In October I came across a release schedule for CA Single Sign-On. The heading on the document was "CA Single Sign-On (formerly CA Siteminder) Release Schedule". It had release dates for 12.5, 12.51 and 12.52 for all Siteminder products (Policy Server, Agent and Policy Server SDK, Web Agent Option Pack, Web Agents, Secure Proxy Server, APS, Reports Server, Admin UI, and SharePoint Agent) for the remainder of 2014 and through 2015. That document was last updated 10/28/2014. I have not been able to find it again. I was hoping to find a more updated version of it.
