BREAKING

• Add alloca-based memory layout randomisation to mitigate memory effects on measurements.
• Add doc comment to benchmark runner in criterion_group macro (removes linter warnings)

Fixed

• Fix plotting NaN bug

Other

v0.7.0

Compare Source

• Bump version of criterion-plot to align dependencies.

v0.6.0

Compare Source

Changed

• MSRV bumped to 1.80
• The real_blackbox feature no longer has any impact. Criterion always uses std::hint::black_box() now.
  Users of criterion::black_box() should switch to std::hint::black_box().
• clap dependency unpinned.

Fixed

• gnuplot version is now correctly detected when using certain Windows binaries/configurations that used to fail

Added

• Async benchmarking with Tokio may be done via a tokio::runtime::Handle, not only a tokio::runtime::Runtime
