We are excited to announce the release of v2.2.0 for wolfTPM. This release adds several new examples such as remote attestation, seal/unseal and GPIO control. There are minor fixes for authenticated sessions. A few coding refactors to improve readability and reliability. We also added endorsement hierarchy support to several examples. If you are using QNX then you will appreciate the built-in HAL SPI driver support.

Fix for using multiple authenticated sessions. Added QNX support. Added new examples for remote attestation (make / activate credential).
