+## [v7.1.0](https://github.com/prysmaticlabs/prysm/compare/v7.0.0...v7.1.0) - 2025-12-10
+
+This release includes several key features/fixes. If you are running v7.0.0 then you should update to v7.0.1 or later and remove the flag `--disable-last-epoch-targets`. 
+
+Release highlights:
+
+- Backfill is now supported in Fulu. Backfill from checkpoint sync now supports data columns. Run with `--enable-backfill` when using checkpoint sync.
+- A new node configuration to custody enough data columns to reconstruct blobs. Use flag `--semi-supernode` to custody at least 50% of the data columns.
+- Critical fixes in attestation processing.
+
+A post mortem doc with full details on the mainnet attestation processing issue from December 4th is expected in the coming days. 
+
+### Added
+
+- add fulu support to light client processing. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15995)
+- Record data column gossip KZG batch verification latency in both the pooled worker and fallback paths so the `beacon_kzg_verification_data_column_batch_milliseconds` histogram reflects gossip traffic, annotated with `path` labels to distinguish the sources. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16018)
+- Implement Gloas state. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15611)
+- Add initial configs for the state-diff feature. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15903)
+- Add kv functions for the state-diff feature. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15903)
+- Add supported version for fork versions. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16030)

+- Integrate state-diff into `State()`. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16033)
+- Implement Gloas fork support in consensus-types/blocks with factory methods, getters, setters, and proto handling. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15618)
+- Integrate state-diff into `HasState()`. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16045)
+- Added `--semi-supernode` flag to custody half of a super node's datacolumn requirements but allowing for reconstruction for blob retrieval. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16029)
+- Data column backfill. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15580)
+- Backfill metrics for columns: backfill_data_column_sidecar_downloaded, backfill_data_column_sidecar_downloaded_bytes, backfill_batch_columns_download_ms, backfill_batch_columns_verify_ms. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15580)
+- prometheus summary `gossip_data_column_sidecar_arrival_milliseconds` to track data column sidecar arrival latency since slot start. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16099)
+
+### Changed
+
+- Improve readability in slashing import and remove duplicated code. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15957)
+- Use dependent root instead of target when possible. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15996)
+- Changed `--subscribe-all-data-subnets` flag to `--supernode` and aliased `--subscribe-all-data-subnets` for existing users. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16012)
+- Use explicit slot component timing configs. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15999)
+- Downgraded log level from INFO to DEBUG on PrepareBeaconProposer updated fee recipients. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15998)
+- Change the logging behaviour of Updated fee recipients to only log count of validators at Debug level and all validator indices at Trace level. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15998)
+- Stop emitting payload attribute events during late block handling when we are not proposing the next slot. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16026)
+- Initialize the `ExecutionRequests` field in gossip block map. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16047)

+- `WithGenesisValidatorsRoot`: Use camelCase for log field param. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16075)
+- Move `Origin checkpoint found in db` from WARN to INFO, since it is the expected behaviour. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16075)
+- backfill metrics that changed name and/or histogram buckets: backfill_batch_time_verify -> backfill_batch_verify_ms, backfill_batch_time_waiting -> backfill_batch_waiting_ms, backfill_batch_time_roundtrip -> backfill_batch_roundtrip_ms, backfill_blocks_bytes_downloaded -> backfill_blocks_downloaded_bytes, backfill_batch_time_verify -> backfill_batch_verify_ms, backfill_batch_blocks_time_download -> backfill_batch_blocks_download_ms, backfill_batch_blobs_time_download -> backfill_batch_blobs_download_ms, backfill_blobs_bytes_downloaded -> backfill_blocks_downloaded_bytes.

