 - **32-bit binaries will no longer be distributed after September 10, 2023.** There is a proposal to stop shipping 32-bit binaries (packages and containers).  If no objections are raised by Sept 10, 2023, new releases will not include them. See https://github.com/StackExchange/dnscontrol/issues/2461 for details.
 - **Call for new volunteer maintainers for NAMEDOTCOM and SOFTLAYER.** These providers have no maintainer. Maintainers respond to PRs and fix bugs in a timely manner, and try to stay on top of protocol changes.
 - **ACME/Let's Encrypt support is frozen and will be removed after December 31, 2022.**  The `get-certs` command (renews certs via Let's Encrypt) has no maintainer. There are other projects that do a better job. If you don't use this feature, please do not start. If you do use this feature, please plan on migrating to something else.  See discussion in [issues/1400](https://github.com/StackExchange/dnscontrol/issues/1400)
