Hello all,

Today we are submitting some updates to BIP75:

-- Example use cases have been reworded to more accurately describe the goal of this BIP and how the technology works.
-- ECDSA and PGP have been added to the supported public key infrastructure (PKI) types to increase flexibility and use cases.
-- Versioning has been added to make future changes and backwards compatibility easy to manage.
-- Other minor, technical details have been added or changed to improve performance and reduce ambiguity during implementation.

Thank you,
James
