e2b@2.62.0
The E2B SDK now supports non-buffered output for commands and streaming file uploads. These changes improve memory efficiency by avoiding buffering large data chunks in the sandbox.
e2b@2.61.0
E2B now supports idempotency keys for sandbox creation in both JavaScript and Python SDKs. This ensures that sandbox creation requests can be safely retried without unintended side effects.
e2b@2.60.0
E2B released e2b@2.60.0, introducing automatic retries for Should-Retry control-plane API errors and status codes 429/502/503/504, bumping undici to address CVE-2026-109869, and improving sandbox creation handling.
e2b@2.59.0
This release adds DNS server configuration options for sandboxes and deprecates specific connection URL environment variables in favor of a unified endpoint.
e2b@2.58.0
Minor Changes 3c4c7cf: - JS: sandbox.commands.streamInput(pid) / sandbox.pty.streamInput(pid) return a CommandInputHandle that sends ordered stdin/PTY input over one StreamInput RPC. Python async: stream_input(pid) returns an AsyncCommandInputHandle; Python sync: stream_input(pid, data) blocks while it sends an iterable of input.
e2b@2.57.0
Minor Changes a1ad326: Add tls to the egress proxy options as true or { serverName?, caCert? } (server_name/ca_cert in Python); getInfo/get_info reports it without the CA.
e2b@2.56.0
Minor Changes 6a74c39: Require Node.js 22.19.0 or newer and depend on undici@^8 only (undici 7 is dropped). undici 8 respects the server's HTTP/2 SETTINGS_MAX_CONCURRENT_STREAMS and opens more connections when one is saturated.
e2b@2.55.0
Minor Changes b52cd30: Add mode: 'full' | 'filesystem' (exported as the SnapshotMode type) to createSnapshot / create_snapshot. With 'filesystem', only the filesystem is persisted: the snapshot is smaller and faster to take, and sandboxes created from it cold-boot (start fresh from disk) instead of restoring memory.
