Version 0.8.6 (October 29, 2025)

Phase 1: Core Version Automation - COMPLETE 🎉

This release implements a comprehensive automatic versioning system that updates the version after every commit with no manual intervention required.

Version Management Enhancements

✅ Enhanced Version Module (__version__.py):

  • Added Version Tuple: Introduced __version_info__ tuple for programmatic version comparisons

  • Dual Format Support: Maintains both string ("0.8.6") and tuple ((0, 8, 6)) formats

  • PEP 396 Compliance: Follows Python best practices for version attributes

  • Benefit: Enables version comparisons like if __version_info__ >= (1, 0, 0)

🔧 Enhanced Version Bumping (.git/hooks/bump-version):

  • Dual Update System: Automatically maintains both __version__ string and __version_info__ tuple

  • Python Import Validation: Tests version import after each update to catch errors immediately

  • Tuple Consistency Check: Validates that tuple matches the string version

  • Centralized Logging: Records all version bumps to .logs/version_updates.log with timestamps

  • Cross-Platform Support: Works seamlessly on macOS and Linux

  • Conventional Commits: Auto-detects bump type from commit messages: * feat: → Minor bump (0.8.5 → 0.9.0) * fix: → Patch bump (0.8.5 → 0.8.6) * feat!: or BREAKING CHANGE: → Major bump (0.8.5 → 1.0.0)

  • Benefit: Robust, automatic version updates with complete audit trail

📝 Centralized Logging (scripts/utils/check_documentation_quality.py):

  • Log Location Fix: Moved log file from docs/sphinx/ to .logs/ directory

  • Auto-Directory Creation: Creates .logs/ directory if it doesn’t exist

  • Consistent Location: All project logs now in centralized .logs/ folder

  • Benefit: Cleaner project structure and easier log management

Migration Notes

From Pre-1.0 Versions

If upgrading from development versions:

  1. Update imports:

    # Old
from extract_data import process_excel_file

# New
from scripts.extract_data import process_excel_file

  2. Check configuration:

    config.py now uses dynamic dataset detection. Ensure your data structure follows:

    data/dataset/<dataset_name>/

  3. Update paths:

    Results now organized as results/dataset/<dataset_name>/
