+
+#### Upgrading notices
+
+##### Configuration changes
+
+There are no configuration changes for this release.
+
+##### REST API
+
+No changes.
+
+##### Pinning Service API
+
+No changes.
+
+##### IPFS Proxy API
+
+The IPFS Proxy now intercepts `/block/put` and `/dag/put` requests. This happens as follows:
+
+* The request is first forwarded "as is" to the underlying IPFS daemon, with
+  the `?pin` query parameter always set to `false`.
+* If `?pin=true` was set, a cluster pin is triggered for every block and dag
+  object uploaded (reminder that these endpoints accept multipart uploads).
+* Regular IPFS response to the uploads is streamed back to the user.
+
+
+##### Go APIs
+
+No relevant changes.
+
+##### Other
+
+Note that more than 10 failed requests to IPFS will now result in a rate-limit
+of 1req/s for any request to IPFS. This may cause things to queue up instead
+hammering the ipfs daemon with requets that fail. The rate limit is removed as
+soon as one request succeeds.
+
+Also note that now Cluster peers that are started will not become fully
+operable until IPFS has been detected to be available: no metrics will be
+sent, no recover operations will be run etc. essentially the Cluster peer will
+wait for IPFS to be available before starting to do things that need IPFS to
+be available, rather than doing them right away and have failures.
