1.0.4

• fixed a Visual Studio CPS LimitedFunctionality project-tree error by removing the imported Thunderstore.targets file from the SDK default None item list while keeping it as an explicit MSBuild import
• fixed the 1.0.4 source build against the existing Unity reference set by removing an unnecessary Canvas.ForceUpdateCanvases() call from connection-error layout normalization
• fixed optional client-side CCS consumers remaining in a fail-closed replica state when the connected server does not provide that mod; after successful PeerInfo, the instance now returns to local config ownership without raising InitialSyncCompleted
• classified version-check failures as a missing handshake, missing protocol metadata, protocol mismatch, invalid version data, or a specific mod-version range mismatch
• changed connection-rejection diagnostics to unconditional error logs so disconnect causes are recorded even when debug logging is disabled
• added the remote client identifier, reported Conditional Config Sync package version, protocol, and handshake timing to version-check logs
• kept received version-handshake state per peer so simultaneous connections cannot overwrite the diagnostics used for another client
• added an optional trailing Conditional Config Sync package version to the compatible protocol 1 handshake without changing the wire protocol version
• sends one bounded structured English disconnect report with a report ID and explicit reason codes before the vanilla version error
• associates pending disconnect reports with one client connection attempt, preserves them across the failed ZNet shutdown, and clears them after success, display, a new attempt, or timeout
• appends CCS diagnostics to the existing Valheim error text before Jotunn and ServerSync process it, preserving Jotunn's separate compatibility window
• only augments the connection error when an explicit report belongs to the current CCS rejection, avoiding speculative CCS text for unrelated ErrorVersion failures
• normalizes the vanilla connection-error layout one frame later without repeatedly moving the confirmation button
• records malformed version-handshake packages and improves reporting when a required remote mod did not process the shared version RPC

1.0.3

• fixed initial handshake buffering so vanilla PlayerList and AdminList are delivered after PeerInfo, preserving LocalPlayerIsAdminOrHost() and the initial player list

1.0.2

• exposed a structured policy-control availability state so configuration UIs can distinguish a missing compatible server session from missing administrator access
• renamed the public package metadata type from PluginSelfInfo to PluginInfoCCS
• added public read-only effective synchronization metadata for configuration UIs and diagnostics
• exposed normalized default ownership, effective ownership, policy initialization, hidden state, and effective ownership overrides
• effective ownership falls back to the normalized mod default until policy state is initialized
• added an administrator-authorized API for toggling individual Conditional settings between server and client ownership
• policy changes requested by compatible configuration UIs are persisted as minimal exact-setting rules in SyncPolicy.cfg
• fixed-mode settings and unauthorized clients cannot use the policy toggle API
• compatible servers advertise policy-control support through an optional extension of the existing lock-exemption entry
• no network protocol changes
• fixed stale configuration-manager permissions by failing closed during connection and re-evaluating read-only metadata after initial synchronization
• added a high-priority runtime guard that restores protected BepInEx config values before an unauthorized change notification can be processed
• removed local fallback presence from write authorization; effective ownership, initial sync, admin status, server lock, and explicit unlocked-update opt-in now determine writability
• changed AllowClientConfigUpdatesWhenUnlocked to a secure disabled-by-default opt-in for non-admin clients
• hardened server-side client update validation with ready-peer checks, per-entry ownership and permission checks, duplicate/unknown/trailing-data rejection, and all-or-nothing parsing before application
• client updates no longer send authoritative config state; matching legacy state claims remain accepted only as non-authoritative compatibility validation
• stopped forwarding original client packages and now redistribute canonical values and server-computed state to every client, including the initiator
• added rate-limited authoritative correction or full resynchronization after rejected client updates
• added explicit accepted/rejected client-update audit logs with sender and authorization state
• ensured an already registered locking entry is upgraded to protected always-server-controlled state
• stabilized the public core assembly identity at 1.0.0.0 for compatible 1.x releases while retaining current file and informational versions
• renamed the policy reload summary tag from [Policy] to [SyncPolicy]
• added comprehensive architecture, rationale, compatibility, security, test, and release context in PROJECT_CONTEXT.md

1.0.1

• renamed PluginInfo class to resolve conflict with BepInEx class with similar name

1.0.0

Initial release of Conditional Config Sync, a standalone shared dependency for Valheim mods.

For players

• Provides synchronization infrastructure for mods that declare Conditional Config Sync as a dependency.
• Adds no gameplay content, items, UI, or standalone configuration of its own.
• Can run alongside Jotunn and mods that use ServerSync without replacing, modifying, or intercepting either library.
• Keeps synchronization fixes centralized, so dependent mods can receive runtime fixes by updating this package.

For server administrators

• Provides three setting ownership modes: AlwaysServerControlled, Conditional, and AlwaysClientControlled.
• Supports exact-setting and whole-section ownership rules through ConditionalConfigSync.SyncPolicy.cfg.
• Supports exact-setting and whole-section visibility rules through ConditionalConfigSync.HiddenConfigs.cfg.
• Loads policy during server startup and applies stable file changes at runtime on the Unity main thread.
• Provides a protected locking setting with administrator exemption and non-admin write validation.
• Includes status, policy_reload, policy_validate, and policy_dump commands for policy operation and diagnostics.
• Synchronizes regular BepInEx configuration values and runtime custom values with bounded payloads, fragmentation support, and explicit rejection errors.
• Restores local client values and ownership state correctly when policy changes or the server connection ends.

For mod authors

• Distributed as a standalone BepInEx hard dependency; reference ConditionalConfigSync.dll instead of embedding or ILRepacking a private copy.
• Provides familiar ConfigSync, SyncedConfigEntry, CustomSyncedValue, and VersionCheck APIs with XML IntelliSense documentation.
• Lets each mod explicitly require a compatible copy on the remote client or server through the documented ModRequired option.
• Supports one-call bind-and-register overloads that assign ownership before registration.
• Provides fixed and policy-controlled config modes for shared mechanics, client-local presentation, and administrator-selectable behavior.
• Provides state-like and sequenced custom values, priorities, equality comparers, explicit assignment modes, and ISerializableParameter support.
• Uses TOML conversion for regular BepInEx entries and length-prefixed package entries for safer parsing and forward handling.
• Provides lifecycle, policy, lock, connection-reset, rejection, and initial-sync events.
• Supports late registration, automatic resynchronization, and explicit RequestFullSync().
• Isolates failures from individual SettingChanged handlers so remaining package entries can still be applied.
• Uses an independent numeric wire protocol and requires an exact client/server protocol match.
• Includes release SHA-256 hashes for both runtime DLL files.
