That is a step forward. But I'm still missing few features. Most annoying is that there is no way to make multiple changes as one atomic change. From time to time I need to change an A record to a CNAME record. It's not possible without first deleting the A record and then creating the CNAME record. This creates a short window when the record is missing. The NXDOMAIN response can be cashed by recursive resolvers creating temporary outage for some users / whole networks. Unfortunately I'm also unable to change negative TTL for the zone which is set by CF to 1h. For that reason I have to do such changes in the middle of the night and even then I'm nervous doing that for important records.

Very true. Many service without any bold claims like Cloudflare allow you to make multiple changes and press Save/Apply and have an atomic operation. I am also annoyed that many operations are not available in bulk - like seeing the DNSSEC status, enabling it, etc.
