[Release] langchain-ai/langchain langchain==1.3.14: langchain==1.3.14

LangChain version 1.3.14 release includes three key improvements: a fix for the ToolRetryMiddleware to only retry retryable exceptions, a new ToolErrorMiddleware feature for better error handling, and general release updates. This version enhances the reliability and error management capabilities of the LangChain framework for tool execution and middleware processing.

Key Points

• •ToolRetryMiddleware now intelligently filters exceptions to only retry those marked as retryable, preventing unnecessary retry attempts on non-recoverable errors
• •New ToolErrorMiddleware feature introduced for improved error handling in tool execution pipelines
• •Release version 1.3.14 builds incrementally on 1.3.13 with focused bug fixes and feature additions
• •Middleware improvements enhance the robustness of tool execution in LangChain applications
• •Error handling and retry logic refinements reduce unnecessary processing and improve system efficiency
• •These changes support more reliable agent and tool integration patterns in LangChain workflows
