## SDK compatibility
Langfuse V3 will not be compatible with JS and Python SDKs versions below 2.0.0. The 1.x.x SDKs use deprecated APIs for inserting tracing data into Langfuse. These APIs depend on synchronous event processing and return the final database state of an object via the API. As Langfuse scales, we now use a queue to process events asynchronously, meaning the final state of an object is not immediately available via the API.

These APIs depend on synchronous event processing and return the final database state of an object via the API. As Langfuse scales, we use a queue to process events asynchronously, meaning the final state of an object is not immediately available via the API. This means that SDKs will break when trying to deserialize the response from the API into an object.
If you are using the 1.x.x SDKs, you must upgrade to the 2.x.x SDKs to use Langfuse V3. You can find the updated SDKs here: [Python](https://pypi.org/project/langfuse/), [JS](https://www.npmjs.com/package/langfuse).
