Heroism 5.5e 2024 vs. 5e 2014 edition differences

The 2024 version states "up to 1 minute" duration, but functionally same as 2014; both grant immunity to frightened/Frighened condition and temporary hit points equal to caster's spellcasting ability modifier at start of each turn. The 2024 version omits the clause about losing remaining temporary hit points when the spell ends.
