v0.21.0

2 months ago

What's Changed

Highlights

The UI has seen many improvements in this release, including a redesign of the time range picker, a new feature to highlight similar stacks when hovering on a node, and the replacement of loading spinners with skeleton placeholders. Now, the UI also displays CPU cores per second for sample count profiles to make them comparable with different underlying profiling durations.

v0.18.0

11 months ago

We're happy to release Parca v0.18.0!

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!

v0.16.0

1 year ago

This release is a major milestone for the Parca project. We have removed the Merge button, as we are now comfortable with the performance of these queries being run by default when querying data. We now felt comfortable after months of work improving the performance of the storage.

Many many more awesome changes, below is a more exhaustive changelog.

Happy profiling!
