| 29 | + |
| 30 | +## Highlights |
| 31 | + |
| 32 | +* Python SDK now supports memory profiling with Memray ([#38853](https://github.com/apache/beam/issues/38853)). |
| 33 | +* (Python) Added [Qdrant](https://qdrant.tech/) VectorDatabaseWriteConfig implementation ([#38141](https://github.com/apache/beam/issues/38141)). |
| 34 | + |
| 35 | +### I/Os |
| 36 | + |
| 37 | +* Support for reading from Delta Lake added (Java) ([#38551](https://github.com/apache/beam/issues/38551)). |
| 38 | +* ClickHouseIO: support writing `DateTime64(precision[, 'timezone'])` columns with sub-second precision (Java) ([#38466](https://github.com/apache/beam/issues/38466)). |
| 39 | +* Upgraded IO Expansion Service to Java 17 ([#38974](https://github.com/apache/beam/issues/38974)). |
| 40 | + |
| 41 | +### New Features / Improvements |
| 42 | + |
| 43 | +* Dataflow Runner v2 has been renamed to Dataflow Portable Runner. Please refer to Dataflow [public documentation](https://docs.cloud.google.com/dataflow/docs/runner-v2) on when to enable Portable Runner.([#39000](https://github.com/apache/beam/issues/39000)). |
| 44 | +* (Java) Enabled state tag encoding v2 by default for new Dataflow Streaming Engine jobs. It can be disabled by passing `--experiments=disable_streaming_engine_state_tag_encoding_v2` or `--updateCompatibilityVersion=2.74.0` pipeline option. Note that the tag encoding version cannot change during a job update. Jobs using tag encoding v2 (enabled by default for new jobs on 2.75.0+) cannot be downgraded to Beam versions prior to 2.73.0, as only versions 2.73.0 and later support tag encoding v2. ([#38705](https://github.com/apache/beam/issues/38705)). |
| 45 | +* (Python) Added instrumentation to support off-the-shelf profiling agents when launching Python SDK Harness ([#38853](https://github.com/apache/beam/issues/38853)). |
| 46 | +* (Java) Added support to the FnApi Data stream protocol allowing runners to isolate bundles slowly processing input from other bundles. ([#39001](https://github.com/apache/beam/issues/39001)). |
| 47 | +* (YAML) Switched js2py library to Quickjs ([#38473](https://github.com/apache/beam/issues/38473)). |
| 48 | +* (YAML) Added HuggingFaceModelHandler for YAML usage ([#38696](https://github.com/apache/beam/issues/38696)). |
| 49 | +* (YAML) Added WriteToMongoDB transform ([#38376](https://github.com/apache/beam/issues/38376)). |
| 50 | +* (YAML) Added WriteToDatadog transform ([#38362](https://github.com/apache/beam/issues/38362)). |
| 51 | +* (Java) Flink 2.1 and 2.2 support is added ([#38947](https://github.com/apache/beam/issues/38947)) ([#38978](https://github.com/apache/beam/issues/38978)); Flink 1.17 and 1.18 support is dropped. |
| 52 | +* (Python) MqttIO is now supported in Python via cross-language ([#21060](https://github.com/apache/beam/issues/21060)). |
| 53 | + |
| 54 | +### Breaking Changes |
| 55 | + |
| 56 | +* (Python) Typehints of dataclass fields are honored during type inferences. To restore the behavior of fallback-to-any, |
| 57 | + use pipeline option `--exclude_infer_dataclass_field_type` ([#38797](https://github.com/apache/beam/issues/38797)). |
| 58 | + However fixing forward is recommended. |
| 59 | + |
| 60 | +### Bugfixes |
| 61 | + |
| 62 | +* Fixed GCS filesystem glob matching to correctly handle `/` in object names and support `**` for recursive matching (Go) ([#38059](https://github.com/apache/beam/issues/38059)). |
| 63 | +* Fixed BigQueryEnrichmentHandler batch mode dropping earlier requests when multiple requests share the same enrichment key (Python) ([#38035](https://github.com/apache/beam/issues/38035)). |
| 64 | +* Fixed IcebergIO writing manifest column bounds padded with trailing `0x00` bytes, which broke equality predicate pushdown in some query engines (Java) ([#38580](https://github.com/apache/beam/issues/38580)). |
| 65 | + |
| 66 | +### Known Issues |
| 67 | + |
| 68 | +* (Java) Projects using the Flink runner with Flink 2.1 or later alongside libraries requiring `org.lz4:lz4-java` (e.g., Kafka clients) may encounter a Gradle capability conflict, because Flink 2.1+ ships `at.yawk.lz4:lz4-java` which declares the same capability. To resolve, add a `capabilitiesResolution` rule to your `build.gradle` that selects `at.yawk.lz4:lz4-java` ([#38947](https://github.com/apache/beam/issues/38947)). |
