Breaking changes

Extensions 1.0 framework end of life

OneAgent 1.299 is the last version supporting OneAgent Extensions 1.0 framework. You can continue using OneAgent Extensions 1.0 if you stay at OneAgent version 1.299. Note that this means you'll be using an unsupported Python version 3.8. We strongly recommend migrating your extensions to the latest Extensions 2.0 framework.

For environments with Extensions 1.0, the OneAgent version 1.301 rollout starts after Oct 31, 2024.

For more information, see General guidance and how to migrate .
