+## 9.1.0
+
+#### Project
+
+* [**IMPORTANT**] Remove InfluxDB 1.x and Apache IoTDB 0.X as storage options, check details
+  at [here](https://github.com/apache/skywalking/discussions/9059). Remove converter-moshi 2.5.0, influx-java 2.15,
+  iotdb java 0.12.5, thrift 0.14.1, moshi 1.5.0, msgpack 0.8.16 dependencies. Remove InfluxDB and IoTDB relative codes
+  and E2E tests.
+* Upgrade OAP dependencies zipkin to 2.23.16, H2 to 2.1.212, Apache Freemarker to 2.3.31, gRPC-java 1.46.0, netty to
+  4.1.76.
+* Upgrade Webapp dependencies, spring-cloud-dependencies to 2021.0.2, logback-classic to 1.2.11
+* [**IMPORTANT**] Add BanyanDB storage implementation. Notice BanyanDB is currently under active development
+  and **SHOULD NOT** be used in production cluster.
+
+#### OAP Server
+
+* Add component definition(ID=127) for `Apache ShenYu (incubating)`.
+* Fix Zipkin receiver: Decode spans error, missing `Layer` for V9 and wrong time bucket for generate Service and
+  Endpoint.
+* [Refactor] Move SQLDatabase(H2/MySQL/PostgreSQL), ElasticSearch and BanyanDB specific configurations out of column.
+* Support BanyanDB global index for entities. Log and Segment record entities declare this new feature.
+* Remove unnecessary analyzer settings in columns of templates. Many were added due to analyzer's default value.
+* Simplify the Kafka Fetch configuration in cluster mode.
+* [Breaking Change] Update the eBPF Profiling task to the service level, please delete
+  index/table: `ebpf_profiling_task`, `process_traffic`.
+* Fix event can't split service ID into 2 parts.
+* Fix OAP Self-Observability metric `GC Time` calculation.
+* Set `SW_QUERY_MAX_QUERY_COMPLEXITY` default value to `1000`
+* Webapp module (for UI) enabled compression.
+* [Breaking Change] Add layer field to event, report an event without layer is not allowed.
+* Fix ES flush thread stops when flush schedule task throws exception, such as ElasticSearch flush failed.
+* Fix ES BulkProcessor in BatchProcessEsDAO was initialized multiple times and created multiple ES flush schedule tasks.
+* HTTPServer support the handler register with allowed HTTP methods.
+* [Critical] Revert [**Enhance DataCarrier#MultipleChannelsConsumer to add
+  priority**](https://github.com/apache/skywalking/pull/8664) to avoid consuming issues.
+* Fix the problem that some configurations (such as group.id) did not take effect due to the override order when using
+  the kafkaConsumerConfig property to extend the configuration in Kafka Fetcher.
+* Remove build time from the OAP version.
+* Add data-generator module to run OAP in testing mode, generating mock data for testing.
+* Support receive Kubernetes processes from gRPC protocol.
+* Fix the problem that es index(TimeSeriesTable, eg. endpoint_traffic, alarm_record) didn't create even after rerun with
+  init-mode. This problem caused the OAP server to fail to start when the OAP server was down for more than a day.
+* Support autocomplete tags in traces query.
+* [Breaking Change] Replace all configurations `**_JETTY_**` to `**_REST_**`.
+* Add the support eBPF profiling field into the process entity.
+* E2E: fix log test miss verify LAL and metrics.
+* Enhance Converter mechanism in kernel level to make BanyanDB native feature more effective.
+* Add TermsAggregation properties collect_mode and execution_hint.
+* Add "execution_hint": "map", "collect_mode": "breadth_first" for aggregation and topology query to improve 5-10x
+  performance.
+* Clean up scroll contexts after used.
+* Support autocomplete tags in logs query.
+* Enhance Deprecated MetricQuery(v1) getValues querying to asynchronous concurrency query
+* Fix the pod match error when the service has multiple selector in kubernetes environment.
+* VM monitoring adapts the 0.50.0 of the `opentelemetry-collector`.
+* Add Envoy internal cost metrics.
+* Remove `Layer` concept from `ServiceInstance`.
+* Remove unnecessary `onCompleted` on gRPC `onError` callback.
+* Remove `Layer` concept form `Process`.
+* Update to list all eBPF profiling schedulers without duration.
+* Storage(ElasticSearch): add search options to tolerate inexisting indices.
+* Fix the problem that `MQ` has the wrong `Layer` type.
+* Fix NoneStream model has wrong downsampling(was Second, should be Minute).
+* SQL Database: provide `@SQLDatabase.AdditionalEntity` to support create additional tables from a model.
+* [Breaking Change] SQL Database: remove SQL Database config `maxSizeOfArrayColumn` and `numOfSearchableValuesPerTag`.
+* [Breaking Change] SQL Database: move `Tags list` from `Segment`,`Logs`,`Alarms` to their additional table.
+* [Breaking Change] Remove `total` field in Trace, Log, Event, Browser log, and alarm list query.
+* Support `OFF_CPU` eBPF Profiling.
+* Fix SumAggregationBuilder#build should use the SumAggregation rather than MaxAggregation.
+* Add TiDB, OpenSearch, Postgres storage optional to Trace and eBPF Profiling E2E testing.
+* Add OFF CPU eBPF Profiling E2E Testing.
+* Fix searchableTag as `rpc.status_code` and `http.status_code`. `status_code` had been removed.
+* Fix scroll query failure exception.
+* Add `profileDataQueryBatchSize` config in Elasticsearch Storage.
+* Add APIs to query Pod log on demand.
+* Remove OAL for events.
+* Simplify the format index name logical in ES storage.
+* Add instance properties extractor in MAL.
+* Support Zipkin traces collect and zipkin traces query API.
+* [Breaking Change] Zipkin receiver mechanism changes and traces do not stream into OAP Segment anymore.
+
+#### UI
+
+* General service instance: move `Thread Pool` from JVM to Overview, fix `JVM GC Count` calculation.
+* Add Apache ShenYu (incubating) component LOGO.
+* Show more metrics on service/instance/endpoint list on the dashboards.
+* Support average values of metrics on the service/list/endpoint table widgets, with pop-up linear graph.
+* Fix viewLogs button query no data.
+* Fix UTC when page loads.
+* Implement the eBPF profile widget on dashboard.
+* Optimize the trace widget.
+* Avoid invalid query for topology metrics.
+* Add the alarm and log tag tips.
+* Fix spans details and task logs.
+* Verify query params to avoid invalid queries.
+* Mobile terminal adaptation.
+* Fix: set dropdown for the Tab widget, init instance/endpoint relation selectors, update sankey graph.
+* Add eBPF Profiling widget into General service, Service Mesh and Kubernetes tabs.
+* Fix jump to endpoint-relation dashboard template.
+* Fix set graph options.
+* Remove the `Layer` filed from the Instance and Process.
+* Fix date time picker display when set hour to `0`.
+* Implement tags auto-complete for Trace and Log.
+* Support multiple trees for the flame graph.
+* Fix the page doesn't need to be re-rendered when the url changes.
