Release Notes

shred/acme4j (org.shredzone.acme4j:acme4j-client)

v4.0.0

• acme4j now requires Java 17 or higher
• A new HttpClient instance was created for every request. Now it is bound to the Session, reducing resource consumption on heavy workloads. (Thanks to @​vincentdo for the PR.)
• A Session instance can now be shared between multiple threads, still keeping track of the correct nonce (Thanks to @​nsheridan for the pointer.)
• draft-ietf-acme-ari is RFC 9773 now
• Updated draft-aaron-acme-profiles-01
• Added support for draft-ietf-acme-dns-account-label (experimental)
• Added Actalis provider
• Removed Buypass provider (they stopped supporting the ACME protocol)
• Increased the default network timeout to 30 seconds, as a few CAs require more response time
• Use the pebbleHost and pebblePort system properties to change the default Pebble host and port
• Updated Pebble TLS certificate
• Removed deprecated methods

The major version bump was mainly caused by the change to Java 17. If you use the dns-01 challenge, you might need to invoke a different method in one place, but besides that, there is probably not much to do on your side. For further information, please read the migration guide.
