Changelog

1.6.0

Social/QoL feature drop on top of the 1.4.0 anti-cheat + admin toolkit (everything from 1.4.0 is still here).

New

• Raid event alerts. When a random event / raid begins, pauses (no players in the area), resumes, or ends, ServerGuard posts to the public Discord channel using the actual in-game event name (e.g. "The Horde Is Attacking", "You Are Being Hunted") instead of the internal code name, with world coordinates.
• Player shout logging. Player shouts (/s) are forwarded by the companion and posted to the public Discord channel (chat can no longer be observed server-side, so the companion reports them).
• Cheat-item removal. On login, non-admin players have configured cheat items stripped from their inventory (SwordCheat, SledgeCheat by default). Configure via enableCheatItemRemoval and cheatItems in settings.yaml; admins are exempt.

Companion

• Requires companion plugin v1.6.0 (adds the optional title-screen Quick Login panel — see the client changelog).

1.4.0

Big feature drop — anti-cheat, admin tools, and Discord cleanup.

New: anti-cheat

• Devcommands gate. Players can't type devcommands, god, fly, spawn, etc. on your server. Vanilla cheat commands are blocked client-side and reported to you.
• Animation-cancel gate. Blocks the classic emote / sheathe attack-cancel exploit (used to spam secondary attacks faster than vanilla allows).
• Movement-speed sanity check. Flags players moving impossibly fast across the ground.
• Inventory validation. Flags unknown items and over-sized stacks server-side.
• Skill-level cap. Catches players with skill levels above the cap (default 100 + tolerance).

New: forensic tools

• Build/destroy heatmap. Every piece place / destroy is logged to a daily CSV with attribution, including creature destroys (Troll smashes your base = logged as "Troll").
• Death log. When a player dies, an entry is posted to your public Discord with the cause (creature name, PvP killer with SteamID, or environmental cause like "drowned"/"fell").
• Modset fingerprint. Each server publishes a short hash (e.g. 8ce8906e) that uniquely identifies its modpack — players can verify they're connecting with the matching pack.

New: admin console commands

Press F5 to open the console, then type sg help. You'll get a moderation toolkit without leaving the game:

• sg status, sg reload, sg modset, sg selftest
• sg whois <name>, sg violations, sg pardon, sg kick
• sg build at <x> <z> / by <name> / today — query the heatmap
• sg destroyed at|by|today and sg placed at|by|today — filter to destroys or placements only

Discord channel split

• Public channel = community-friendly events only: joined, left, kicked, died. Safe to share with all players.
• Admin channel (new) = curated moderation events: violations, config reloads, admin command audit, daily summary. Set discordWebhookUrlAdmin in settings.yaml.
• Admins are hidden from the public channel. Their join/leave/death events go to the admin channel only.
• Daily summary posts a one-paragraph digest each UTC midnight (joins, leaves, kicks, bans, top kick reasons).

New: ping / latency log

Optional admin-only feature: posts each player's first ping after join and their session-average on disconnect. Helps spot VPN / proxy users. Default off.

Other improvements

• Self-test on boot. Smoke-tests config (HMAC, webhook URLs, file permissions). Alerts the admin channel on any failure.
• Player death cause messages. Now show creature names, killer SteamID for PvP, or environmental cause (burned / drowned / fell / etc.).
• Per-rule "counts as violation" toggle so you can tune which rules can lead to auto-ban vs which are just informational.
• Hot-reload of all config files — edit settings.yaml / admins.yaml / allowed_mods.yaml and the server picks it up within a second.
• Mod-set fingerprint mismatch detection. When a player connects with the right mods but different versions, the admin channel notes it.

Bug fixes

• Admin connection event now shows up properly.
• Hammer-removed pieces now log correctly with attribution.
• Build positions now record the real world coords (not the prefab origin).
• Several Mono compatibility fixes for current Valheim builds.

1.3.0

Initial public release. Mod allowlist with HMAC-signed attestation, per-peer auto-ban for repeat violations, hot-reload of configs, Discord webhook integration.
