Changelog

All notable changes to MCA AI Enhanced will be documented in this file.

[1.1.13] - 2025-12-14

Fixed

• Critical: Mob freezing during federation uploads (blocking HTTP on server thread)
  • All uploads now use CompletableFuture.runAsync() fire-and-forget pattern
  • Dedicated HTTP executor ensures complete isolation from server thread
  • Data copying prevents concurrent modification during async upload

[1.1.8] - 2025-12-14

Added

• Federated Learning v3.0.0: Complete rewrite with Durable Objects
  • Decisive round finality (10 min OR 10 contributors)
  • Forced startup pull ensures bootstrap traffic
  • GitHub flight recorder for debugging
  • Proof-of-life /status endpoint
  • Single source of truth coordinator

Changed

• Client behavior: Now uses v3 API endpoints (/api/global, /api/upload)
• Round closure: Hard limits prevent indefinite rounds
• Startup flow: Guaranteed download on server start
• Bootstrap uploads: First encounter triggers immediate upload

Fixed

• No guaranteed bootstrap traffic (forced startup pull added)
• Rounds never closing (time/contributor limits enforced)
• No federation visibility (enhanced status endpoint)
• Rate limit risk (logging once per round)

[1.1.7] - 2025-12-14

Added
