Hello Nishaat,
I just wanted to clarify that CA Release Automation is not deprecated, we are still actively developing CA RA.
You're welcome to join us next week for a roadmap session to see what the future holds for CA RA, as well as for CA Continuous Delivery Automation. Additional information about the upcoming roadmap sessions can be found under "upcoming events" section in the main page of CA RA community.
Regards,
Nofar Bluestein
Sr. Principal Product Manager, Release Automation.
