 # Changelog
 
+## 0.1.2

+- Synced the integration skill from agent-skills commit `6685971`, retaining the plugin's MCP guidance.
+- Verified raw-body webhook signatures and confirmed onboarding redirects against the authenticated customer and project API.
+- Clarified Flow transport authentication, customer authorization, and unsigned synthetic preview behavior.
+- Required HTTPS by default, rejected authenticated redirects, and redacted recognized credentials while allowing private capture of one-time secrets.
+- Preserved ordinary Bearer text and shared credential redaction across nested JSON diagnostics.
+- Added offline integration regression tests to CI.
+- Matched the Codex manifest and marketplace entry to the existing public submission identifier and removed pricing copy from listing metadata.
+
 ## 0.1.1
 
 - Added Kapso Findings MCP guidance, evidence workflows, and approval rules for investigation and verification actions.
