Deprecation Notice New functionality will only be added to the new libraries (Java 9.x). The old libraries (Java 8.x and below) are deprecated and Twilio will no longer provide bug fixes. Support might ask you to upgrade before debugging issues.
The Twilio Java SDK has undergone significant changes from version 8.x to 9.x — we’ll break down the major changes here to make migrating to the new version as painless as possible. Please head over to our upgrade guide for details. If you’re integrating Twilio in your Java app for the first time, you can skip straight to the installation page. The last version of the Twilio Java SDK to support version Java 8.X is 8.36.0.
