Overview

b34 marks as one of the larges released in Flyte 2.0's SDK. It is production ready. Folks have scaled it to tens of thousands of tasks at rapid scale, able to download gigabytes of data and run large scale training on myraid architectures. This release takes us closed to the goal of Flyte 2.0's goals - one platform that is cohesive, simple, consistent, fast and end to end.
At a high level the most notable features are,

1. Serving - serve models, apps using the fast, consistent and simple API. This marks the beta release of the app devex. There will be some more minor changes, but many examples now show that it is possible to invoke services from tasks, tasks from services and services from services.
2. Support for custom context, that goes beyond regular inputs and can pass context data between tasks.
3. Tasks now have docs and description support.

Also welcome many new contributors. Follow the progress for Flyte 2.0 backend in the flyteorg/flyte - v2 branch. Remember as always, all of flyte-sdk can be run locally, so you do not need a backend!
