The only requirement we have so far is that 14.4.x and newer images must be running on a platform of at least joyent_20141030T081701Z, as that is the platform they are built on. If in the future we move to a newer platform for the builds, we will notify users of this change in the release notes, and ensure that the min_platform requirement is bumped so that it should be impossible to provision on an incompatible platform anyway. As for the reverse, no. There is no need to upgrade images when you upgrade platform, and at no point should backwards incompatible changes be introduced which stops older images from working. A good example of this was the recent OpenSSH work, which thanks to great work from Alex was carefully considered to ensure compatibility with legacy images. You are of course encouraged to keep track with the newer images though, as they will continue to be improved and contain all of the latest security updates and bug fixes. -- Jonathan Perkin - Joyent, Inc. - www.joyent.com ------------------------------------------- smartos-discuss Archives: https://www.listbox.com/member/archive/184463/=now RSS Feed: https://www.listbox.com/member/archive/rss/184463/25769125-55cfbc00 Modify Your Subscription: https://www.listbox.com/member/?member_id=25769125&id_secret=25769125-7688e9fb Powered by Listbox: http://www.listbox.com
