 ## Unreleased
 
-- Fields of type `Bytes` can now use less than and greater than filters [#4285](https://github.com/graphprotocol/graph-node/pull/4285)
+## v0.30.0
+
+### Database locale change
+
+New `graph-node` installations now **mandate** PostgreSQL to use C locale and UTF-8 encoding. The official `docker-compose.yml` template has been updated accordingly. **Pre-existing `graph-node` installations are not concerned with this change**, but local development scripts and CI pipelines may have to adjust database initialization parameters. This can be done with `initdb -E UTF8 --locale=C`. [#4163](https://github.com/graphprotocol/graph-node/pull/4163), [#4151](https://github.com/graphprotocol/graph-node/pull/4151), [#4201](https://github.com/graphprotocol/graph-node/pull/4201), [#4340](https://github.com/graphprotocol/graph-node/pull/4340)
+
+### What's new
+
+- **AND/OR filters.** AND/OR logical operators in `where` filters have been one of `graph-node`'s [most awaited](https://github.com/graphprotocol/graph-node/issues?q=is%3Aissue+sort%3Areactions-%2B1-desc) features. They do exactly what you would expect them to do, and are very powerful. [#579](https://github.com/graphprotocol/graph-node/issues/579), [#4080](https://github.com/graphprotocol/graph-node/pull/4080), [#4171](https://github.com/graphprotocol/graph-node/pull/4171)
+- **IPFS file data sources.** IPFS file data sources allow subgraph developers to query offchain information from IPFS directly in mappings. This feature is the culmination of much community and development efforts (GIP [here](https://forum.thegraph.com/t/gip-file-data-sources/2721)). A future iteration of this feature will also include a so-called "Availability Chain", allowing IPFS file data sources to contribute to Proofs of Indexing. At the moment, entity updates that originate from these data sources' handlers do **not** contribute to PoIs. [#4147](https://github.com/graphprotocol/graph-node/pull/4147), [#4162](https://github.com/graphprotocol/graph-node/pull/4162), and many others!
+- **Sorting by child entities** (a.k.a. nested sorting). You can now `orderBy` properties of child entities. [#4058](https://github.com/graphprotocol/graph-node/pull/4058), [#3737](https://github.com/graphprotocol/graph-node/issues/3737), [#3096](https://github.com/graphprotocol/graph-node/pull/3096)
+- Fields of type `Bytes` can now use less than and greater than filters. [#4285](https://github.com/graphprotocol/graph-node/pull/4285)
+- "userinfo" is now allowed in IPFS URLs (e.g. `https://foo:[email protected]:5001/`). [#4252](https://github.com/graphprotocol/graph-node/pull/4252)
+- The default for `GRAPH_IPFS_TIMEOUT` is now 60 seconds instead of 30. [#4324](https://github.com/graphprotocol/graph-node/pull/4324)
+- Forking options can now be set via env. vars. (`GRAPH_START_BLOCK`, `GRAPH_FORK_BASE`, `GRAPH_DEBUG_FORK`). [#4308](https://github.com/graphprotocol/graph-node/pull/4308)
+- Allow retrieving GraphQL query tracing over HTTP if the env. var. `GRAPH_GRAPHQL_TRACE_TOKEN` is set and the header `X-GraphTraceQuery` is included. The query traces' JSON is the same as returned by `graphman query`. [#4243](https://github.com/graphprotocol/graph-node/pull/4243)
+- Lots of visual and filtering improvements to [#4232](https://github.com/graphprotocol/graph-node/pull/4232)
+- More aggressive in-memory caching of blocks close the chain head, potentially alleviating database load. [#4215](https://github.com/graphprotocol/graph-node/pull/4215)
+- New counter Prometheus metric `query_validation_error_counter`, labelled by deployment ID and error code. [#4230](https://github.com/graphprotocol/graph-node/pull/4230)
+graph_elasticsearch_logs_sent
+- Turned "Flushing logs to Elasticsearch" log into a Prometheus metric (`graph_elasticsearch_logs_sent`) to reduce log noise. [#4333](https://github.com/graphprotocol/graph-node/pull/4333)
+- New materialized view `info.chain_sizes`, which works the same way as the already existing `info.subgraph_sizes` and `info.table_sizes`. [#4318](https://github.com/graphprotocol/graph-node/pull/4318)
+- New `graphman stats` subcommands `set-target` and `target` to manage statics targets for specific deployments (i.e. how much data PostgreSQL samples when analyzing a table). [#4092](https://github.com/graphprotocol/graph-node/pull/4092)
+- Added support for a Firehose-based block ingestor. [#4059](https://github.com/graphprotocol/graph-node/issues/4059), [#4204](https://github.com/graphprotocol/graph-node/pull/4204), [#4216](https://github.com/graphprotocol/graph-node/pull/4216)
+
+### Fixes
+
+- `graph-node` now has PID=1 when running inside the official Docker image. [#4217](https://github.com/graphprotocol/graph-node/pull/4217)
+- More robust `ipfs.cat` logic during grafted subgraphs' manifest lookup. [#4284](https://github.com/graphprotocol/graph-node/pull/4284)
+- Fixed a bug that caused some large multi-entity inserts to fail because of faulty chunk size calculation. [#4250](https://github.com/graphprotocol/graph-node/pull/4250)
+- Subgraph pruning now automatically cancels ongoing autovacuum, to avoid getting stuck. [#4167](https://github.com/graphprotocol/graph-node/pull/4167)
+- `ens.getNameByHash` now fails nondeterministically if [ENS rainbow tables](https://github.com/graphprotocol/ens-rainbow) are not available locally. [#4219](https://github.com/graphprotocol/graph-node/pull/4219)
+- Some kinds of subgraph failures were previously wrongly treated as unattestable (value parsing, `enum` and scalar coercion), i.e. nondeterministic. These subgraph failure modes are now flagged as fully-deterministic. [#4278](https://github.com/graphprotocol/graph-node/pull/4278)
