It continues the implementation work for the upcoming Amsterdam hardfork.\nA few things worth highlighting:\nThe default GOGC has changed from 20 to 50, trading a higher memory peak for less GC overhead. Set --gogc=20 to keep the old behavior.\nPebble v2 is now supported as a key-value store backend. Pebble v2 is used when Geth is bootstrapped from scratch, and falls back to Pebble v1 for a pre-existing database. Run geth db pebble-upgrade to explicitly upgrade a legacy Pebble v1 database to v2.\nFork Implementation\nSeveral Amsterdam EIPs have been implemented or updated:\nEIP-2780: Resource-based intrinsic transaction gas (#35212, #35318)\nEIP-8037: State creation gas cost increase (#35173, #35318, #35301, #35342, #35279)\nEIP-8038: State-access gas cost update (#35216)\nEIP-8246: Remove SELFDESTRUCT burn (#35219)\nEIP-8282: Builder execution requests (#35175, #35341)\nEIP-7997: Deterministic factory contract (#35223, #35285)\nEIP-7954: Increase maximum contract size (#35217)\nEIP-7928: Block-level access lists (#35260, #35281, #35261, #35348, #35279)\nImprove Amsterdam fork test coverage (#35364)\nIntroduce the --override.amsterdam flag (#35213)\nRemove named hardforks from the BPO schedule (#35029)\nIntroduce the Bogota fork in the chain configuration (#34057)\nCore\nIntroduce a sparse blobpool to reduce blob transaction pool memory usage (#34047)\nMigrate legacy blobpool limbo entries to the new cell-based sidecar format on startup (#35209)\nDrop support for v0 blob sidecars in blobpool (#35191)\nInline gas deduction to fix a performance regression (#35203)\nFix eth/71 block-access-list empty marker decoding which wrongly disconnected peers (#35286)\nDisable snap sync mode once the pivot block is committed (#35402, #35405)\nSpeed up debugsetHead and reject unrecoverable targets (#35252)\nFix snap sync failing to backfill blocks with missing canonical-hash mappings (#35190)\nReuse ",

This release does not contain a database schema migration or any breaking CLI changes.\n🧩 Partial Data Columns\nLighthouse v8.2.1 includes several fixes for partial data columns (EIP-8136), which are enabled by default on Hoodi and Sepolia.\nThese fixes improve the handling of cached partial data, prevent headers for already-imported blocks from being cached and re-gossiped, and reject received cells that conflict with cells already in the cache.\nUsers running Lighthouse on Hoodi or Sepolia are encouraged to upgrade to benefit from these fixes. To opt out of partial data columns, use --enable-partial-columns false.\nNotable Changes\nFixed several issues in the partial data column cache and gossip implementation.\nOptimised proposer preparation by removing redundant work that triggered getexpectedwithdrawals, particularly around epoch boundaries.\nUpdated dependencies and compiler compatibility.\nUpdate Priority\nThis table provides priorities for which classes of users should update particular components.\n| User Class | Beacon Node | Validator Client |\n|:------------------|:------------|:-----------------|\n| Staking Users | High | Low |\n| Non-Staking Users | High | --- |\nSee Update Priorities for more information about this table.\nSecurity Content\nThis section will be updated with security advisories as they are made public.

Validator client users should review the fee-recipient and graffiti changes below before upgrading.\nThis release also contains substantial Gloas preparation, Fulu data-availability networking improvements, and new standard API support.\nUpgrade Notes\nMandatory fee recipient: Validator clients now refuse to startup when an enabled validator has no suggestedfeerecipient field in validatordefinitions.yml and no global --suggested-fee-recipient fallback is configured. This prevents validator income from being lost accidentally.\nValidator graffiti: Lighthouse beacon nodes now append client version information to user graffiti by default. To opt-out use the --graffiti-append false flag with Lighthouse VC or set graffiti that is between 30-32 bytes long. There is no change in behaviour if you are already using the --private flag for the beacon node.\n💾 Database schema v29: Lighthouse beacon nodes will automatically migrate the database from schema v28 to v29 on startup. A downgrade back to v28 is available prior to the Gloas hard fork, follow the instructions in the Lighthouse Book.\n⚠️ Breaking Changes ⚠️\nValidator fee recipient: Validator clients now refuse to startup when an enabled validator has no suggestedfeerecipient and no global --suggested-fee-recipient fallback is configured. This prevents validator income from being lost accidentally.\nProposer duties: The VC uses the proposerduties v2 endpoint now by default. This is incompatible with beacon nodes that do not support this API. If you are running Nimbus BN or get ERROR Failed to download proposer duties, add --disable-proposer-duties-v2 to your VC flags.\n💻 Breaking Changes for Devs\nMplex will be disabled by default in the next release.\nRemoved non-standard Lighthouse APIs: /lighthouse/analysis/block",
