You will either need to wait for the updates to be made available, or look at removing them (with or without replacing them with other ways to do what they do). The JIRA suite utilities will need a paid update (which is available already)
It varies, and you'd need to contact the vendors.
Generally, a lot of vendors try to be pro-active and try to look at upgrades when the Early Access versions become available and the "what developers need to know about version x" docs are published. But in many cases, there's not enough time, or confidence that the APIs are stable, so the efforts don't really start until a few days before the release when we do know they'll be stable. It can take a while, and without asking a vendor directly, there's no real way to know what their plans are. Sometimes, you're going to run into a "never", although I don't think there are any of those on your list.
