latitude-dev/latitude-llm typescript-telemetry-3.0.0-alpha.1 on GitHub

Complete SDK re-architecture — monolithic Telemetry class replaced with modular, composable API
New bootstrap API — initLatitude() replaces new Telemetry() as primary entry point
capture() no longer creates spans — now only attaches context to spans created by auto-instrumentation
Context propagation changed — uses OpenTelemetry's native Context API instead of baggage
Removed manual instrumentation (telemetry.tracer still available via advanced setup)
Removed Telemetry class and TelemetryOptions interface
Removed Instrumentors enum — now use string literals via registerLatitudeInstrumentations()

initLatitude() — one-call bootstrap for complete OTel + LLM instrumentation setup
LatitudeSpanProcessor — composable span processor for shared-provider setups
registerLatitudeInstrumentations() — register LLM auto-instrumentations (OpenAI, Anthropic, etc.)
Smart span filtering — only LLM-relevant spans exported by default (gen_ai., llm., openinference., ai. attributes)
disableSmartFilter option — export all spans instead of just LLM spans
shouldExportSpan callback — custom span filtering
blockedInstrumentationScopes option — filter out unwanted instrumentation scopes
capture() now supports nested calls with proper context merging (tags dedupe, metadata shallow merge, last-write-wins for userId/sessionId)
Integration examples for Datadog and Sentry

SDK is now OpenTelemetry-first — designed for composability with existing OTel setups
capture() uses OTel's context.with() for reliable async context propagation
Span processors use standard OTel APIs (no deprecated methods)
Package structure: SDK split into sdk/init.ts, sdk/context.ts, sdk/processor.ts, sdk/span-filter.ts, sdk/types.ts
