Jotunn
Jotunn 2.29.2 rebuilt for Valheim 1.0.7 by The Reef until the Jotunn team ships its own 1.0 build. MIT, source linked. Same plugin GUID as ValheimModding-Jotunn: the higher version loads. Remove it once upstream is out.Jotunn 2.29.3 (The Reef build)
Jötunn, the Valheim Library, is the work of the JotunnLib Team — MIT licence, source at https://github.com/Valheim-Modding/Jotunn. All credit for the library goes to them.
This package is not an official Jötunn release. It is upstream v2.29.2 (commit 3a3549d4) rebuilt against Valheim 1.0.7 with five small fixes, published by The Reef so its players keep the mods that need Jötunn (AdvancedPortals, EquipmentAndQuickSlots, AdventureBackpacks) until the Jötunn team ships a 1.0 build of their own.
Why it exists
Valheim 1.0 renamed PieceTable.m_availablePieces to m_availablePiecesByCategory and switched the VisEquipment item setters to int hashes. Jötunn 2.29.2 then throws on every frame on the client (hammer and placement dead) and fails its initial data sync at every join. Both were seen and fixed on The Reef's test server on 2026-09-09.
What changed against upstream 2.29.2
Five files; the full diff is in CHANGELOG.md.
Managers/PieceManager.cs— readm_availablePiecesByCategoryUtils/ExtEquipment.cs— theVisEquipmentprefixes take(int itemHash)Utils/GameVersions.cs— the network version constantUtils/UndoActions.cs—Poke()Main.cs— version 2.29.3 and one log line naming this build
Version numbering and removal
Same plugin GUID as ValheimModding-Jotunn. BepInEx loads the highest version of a GUID, so 2.29.3 takes over from the 2.29.2 your other mods depend on; you keep both installed and nothing else changes. Uninstall this package as soon as the Jötunn team publishes a 1.0-compatible release.
