What's Changed

• feat: replace Linux FFI with pure Dart cgroup implementation by @thiagoalmeidasa in #15

Full Changelog: v2.1.2...v2.2.0

Pure Dart on Linux

• Hybrid architecture: Linux now uses pure Dart (reading /proc and cgroup filesystems directly), eliminating the need for native .so binaries. macOS continues to use FFI with native .dylib binaries.
• Removed Linux native binaries: libsysres-linux-*.so files are no longer shipped, reducing package size and improving compatibility across Linux architectures.

Cgroup v1 Support

• Cgroup v1 (legacy hierarchy): CPU and memory monitoring now works on systems using cgroup v1 in addition to cgroup v2.

New APIs

• cgroupVersion() - Returns detected cgroup version (v1, v2, or none)
• cpuLoad() - CPU load as a fraction of the cgroup limit (delta-based)
• cpuUsageMillicores() - CPU usage in millicores (delta-based)
• cpuUsageMicros() - Raw cumulative CPU usage in microseconds
• cpuLimitMillicores() - CPU limit in millicores
• clearState() - Clears all cached platform/CPU state (useful for testing)
• New exported enums: CgroupVersion, DetectedPlatform

Bug Fixes

• Resolve process's actual cgroup path for memory metrics on native Linux hosts
• Unify CPU load normalization to respect SYSRES_CPU_CORES environment variable
• Use DynamicLibrary.open directly instead of File.existsSync for better compatibility
• Improve native library compatibility with older glibc versions

What's Changed

• chore: pin GitHub Actions to commit SHAs by @thiagoalmeidasa in #9
• fix: rename docs/ to doc/ for Dart package conventions by @thiagoalmeidasa in #10

Full Changelog: v2.1.0...v2.1.1

• Fix package directory structure to follow Dart conventions (rename docs/ to doc/)
