Today, I saw that the article on how to build your first app has completely changed and no longer uses ZAT. "ZCLI replaces the Zendesk App Tools (ZAT), which are in maintenance mode."
Can I get some more information on what is meant by "Maintenance mode" in this context? Will Zendesk still continue to support apps built on this? If so, for how long? I just spent two weeks learning all about ZAT, only to now find it's not the preferred method and development has been ceased, the day I publish my first app with it. How can I stay ahead of retiring products like this?
