3.3.3

Improved

• Spell-level chips on the level-up's Spells step. When a level-up gains more than one level,
  a row of chips shows how many of your new spells can be of each spell level, and how many you've
  used, such as Lvl 3 1/2. Click a chip to show only the spells that pick can take, its level
  and below, and click it again to show everything. It works alongside the search and the other
  filters. A level-up of one level shows a single chip.
• The magic shop's slot chips filter the shelf. Click a rarity slot to show the items it can
  take, that rarity and lower, and click it again to show everything. It works alongside the
  category and rarity filters.
• One spell swap for each level gained. Classes that replace one spell when they gain a level
  now replace one for each level a level-up gains, rather than one per level-up. A Sorcerer going
  from 9th to 12th level can replace three. Each replacement follows the same spell-level limit as
  a new spell.

Fixed

• Spells learned across several levels are limited to the level they're learned at. A level-up
  of several levels, including a Custom build above 1st level, asked for every new spell on one
  screen and allowed any spell up to the final level's highest slot. A 2014 Sorcerer built at 9th
  level could learn eight 5th-level spells, and a Wizard could write sixteen into its book. Each
  new spell is now limited to what the class could cast at the level it comes from, so that
  Sorcerer learns one 5th-level spell at most. This covers the Wizard's spellbook and the classes
  that change their spells only when they level up: the Bard, Sorcerer and Warlock, the 2014
  Ranger, the Eldritch Knight and the Arcane Trickster. Classes that change their spells after a
  long rest, such as the Cleric, Druid and 2024 Paladin, are limited only by their final level, as
  before, since they could have changed their list between levels anyway. Quick Build already
  levelled one level at a time and is unchanged.
