e2b@2.63.0
Version 2.63.0 of e2b adds a strict mode to the pause function, preventing sandbox pauses if the guest agent is unresponsive.

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@2.59.0
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.
