What's Changed

OpenTelemetry & LGTM

• chore(deps): update dependency opentelemetry-collector to v0.145.0 by @​renovate-sh-app[bot] in #​1019
• chore(deps): update dependency pyroscope to v1.18.1 by @​renovate-sh-app[bot] in #​1032

New: Zero-code observability with eBPF

The grafana/otel-lgtm image now bundles OBI (OpenTelemetry eBPF Instrumentation). OBI automatically generates traces and RED metrics for HTTP/gRPC services using Linux eBPF — no SDKs, no agents, no code changes.

ENABLE_OBI=true ./run-lgtm.sh

Target specific languages with OBI_TARGET=java|python|node|dotnet|ruby, or let OBI auto-discover services on common ports.

Requires Linux kernel 5.8+ and privileged Docker mode (handled automatically by run-lgtm.sh).

See the README for configuration details and the OBI example for a multi-language demo with 5 uninstrumented apps.
