+CRITICAL FIX: JAVA HELPER LIBRARY 13.0.0: FIXES CRASH ON UNKNOWN FIELDS IN NESTED API RESPONSES
+
+The Java Helper Library now handles unknown fields gracefully in nested response objects, but if customers are on an affected version, their integration is at risk until they upgrade.
+
+Versions 10.0.0 through 12.1.1 parse nested response types (profile, configuration, webhook, and others) with strict deserialization. When an API response comes back with a field the SDK doesn't recognize, the request fails with ApiConnectionException: Unable to deserialize response: Unrecognized field. Because Twilio APIs can add new optional fields at any time, this is a latent break. Customers’ integrations work today and can start failing without warning the moment a new field ships.
+
+In 13.0.0, the Java Helper Library ignores unknown fields in all response objects, matching how every other Twilio Helper Library already behaves.
+
+What to do
+
+Upgrade to Java Helper Library 13.0.0 or later as soon as possible. Version 13 does include breaking changes so follow the upgrade guide to migrate safely. Once customers are on 13.0.0, their integration handles new optional fields in API responses without hitting deserialization errors.
+
+The Python, Node.js, C#, Ruby, PHP, and Go Helper Libraries are not affected. They already handle unknown response fields the same way.

-NEW REGIONAL IP ADDRESS FOR EVENT STREAMS WEBHOOKS IN US EAST
-
-On September 15, 2026, Twilio is introducing a new regional IP address for Event Streams webhook traffic in US East (us-east-1). This is part of a move from a single shared IP range to dedicated regional addresses, bringing Event Streams in line with how the rest of the Twilio platform routes traffic.
-
-This change only affects customers who validate incoming Event Streams webhook traffic by source IP address. If a setup doesn’t check the source IP, no action is needed.
