What changed in v2.10.1 — 2026-08-22

One fix, reported the day 2.10.0 landed: the new enum argument was unusable in the shape an SDK actually writes.

Fixed

• An attribute's field default holds in every module that uses the attribute. A default is written where the attribute is DECLARED — layout: Layout = Layout.Shared in the SDK — and read wherever someone writes @Saved. What a name in it MEANS is settled when its own declaration is checked, and declarations were checked in discovery order, so a use could be checked before the declaration it depends on. The result:

  in another module
  @Saved { layout = save.Layout.Separate }	compiled
  @Saved	LYR-SEM0069
  @Saved { version = 2 }	LYR-SEM0069

  The same code in a single file compiled, which is the tell. Declarations are checked in dependency order now — every module after the ones it imports — the same order globals have taken since 2.8, and for the same reason.

  It applies to both forms a default can name: an enum variant (2.10) and a let bound to a value (2.4).
