This PR introduces 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.

+## [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.

+- `dataColumnSidecarByRootRPCHandler`: Do not serve a sidecar if the corresponding block is not available. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15933)
+- Fix incorrect version used when sending attestation version in Fulu. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15950)
+- Changed the behavior of topic subscriptions such that only topics that require the active validator count will compute that value. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15955)
+- Added a Mutex to the computation of active validator count during topic subscription to avoid a race condition where multiple goroutines are computing the same work. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15955)
+- `RODataColumnsVerifier.ValidProposerSignature`: Ensure the expensive signature verification is only performed once for concurrent requests for the same signature data. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15954)

+- Improve error message when the byte count read from disk when reading a data column sidecars is lower than expected. (Mostly, because the file is truncated.). [[PR]](https://github.com/prysmaticlabs/prysm/pull/15881)
+- Delete the genesis state file when --clear-db / --force-clear-db is specified. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15883)
+- Fix sync committee subscription to use subnet indices instead of committee indices. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15885)
+- Fixed metadata extraction on Windows by correctly splitting file paths. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15899)
+- `VerifyDataColumnsSidecarKZGProofs`: Check if sizes match. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15892)
+- Fix recoverStateSummary to persist state summaries in stateSummaryBucket instead of stateBucket (#15896). [[PR]](https://github.com/prysmaticlabs/prysm/pull/15896)
+- `updateCustodyInfoInDB`: Use `NumberOfCustodyGroups` instead of `NumberOfColumns`. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15908)
+- Sync committee uses correct state to calculate position. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15905)
+
+## [v6.1.3](https://github.com/prysmaticlabs/prysm/compare/v6.1.2...v6.1.3) - 2025-10-20
+
+This release has several important beacon API and p2p fixes.
+
+### Added
+
+- Add Grandine to P2P known agents. (Useful for metrics). [[PR]](https://github.com/prysmaticlabs/prysm/pull/15829)
+- Delegate sszInfo HashTreeRoot to FastSSZ-generated implementations via SSZObject, enabling roots calculation for generated types while avoiding duplicate logic. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15805)
+- SSZ-QL: Use `fastssz`'s `SizeSSZ` method for calculating the size of `Container` type. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15864)
+- SSZ-QL: Access n-th element in `List`/`Vector`. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15767)
+
+### Changed
+
+- Do not verify block data when calculating rewards. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15819)
+- Process pending attestations after pending blocks are cleared. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15824)
+- updated web3signer to 25.9.1. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15832)
+- Gracefully handle submit blind block returning 502 errors. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15848)
+- Improve returning individual message errors from Beacon API. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15835)
+- SSZ-QL: Clarify `Size` method with more sophisticated `SSZType`s. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15864)
+
+### Fixed
+
+- Use service context and continue on slasher attestation errors (#15803). [[PR]](https://github.com/prysmaticlabs/prysm/pull/15803)
+- block event probably shouldn't be sent on certain block processing failures, now sends only on successing processing Block is NON-CANONICAL, Block IS CANONICAL but getFCUArgs FAILS, and Full success. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15814)
+- Fixed web3signer e2e, issues caused due to a regression on old fork support. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15832)
+- Do not mark blocks as invalid from ErrNotDescendantOfFinalized. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15846)
+- 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)
+- Display error messages from the server verbatim when they are not encoded as `application/json`. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15860)
+- `HasAtLeastOneIndex`: Check the index is not too high. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15865)
+- Fix `/eth/v1/beacon/blob_sidecars/` beacon API is the fulu fork epoch is set to the far future epoch. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15867)
+- `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.
