The Trusted Computing Group (TCG) has released revisions to multiple specifications:
I wish I knew why WordPress inserts the additional whitespace in these posts…. 😦

PC Client Specific Platform Firmware Profile Specification, Family 2.0, Level 00 Revision 00.21 and Errata
The PC Client Platform Specific Profile for TPM 2.0 systems defines the requirements for platform firmware to initialize and interact with a TPM 2.0 device in a PC Client platform.  This specification should be used in conjunction with the TCG UEFI Protocol Specification Family 2.0, the TCG Physical Presence Interface Specification, and the TCG ACPI Specification to design and implement a PC Client TPM 2.0-enabled platform.  This specification replaces the requirements defined in the PC Client Implementation Specification for Conventional BIOS and the PC Client UEFI Platform Specification for systems with TPM 2.0 devices.

PC Client Work Group EFI Protocol Specification, Family 2.0, Level 00, Revision 00.13
The purpose of this document is to define a standard interface to the TPM on an UEFI platform. It defines data structures and APIs that allow an OS to interact with UEFI firmware to query information important in an early OS boot stage. Such information include: is a TPM present, which PCR banks are active, change active PCR banks, obtain the TCG boot log, extend hashes to PCRs, and append events to the TCG boot log.The latest revision of this specification is written with platforms with TPM 2.0 devices in mind, but nothing in this specification prevents the use with platforms with TPM 1.2 devices.

TCG Storage Opal Test Cases Specification, Version 2.00 Errata Version 1.00, Revision 1.00
The Opal Test Cases Specification contains a set of tests that are intended to verify the correct behavior of a storage device implementing the Opal SSC Specification. These test cases are intended to be used as a basis for the compliance component of the projected Storage certification program, which would seek to ensure a high level of interoperability of storage devices from multiple vendors.

Multiple Stakeholder Model , Revision 3.40
The Multiple Stakeholder Model (MSM) is an informative reference document that describes use cases, recommended capabilities, and various implementation alternatives to allow multiple stakeholders to coexist safely on a mobile platform.  This document includes guidance on how to leverage TCG specifications to realize each alternative.  In particular, this document emphasizes the role of the Trusted Platform Module (TPM), the Mobile Common Profile, and the Mobile Reference Architecture specifications to support these capabilities for multiple stakeholders.  The goal of the MSM is to provide trusted services, for example, TPM and Trusted Network Communications (TNC), in a secure and efficient manner to all interested stakeholders (both local and remote) for a given mobile device. This guidance is applicable to all mobile devices (smartphones, feature phones, basic phones, etc.) and may be useful for other computing devices.  The target audience for this document includes designers, manufacturers, system integrators, application developers, and implementers of Trusted Computing technologies in mobile platforms.

TNC IF-M Segmentation Specification Version 1.0, Revision 5
The Trusted Network Communications (TNC) Work Group defines an open solution architecture that enables network operators to evaluate and enforce policies regarding endpoint integrity when granting access to a network infrastructure. As TCG’s Trusted Network Communications (TNC)-enabled technology is deployed in real-world environments, we’re learning that deplorer’s have the need to collect robust posture information to support endpoint compliance, security automation, and continuous monitoring. IF-M is the communication layer of the TNC architecture used to connect the endpoint components that collect information about the endpoint, and the corresponding components on a policy server that receive that information and act on it. IF-M is designed to be flexible to support communication of virtually any type of information about the endpoint that the enterprise might wish to know.
