- Packages - Isolate code used by the CLI into the package `cmd` - (experimental) Add e2e tests for HTTP01, TLS-ALPN-01 and DNS-01, use [Pebble](https://github.com/letsencrypt/pebble) and [challtestsrv](https://github.com/letsencrypt/boulder/tree/master/test/challtestsrv) - Support non-ascii domain name (punnycode) - Check all challenges in a predictable order - No more global exported variables - Archive revoked certificates - Fixes revocation for subdomains and non-ascii domains - Disable pending authorizations - use pointer for RemoteError/ProblemDetails - Poll authz URL instead of challenge URL - The ability for a DNS provider to solve the challenge sequentially - Check all nameservers in a predictable order - Option to disable the complete propagation Requirement - CLI, support for renew with CSR - CLI, add SAN on renew - Add command to list certificates. - Logs every iteration of waiting for the propagation - update DNSimple client - update github.com/miekg/dns
