E2B releases version 2.57.0 with a TLS option for egress proxies

E2B has released e2b@2.57.0. The minor change adds a tls option to the egress proxy settings, which accepts either true or an object with optional serverName and caCert fields. In Python, these are exposed as server_name and ca_cert.

The getInfo and get_info calls now report the TLS setting, but they do not return the CA certificate.

Patch-level changes bump @bufbuild/protobuf to ^2.16.0 and share the process kill implementation between commands and PTY. The CLI's --language option parser is now shared between template init and template migrate, and unused internal exports were removed.

If your agents send outbound traffic through an egress proxy that needs a custom CA or a server name, you can now set that in the E2B options instead of working around it.

Call getInfo or get_info to confirm the TLS setting is applied, keeping in mind that the CA certificate is not returned.

The other changes are internal refactors and a dependency update, so they are unlikely to need action in your code.
