Release Notes — v1.2.1

Released: 2026-06-03 Type: Patch Release — Bug Fixes & Security Updates

Summary

v1.2.1 is a quality-of-life and security patch release addressing compatibility bugs, API vulnerabilities, and alignment issues identified in the v1.2.0 release.

Changes & Fixes

1. Robust Windows RAM Detection

Replaced deprecated wmic with PowerShell Get-CimInstance for Windows RAM speed detection, resolving issues on Windows 11 24H2 where wmic has been removed. Added robust local exception handling for dmidecode on Linux to ensure fallback to sudo -n works seamlessly even if non-sudo execution raises environment errors.

2. Machine Learning Tracker Enhancements (EcoTraceML)

  • Constructor Parameters: Added missing project_name, epochs, batch_size, and dataset_size parameters to both EcoTraceML context manager and @ecotrace_ml decorator as documented in v1.2.0.
  • CSV Headers Alignment: Aligned the logging header and columns produced by EcoTraceML with the main EcoTrace core format, resolving parse errors during ecotrace analyze CLI and JSON export phases.

3. Security Hardening

  • Switched the user region check API from HTTP (http://ip-api.com) to HTTPS (https://ip-api.com) to prevent MITM tampering.
  • Made the USER_AGENT resolve dynamically based on the installed package version.
  • Updated supported releases in SECURITY.MD to include v1.2.x and v1.1.x.

4. Code & Lifecycle Improvements

  • Renamed the misleading WATTS_PER_KILOWATT variable to MILLIWATTS_PER_WATT in GPU NVML power scaling.
  • Implemented class-level atexit registration with WeakSet in EcoTrace to avoid duplicate session summaries when handling multiple concurrent tracking instances.
