sei-protocol/sei-chain v6.6.4 on GitHub

ℹ️ This is NOT a mandatory upgrade for validators. There is no coordinated halt or governance proposal. Nodes can upgrade whenever they like with a normal binary swap and restart. ⚙️

v6.6.4 is a small patch release on top of v6.6.3 🚀, aimed at operators running nodes in freeze mode 🧊 (#3978). A frozen node halts one block below its freeze height and never processes another block. On v6.6.3 the EVM HTTP and WS servers only start after a block is processed, so a frozen node that restarted came back with its data and Tendermint RPC fine but its EVM RPC stuck offline 🔌. This release fixes that (#4448). On startup a frozen node now initializes the app from its last block header, which starts the EVM servers just as processing a block would ✅.

🎯 Who Should Upgrade


🧊 Frozen historical RPC operators	Strongly recommended: EVM RPC comes back after a restart
🖥️ RPC / full-node operators	Optional: nodes not in freeze mode behave exactly as before
🛡️ Validators	Optional: no state-machine or consensus-breaking changes
⏱️ Downtime	Just a node restart; no coordinated halt

What's Changed

Initialize app from last header on frozen restart for v6.6 by @masih in #4448
