 This catalog-only hotfix pins the three RCC6 releases that make saved-location advertising explicit:
 
-- RCC6 Ultimate Companion `v2.3.0-rc.4`
-- RCC6 Headless Companion `v1.0.0-rc.2`
-- RCC6 Ultimate Observer and Room Server `v1.3.0-rc.2`
+- RCC6 Ultimate Companion `v2.3.0-rc.5`
+- RCC6 Headless Companion `v1.0.0-rc.3`
+- RCC6 Ultimate Observer and Room Server `v1.3.0-rc.3`
 
-Web location controls now show whether saved coordinates will be included in MeshCore adverts. Existing nodes are not silently opted in: the user must select the sharing policy.
+Web location controls show whether saved coordinates will be included in MeshCore adverts. The current safety refresh also rejects impossible RCC6 single-cell ADC readings, renders the unavailable state honestly, preserves chart time slots, and suppresses invalid battery telemetry.
 
 The RC52, Heltec V3/V4, and ULP families are unchanged because they do not expose this misleading RCC6 Web location flow.
