What's Changed

We now collect buildtime and runtime environment data to warn users about differences in their runtime environment when comparing two runs against one another.

This data includes toolchain metadata like version and build options, as well as a list of dynamically loaded linked libraries.

• feat(codspeed): collect Rust toolchain environment at build time by @​GuillaumeLagrange in #​171
• Bump instrument hooks and collect linked libraries by @​GuillaumeLagrange in #​173

Full Changelog: CodSpeedHQ/codspeed-rust@v4.4.1...v4.5.0
