Scheduled

We are upgrading our Litecoin Mainnet and Testnet infrastructure to v0.21.5.6. This is an urgent maintenance release that strengthens MWEB transaction, block, and P2P-service validation. A soft-fork consensus change activates at mainnet height 3,154,440 that will reject MWEB blocks containing kernels signaling a pegout with an empty pegout list.

During the maintenance window, brief interruptions to RPC availability may occur.
