E2B has released version 2.58.0 of its Python SDK, which adds a way to stream input into running commands and PTY sessions. The release also removes Python 3.10 compatibility code.

The main change is a new streaming input call for sandbox commands and PTYs. In the JavaScript SDK, sandbox.commands.streamInput(pid) and sandbox.pty.streamInput(pid) return a CommandInputHandle that sends input in order through a single StreamInput call.

The Python SDK gets its own version with different shapes. The async stream_input(pid) returns an AsyncCommandInputHandle, while the sync stream_input(pid, data) blocks until it has sent an iterable of input.

A patch-level change removes compatibility shims for Python 3.10, since the package already requires Python 3.11 or later. The release is dated 20 Oct on GitHub.

## Why it matters if you build agents

Agents that drive interactive programs or terminals can now send stdin or PTY input as a stream through one handle instead of separate calls.

Projects that still run Python 3.10 cannot rely on this SDK, because the package already requires Python 3.11 or later.
