+## v1.4.2
+
+### Highlights
+
+* This release brings an update to `substreams` to `v1.1.3` which includes the following:
+  - Fixes an important bug that could have generated corrupted store state files. This is important for developers and operators.
+  - Fixes for race conditions that would return a failure when multiple identical requests are backprocessing.
+  - Fixes and speed/scaling improvements around the engine.
+
+### Note for Operators
+
+> **Note** This upgrade procedure is applies if your Substreams deployment topology includes both `tier1` and `tier2` processes. If you have defined somewhere the config value `substreams-tier2: true`, then this applies to you, otherwise, if you can ignore the upgrade procedure.
+
+This release includes a small change in the internal RPC layer between `tier1` processes and `tier2` processes. This change requires an ordered upgrade of the processes to avoid errors.
+
+The components should be deployed in this order:
+1. Deploy and roll out `tier1` processes first
+2. Deploy and roll out `tier2` processes in second
+
+If you upgrade in the wrong order or if somehow `tier2` processes start using the new protocol without `tier1` being aware, user will end up with backend error(s) saying that some partial file are not found. Those will be resolved only when `tier1` processes have been upgraded successfully.
