+    All internally rebuilt `x86_64` dependencies now uniformly target the documented macOS 11.0 minimal ABI.
+    Previously, some still targeted macOS 10.12 or 10.13, even though support for 10.x was dropped in Agent 7.62.0 and
+    numerous `x86_64` dependencies were already targeting newer ABI versions.
