Scheduled

We are upgrading our Polkadot Mainnet infrastructure to polkadot-sdk stable2606 and REST API v0.1.5.
These are patch releases containing bug fixes and improvements:
The SDK release includes XCM executor hardening, BEEFY MMR alignment fixes, XCMP queue storage optimization, and Aura slot duration corrections.

The REST API release relaxes SS58 prefix validation on account read endpoints to accept addresses with any SS58 prefix. No breaking changes or state migrations are required.

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