That's a great question. For any Singer integrations that we include in the Stitch product, we (Stitch, Inc.) will ensure they stay up to date with the most current version of the API.
That may not be the case with 100% of the community built/ maintained integrations, but our goal with the Singer Slack community and list serve is to connect people using these taps to so that they can validate which are working well and which need additional work.
