+constraint, a changed default. A raised floor is **not** breaking: code keeps
+compiling, older SDKs simply stop resolving the new version.

 Prefer **one short bullet** per entry, describing the functional change. Longer
 entries are acceptable for user-visible multi-facet features where the extra
 context matters to someone deciding whether to upgrade — but avoid sub-bullets,
