Important Note
This release does not contain announced user features but contains architectural changes to support upcoming new features. We have strived to keep changes backward compatible so there should be no breaking changes apart from the following:
- If you used `METAFLOW_` environment variables to pass top-level options for flow-decorators (like `METAFLOW_BRANCH` to pass the equivalent of `--branch` for the project decorator), you will now have to use `METAFLOW_FLOW_` (so `METAFLOW_BRANCH` is now `METAFLOW_FLOW_BRANCH`). The reason for this change was to more safely scope flow-level decorator options.
- If you implement your own extensions (and specifically step/flow decorators), you should move any code you may have in `__init__` to a new callback hook called `init` (no argument). Failure to do so should not impact current functionality but may prevent your decorator from taking advantage of upcoming changes.
We are not aware of any other user-visible breaking changes but please come ask us (or file an issue) if you notice other regressions.
