Additional info on Semantic Versioning

Описание: Summary
This discussion between Joe Glines and Isaias Baez focuses on semantic versioning in software development, particularly its implementation in AutoHotkey. They explore how version numbers are structured, their meanings, and the significance of different versioning components including metadata handling.

Key Points

[00:00:00] - Introduction to Semantic Versioning
• Different programs track changes through version numbers
• Traditional versioning systems used four digits (e.g., 1.1.37.7)
• Modern semantic versioning typically uses three digits (e.g., 1.0.0)

[00:01:36] - Core Components of Semantic Versioning
• Major version: Breaking changes that affect compatibility
• Minor version: New features that maintain compatibility
• Patch version: Bug fixes and small updates
• Example: AutoHotkey 2.0.19 indicates 19 fixes since version 2.0

[00:03:02] - Version Comparison and Breaking Changes
• Major changes (first number) indicate incompatibility with previous versions
• Minor changes (second number) represent new features
• Patch changes (third number) represent fixes
• Version comparison helps developers track compatibility

[00:06:00] - Metadata and Pre-release Versions
• Use of dash (-) for pre-release versions (e.g., alpha, beta)
• Plus sign (+) for build metadata
• Metadata after plus sign doesn't affect version comparison
• Example: Alpha-1 vs Beta-1 comparison mechanics

[00:11:55] - Advanced Version Handling
• Build metadata doesn't affect version comparison
• Same version with different metadata is treated as identical
• Useful for tracking builds while maintaining version consistency
• Important for developer tooling and version management

Brief Summary
The discussion provides a comprehensive overview of semantic versioning, emphasizing its importance in modern software development. The speakers highlight how this standardized approach helps developers manage versions, track changes, and maintain compatibility while providing clear information about the nature of updates through the version number structure.
