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.
I really like X.Y.Z
