0.6.0 - 2026-04-21

Changed

• Bumped livekit_client dependency to ^2.7.0 (fixes build failures on Android and iOS)
• Requires Flutter >=3.38.0 due to transitive meta ^1.17.0 requirement

0.5.1 - 2026-04-13

Re-release of 0.5.0 with the version correctly bumped in package source files.

Fixed

• Fixed override serialization to use toJson() instead of hand-built maps, ensuring all fields (e.g. modelId, stability, similarityBoost, maxTokens) are included.

0.5.0 - 2026-04-09 [YANKED]

Note: This version was never published to pub.dev because the version in pubspec.yaml and lib/version.dart was not updated before tagging.

Added

• Optional environment parameter for startSession() to specify the target environment (e.g. "staging"). Defaults to "production" server-side when not specified.

Fixed

• Fixed client tool result message format to match backend expectations (type, tool_call_id, result, is_error fields).

0.4.0 - 2026-03-10

Added

• onAgentToolRequest callback on ConversationCallbacks, fired whenever the agent initiates a tool call. Receives toolName and toolCallId as named parameters, enabling apps to display a loading/thinking indicator during tool execution.
• AgentToolRequest event model with fields toolName, toolCallId, toolType, and parameters.
• Handling for the agent_tool_request protocol event (previously silently dropped). For tool_type: "client" the SDK now executes the registered ClientTool and returns the result automatically, matching the behaviour introduced in Android SDK v0.7.1.

0.3.1 - 2026-02-19

Changed

• Updated livekit_client dependency to ^2.6.0

0.3.0 - 2025-11-27

Changed

• Enhanced disconnect reason tracking in onDisconnect callback. The callback now receives specific disconnect reasons: "agent" (when agent disconnects), "user" (when user ends session), or "error" (for network/connection errors).
• Added disconnectStream to LiveKitManager for better disconnect event handling with reason tracking.

0.2.0 - 2025-11-20

Changed

• Relaxed Dart version requirements for the SDK. Now supports Dart versions 3 and up instead of being pinned to 3.9.2.
