Geth v1.9.19 is our regular biweekly maintenance release. Apart from the numerous bug-fixes however, it also ships a more deterministic transaction sort order during mining (FIFO). The goal is to reduce front-runner spam which abused miner randomness for transactions at the same price level.
- Sort same-priced transactions by arrival time during mining to reduce front-running (#21358).
- Persist the trie read cache on shutdown to speed up warmup time after a reboot (#20391).
- Swap out the block fetcher of
les/xto use the same mechanism as
- Support setting custom HTTP headers on RCP clients e.g. for authentication (#21392).
- Refactor node lifecycle management, merge GraphQL onto HTTP endpoint (#21105).
enodeID of a node too when doing an ENR dump via
- Trim the build paths to avoid leaking builder infos into the binaries (#21374).
- Limit concurrent UPnP requests to avoid crashing certain routers (#21390).
- Fix a potential data corruption by leaking out txpool internals into the miner (#21159).
- Avoid a light server doing EVM calls during handshake while it's syncing (#21425).
- Fix the trie clean cache size calculation if snapshots are disabled (#21416).
- Revert an optimization regression in the JUMPDEST analysis (#21411).
- Fix EIP 712 structured data signing corner cases (#21306, #21307).
- Fix round-trip time calculation in the downloader (#21427, #21429).
- Fix a panic in ethstats on the Görli stats page (#21404, #21434).
- Fix a hang in the initial fast-sync's state sync phase (#21433).
- Fix graceful LES server shutdown (#21426).
Note, if you were using GraphQL previously, it was moved to the HTTP RPC endpoint. The old
--graphql.port flags will not work any more. You might need to adjust your TOML config files accordingly too.
