officially released. It has build number 22.214.171.1242.
You can find it in the official location on our ftp-server.
This version includes the following new features:
In Blaise 5.3.0, the layout language has been added to the system. It is now once again possible to add layout statements to your source code. To make it even more flexible, we offer the possibility to generate the layout statements from the layout designer. This way, you can choose whether you want to program the layout of a questionnaire in the source of the questionnaire, or use the visual layout designer.
Blaise 5.3.0 offers a first version of CARI. It is now possible to record questions, and store the audio files in a database. An example of this functionality can be found in the Samples folder (Samples\Specific Features\CARI).
Blaise 5.3.0 offers a first version of ACASI. This means that it is possible to play audio files in the data entry program(s). The audio files can be stored in the resource database, but urls to audio files can also be used. An example of this functionality can be found in the Samples folder (Samples\Specific Features\ACASI)
Improved MVC version
In Blaise 5.3.0, the MVC data entry program has been improved with respect to the rendering of controls. To guarantee the correct display of controls, a shadow administration all controls and their sizes is maintained. This can have a negative performance impact! The 5.3.0 version of the MVC data entry program now supports right-to-left languages.
Blaise 5.3.0 now supports generic storage (stream and in-depth). This means that you can store data from multiple surveys in the same table of a database.
Disconnected DEP-App, iOS and Android app extension
The apps now support updating changed bmix files and the uploading of audit trail data.
Blaise now offers CATI daybatch access in Manipula.
In addition to these new features, we have solved many small issues.
Our second video tutorial has just been released. It gives a preview of the Layout Language in Blaise 5. This functionality will be available in the official release of Blaise 5.3.0 and we wanted to show how it works.
In the video, you get a brief overview of the syntax of the Layout Language and how you can add it.
We would love your feedback, so don't be shy and leave a comment on YouTube if you can.
A layout section has been reintroduced in the datamodel source. The syntax in this section is similar to the layout section in older versions of Blaise, but not exactly the same. For example, FROM .. TO constructions are no longer allowed, but instructions can now contain parameters, and instructions can be assigned to (local) types. It is not required to use the layout section. It is still possible to define all layout in the Layout Designer, but as soon as the datamodel contains any layout section, existing layout will be overwritten by the layout generated based on the layout sections (as soon as the datamodel is prepared). It will be possible to apply changes to the layout using the Layout Designer and generate the layout statements back into the datamodel, but this will not be fully automatic as comments and conditional defines that might be inside the original layout sections can not be generated. The new sections can be manually reviewed and edited using a wizard before updating.

The Windows DEP in Blaise 5.3.0 now supports CARI (Computer Assisted Recorded Interviewing). CARI enables audio recording during an interview. Which questions will be recorded is highly customizable using a combination of (consent) fields and other configuration settings.
Audio data is AAC encoded in order to optimize the relation between audio quality and storage size. The encoded data is saved in a server side database together with its metadata, including session, fieldname and timing information. Although SQLite is the default database, CARI supports the Blaise General Data Interface allowing you to configure any of the available DBMS.
