v1.4.0 - 2025-05-05

This is Charon's v1.4.0 release. Feedback is welcome and appreciated, please use github issues or discord if you have trouble with this release.

Notable user-facing features shipping in this release include:

• Charon's --graffiti and --graffiti-disable-client-append flags (to disable client version packing), allow operators to set custom graffiti strings to be attached to block proposals their node makes.
• Charon's --publish (and --publish-address) flag in the test command, allows operators to opt into publishing their test data. This data assists in the ongoing improvement of Charon's performance.
• Charon can now verify Safe{Wallet} signatures (and other EIP1271 smart contract signatures) on the dkg and run commands with the addition of the --execution-client-rpc-address flag.
• Users can now prepare DKG invitations using the DV Launchpad from the charon create dkg command, by adding --operator-addresses (instead of --operator-enrs) and the --publish flag. (Using the DV Launchpad comes with standard terms of use.)
• This release also includes our first iteration of pre-built binaries for Charon. Use them with caution for the time being.
