Bumps @langchain/core from 1.2.2 to 1.2.6.

Release notes

Sourced from @​langchain/core's releases.

@​langchain/core@​1.2.6

Patch Changes

• #11344 f08e0c6 Thanks @​hntrl! - fix: apply [Symbol.hasInstance] method to all comparable properties using .isInstance()

  We have some internal schemas that rely on z.instanceof(). This uses a strict instanceof check which can conflict if there are multiple versions of core installed. This overrides the Symbol.hasInstance method to use the same logic as .isInstance() to compare objects at runtime.

@​langchain/core@​1.2.5

Patch Changes

• #11305 e654022 Thanks @​jacoblee93! - Add LangSmith Gateway environment configuration to OpenAI, Anthropic, and Fireworks chat models.

• #11295 1a1b347 Thanks @​vladislav-nechakhin! - fix(core): pass the mustache escape override per render call

@​langchain/core@​1.2.4

Patch Changes

• #11190 9654bde Thanks @​pawel-twardziak! - Coalesce nested LangChain tracer callbacks that share run bookkeeping.

• #11153 84ce6d6 Thanks @​parveshsaini! - fix(core): bind splitText when trimMessages receives a TextSplitter instance

@​langchain/core@​1.2.3

Patch Changes

• #11200 08e5888 Thanks @​hntrl! - fix(aws): normalize and safely replay Bedrock reasoning blocks

  Emit standard reasoning blocks with preserved signatures, omit incomplete signature-only reasoning during replay, and retain compatibility with legacy and redacted Bedrock reasoning.
