Both the Anthropic TypeScript SDK and the OpenAI Node SDK accept signal as an AbortSignal in per-request options to cancel requests.
When using Jnvoy, developers only need to replace the request URL and change the original Anthropic SDK call to an httpx.post request, adding a provider field to the request body to specify the upstream model provider, with no need to change business logic.
The internal maintenance section of v1.13.0 applied naming normalization to the value of the default API version header.
v1.13.0 added three capabilities to Managed Agents: workflows, multiagent configuration, and thread status filtering.
v1.13.0 added type definitions for unified analytics metrics in Chat and Cowork.
Since all changes in v1.12.1 are maintenance-related and do not involve interface behavior changes, the upgrade risk is extremely low and developers can upgrade with confidence.
The Anthropic official SDK released version v1.12.1.
v1.12.1 adds a check mechanism for Pull Requests to ensure that the changelog is updated synchronously with every PR.
v1.12.1 aligns the package version with the record in uv.lock, which is a normative correction for internal dependency management.
The documentation clarifies that the maximum number of Agent tools is 256.
