+### Upgrade Notes
+
+When upgrading to this version, we recommend taking a brief look into these changes:
+
+- Gas metering #2414
+  - Now there's a gas limit for subgraph mappings, if the limit is reached the subgraph will fail with a non-deterministic error, you can make them recover via the environment variable `GRAPH_MAX_GAS_PER_HANDLER`
+- Improve our `CacheWeight` estimates #2935
+  - This is relevant because a couple of releases back we've added a limit for the memory size of a query result. That limit is based of the `CacheWeight`.
+
+These are some of the features that will probably be helpful for indexers 😊
+
+- Allow placing new deployments onto one of several shards #3049
+- GraphQL route for dumping entity changes in subgraph and block #3275
+- Unused deployments are automatically removed now #3023
+  - The interval can be set via `GRAPH_REMOVE_UNUSED_INTERVAL`
+- Setup databases in parallel #3019
+- Block ingestor now fetches receipts in parallel #3030
+  - `GRAPH_ETHEREUM_FETCH_TXN_RECEIPTS_IN_BATCHES` can be set to `true` for the old fetching behavior
+- More robust `proofOfIndexing` GraphQL route #3348
+  - A token can be set via `GRAPH_POI_ACCESS_TOKEN` to limit access to the POI route
+- The new `graphman` commands 🙂
