IBM ContextForge MCP Gateway<=v1.0.7Upgrade to v1.0.8. See [release notes](https://github.com/IBM/mcp-context-forge/releases/tag/v1.0.8). Rotate `JWT_SECRET_KEY`, `AUTH_ENCRYPTION_SECRET`, `DATABASE_URL`, `REDIS_URL`, and `BASIC_AUTH_PASSWORD` on any deployment running prior versions.

  Note: From version v1.0.8 on a more complex AUTH_ENCRYPTION_SECRET is required:
Action required before upgrading: run the one-shot re-encryption script (mcpgateway/scripts/migrate_enc_secret.py) with the old and new keys while the gateway is stopped.