As of this release, the feature flag `--disable-last-epoch-targets` has been deprecated and can be safely removed from your node configuration. 
+
+A post mortem doc with full details is expected to be published later this week.
+
+### Changed
+
+- Move the "Not enough connected peers" (for a given subnet) from WARN to DEBUG. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16087)
+- Use dependent root instead of target when possible. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15996)
+- Introduced flag `--ignore-unviable-attestations` (replaces and deprecates `--disable-last-epoch-targets`) to drop attestations whose target state is not viable; default remains to process them unless explicitly enabled. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16094)
+
+### Fixed
+
+- Use head state to validate attestations for old blocks if they are compatible. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16095)
+
+
+## [v7.0.0](https://github.com/prysmaticlabs/prysm/compare/v6.1.4...v7.0.0) - 2025-11-10
+
+This is our initial mainnet release for the Ethereum mainnet Fulu fork on December 3rd, 2025. All operators MUST update to v7.0.0 or later release prior to the fulu fork epoch `411392`. See the [Ethereum Foundation blog post](https://blog.ethereum.org/2025/11/06/fusaka-mainnet-announcement) for more information on Fulu.
+
+Other than the mainnet fulu fork schedule, there are a few callouts in this release:
+- `by-epoch` blob storage format is the default for new installations. Users that haven't migrated will see a warning to migrate to the new format. Existing deployments may set `--blob-storage-layout=by-epoch` to perform the migration.
+- Several deprecated flags have been deleted! Please review the "removed" section of this changelog carefully. If you are referencing a removed flag, Prysm will not start! All of these flags had no effect for at least one release.
+- Several deprecated API endpoints have been deleted. Please review the "removed" section of this changelog carefully. 
+- Backfill is not supported in Fulu. This is expected to be fixed in the next release and should be delivered prior to the mainnet activation fork.
+- The builder default gas limit is raised from `45000000` (45 MGas) to `60000000` (60 MGas).
+- Several bug fixes and improvements.

+- Fixed [#15812](https://github.com/OffchainLabs/prysm/issues/15812): Gossip attestation validation incorrectly rejecting attestations that arrive before their referenced blocks. Previously, attestations were saved to the pending queue but immediately rejected by forkchoice validation, causing "not descendant of finalized checkpoint" errors. Now attestations for missing blocks return `ValidationIgnore` without error, allowing them to be properly processed when their blocks arrive. This eliminates false positive rejections and prevents potential incorrect peer downscoring during network congestion. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15840)
+- Mark the block as invalid if it has an invalid signature. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15847)

+- `dataColumnSidecarsByRangeRPCHandler`: Gracefully close the stream if no data to return. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15866)
+- `VerifyDataColumnSidecar`: Check if there is no too many commitments. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15859)
+- `WithDataColumnRetentionEpochs`: Use `dataColumnRetentionEpoch` instead of `blobColumnRetentionEpoch`. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15872)
+- Mark epoch transition correctly on new head events. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15871)
+- reject committee index >= committees_per_slot in unaggregated attestation validation. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15855)
+- Decreased attestation gossip validation batch deadline to 5ms. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15882)
+
+## [v6.1.2](https://github.com/prysmaticlabs/prysm/compare/v6.1.1...v6.1.2) - 2025-10-10
+
+This release has several important fixes to improve Prysm's peering, stability, and attestation inclusion on mainnet and all testnets. All node operators are encouraged to update to this release as soon as practical for the best mainnet performance.

+## [v6.1.0](https://github.com/prysmaticlabs/prysm/compare/v6.0.5...v6.1.0) and [v6.1.1](https://github.com/prysmaticlabs/prysm/compare/v6.1.0...v6.1.1) - 2025-09-26
+
+This release has support for Fusaka testnets as well as many mainnet improvements. Testnet operators are required to updated prior to the testnet fork date. See [PR #15721](https://github.com/OffchainLabs/prysm/pull/15721).
+
+Mainnet operators are encouraged to update per their regular update cadence. 
+
+Note: This release was re-issued as v6.1.1 to distribute release assets without debug symbols. See issue [#15760](https://github.com/OffchainLabs/prysm/issues/15760).
+
+#### Noteworthy improvements, changes and bugfixes:
+- The `--disable-experimental-state` beacon-node flag has been removed, marking the full graduation of the [Copy-on-write design](https://hackmd.io/zlTJ6Qe_RiueT3y2R77BvA) for BeaconState fields, which reduces the memory overhead of keeping multiple BeaconStates in RAM for block processing. Congrats @rkapka!
+- The behavior set by the `--attest_timely` flag is now on by default, with the flag itself deprecated.
+- GetDutiesV2 introduced, lowering duty request latency and beacon-node load. Multiple other improvements and bugfixes have been made to harden the validator run loop.
+- New validator flag `--max-health-checks` configures a validator to switch to a fallback beacon node after the given number of health check failures.
+- Improvements to rest-mode validator, defaulting to SSZ where available and adding SSZ support to more Beacon API endpoints.
+- Beacon API now honors the gzip content-encoding header.
+- Log timestamps now include milliseconds.
+- Full fusaka support for testnets! 
+
+**Special thanks to external contributors!**: @Alleysira, @KaloyanTanev, @rose2221
