The FIX-over-TLS (FIXS) Release Candidate 1 was posted for 90 day public review August 31, 2017 and no material feedback raising concerns or issues has been received to date.
The GTC believes the FIXS Technical Specification to be of suitable quality and having achieved fit for purposefulness to be adopted. The GTC has expressed a high level of confidence. Therefore, the FIXS Draft Standard will be in the draft period for six months (January 2018 – June 2018). Two implementations that demonstrate interoperability are needed to move it to Technical Standard - Version 1.0. Potential adopters are strongly encouraged to begin working with the Draft Standard. A FIXS Stunnel User Guide is provided to support implementations.
