The repeat picker got a full redesign, because "every week" is more complicated than it sounds.

Frequencies are now pills: Daily, Weekly, Monthly, Yearly, Custom. One click to switch. When you pick Weekly, you get a weekday grid you can click directly: tap Tue and Thu to say "every Tuesday and Thursday." No dropdowns, no counters, no wrestling with rule-builders.

It's the difference between "every 1 week with BYDAY=TU,TH" and "pick the days you mean." We picked the second one.
