v2.2.0

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.

• ci: stop targeting our fork for BCR PR by @GuillaumeLagrange in #43
• Implement toolchain harvesting for cpp by @GuillaumeLagrange in #46
• chore: bump instrument-hooks to collect runtime libraries by @GuillaumeLagrange in #47
