v2.4
- acme4j uses the new POST-as-GET method that has been introduced in ACME draft-15. This change is not backward compatible to previous drafts. If you connect to other ACME servers than Let's Encrypt or Pebble, please read the migration guide.
CSRBuilder
now also accepts IP addresses. (It should have in v2.3 already, but I forgot to implement it.)- As announced in v2.3, some deprecated methods have been removed.
I also wrote a short blog article about how acme4j handles POST-as-GET requests.
