@JeremyECrawford During the playtest, casters didn't have to prepare all their spells at once. Why did that change?

In the playtest, being able to prepare spells throughout the day made prep. spellcasters too adaptable: the right tool for every job! #DnD https://t.co/cMuPC6skwd

@pukunui81Fair enough. But it also makes it so if you go up a level during the day, you can’t prep any new spells till the next day. That's correct.
