v1.0.9 - mTLS, OAuth Quick Wins, Tool Preview, Catalog Actions, and Security Hardening

[1.0.9] - 2026-08-31 - mTLS, OAuth Quick Wins, Tool Preview, Catalog Actions, and Security Hardening

Overview

Release 1.0.9 consolidates 41 PRs focused on inbound mTLS client certificate auth, MCP server OAuth improvements, pluggable OAuth token storage, tool preview and schema publishing, catalog gateway actions, TLS/SSL enhancements, and security hardening:

• Security & Auth - Inbound mTLS (client certificate authentication), pluggable OAuth token storage with HashiCorp Vault backend, MCP server OAuth form quick wins (read-only redirect URI, drop password grant), session refresh and validate endpoints, default token creation to creator's personal team, invisible Unicode stripping from stored auth credentials, and catalog registration scope enforcement.
• API & Platform - MCP handshake test endpoint for Test Connection and virtual servers, new tool preview permission and preview functions, tool schema publishing to dataplane, catalog gateway actions backend support, gateway-side TLS override for end-to-end HTTPS, versioned API aliases, recent activity feed endpoint, and durable observability metrics endpoints.
• Operations - Experimental UI added to compose, SSL/TLS exposed for gateway pods, TLS cipher suite exposure, automated catalog icon generation, and load test consolidation.
• Documentation - Dynamic env production risk documentation for translate, live black-box test requirement policy.
