What's the difference between D&D 4e and 5e?

Excuse me, I'm a bit confused about the differences between D&D 4e and 5e. Could you please elaborate on the main changes and updates in the latest edition? I'm particularly interested in the changes in gameplay mechanics, character creation, and the overall feel of the game. I'm a fan of the role-playing aspect and I'm wondering if 5e has enhanced this experience in any way. Additionally, are there any notable differences in the lore or setting of the two editions?
