[1.1.1] - 2026-01-07

🚀 Updates

  • Runtime Image Update: Updated to ghcr.io/opentechil/offline-python-runtime-docker:v1.1.0-release.0
  • Documentation Enhancement: Added clear guidance on offline package management process
  • Repository Links: Added direct links to runtime image repository for package requests

📦 Package Management

  • Offline Package Process: Documented process for adding packages to offline environments via runtime image
  • Repository Integration: Enhanced documentation linking to runtime image repository

[1.1.0] - 2026-01-07

🚀 Major Changes

  • Runtime Image Integration: Now uses ghcr.io/opentechil/offline-python-runtime-docker:v1.0.0-release.0 as base image
  • Runtime Package Management: Wheelhouse and package management moved to runtime for better compatibility

✨ New Features

  • Oracle Driver Support: Leverages Oracle Instant Client from runtime image
  • Runtime Wheelhouse: Package installation handled at runtime through pre-configured wheelhouse system
  • Simplified Architecture: Removed local requirements.txt dependencies, now managed by runtime image

🔄 Changes

  • Package Management: Core packages (pandas, oracledb, cryptography, etc.) now provided by runtime image
  • Build Process: Streamlined build process leveraging runtime image foundation
  • Compatibility: Enhanced offline compatibility through runtime wheelhouse system
  • Runtime Repository: Integration with offline-python-runtime-docker repository

📦 Package Updates

  • Core Python packages now sourced from runtime image
  • Oracle Instant Client 19.29 included via runtime image
  • Data science stack (pandas, numpy, scikit-learn) available from runtime

🏗️ Architecture

  • Multi-stage build: Runtime image as foundation with devcontainer customization
  • Optimized layers: Better Docker layer caching and reduced build times
  • Runtime flexibility: Package installation available both at build time and runtime

📚 Documentation

  • Updated README.md to reflect runtime image usage
  • Added runtime architecture explanations
  • Updated configuration examples for runtime package management

[1.0.x] - Previous Versions

🐛 Known Issues

  • Package management complexity with local wheelhouse
  • Build image size optimization needed
  • Oracle driver compatibility issues in some environments

Migration Guide

From v1.0.x to v1.1.0

Breaking Changes:

  • Local requirements.txt packages are no longer built into the image
  • Package management now happens at runtime

Recommended Actions:

  1. Update your development workflow to install packages at runtime:

    # Inside devcontainer
pip install your-package

  2. For persistent packages, create project-specific requirements.txt and install when container starts

  3. Update build scripts to use the new runtime image base

Benefits:

  • Faster build times
  • Better package compatibility
  • Simplified maintenance
  • Access to runtime wheelhouse with pre-compiled packages
