Logos Chat advancing with signature types, Account struct, and logos-delivery integration in chat-cli; delivery module tested as full service node on logos.dev fleet.

Storage

status-go PR #7332 merged; hidden services over Mix spec finalized with LIONESS and key-blinding signature scheme; NAT Traversal advancing with autorelay and DHT fixes.

AnonComms

de-MLS multi-steward implementation progressing with voting/freeze rework, self-leave bug fix, and steward list integration with GroupSync.

Messaging

Relay validator registration and sync filter fixed; memory leaks in nim-ffi resolved; Reliable Channel API and SDS-Repair work continuing.

Storage

nim-poseidon2 improved for Logos Blockchain compatibility; Nim updated to 2.2.10; UDP keepalive and NAT-type detection experiments underway.
