v5.0.0
CHANGES:
- IPv6 support for client and server (Mirage, Unix, Lwt) (#249 #252 @hannesm)
This results in breaking changes, especially in the Mirage boilerplate,
since now a Mirage_stack.V4V6 is needed instead of a Mirage_stack.V4. - dns-certify: support EC private keys, now that X509 0.12.0 supports them
