Versioning Standard

Package Concept (2)

PEAR Coding Standard

• Why Standardize?

• Common Perception of What X.Y Means
• Tools Need to Compare Versions

• major [.minor [.patch]] [pre]

• "major" version: numeric, 0 means "experimental"
• "minor" version: new features ok, BC maintained
• "patch" version: bug fixes, tiny changes
• "pre" element: {dev,a,b,RC,pl}//N//

• Comparing:

• version_compare() function (from PHP 4.1.0)
• 0.x < 1.x < 2.x ...
• 0.1 < 0.9 < 0.10 < 1.0 ...
• 1.0dev1 < 1.0a1 < 1.0b1 < 1.0RC1 < 1.0 < 1.0pl1
