Release v0.18.0 · parca-dev/parca

This release comes packed with performance improvements, enhancements and so many fixes to the UI and CI!

Parca will now automatically use the system settings for light or dark themes.
gRPC Prometheus histograms are now exposed as native histograms giving them a much higher fidelity.
If running with a custom path prefix, all API endpoints will now be served under this prefix.

Happy profiling!
