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!
