+## [0.26.0](https://github.com/TimelyDataflow/differential-dataflow/compare/differential-dataflow-v0.25.1...differential-dataflow-v0.26.0) - 2026-11-05
+
+This release targets timely 0.32 and reshapes several public traits.
+The experimental surface from 0.25.0 changes shape again, as expected.
+
+### Changed
+
+- Depends on timely 0.32 from crates.io, replacing the git revision.
+- `Arrange` is removed, and its methods are inherent methods instead. ([#843](https://github.com/TimelyDataflow/differential-dataflow/pull/843))
+- `Batcher<C0>` is now a subtrait of `Extract`, and `Builder` requires `Default` in place of `Sized`. ([#844](https://github.com/TimelyDataflow/differential-dataflow/pull/844), [#846](https://github.com/TimelyDataflow/differential-dataflow/pull/846))
+- `PointStamp` takes its inline capacity as a const parameter `N`, defaulting to 1. ([#1051](https://github.com/TimelyDataflow/differential-dataflow/pull/1051))
+- `JoinTactic` takes the time, both batch types, and the output container as parameters, in the order `<T, B0, B1, C>`.
+- The blanket `Hashable` implementation uses fixed-seed foldhash. Hash-derived values such as `identifiers()` change once. ([#1066](https://github.com/TimelyDataflow/differential-dataflow/pull/1066))
+
+### Other
+

+- Half joins read imported arrangements as of a frontier ([#1025](https://github.com/TimelyDataflow/differential-dataflow/pull/1025))
+- a proxy half-join tactic over a backend, built on int_proxy's public surface ([#1022](https://github.com/TimelyDataflow/differential-dataflow/pull/1022))
+- BackendFrontier reads a proxy backend's inputs as of a frontier ([#1023](https://github.com/TimelyDataflow/differential-dataflow/pull/1023))

+- Chunk pack: combine a carried run once, when emitted ([#902](https://github.com/TimelyDataflow/differential-dataflow/pull/902))
+- Generalize int-proxy keys and values to Copy + Ord ([#891](https://github.com/TimelyDataflow/differential-dataflow/pull/891))
+- Move reduce timestamps and directly evaluate single dominating seeds ([#883](https://github.com/TimelyDataflow/differential-dataflow/pull/883))
+- Group int-proxy reduce pending times into sorted runs ([#881](https://github.com/TimelyDataflow/differential-dataflow/pull/881))
+- Adapt to timely #817, #818, #819 ([#877](https://github.com/TimelyDataflow/differential-dataflow/pull/877))
+- Reuse bounded groups of proxy reduction sweeps ([#871](https://github.com/TimelyDataflow/differential-dataflow/pull/871))
+- Cursor-based clean-up ([#866](https://github.com/TimelyDataflow/differential-dataflow/pull/866))

+- Use `Batcher` to implement all of `Arrange` ([#845](https://github.com/TimelyDataflow/differential-dataflow/pull/845))
+- One `Batcher` trait, shaped like the one half_join had to write ([#844](https://github.com/TimelyDataflow/differential-dataflow/pull/844))
+- Retire the `Arrange` trait in favour of inherent methods ([#843](https://github.com/TimelyDataflow/differential-dataflow/pull/843))
+- Batches as data: spans of history carrying `Option<Batch>` ([#842](https://github.com/TimelyDataflow/differential-dataflow/pull/842))

+- start, emit an empty 'RecordedUpdates' in the columnar 'ValDistributor', when the input consolidates to nothing ([#834](https://github.com/TimelyDataflow/differential-dataflow/pull/834))

+
+This release tracks differential-dataflow 0.26 and removes several helper modules.
+
+### Added
+
+- `HalfJoinTactic` and `half_join_with_tactic`, with proxy and vector backends (`ProxyHalfJoinBackend`, `ProxyHalfJoinTactic`, `VecHalfJoinBackend`).
+
+### Changed
+
+- `half_join` is re-exported from `operators::half_join::cursors`, and its signature drops the `CF` parameter.
+- `PrefixExtender`, `ProposeExtensionMethod`, and `ValidateExtensionMethod` drop the `R` parameter.
+- `CollectionIndex` and `CollectionExtender` drop the `R` parameter and gain a `'scope` lifetime.
+- `count`, `propose`, and `validate` take the `R` and `FF` type parameters.
+
+### Removed
+
+- `AltNeu`, and the `calculus` module with `Differentiate` and `Integrate`.
+- `lookup_map`, `propose_distinct`, and the `half_join2` module.
+- The old `half_join_internal_unsafe`. The `half_join::cursors` module has its own version.
+
+### Other
+
+- `Batcher` as subtrait ([#1074](https://github.com/TimelyDataflow/differential-dataflow/pull/1074))
