Main new feature is integration of the metadata from BTL Testpackage 20.0. This means you can configure the testplantree with all the tests from TP 20.0. Not all the newly defined or changed testspecification have already be implemented in testscripts though. Missing tests or tests that still need to be changed will be marked at runtime.

We provide the prerelease so our customers have the chance to do verification against their devices in their testing environment. Please provide feedback on any remaining problems, that you might find in the new version so we can eliminate any glitches before the actual release. Please also inform us if everything works well in your testing!

We will provide updated prerelease versions over the next couple of days without extra notice.

Dear BTF customer,

A new version BTF 15.2.0.317 is available for download.

Main new features are:

1. BTF will now be using Python 3.8 for scripting instead of the former Python 2.7 support
   Besides the fact, that we had intended to do the transition for some time now anyways there two urgent reasons to do the transition immediately:
   - Python 2 will no longer be supported by the Python community.
   - Python 2 extensions on Windows can only be compiled with an older version of the Windows development system. But for some of the newer BACnet features we need newer libraries, that only compile with relatively recent versions of the Windows development system.
   
   For customer scripts like prolog, epilog and makefiles we think that in most cases only small adjustments or even no changes will be required. When we learn of common pitfalls in support we will prepare a transition guide for the most typical cases. If you use any third party Python modules or if you have created your own Python modules you need to get versions of these libraries, that are compatible with Python 3.8.

2. Support for BACnet protocol revision 22
   BTF as a device simulator can provide all the objects and properties from BACnet protocol revision 22. From scripts you can read and write all these properties as BACnet client functionality.

3. Support for using testscripts from an official BTL testpackage and tests from addenda or interim testpackages in the same project
   At the moment we support BTL testpackage 15.2 and some of the addenda, that will lead to testpackage 16.
