4.13.0 - 2026-03-26

Release Notes

In this release we've added support for comparing a local run with another run using --base <runId>.

4.12.1 - 2026-03-20

Release Notes

Fix a bug where memory profiling with codspeed exec for binaries that use statically-linked allocators (e.g. jemalloc in Rust). Previously, we reported incorrect memory usage because it didn't attach to the statically linked allocators.
