+# [2.76.0] - Unreleased
+
+## Highlights
+
+* New highly anticipated feature X added to Python SDK ([#X](https://github.com/apache/beam/issues/X)).
+* New highly anticipated feature Y added to Java SDK ([#Y](https://github.com/apache/beam/issues/Y)).
+
+## I/Os
+
+* Support for X source added (Java/Python) ([#X](https://github.com/apache/beam/issues/X)).
+
+## New Features / Improvements
+
+* (Python) Removed the `envoy-data-plane` (and transitive `betterproto`) dependency; `EnvoyRateLimiter` now uses a small vendored protobuf definition instead, resolving dependency conflicts for downstream projects ([#37854](https://github.com/apache/beam/issues/37854)).
+* X feature added (Java/Python) ([#X](https://github.com/apache/beam/issues/X)).
+
+## Breaking Changes
+
+* X behavior was changed ([#X](https://github.com/apache/beam/issues/X)).
+
+## Deprecations
+
+* X behavior is deprecated and will be removed in X versions ([#X](https://github.com/apache/beam/issues/X)).
+
+## Bugfixes
+
+* Fixed unbounded checkpoint state growth for splittable DoFns that self-checkpoint on the portable Flink runner (Java) ([#27648](https://github.com/apache/beam/issues/27648)).
+* Fixed X (Java/Python) ([#X](https://github.com/apache/beam/issues/X)).
+
+## Security Fixes
+
+* Fixed [CVE-YYYY-NNNN](https://www.cve.org/CVERecord?id=CVE-YYYY-NNNN) (Java/Python/Go) ([#X](https://github.com/apache/beam/issues/X)).

-* (Python) Removed the `envoy-data-plane` (and transitive `betterproto`) dependency; `EnvoyRateLimiter` now uses a small vendored protobuf definition instead, resolving dependency conflicts for downstream projects ([#37854](https://github.com/apache/beam/issues/37854)).
 * 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)).
 * (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)).
 * (Python) Added instrumentation to support off-the-shelf profiling agents when launching Python SDK Harness ([#38853](https://github.com/apache/beam/issues/38853)).

 * 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)).
 * Fixed BigQueryEnrichmentHandler batch mode dropping earlier requests when multiple requests share the same enrichment key (Python) ([#38035](https://github.com/apache/beam/issues/38035)).
 * 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)).
