Anthropic's TypeScript SDK ships weekly, tracking new agent and API surfaces

sdktypescriptai-agentsapi-clientsagent-memory
◆Current state
This is a genuine release changelog for Anthropic's TypeScript SDK family (core, AWS Bedrock, and Vertex bindings). The cadence is high and incremental: most releases add support for newly shipped API capabilities, notably around managed agents, streaming, and memory, with periodic housekeeping. Recent versions add an agent-memory beta header and a broad managed-agents feature set (event delta streaming, agent overrides, reverse pagination, vault credential injection scoping, and deployment webhooks).
◆Where it's heading
The SDK is clearly tracking a server-side push into agent infrastructure: memory, managed agents, deployment webhooks, and credential scoping are all agent-platform primitives surfacing as client bindings. The Bedrock and Vertex packages move in lockstep with smaller plumbing changes, so the direction is a steadily widening agent API being made first-class in the TypeScript client.
◆Prediction
Expect continued fast minor releases exposing more managed-agent and memory endpoints as the underlying API expands; the SDK will keep trailing server-side agent features by days rather than leading them.
