[0.18.1] - 2026-04-10

Fixed

• (#588): Fix thread pool causing excessive CPU usage and slowdown when using multiple benchmark groups. Thread pools were not being properly shut down leaving worker threads stuck in hot loops.

[0.18.0] - 2026-04-09

Added

• (#565): --parallel CLI option and environment variable GUNGRAUN_PARALLEL to run benchmarks in parallel. max_parallel parameter in library_benchmark_group! and binary_benchmark_group! to be able to limit parallelism by benchmark group.
• (#575): Support const generic parameters in benchmark functions
• (#583): Support a custom valgrind runner with command-line arguments:
  • --valgrind-runner (env: GUNGRAUN_VALGRIND_RUNNER) option to run Valgrind through a container or alternative execution environment.
  • --valgrind-runner-args (env: GUNGRAUN_VALGRIND_RUNNER_ARGS) to pass additional arguments to the custom runner with support for environment variable interpolation using ${VAR} syntax.
  • --valgrind-bin (env: GUNGRAUN_VALGRIND_BIN) to specify a Valgrind executable path.
  • --valgrind-runner-dest (env: GUNGRAUN_VALGRIND_RUNNER_DEST) to override the destination directory for Valgrind output files.
  • --valgrind-runner-root (env: GUNGRAUN_VALGRIND_RUNNER_ROOT) to override the workspace root directory path.
  • Expose environment variables GUNGRAUN_VR_DEST_DIR, GUNGRAUN_VR_HOME, GUNGRAUN_VR_WORKSPACE_ROOT, GUNGRAUN_ALLOW_ASLR for custom valgrind runners.
• (#583): Customize environment variables on the command-line with:
  • --env-clear (env: GUNGRAUN_ENV_CLEAR) CLI argument to control environment variable clearing behavior for benchmarks.
  • --envs CLI argument to pass environment variables to benchmarks from the command line (supports both passthrough --envs=VAR and explicit --envs=VAR=value).
• (#585): gungraun::prelude module for convenient importing of commonly used items: library_benchmark, library_benchmark_group, binary_benchmark, binary_benchmark_group, main!, LibraryBenchmarkConfig, BinaryBenchmarkConfig, and Command.

Changed

• (#565): Improved performance
