Patch Changes

• #252 The Git entrypoint hashes with node:crypto instead of bundling sha.js and its Buffer polyfills, which trims about 120 KB from a Worker that uses it, and the worker-shell modules are minified, shrinking them by 28%. @cloudflare/computer/tools and its ai-sdk, pi-ai and tanstack-ai variants also no longer reference the bundled isomorphic-git, which unbundled loaders such as Node and Vite's dev server used to fetch for them. (56dd6ab) - Thanks @mattzcarey

Minor Changes

• #238 Add experimental onInterrupt: "restart" | "replay" to WorkerJavaScriptBackend, so runs interrupted by a deploy or crash can resume. (22368fc) - Thanks @scuffi

• #251 Add experimental ctx.interrupt() for host module functions, with runtime.pending() and runtime.respond(), so a replayable run can wait for an answer such as an approval. (5db8dd4) - Thanks @scuffi

Patch Changes

• #263 WorkspaceFileStore and WORKSPACE_ROOT are exported from @cloudflare/computer, so code outside the tools can read and write workspace files without its own helper. (a730798) - Thanks @mattzcarey

Minor Changes

• #255 getWorkspace() now returns a lazy client immediately which resolves on the first call. useThink and the Think compatibility methods are removed; @cloudflare/think 0.21 and later take a Workspace as it is. (9cc3119) - Thanks @mattzcarey

• #237 WorkerJavaScriptBackend keeps its Durable Object alive while executions run, and adds a maxCpuMs option. (7415a44) - Thanks @scuffi

• #239 just-bash is now an optional peer dependency and should be installed manually when using @cloudflare/computer/backends/worker-shell. (5980264) - Thanks @mattzcarey

Patch Changes

• #257 getWorkspace() accepts any Durable Object stub whose class has __getWorkspaceStub(), without a cast. (777097a) - Thanks @mattzcarey

• #244 WorkspaceProxy and WorkspaceServiceProxy wake their host Durable Object by name, so ctx.id.name survives a wake caused by a container or Dynamic Worker callback. WorkspaceRef, WorkspaceProxyProps and WorkspaceServiceProxyProps accept an optional name, filled in from ctx.id.name when the backend runs in the host object itself. (b629117) - Thanks @aron-cf

• #241 Workspace, its filesystem, the worker-javascript backend, mounts, agent tools, Git, Assets, and Artifacts are now stable; LegacyContainerBackend is deprecated in favor of ContainerBackend; the container and worker-shell backends, ws:container, sync, and computerd stay experimental. (d950ffe) - Thanks @aron-cf
