Patch Changes

• #10002 27186c5 Thanks @aditya-gg04! - fix(core): support reasoning/thinking blocks in StringOutputParser

• #10077 05396f7 Thanks @christian-bromann! - feat(core): add ContextOverflowError, raise in anthropic and openai

• #10081 5a6f26b Thanks @hntrl! - feat(core): add namespace-based symbol branding for error class hierarchies

  Introduces createNamespace utility for hierarchical symbol-based branding of class hierarchies.
  All LangChain error classes now use this pattern, replacing hand-rolled duck-type isInstance checks
  with reliable cross-realm Symbol.for-based identity.

  • New LangChainError base class that all LangChain errors extend
  • New createNamespace / Namespace API in @langchain/core/utils/namespace
  • Refactored ModelAbortError, ContextOverflowError to use namespace branding
  • Added ContextOverflowError.fromError() static factory method
  • Deprecated addLangChainErrorFields in favor of LangChainError subclasses
  • Migrated Google provider errors (GoogleError, ConfigurationError, etc.) to namespace branding
  • Updated Anthropic and OpenAI providers to use ContextOverflowError.fromError()

@langchain/google@0.1.1

Patch Changes

• #10076 217d2ed Thanks @hntrl! - fix(google): accept both uppercase and lowercase reasoning effort/thinking level values

  Previously, passing uppercase values like reasoningEffort: "HIGH" or "MEDIUM" would silently
  fail to configure thinking, because convertReasoningEffortToReasoningTokens only matched lowercase
  strings. This caused the thinkingConfig to be omitted entirely from the API request.

  • Normalize effort input to lowercase in convertReasoningEffortToReasoningTokens
  • Extend Gemini.ThinkingLevel type to include lowercase variants for better DX
  • Add LowercaseLiteral utility type to derive lowercase members from the auto-generated API types
