Release Notes — v1.1.2

Released: 2026-05-21 Type: Patch — Stability & Integration Fixes

Summary

v1.1.2 is a quality-of-life and stability patch releasing critical fixes for exceptions handling, reporting tools, and RAM/CPU auto-detection routines. It also introduces one breaking change renaming the Django middleware for naming consistency.

Breaking Changes

Django Middleware Renaming

For naming consistency across integrations, the Django middleware class has been renamed to EcoTraceDjangoMiddleware and its module location updated to ecotrace.middleware.django. The FastAPI EcoTraceMiddleware remains unchanged.

# Old (v1.1.0)
MIDDLEWARE = [
    "ecotrace.middleware.django.EcoTraceMiddleware",
    ...
]

# New (v1.1.2)
MIDDLEWARE = [
    "ecotrace.middleware.django.EcoTraceDjangoMiddleware",
    ...
]

Bug Fixes & Engine Improvements

1. Robust Exception Propagation

In measure and measure_async decorators/managers, user exceptions are now guaranteed to propagate after measurement teardown. Any internal EcoTrace telemetry errors during teardown are caught and handled, preventing them from masking original application failures.

2. Session atexit Optimization

Replaced per-instance registration of atexit handlers with a class-level handler tracking active WeakSet instances, reducing clean-up overhead and preventing memory retention issues during runtime restarts.

3. RAM & CPU Hardware Detection

  • Windows: Upgraded to use PowerShell Get-CimInstance to retrieve RAM info, deprecating wmic usage which could trigger security or deprecation warnings on newer Windows editions.
  • Linux: dmidecode is run without sudo first. If output is empty, it attempts sudo -n for passwordless execution.
  • CPU Info Caching: The caching logic was improved to reuse fetch_raw_cpu_info() results instead of performing redundant cpuinfo calls.

4. PDF & CSV Reporting

  • generate_pdf_report now accepts custom log_path.
  • CSV report parser now correctly resolves columns via DictReader column names instead of hardcoded indexes, improving durability against log schema modifications.

5. Dependency & Versioning Tweaks

  • Gemini AI: google.generativeai package is now lazy-loaded inside get_gemini_insights(), avoiding unnecessary startup delays when AI features are not used.
  • User Agent: Resolved from installed package version with appropriate fallback values.
  • Update Checker: Added safety check to return False if parsing version strings fails.
  • Restored the default log level to WARNING to reduce terminal noise.
