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.

Every E2B releasee2b@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@2.59.0
Minor Changes e5a9fa6: Add dnsServers to the network options (dns_servers in Python): the DNS servers a sandbox can reach when allowOut contains a domain. Leave it out to allow the default, 8.8.8.8, pass a list of IPs to allow those instead, or pass [] to allow none. It only opens the firewall and doesn't change the sandbox's /etc/resolv.conf.
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.
e2b@2.52.0
Minor Changes 2de0cc3: Cap sandbox fork count at 20. e2b sandbox fork --count, JavaScript Sandbox.fork({ count }), and Python Sandbox.fork(count=...) reject a count outside 1–20 before the API call. Counts from 21 through 100 used to reach the API. Omitting count still leaves the field off the request so the API default applies.
e2b@2.51.0
Minor Changes 5c0f6eb : Remove SDK-side defaults from API request payloads so the API defaults apply when options are omitted. Sandbox create/fork/connect no longer preset a 5-minute timeout, fork no longer presets count: 1 , create no longer presets allow_internet_access , pause no longer presets keeping memory, and template builds no longer preset...
e2b@2.50.0
Minor Changes 5b015ad : Removed the V1 template build operations and schemas from the generated API clients. The API no longer serves them (runtime 87968fc1e1fa ); control planes carrying that change answer 410 Gone . Template builds go through the Template SDK.
e2b@2.49.0
Minor Changes f842aa8 : Expose a configurable minimum free-disk target with minFreeDiskMb in JavaScript, min_free_disk_mb in Python, and --min-free-disk-mb in template create . Omission uses the team default, while explicit zero requests no minimum growth. Growth is best effort and never shrinks an existing filesystem.
