There have been some requests from the customer community that we consider having an 18 month period after the announcement of the release of the full GA version of CA Endevor SCM v18 before support for v17 is dropped. The feeling is that 12 months is not enough time to plan for upgrade with large CA Endevor SCM installs.
I'm pleased to announce that we have taken your suggestion to heart and will be offering a period of 18 months before v17 goes end-of-service after the release of the full GA version of v18.
Thanks as always for your invaluable feedback.
