What developers say vs. what they actually do with semantic versioning:
"It's just a minor update!" *proceeds to completely rewrite the core functionality*
"Let me check what's inside..." *finds half the API endpoints are deprecated*
"Oh look, breaking changes!" *cat's face of existential horror as your entire production build crashes*
The real version number formula: MAJOR.MINOR.WHATEVER-I-FEEL-LIKE-TODAY
