+
+### Notes
+This release is not backward compatible with the previous versions of Swarm due to the new LocalStore implementation. If you wish to keep your data, you should run a data migration prior to running this version.
+
+BZZ network ID has been updated to 4.
+
+Swarm v0.4.0 introduces major changes to the existing codebase. Among other things, the storage layer has been rewritten to be more modular and flexible in a manner that will accommodate for our future needs. Since Swarm at this point does not provide any storage guarantees, we have made the decision to not impose any migrations on the nodes that we maintain as part of the public test network, nor on our users. We have provided a [manual](https://github.com/ethersphere/swarm/blob/master/docs/Migration-v0.3-to-v0.4.md) for those of you who are running private deployments and would like to migrate your data to the new local storage schema.
