📦 NEW: Python Release System

[arre-ankit]

TLDR

Implements automated release system for the Langbase Python SDK with version bumping, changelog generation, and PyPI publishing support

Dive Deeper

Impact: Developers can now release new SDK versions with a single command, reducing manual errors and improving release consistency

Key Changes:

🚀 New release.py script for automated version management
📝 Automated changelog generation and version bumping
🔧 Integration with PyPI publishing workflow
📚 Updated CONTRIBUTING.md with release instructions

🎯 Problem Statement

The SDK lacked a standardized release process, making it difficult to:

• Consistently bump version numbers across all files
• Maintain accurate changelog entries
• Ensure all release steps are followed correctly
• Reduce human error in the release process

💡 Solution Overview

• Created a comprehensive release system that automates the entire release workflow:
• Version Management: Automatically bumps version in init.py, pyproject.toml, and other relevant files
• Changelog Updates: Generates changelog entries based on conventional commits and PR patterns
• Git Integration: Creates release commits and tags automatically
• PyPI Ready: Prepares distribution packages for publishing

pyproject.toml:8

• The release rule mapping '📦 NEW' to 'major' releases seems inconsistent with semantic versioning conventions. New features typically warrant minor version bumps, not major ones. Major bumps should be reserved for breaking changes.

[nitpick] Setting environment variables globally in a script can have unintended side effects. Consider wrapping the script execution in a function that sets these temporarily or documenting why global setting is necessary.
