Scheduled

We are upgrading our TON Mainnet infrastructure to v2026.05.

This release includes networking improvements (block candidates sent over a dedicated block-sync overlay), collation, validation, and block-application performance optimizations for validators and liteservers, TVM v14, and the removal of legacy code (catchain, adnl-proxy, rldp1).

During the maintenance window, customers may experience intermittent disruptions to RPC availability as nodes are rotated through the upgrade process.

RPC Changes: get_shard_client_state — new liteserver method added, exposing shard client state to clients.
