As of this release, the default block gas limit is set to 60M gas. This is the recommended limit that we, as client authors, feel comfortable with.

CLI commands

• geth snapshot and related commands no longer fail due to not finding the trie journal file. (#32531)
• A regression in geth snapshot dump and geth export-preimages is resolved. (#32650)
• We have added an experimental zkVM 'guest program', keeper, to the source tree. (#32543, #32638, #32736)

RPC

• eth_call and related operations were fixed to not apply the EIP-7825 per-transaction gas limit when executing under Osaka fork rules. (#32641)
• For eth_getLogs and other log filtering operations, it is now possible to configure the number of addresses allowed in the filter using the --rpc.logquerylimit flag. (#32327)
• Starting Geth with the --state.size-tracking option enables collection of precise state size numbers, which can be read using the debug_stateSize endpoint. (#32362)
• The new debug_executionWitness and debug_executionWitnessByHash methods create a block witness for stateless execution. (#32216)

Tracing & ABIGEN

• There is a new CodeChangeV2 hook, with a CodeChangeReason parameter. (#32525, #32535)
• In certain corner-cases related to SELFDESTRUCT, OnBalanceChange was not invoked. (#32526)
• BoundContract in accounts/abi/bind/v2 now exposes an Address method. (#32559)

Core

• The EVM MODEXP precompiled account has seen some optimizations to improve performance for worst-case inputs. We are especially grateful for @GottfriedHerold's work on improving the underlying math/big library. (#32527, #32553, #32568, #32576)
• The blobpool will now perform a migration to the v1 blob proof format around the time of the fork. (#31966, #32577, #32534, #32656, #32716)
• engine_getBlobs has been updated for improved spec compliance and to deal with the conversion of the blob tx proofs. (#32536, #32538, #32578)
• The path-based state database has seen some fixes to prevent database corruption, which could sometimes occur when Geth is terminated abnormally, e.g. by a short stop timeout in Docker. (#32557, #32447)
• All engine API operations, and eth_config, now support BPO-style forks. (#32589, #32615, #32636, #32579)
• This release includes some work towards supporting historical state proofs in the path-based archive node implementation. (#32418, #32523, #32649)
• Pebble stall counter are now correctly reported for each opened database. (#32563)

Networking

• The node discovery iterator was updated to improved geth startup time and reactivity when the node table becomes empty. (#32517, #32518)
• A hang in the 'eth' protocol test suite was resolved. (#32551)

Build

• The KZG proof libraries have been updated to the latest release to fix a vulnerability. Fortunately, the vulnerability would only have become usable after the Osaka fork, so there is no risk for users of current versions. (#32640, #32639)
• go-ethereum now requires Go 1.24 or later. (#32584, #32598)
• This release is built with Go 1.25.1 (#32593)
• execution-spec-tests has been bumped to v5.1.0 (#32592, #32742)
