This release covers quite a lot of time, and has many changes across the codebase. In particular; changes in tracing and account management, optimizations in database, trie and evm, and, as always bugfixes.

This release removes the personal RPC namespace. It was already previously deprecated, and has not been accessible by default for nearly two years. We also removed the --unlock command-line parameter, with a view towards removing key/account management from the geth binary.

• Key management:
  • Remove --unlock command line flag from geth (#30737)
  • Remove personal RPC namespace (#30704)
• Builds:
  • RISC-V docker images (#30739)
  • ppa-builds for ubuntu 24.10 (#30580)
• Tracing:
  • invoke OnCodeChange-hook on selfdestruct (#30686, #30497)
  • improvements to flatCallTracer (#30539)
  • invoke tx-end hook in runtime helpers (#30711)
  • disableCode and disableStorage options for prestateTracer (#30648)
  • tracing of system calls (#30666)
  • Change to how chainconfig is passed to tracers (breaking change) (#30540)
  • add GetTransientState method to StateDB interface (#30531)
• Signing:
  • improved support for EIP-712 array types (#30620)
  • non-legacy transactions support for ledger wallets (#30180)
• Bugfixes:
  • Set basefee for AccessList based on given block, not chain tip (#30538)
  • Multiple issues in benchmarks (#30667)
  • Fix bug with resolving a payload (#30615)
• Database optimizations
  • Run pebble in non-sync mode (#30573, #29792). This change makes quite a big difference on certain OS:es, particularly MacOSX/Darwin, where it has been noted that fsync is notoriously slow.
  • Use to increasing level sizes (#30602), This change makes pebble use larger files, reducing the number of files from 160K to 10K.
• Assorted:
  • Make jwtsecretflag expand tilde
  • Work on verkle (#30672)
  • Work on EIP-7002 and EIP 7251 (#30571)

  • Validation of EOF containers (#30418)
  • More helpful responses for rejected transactions (#30715)
  • Work on cross-execution witness (#30698)
  • EVM speed optimizations (#30662, #30629)
  • Reduce peak memory usage during reorg (#30600)
  • Speed up trie commit via concurrent workers (#30545)
  • Fuzzing improvments (#30585)
  • Implement new engine_getBlobsV1 API method (#30537)
