~3 weeks and ~100 commits later and we're just about ready to start the
2.0 RCs. Thanks to everyone using the libraries for their patience
during this process. Our implementation is now (baring bugs :D) in line
with the latest draft specs on the TCG website.

The only issue blocking the RCs from rolling at this point is some TCG
process stuff. We're still waiting for a new version of the TCTI
specification to be released for public review. Once this is done we'll
have one small change to make in the TCTI headers and then we'll kick
off the release process.

In the meantime those packaging and / or using the TSS2 libraries don't
need to wait for the RCs to start before providing any feedback you may
have in advance of the release. Similarly we'll be getting the tools and
tabrmd ready for releases that will make use of the 2.0 version of the
TSS2 libraries.

Regards,
Philip
