-## [v7.1.2](https://github.com/prysmaticlabs/prysm/compare/v7.1.1...v7.1.2) - 2026-01-07
-
-Happy new year! This patch release is very small. The main improvement is better management of pending attestation aggregation via [PR 16153](https://github.com/OffchainLabs/prysm/pull/16153).
-
-### Added
-
-- `primitives.BuilderIndex`: SSZ `uint64` wrapper for builder registry indices. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16169)
-
-### Changed
-
-- the /eth/v2/beacon/pool/attestations and /eth/v1/beacon/pool/sync_committees now returns a 503 error if the node is still syncing, the rest api is also working in a similar process to gRPC broadcasting immediately now. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16152)
-- `validateDataColumn`: Remove error logs. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16157)
-- Pending aggregates: When multiple aggregated attestations only differing by the aggregator index are in the pending queue, only process one of them. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16153)
-
-### Fixed
-
-- Fix the missing fork version object mapping for Fulu in light client p2p. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16151)
-- Do not process slots and copy states for next epoch proposers after Fulu. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16168)
