🚀 LogTide v0.8.0: Frontend Observability & MongoDB Support

This release is a massive milestone for LogTide, frontend observability, a brand new MongoDB storage engine, and a completely overhauled metrics experience with lightning-fast rollups.

🌐 Browser & Frontend Observability

Monitor your frontend applications with the same precision as your backend.

• New @logtide/browser SDK: Dedicated SDK with session tracking, Core Web Vitals (LCP, INP, CLS), and offline resilience.
• Rich Breadcrumbs: Automatic tracking of clicks (with data-testid support) and network requests (Fetch/XHR) with built-in PII stripping.
• Source Maps Support: Use the new logtide sourcemaps upload command in the CLI to see original source code in stack frames instead of minified junk.
• Framework First: Specialized support for Next.js (RSC errors), Nuxt (Pinia), SvelteKit, and Angular.

📊 Metrics Dashboard & Smart Rollups

The metrics experience has been redesigned for speed and depth.

• New Metrics Dashboard: Features an Overview tab with ECharts sparklines and an Explorer tab for granular analysis.
• Pre-aggregated Rollups: TimescaleDB and ClickHouse now use continuous aggregates and materialized views to make dashboard queries instant even on billions of data points.
• Golden Signals: Monitor P50/P95/P99 latency, error rates, and throughput percentiles across all storage engines.

🍃 MongoDB Storage Engine

LogTide is now even more flexible. The @logtide/reservoir package officially supports MongoDB 7.0+ as a storage backend.

• Full implementation for logs, spans, traces, and metrics.
• Support for MongoDB time-series collections and native aggregation pipelines.
• Ideal for teams preferring a document-based stack over SQL or ClickHouse.

✨ Other Enhancements

• Smart Project Selectors: Dropdowns now intelligently filter to show only projects that have data for the specific category (Logs, Traces, or Metrics).
• DSN Copy: Quickly copy the DSN connection string directly from the API Key creation dialog.
• Custom Time Ranges: Improved support for custom ranges synced with URL parameters for easy sharing.
