@​langchain/core@​1.2.8

Patch Changes

• #11369 d6ad973 Thanks @​hntrl! - fix(langchain): use unified endpoint for gateway

• #11342 3b0e4c4 Thanks @​thushanth-bengre-langchain! - feat(core): mark errors as retryable or not, and stop retrying the ones that aren't

  Retry middleware retried every failure up to maxRetries, including deterministic ones like a bad API key or an unknown model. Retries also nest, so a single such failure could cost dozens of API calls.

  @langchain/core/errors adds stampRetryable(error, retryable) and getRetryable(error). Marking an error leaves its class and shape untouched, so a provider SDK error can be classified without breaking instanceof. getRetryable returns undefined for errors nobody classified, and both are exported so tool authors can mark their own failures.

  modelRetryMiddleware and toolRetryMiddleware now respect the mark by default, and retries stop as soon as one is found rather than each layer spending its own budget. Aborted calls, context overflow, and oversized payloads are marked non-retryable out of the box. Models accept a per-call maxRetries so a surrounding retry loop can take over.

  Behavior change: errors marked non-retryable now fail on the first attempt. Unclassified errors — including any from third-party integrations or custom tools — retry exactly as before. Pass retryOn: () => true to restore the old default. A custom onFailedAttempt replaces the built-in handler and opts out of marking.

@​langchain/core@​1.2.7

Patch Changes

• #11366 c068bbf Thanks @​hntrl! - fix(core,langchain): patch and release core, update peer dependencies

@​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.

@​langchain/core@​1.2.2
