Version Pinning
Domain: Software Engineering
🎯 Motivation
Specifying exact versions of dependencies to prevent unexpected breaks.
📋 Concrete Example
Pin: ‘requests==2.31.0’ (exactly this version). If requests releases 2.32 with breaking changes, your code is safe. You upgrade deliberately, not accidentally.
🔗 Analogy
Version pinning is like locking in a flight price - you pay exactly the price you saw. If prices go up, you are not affected. Pinning locks dependency versions to prevent unexpected breaks.
