Mage Armor 5e 2024 vs. 2014 edition differences

Both versions have the same duration, classes, and effect. The 2024 version explicitly states the spell ends early if the target dons armor, whereas the 2014 version states it ends if the target dons armor or if you dismiss it as an action. No significant mechanical differences.
