-## [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.

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.

-## [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!

-- Fixed gocognit on propose block rest path. [[PR]](https://github.com/prysmaticlabs/prysm/pull/15147)
-
-## [v6.0.1](https://github.com/prysmaticlabs/prysm/compare/v6.0.0...v6.0.1) - 2025-05-02
-
-This release fixes two bugs related to the `payload_attributes` [event stream](https://ethereum.github.io/beacon-APIs/#/Events/eventstream). If you are using or planning to use this endpoint, upgrading to version 6.0.1 is mandatory.  
-Also, a reminder: like other Beacon API endpoints, when a node is syncing, it may return historical data as `finalized` or `head`. Until the node is fully synced to the head of the chain, you should avoid using this data, depending on your application's needs.
-
-We currently recommend against using the `--enable-beacon-rest-api` flag on Mainnet. As you may have noticed, we put a deprecation notice on our gRPC code, in particular on gRPC-related flags. The reason for this is that we want to eventually remove gRPC and have REST HTTP as the standard way of communication between the validator client and the beacon node. That being said, the REST option is still unstable and thus marked as experimental in the flag's description (the flag is `--enable-beacon-rest-api`). Therefore we encourage everyone to keep using gRPC, which is currently the default. It is fine to test the REST option on testnets, but doing it on Mainnet can lead to missing attestations and even missing blocks.
-
-**Updating to v6.0.0 or later is required for Pectra Mainnet!**
-
-This patch release has a few important fixes from v6.0.0. Updating to this release is encouraged.

-## [v6.0.0](https://github.com/prysmaticlabs/prysm/compare/v5.3.2...v6.0.0) - 2025-04-21
-
-This release introduces Mainnet support for the upcoming Electra + Prague (Pectra) fork. The fork is scheduled for mainnet epoch 364032 (May 7, 2025, 10:05:11 UTC). You MUST update Prysm Beacon Node, Prysm Validator Client, and your execution layer client to the Pectra ready release prior to the fork to stay on the correct chain.
-
-Besides Pectra, we have more light client API support, cleanups, and a few bugfixes. Please review the changelog below and update your client as soon as practical before May 7.
-
-This release is **mandatory** for all operators before May 7.
