+## 🚀
+

+- Added Claude Opus 4.5 model support across Anthropic and Vertex AI providers.
+- Introduced database token authentication support for OpenOps Tables, enabling secure token-based access from workflows and applications.
+

+- Fixed workflow pagination so the first page is always filled before showing later pages.
+- Corrected Axios error log formatting to make errors easier to read and diagnose.
+- Fixed AI assistant error boundaries and conversation error handling to prevent crashes and failed chats.

+
+## ✨
+
+- Refined step name generation to use alphabetical indexing, improving workflow readability.
