 ## [Unreleased]
 
+## [2.1.0-rc.0] - 2026-09-27
+
+### Added
+
+- Added a prepared Groth16 batch verifying key that reuses fixed pairing
+  terms across repeated batches
+  ([#487](https://github.com/zakura-core/common/pull/487)).
+- Added joint verification of two Groth16 batches with prepared keys,
+  sharing one Miller loop and final exponentiation
+  ([#496](https://github.com/zakura-core/common/pull/496)).
+- Added reusable fixed G2 terms that a Groth16 batch verifying key can borrow
+  ([#499](https://github.com/zakura-core/common/pull/499)).
+
+### Changed
+
+- Sped up single Groth16 proof verification when a prepared verifying key is
+  reused, especially for proofs with several public inputs
+  ([#482](https://github.com/zakura-core/common/pull/482)).
+- Sped up multicore Groth16 batch verification, especially for batches
+  smaller than the Rayon thread count
+  ([#483](https://github.com/zakura-core/common/pull/483)).
+- Switched Groth16 proof finalization and ordinary verification to the
+  explicit variable-time affine conversion hooks. Prover timing can now
+  depend on witness-derived projective coordinates; batch verification
+  continues to use its existing conversion for points involving private batch
+  randomizers
+  ([#494](https://github.com/zakura-core/common/pull/494)).
+- Sped up repeated Groth16 verification with a prepared verifying key,
+  including prepared batch verifying keys
+  ([#495](https://github.com/zakura-core/common/pull/495)).

 ## [Unreleased]
 
+## [2.1.0-rc.0] - 2026-09-27
+
+### Changed
+
+- Sped up final exponentiation, and therefore pairings, using variable-time
+  field inversion. Pairing, final exponentiation, and random target-group
+  generation now have documented input-dependent timing and are intended for
+  public inputs such as Groth16 proofs
+  ([#485](https://github.com/zakura-core/common/pull/485),
+  [#494](https://github.com/zakura-core/common/pull/494),
+  [#501](https://github.com/zakura-core/common/pull/501)).
+- Sped up prepared multi-pairing Miller loops
+  ([#489](https://github.com/zakura-core/common/pull/489)).
+- Implemented the new affine-conversion hooks with variable-time inversion for
+  G1 and G2 projective points. Timing can depend on projective coordinates
+  ([#494](https://github.com/zakura-core/common/pull/494)).
+- Sped up Miller loops with reusable prepared G2 points
+  ([#495](https://github.com/zakura-core/common/pull/495)).

 ## [Unreleased]
 
+## [2.1.0-rc.0] - 2026-09-27
+
+### Added
+
+- Added Equihash verification and the optional Tromp CPU solver as the
+  `zakura-equihash` package, preserving the `equihash` library target and
+  upstream `0.3.0` public API
+  ([#44](https://github.com/zakura-core/common/pull/44)).
+
+### Changed
+
+- Raised the minimum supported Rust version from 1.85.1 to 1.91 and adopted
+  the Zakura Common workspace version and package metadata
+  ([#44](https://github.com/zakura-core/common/pull/44)).
+- Removed the C compiler requirement for the optional `solver` feature by
+  implementing solution generation in Rust
+  ([#509](https://github.com/zakura-core/common/pull/509)).
+- Reduced CPU time for Equihash `(200, 9)` solution generation through the
+  optional `solver` feature, with additional fast paths on supported x86-64
+  CPUs
+  ([#502](https://github.com/zakura-core/common/pull/502),
+  [#504](https://github.com/zakura-core/common/pull/504),
+  [#506](https://github.com/zakura-core/common/pull/506),

+  [#515](https://github.com/zakura-core/common/pull/515),
+  [#516](https://github.com/zakura-core/common/pull/516)).
+- `is_valid_solution` now rejects inputs unless `input` and `nonce` together
+  are a 140-byte Zcash block header and nonce
+  ([#514](https://github.com/zakura-core/common/pull/514)).
+- Sped up `is_valid_solution` by about 1.7–2.9×, using AVX2 or NEON where
+  available
+  ([#514](https://github.com/zakura-core/common/pull/514)).
+
+### Fixed
+
+- `is_valid_solution` now returns an invalid-parameters error, instead of
+  panicking, for `(n, k)` with `n > 512` or a collision length outside 8 to
+  24 bits
+  ([#514](https://github.com/zakura-core/common/pull/514)).
