Tillitis has always been committed to open source. As we
promised earlier, we continue to be committed to open licenses.

We originally chose “GPLv2-only” as the license for our Verilog and
source code. We are now changing to the more permissive BSD 2-clause
license for all Verilog and source code. The hardware (PCB, PCBA)
license remains the same: CERN Open Hardware License Version 2 –
Strongly Reciprocal.

The full license text is found in each repository, for example in the tkey-device-signer.

The main reason to change the license is to allow more people and
organisations to use our design and our code. This is especially true
for our software libraries, which could not be linked without affecting
the linked code, but also all our other code.

We will start to change the license in our repositories on October
2nd.
