Release Notes

0.104.0 (2026-09-27)

⚠ BREAKING CHANGES

• grammar: Fixes the precedence of ! and the associativity of
  the ? : conditional when parsing return type expressions from
  extension YAMLs. This can be breaking for user defined extension YAMLs
  which may have relied on ! binding looser than AND and OR, or on a
  chained ? : grouping to the left; both now follow conventional
  precedence and associativity.

Features

• add support for window function testing (#1209) (d149822)

Bug Fixes

• grammar: bind ! tighter than AND/OR and right-associate ? : (#1228) (0f9b92b)
• site: track generated documentation inputs (#1194) (930f109), closes #1144
• tests: remove byte-identical duplicate test case lines (#1239) (5c6046b)
• tests: validate row shape matches column count in tables (#1235) (b0341ce)
