What
The thinking configuration gains a field marking whether the display setting was chosen explicitly. When a non-interactive text or json session omits thinking implicitly, the field is set false so subagents and later session setup can re-derive the setting instead of treating it as a deliberate preference.
Details
The field does not exist in v2.1.245.
