Toby, this is great news! Congratulations!

Why the 54 day delay? Why not open source what you have now? If the reason is only to celebrate the anniversary, that seems a silly reason for maintaining the threat of legal action for activities you now intend to allow. Today, as it happens, is also Reset The Net day <https://www.resetthenet.org/>. Perhaps that could serve as a good enough reason to make the announcement today rather than in 54 days?

In any case, this is awesome news. It may very well change the world. Thanks for this work and this gift to the world!

seL4, a capability-based microkernel whose implementation has been
comprehensively formally verified, is soon to be open source along
with its formal proofs and associated tools.

If you're interested, you can find out more at http://sel4.systems

For those who like academic papers, an overview of seL4 and its
verification is described in the following paper (which I can assure
you is readable without a strong background in formal methods):
