Version 1.3 release notes

We are excited to present Grafana Pyroscope 1.3.

This release focuses on improving stability and interoperability to make Pyroscope more reliable and easier to use.

Several major improvements were made to the compaction process:

  • Improved performance and storage efficiency of the symbol compaction process.
  • Optimized data processing by adding support for time-based down-sampling during the compaction process.
  • Added tracing integration to compaction for better observability.
  • Improved system stability during compaction shutdown
  • Added a profilecli compact command

Notable changes are listed below. For more details, check out the Full 1.3.0 Changelog: https://github.com/grafana/pyroscope/compare/v1.2.1...v1.3.0
