Talaria (v1.14.6)

Geth v1.14.6 is a maintenance release, but it does ship with the experimental witness building validation code used in @​karalabe's "cross validation" proposal. Note that the engine API part is not included in this release.

---

Shipped features:

• Add stateless witness builder and (self-)cross validator (#29719, #29807, #29970, #30024)
• Set a 2KB hard limit for p2p handshake messages (#30029)
• Improved display of database statistics (#29948)

Shipped bugfixes:

• Fix issue in which the beacon root contract balance would not be saved in developer mode, causing an error on restart (#29963)
• Fix shutdown crash when geth runs in blsync mode (#29946)
• Fix data races in snapshot access (#30001, #30011)
• Fix out of bounds access in json unmarshalling (#30014)
• Add missing lock in peer discovery (#29960)

Bothros (v1.14.5)

Geth v1.14.5 is a hotfix release that addresses a regression introduced in v1.14.4, which prevented the node from discovering other peers in certain networking setups (#29944). It is otherwise identical to v1.14.4.

---

Geth v1.14.4 in a usual maintenance release, but it does ship a 5-7% block import speed improvement. Furthermore, v1.14.4 also finally includes an Ether supply live tracer, that you can enable via --vmtrace supply. Also please note, the default value for miner tip enforcement was dropped from 1 gwei to 0.001 gwei (block producers can change this via --miner.gasprice).

Shipped features:

• Reduce the default required minimum miner tip from 1 gwei to 0.001 gwei to cater better for network conditions (#29895).
• Load trie nodes concurrently with trie updates, speeding up block import by 5-7% (#29519, #29768, #29919).
• Introduce an Ether supply tracker as a live chain tracer (#29347).
• Implement Verkle stateless gas accounting (EIP-4762) (#29338).
• Optimise trie dirty tracking to reduce disk loads a bit (#29731).
• Ensure the beacon chain roots system contract is deployed in dev mode (#29655).
• Add an additional snap sync check for data validity before inserting into the database (#29485).
• Improve the discovery protocol's node revalidation (#29572, #29864, #29836).
• Continue working towards pathdb support in archive mode (#29530, #29924).

Shipped bugfixes:
