[dependabot]

Release notes

Sourced from gungraun's releases.

v0.19.0

[0.19.0] - 2026-05-15

Changed

• (#607, #610): Bumped the MSRV from Rust 1.74.1 to 1.85.1. Bumped the workspace edition from Rust 2021 to Rust 2024.
• (#607, #608, and others): Updated dependencies, including migrating internal benchmark configuration encoding from bincode to bincode-next.
• (#609, #628): Replaced the thread-pool busy loop with a condition-variable based wakeup mechanism to avoid CPU usage while worker threads are idle.
• (#627): Set Valgrind --vgdb=no by default because it can cause problems in qemu-based runs.
• Bumped gungraun-macros from 0.8.0 to 0.9.0.

Fixed

• (#625): Fixed --valgrind-args from the CLI or env GUNGRAUN_VALGRIND_ARGS not being added to the final Valgrind argument list.

[0.18.2] - 2026-04-30

Fixed

• Small documentation fixes in the libraries and guide across multiple prs: Typos, capitalization, wrong indentation in code blocks, ...

[0.18.1] - 2026-04-10

Fixed
