Pool

v1.2.0 - Pool

Release Notes: v1.1.0 → v1.2.0

This release introduces significant performance optimizations (including parallel process collection and native GPU engine monitoring), layout and input enhancements, supply chain signature verification, and a streamlined Windows-native CI pipeline running on Go 1.26.4.

🚀 Performance Improvements

• Parallel Process Collection: Consolidated and parallelized process metadata querying using a concurrent worker pool (16 workers). This yields a ~22% speedup at idle, reducing average cycle collection time from ~31.3ms to ~24.4ms.
• Native GPU Engine Queries: Replaced the expensive PowerShell-based subprocess querying (Get-Counter) with a native Go implementation using Windows DXGI (for VRAM capacities/utilization) and PDH counter APIs (for 3D engine utilization). This reduces non-NVIDIA GPU query time from several seconds down to < 1ms, eliminating CPU spikes during collection.

🎨 User Experience & UI Enhancements

• Responsive Top Panel Layout: Added a dynamic 3-column top panel (Memory | GPU | Network) that automatically displays on terminals wider than 110 characters. On narrower screens, it gracefully falls back to a 2-column layout (Memory | GPU) to preserve space.
• Full Table Mouse & Navigation Support: Forwarded all terminal events to bubbles/table, enabling native mouse selection (click-to-focus), scroll-wheel list scrolling, and standard page key navigation (PageUp, PageDown, Home, End).
• StatusBar Wrap Prevention: Implemented rune-safe truncation for status bar elements (hostname, version, and legends) to prevent ugly wrapping on narrow screen widths.
• Scroll Selection Fix: Resolved alignment offsets in the selection highlights when scrolling long lists.

🔒 Supply Chain Security & Verification

• SBOM Signing & Attestation: Added a CycloneDX Software Bill of Materials (SBOM) generation step in the release workflow. The SBOM is attested and signed using keyless Cosign (via GitHub OIDC).
• Cryptographic Verification Script: Introduced the Verify-Release.ps1 PowerShell script, allowing users to verify the cryptographic signatures, SHA256 hashes, and OIDC attestations of downloaded binaries and SBOMs.
• WinGet Manifest Verification: Added a -WinGet validation flag to Verify-Release.ps1 to automatically inspect and verify WinGet manifests against GitHub releases.

🛠️ CI/CD & Pipeline Tooling

• Native Windows CI runner: Migrated the Build, Vet, Lint, and Test workflows from a Linux runner to execute natively on windows-latest. This ensures all Windows-specific code paths (DXGI/PDH) are compiled, linted, and tested under the expected OS target.
• Winget now automatically updates on release publish.
• Go 1.26.4 Toolchain Support: Configured the runner to use Go 1.26.4. To support this version, golangci-lint is now compiled from source on-the-fly inside the runner using Go 1.26.4.
• Normalized Line Endings: Added a .gitattributes configuration (*.go text eol=lf) to enforce LF line endings, preventing gofmt carriage return formatting failures on Windows runners and environments.
