I really like X.Y.Z
X is for major overhauls. Y is for a new individual feature added or dramatically reworked, Z is for bug fixes, updates and polish.
Like Blender is currently on 3.6. They had a dramatic major program wide overhaul a few years ago. And since then have been adding new features and reworking old ones in major 3.X releases, and occasionally have smaller updates and fixes in between, giving us 3.X.Y updates.
And it’s not even a good search engine either. It just spits out sarcastic jokes from barely up voted reddit posts.
