v1.8.3

• GH-1645: Fix &size check.

  The current parsing offset could legitimately end up just beyond the &size amount.

• GH-1617: Fix handling of %synchronize-* attributes for units in lists.

  We previously would not detect %synchronize-at or %synchronize-from attributes if the unit was not directly in a field, i.e., we mishandled the common case of synchronizing on a unit in a list.

  With this patch we now handle these attributes, regardless of how the unit appears.
