New Features

OAuth 2.1 Provider for MCP Connectors: The release adds OAuth 2.1 support for MCP (Model Context Protocol) connector authentication, expanding integration capabilities and improving security posture for third-party connections.

Slack Ephemeral Message Tool: A new ephemeral message send tool has been added for Slack integration, allowing workflows to send temporary messages visible only to specific users. This complements existing Slack messaging capabilities with more targeted communication options.

Bug Fixes

The v0.5.96 release addresses several stability improvements:

• Slack Event Handling: Fixed handling of reaction_added and reaction_removed event payloads to ensure proper reaction-based trigger execution
• Log Display: Replaced stale initialData with placeholderData in log details to fix display issues with workflow execution logs
• Copilot Block Extraction: Improved negated operation condition handling in block configuration extraction for better workflow automation

What Developers Need to Know

Developers using Slack integration should update to benefit from improved event payload handling. Teams implementing OAuth-based MCP connectors can now leverage OAuth 2.1 flows for enhanced security. The fixes address runtime and display issues that may have affected workflow reliability and debugging capabilities.
