Giddy Gadgets (v1.12.0)

This is a stable release representative and inclusive of the progress of the previous two release candidates tags and publications.

• Merge ethereum/go-ethereum@v1.10.1 (#348).
• Merge ethereum/go-ethereum@v1.10.2 (#357).
• Merge ethereum/go-ethereum@v1.10.3 (#378).
• Fix eth_getBlockByNumber and Uncle methods' nullable field handling (#333, #341).
• Add activation block numbers for Ethereum Classic's Magneto hard fork per ECIP-1103 (#385).
  • 3_985_893 on Mordor Classic PoW-testnet (estimated June 2nd, 2021)
  • 4_368_634 on Kotti Classic PoA-testnet (estimated June 9th, 2021)
  • 13_189_133 on Ethereum Classic PoW-mainnet (estimated July 21st, 2021)
• Add protocol configuration support for chain configuration schemas (#384).
• Add stateDiff tracer, which is compatible with OpenEthereum (#345).
• Add EVMC Version 7 support for external EVMs (#329). This version is compatible with EVM features through Ethereum's Istanbul fork upgrade.
• Add generated cross-client tests for ETC's Magneto fork, improving CoreGeth's generators/fillers along the way. (#353)
• Remove echaindb command, replaced by the new geth db command (#366).
• Remove unresponsive bootnodes (#339).
• Refactor tracer stuff on top of go-ethereum's refactor (#355).
• Docs revised to support subscription based methods, and now include a starter tutorial for setting up a private network (#356, #330).

Please be advised that the merges from ethereum/go-ethereum's 1.10+ series include significant and myriad changes; support for eth/64 and below is dropped, commands are removed (eg. geth dump), APIs change (eg. eth_gethashrate, eth_protocolVersion), and many deprecated CLI flags are removed (eg. --rpc, --debug, --pprofport, and --cpuprofile, et al.). If your use case is sensitive to these domains, we strongly encourage you to review those release notes as well.

Mindfish (v1.11.22)

• Merge ethereum/go-ethereum@v1.9.25 (#272)
• Change default extraData prefix for mined blocks to CoreGeth (from geth) (#310)

Aganippe (v1.11.21)

• Add --ecbp1100.nodisable as a way to disable ECBP1100 auto-shutoff mechanisms (low peers and stale head) (#303).
• Add a new RPC API subscription method newSideBlocks, creating a subscription to side-chain import events (blocks written but not considered canonical) (Websocket, IPC, and inproc only) (#293).
• Add OpenRPC rpc.discover schema compliance tests (#295).
• Refactor cmd/faucet to fix some bugs and add some features, including...
  • Add faucet --attach flag to allow you to run a faucet on top of an existing node instance (instead of only on top of a dedicated light client) (#269).
  • Add faucet --syncmode=[full|fast|light] flag to decide the syncmode of a faucet-managed node (instead of only a default LES client) (#268).
  • Migrate the faucet's node data directory (if any) from <datadir>/MultiFaucet to <datadir>/CoreFaucet. The data migration logic should handle this automatically for you, but if you're using a custom setup you may need to reconfigure (#279).
• Fix a geth console bug where --jspath and --preload together would generate a bad path (#274).
• Remove cmd/puppeth to reduce footprint and trim feature-creep (#270).
• Finally set up a documentation site, check it out! https://etclabscore.github.io/core-geth 📕 🎉

Carnus (v1.11.19)

Core-Geth v1.11.19 is a security release critical for mining nodes addressing an incorrect seedHash being returned by makeWork/getWork in post-ECIP1099 epochs (#236).

We recommend upgrading to the artifacts of this release or building from this tag or later prior to the Thanos hardfork for ETC Mainnet (block 11.700.000, ETA 28 Nov. 2020), and immediately for the Mordor test network.

A reminder: If you are building geth from source, please ensure you are building with Go v1.15.5 or above. We recommend using the latest Geth version, but if you are not mining and cannot upgrade to core-geth v1.11.19, please rebuild your current version with Go v1.15.5.

Hyacinth (v1.11.18)

Core-Geth v1.11.18 is a security release. It is built with Go v1.15.5, fixing CVE-2020-28362, which has a critical impact for Ethereum and Ethereum Classic. (See https://github.com/ethereum/go-ethereum/releases/tag/v1.9.24).

We recommend everyone to upgrade to the artifacts from this release or rebuild with Go 1.15.5.

If you are building geth from source, please ensure you are building with Go v1.15.5 or above. We recommend using the latest Geth version, but if you are not mining and cannot upgrade to core-geth v1.11.18, please rebuild your current version with Go v1.15.5.

To manually update a Docker image to Go v1.15.5 (before the base image is updated), please see the instructions provided at the above-linked ethereum/go-ethereum's release notes.
