Major improvements to release note generation system:
**AI Model Optimization:**
- Switch from Claude Sonnet 4.5 to Haiku 4.5 (67% cheaper, 50% faster)
- Cost reduced from 1.0 to 0.33 Premium requests per generation
- Generation time reduced from ~30s to ~15s
- Quality maintained through improved prompt engineering
**Improved Prompt Structure:**
- Restructured prompt: instructions first, commit data last
- Added explicit user-feature prioritization rules (sensors > config > developer tools)
- Integrated file change statistics with each commit
- Added file path guidance (custom_components/ = HIGH, scripts/ = LOW)
- Added 3-step decision process with walkthrough example
- Added explicit output constraints to prevent meta-commentary
**Auto-Update Feature:**
- Consolidated improve-release-notes functionality into generate-release-notes
- Automatic detection of existing GitHub releases
- Interactive prompt to update both title and body
- Shows comparison: current title vs. new AI-generated title
**File Statistics Integration:**
- Added --stat --compact-summary to git log
- Shows which files changed in each commit with line counts
- Helps AI quantitatively assess change importance (100+ lines = significant)
- Enables better prioritization of user-facing features
**Testing Results:**
- Generated title: "Price Volatility Analysis & Configuration" (user-focused!)
- Successfully prioritizes user features over developer/CI changes
- No more generic "New Features & Bug Fixes" titles
- Thematic titles that capture main release highlights
Impact: Release note generation is now faster, cheaper, and produces
higher-quality user-focused titles. Single consolidated script handles
both generation and updating existing releases.
Added mandatory validation steps to release workflow:
- Job 1: validate (hassfest + HACS) - runs before release
- Job 2: lint (Ruff check + format) - runs before release
- Job 3: sync-manifest - only runs if validation passes
- Job 4: release-notes - only runs if all previous jobs pass
This ensures no release is created if code doesn't pass validation.
Fixed generate-release-notes script to suppress colored output in CI:
- Added log_info() wrapper that sends output to stderr in CI
- Keeps release notes clean (only markdown, no ANSI codes)
- Local execution still shows colored output for better UX
Impact: Release workflow now fails fast if validation fails. Release
notes are clean without shell output artifacts.
