v0.3.1

v0.3.1

"If it happened, emit it."

Events improvement release — richer stream lifecycle, tool call visibility, and several bug fixes.

Deprecations

• EventNew* aliases (EventNewToken, EventNewToolCall, etc.) — use EventToken, EventToolCall (#49) (removed in v0.4.0)
• StreamEvent.GetType — unexported, interface is now sealed (#49)

Bug Fixes

• Goroutine leak in ApproveWaiter.Resolve on context cancellation — resolveSync now selects on ctx.Done() (#48)
• EventToolCall double resolution when copied — answered field replaced with shared *atomic.Bool (#52)
• Resolve() on an already-resolved tool call silently did nothing — now returns ErrAlreadyResolved (#52, #45)

Features

• New stream events: EventCompletionStarted, EventToolCallToken, EventToolCallResolved (#50, #41)
• Tool execution results emitted to event stream as EventToolMessage (#50, #46)
• EventCompletionEnded.ToolCalls — collects all tool calls from the current generation (#50, #47)
• JSON serialization for stream events via MarshalEvent / UnmarshalEvent (#49, #39)
• Configurable Chat.DeclinedToolMessage field, default: "Tool call declined" (#52, #42)

Changes

• Event types renamed for idiomatic Go style: EventNew* → Event* (#49, #40)
• eventType switched from uint/iota to string constants (#49)

v0.3.0

"The zero value is useful."

Minor release — contains one breaking API change.

Bug Fixes

• Chat{} without Tools field panicked on first Session() call — ensureDefaults() now initializes nil Messages and Tools lazily (#31)

Breaking Changes

• NewTools() now returns *Tools instead of Tools — callers that stored the result in a variable and passed &toolList must drop the & (#32)

Other

• Examples and documentation updated to reflect new constructor signatures (#34)

v0.2.2

v0.2.2

"Minor version numbers are for when you're ashamed of the changes."

Patch release — no breaking API changes.

Bug Fixes

• Models losing memory — Session was appending assistant responses as EventNewToken instead of EventNewAssistantMessage; since SyncInput is not required to sync streaming-only events, assistant turns were silently dropped from context on every subsequent request (#26)

v0.2.1

v0.2.1

Patch release — no breaking API changes.

Bug Fixes

• Partial tool call assembly — providers that stream tool call arguments in chunks no longer deliver broken JSON to callers; Session now assembles fragments into complete events before forwarding (#22)
• Primitive tool input unmarshaling — NewTool now correctly handles primitive input types (string, int, bool, float64) via reflection; previously only structs worked reliably (#21)
• Empty OpenAI streaming chunks — empty choices in OpenAI streaming responses no longer cause parse errors (#18)

Improvements

• Stream.Next() now respects context cancellation
• Session internals refactored into sessionState struct for maintainability
• Tool call events are dispatched as soon as fully assembled, not batched at end of generation
