The Trusted Computing Platform Alliance was superseded by the Trusted Computing Group in April 2003. A principal goal of the new consortium was to produce a TPM specification compatible with NGSCB; the previous specification, TPM 1.1 did not meet its requirements. TPM 1.2 was designed for compliance with NGSCB and introduced many features for such platforms. The first TPM 1.2 specification, Revision 62 was released in 2003.
