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.

Full Changelog: https://github.com/parca-dev/parca/compare/v0.16.0...v0.16.1

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!
