Hi Micka,
Indeed, Broadcom has a great, up-to-date Product Lifecycle page, but it doesn't seem to address Alain's specific question, likely because these are options or components rather than standalone products. Russell's response covers CA 1 OSI/Common. I couldn't find answers for CA Management Services, but based on this KB, IDMS TP Option for CICS appears to be a subcomponent of IDMS Base. If that's correct, the Product Lifecycle page shows IDMS 18.5 for z/OS went out of support on 31-Dec-2020. This is just based on available information, so I'd recommend checking with someone familiar with these components.
Kind regards,
Tomaz
