v0.37.0

0.37.0 (2026-10-18)

⚠ BREAKING CHANGES

• following spec v0.105.0, avg over a decimal derives a
  nullable DECIMAL?<38,S> result. Following spec v0.106.0, the date
  and precision_time round_calendar overloads no longer take a
  trailing origin argument; plans must use the signatures without it.
• project, select and aggregate grouping
  expressions now raise ValueError for an expression with two or more
  output names that do not match its output type, nested fields included,
  and for an expression with no output names; previously only the first
  name was kept. column() raises when an alias list has two or more
  names but not exactly one per field, and a single alias on a struct
  column now keeps its nested names (column("s", alias="z") gives ["z", "x", "y"] instead of ["z"]). Rename a column with a single alias, or
  pass a list that names every field in depth-first order.
• deps: return type derivation expressions now bind ! tighter
  than AND and OR and group chained ? : conditionals to the right,
  following spec v0.104.0. User-defined extension YAMLs that relied on the
  previous grouping derive different return types.
