# Depreciation warnings (updated 2022-02-05)

* Provider ACTIVEDIRECTORY_PS is deprecated and will be removed soon. Use MSDNS instead.
* Provider NS1 has no maintainer and is jeopardy of being removed or deactivated if no volunteer steps up soon.
* Call for new volunteers maintainers for CLOUDFLARE_API, GCLOUD, NAMEDOTCOM, ROUTE53, and SOFTLAYER.
* Should we retain Let's Encrypt support?  The "get-certs" command (renews certs via Let's Encrypt) has no maintainer. There are other projects that do a better job. We are considering removing this feature in the future.  See discussion in https://github.com/StackExchange/dnscontrol/issues/1400
