Minor Changes

• 4fcf7cb: Add FileType.SYMLINK to the sandbox filesystem types. Newer envd versions report symlinks with a dedicated FILE_TYPE_SYMLINK entry type; previously the SDKs treated it as unknown, so files.list() silently omitted symlink entries and getInfo()/get_info() returned an undefined/None type for them. Symlinks now surface as FileType.SYMLINK ('symlink') with symlinkTarget/symlink_target populated, in JS and both sync and async Python.

Patch Changes

• 3f46d56: Select template build-step stack-trace frames by SDK boundary instead of fixed depth. The caller's frame is now the first one whose file lies outside the SDK package, so traces stay correct when transpilers inject extra frames (e.g. TS class-field initializers) or runtimes elide delegating frames (e.g. Bun's tail-call elision). The suppress/override stack-trace collection machinery this made redundant (runInNewStackTraceContext, runInStackTraceOverrideContext and their Python equivalents) is removed.
• 1ae3f92: Recognize Cloudflare Workers' Network connection lost as a dropped sandbox connection so a sandbox killed mid-request surfaces as the health-checked TimeoutError (matching Node/Bun/Deno), and fix streaming downloads releasing their pooled connection twice when cancelled while a read was in flight
• 9ee4414: Fix template file uploads under Deno. Deno's native fetch ignores a Content-Length header on stream bodies and fell back to Transfer-Encoding: chunked, which S3-compatible presigned upload URLs reject (see [#1243]). Template.build uploads now stream the spooled archive through undici's fetch, which honors the header on every runtime, falling back to the global fetch where undici isn't resolvable.
• 5e141a7: Fix the Sandbox.getHost() documentation example so it can be copy-pasted. The @example called sandbox.commands.exec(...), which is not a method on the Commands class (it exposes run), so running the snippet threw TypeError: sandbox.commands.exec is not a function. It now uses sandbox.commands.run(..., { background: true }), allowing the long-running HTTP server to start before the example calls getHost(). Documentation only, no behavior change.
• 4fcf7cb: Regenerate API clients from the latest specs, which are now synced with Copybara from their source-of-truth repositories (e2b-dev/infra@e2255f0 for the REST and envd specs, belt for the volume-content spec) instead of being copied by hand. Picks up the latest spec changes: named SandboxTimeoutRequest/SandboxSnapshotRequest/SandboxRefreshRequest request schemas, SandboxNetworkConfig and SandboxIam workload-identity models, the FILE_TYPE_SYMLINK filesystem entry type, and deprecation of access-token auth in favor of API keys. Anything the upstream specs mark x-not-implemented: true (currently the SOCKS5 egress-proxy config) is excluded from the generated clients. Generated Python client models now list fields in spec order instead of alphabetical order (the tag filtering moved from a custom script to Redocly CLI); construct them with keyword arguments if you don't already
• 5417dd4: Bump the minimum tar dependency to 7.5.19 to pull in upstream fixes for node-tar denial-of-service vulnerabilities (GHSA advisories covering PAX parsing, negative entry sizes, and unbounded decompression)
