4.2.0 - 2025-10-16

Changes

✨ This new release adds a way for the runner to save and restore instruments it installs to a cache directory. The CodSpeed github action automatically makes use of these feature to speedup runs in your CI!

Details

🚀 Features

• Allow caching installed executor instruments on ubuntu/debian by @GuillaumeLagrange in #129
• Automatically compress archive if profile folder is above a certain threshold by @GuillaumeLagrange in #130

🐛 Bug Fixes

• Bump git2 to latest to support sparse checkout by @adriencaccia in #131

⚙️ Internals

• Make fifo command dump trace level by @GuillaumeLagrange in #130

4.0.0 - 2025-09-01

Release Notes

💥 BREAKING

It's now required to explicitly set the runner mode to instrumentation or walltime using either:

• the --mode CLI argument
• or the CODSPEED_RUNNER_MODE environment variable

Tip

Before, this variable was automatically set to instrumentation on every runner except for CodSpeed macro runners where it was set to walltime by default.

Details

🚀 Features

• Make perf profiling enabled by default by @GuillaumeLagrange in #110
• Make the runner mode argument required by @GuillaumeLagrange
• Use introspected node in walltime mode by @GuillaumeLagrange in #108
• Add instrumented go shell script by @not-matthias in #102

🐛 Bug Fixes

• Compute proper load bias by @not-matthias in #107
• Increase timeout for first perf ping by @GuillaumeLagrange
• Prevent running with valgrind by @not-matthias in #106

🏗️ Refactor
