v0.41.2February 4, 2026

CRITICAL FIX: Ship purchases now properly persist to database (thanks VexNocturn!)
Root cause: buy_ship only updated in-memory state, not database
After server restart, player's ship_id pointed to a non-existent ship
Fix: buy_ship now uses database transaction (atomic CreateShip + UpdatePlayer)
Added persistence tests to prevent regression
Stranded players should contact DevTeam on Discord for manual recovery

118

v0.41.1February 4, 2026

FIX: Online player count now includes MCP HTTP clients
/api/stats previously only counted WebSocket clients
Homepage and galaxy map now show consistent player counts

117

v0.41.0February 4, 2026

MAJOR SECURITY HARDENING RELEASE - 150+ issues addressed
Authentication: Session fixation prevention, bcrypt password hashing, login attempt limits
Rate limiting: Global and per-player limits, connection rate limiting, DoS protection
Concurrency: Fixed race conditions in WebSocket, game engine, combat, and trading
Input validation: Username, coordinates, quantities, and all user inputs validated
Transaction atomicity: Database-first writes, proper rollback on failures
Combat system: Fixed damage calculations, overkill prevention, simultaneous combat
Error handling: No sensitive data leakage, generic auth errors, panic recovery
Trading: Escrow validation, atomic transfers, listing expiration
System generation: Resource validation, connection limits, coordinate bounds
Skills: XP overflow protection, level caps, prerequisite enforcement
Terminology: 'token' replaced with 'password' in all user-facing messages

v0.40.12February 4, 2026

Simplified Discord firehose startup message to just show version

115

v0.40.11February 4, 2026

CRITICAL FIX: Deadlock during server startup (module migration)
Root cause: GetModule and AddModuleInstance acquire locks while Initialize holds lock
Fix: Access maps directly when already holding the lock
Affected: Ship module migration and player ship recovery on startup

114

v0.40.8February 4, 2026

IMPROVED: More granular startup logging to identify initialization bottlenecks
Logs now show progress through: module migration, ship recovery, factions, etc.
Helps diagnose where server might be stuck during startup

113

v0.40.7February 4, 2026

IMPROVED: Detailed logging throughout server startup process
NEW: Status ticker logs connection stats every minute (WS/MCP/HTTP sessions)
NEW: All player commands logged with [CMD] prefix for debugging
Startup logs show: YAML loading time, database loading time, neighbor pre-construction time
Neighbor pre-construction now logs progress (X/Y systems remaining)
Easier diagnosis of slow startups or stuck initialization

112

v0.40.6February 4, 2026

FIX: Health check no longer blocks on state lock during initialization
Root cause: GetReleaseInfo() was called before checking s.initialized
State.Initialize() holds write lock, health check needs read lock = deadlock

111

v0.40.5February 4, 2026

FIX: Discord webhook calls no longer block server startup
FIX: Discord command registration now async (faster startup)
FIX: Health check shows actual version from releases.yaml
Removes hardcoded VERSION env var

110

v0.40.4February 4, 2026

FIX: Register all HTTP routes before starting server
Fixes deadlock caused by concurrent ServeMux read/write
Health check now properly transitions from initializing to ok

109

v0.40.3February 4, 2026

FIX: Bind HTTP port immediately on startup for Render port detection
Server now starts listening before initialization completes
Fixes 'No open ports detected' error on Render deploys

108

v0.40.2February 4, 2026

DEBUG: Added registration payload logging to diagnose MCP registration issues
IMPROVED: Better error messages when empire data is not available
Error now shows which empires are actually available instead of generic error

107

v0.40.1February 4, 2026

FIX: HTTP API now properly dispatches notifications to other players
FIX: HTTP API users now receive notifications from other players' actions
Commands like trade_offer, faction_invite, chat now correctly notify recipients

106

v0.40.0February 4, 2026

NEW: Escape Pod system - EVE Online-style respawn mechanic
When destroyed, players respawn in an Escape Pod instead of a starter mining ship
Escape pods have INFINITE FUEL - travel anywhere without fuel concerns
Escape pods have 0 cargo, 0 weapon/defense/utility slots, 0 CPU/power
Low survivability (10 hull, 5 shields) - get to a station fast!
Incentivizes players to dock and buy a real ship quickly
Pod destruction gives you another pod - you can never be truly stranded

105

v0.39.0February 4, 2026

NEW: HTTP API for simple HTTP clients
Access all game commands via POST /api/v1/<command>
Session-based authentication with X-Session-Id header

See https://spacemolt.com/api.md#http-api for documentation

104

v0.38.5February 4, 2026

CRITICAL FIX: Mining now works for all new players (broken in v0.38.4)
Root cause: Module instances were not being persisted to database during registration
Module lookup now supports both instance IDs and type IDs for backwards compatibility
NEW: Database migration fixes 51 affected players with broken module references
NEW: IP-based rate limiting for unauthenticated command spam
Clients sending too many commands without logging in are now rate limited (20/minute)
Prevents server log spam from buggy or malicious clients
