BepInExPack Valheim

Changelog

5.4.2351

Logging

Changed

• Every plugin line now has the GUID after the name, e.g. Loading [AzuExtendedPlayerInventory 2.5.1] (Azumatt.AzuExtendedPlayerInventory). Two mods with the same name are easy to tell apart now, and log parsers still read the bracketed part the same way as before.
• Chainloader startup complete now ends with counts, e.g. (41 loaded, 2 skipped, 1 failed).

Fixed

• Valheim Version: line actually shows up in LogOutput.log now like it used to.
• When the same GUID is installed twice, the skip warning shows where both copies are (relative to BepInEx/plugins) so you know which one to delete. If both copies are the same version it says it's a duplicate instead of claiming a newer version exists.

Doorstop

Changed

• libdoorstop_x64.so is now the stock UnityDoorstop 4.5.0 build, byte-for-byte from the upstream release. It only needs glibc 2.7 or newer, so Linux servers older than Ubuntu 22.04 and Debian 12 can load it too. winhttp.dll and the macOS lib are unchanged.

5.4.2350

Updated to BepInEx 5.4.23.5 from 5.4.23.3.

Plugin metadata

Fixed

• Semver version strings now load. A plugin declaring something like [BepInPlugin("com.example.mod", "My Mod", "1.1.0-beta.2")] got thrown out at startup with Skipping type [X] because its version is invalid. buried in the log and nothing else to go on. The version now gets split at the first - or + so the numeric part parses, and the suffix is kept in a new BepInPlugin.VersionExtra property so it still shows up in the log line and in config file headers.

UnityLogListener

Changed

• We had our own Unity 6 fix and upstream added theirs, so both were sitting in the same constructor doing nearly the same job. It's one block now: resolve UnityEngine.UnityLogWriter from the loaded CoreModule, try the public WriteStringToUnityLog(string), fall back to the private WriteStringToUnityLogImpl(string), then to the old stub for pre-Unity 6 games. Nothing behaves differently, there's just one path to read instead of two.

Picked up from upstream

Fixed

• The chainloader no longer dies on builds that have had Unity's log callbacks stripped out of them (#1392).
• XTermFix and ConsoleSetOutFix are wrapped now, so when they throw on macOS the preloader carries on instead of taking BepInEx down with it (#1288).

Notes

• Doorstop stays at 4.4.0 on purpose, and that includes our libdoorstop_x64.so built against glibc 2.34 for Ubuntu 22.04 and Debian 12. Nothing on the native side changed this release, winhttp.dll included.
• Apple Silicon still needs the game forced through Rosetta. There's a macOS section in the README now covering it.
• The .pdb files are gone from BepInEx/core. Upstream stopped shipping them and we had no reason to keep them.

5.4.2333

UnityLogListener

Fixed

• Unity 6 compatibility: We now bind directly to Unity’s real UnityEngine.UnityLogWriter from UnityEngine.CoreModule instead of our local stub. This fixes cases where the listener failed to start on Valheim 0.221.3 (Call to Arms PTB) with Unity 6000.0.46f1, which showed:

  • [Error : BepInEx] Unable to start Unity log writer

Hardening

• Only hook a method that exactly matches WriteStringToUnityLog(string) and probe it safely before using it.
• If the Unity 6 method isn’t available, we fall back to the legacy stub (older Unity versions continue to work).
• Keep the existing guard to avoid double-writing console output; the Logging.LogConsoleToUnityLog config still behaves the same.

Preloader

Changed

• Log Valheim version earlier: Print the game version (with network version) before the chainloader runs, so the info is captured even if the game crashes during early startup.

---

5.4.2332

Changed

• Updated libdoorstopx64.so to be correctly named libdoorstop_x64.so

---

5.4.2331

Changed

• Updated libdoorstop_x64.so in the BepInEx package to target glibc 2.34 by compiling against Ubuntu 22.04.

  • This restores compatibility with Ubuntu 22.04, Debian 12, and other Linux distributions using glibc 2.34 or newer.
  • Previous builds were compiled against newer glibc versions (e.g., 2.38), which caused runtime failures on older but still-supported systems.

Compatibility Notes

• Systems using Debian 11 or older (glibc < 2.34) are no longer supported.

• Containers like lloesche/valheim-server-docker must be updated to a base image that provides glibc 2.34+.

• If you're still encountering issues after updating, verify your runtime glibc version using:

  ldd --version
  

Script Changes

• start_server_bepinex.sh updated to correct vars

Special shouts

• Thank you to Arrowmaster for testing and help given.

5.4.2330

Plugin Changes

• Valheim.DisplayBepInExInfo.dll is no longer included by default. This plugin is now offered separately on Thunderstore for those who still want it here. It provided plugin counts in the main menu and in-game access to BepInEx log output via the console.

  ⚠️ This change only affects new installs and new profiles. Existing setups are unaffected. For debugging, it’s now recommended to either:

  • Use the console window that launches alongside the game, or
  • Directly open the BepInEx/LogOutput.log file.

Documentation

• The README has been updated with more relevant, up-to-date information.
• Due to limitations on Thunderstore descriptions, any live updates or important notices for this pack will be posted on the Wiki tab. If you have something that should be added, contact one of the maintainers.

Upstream Updates

• Updated BepInEx from 5.4.22 to 5.4.23.3.
• Preloader updated to align with this BepInEx release.
• Doorstop upgraded to v4.4.0 as part of the upstream sync.

Startup Script Improvements

• Replaced the official BepInEx start_game_bepinex.sh with a community-tested version by Arrowmaster. This version provides better handling of Steam launch arguments, regardless of their order.
