E2B ships e2b 2.62.1 with binary write support and a higher undici minimum

E2B has released version 2.62.1 of its e2b package, with three patch-level changes. The update lets file write calls accept byte arrays and Node.js Buffers, moves the glob dependency to v14, and raises the minimum undici version to 8.12.3.

E2B published e2b@2.62.1 on GitHub with three patch changes. The first updates the glob dependency to v14. The other two change how files are written and which undici version the package requires.

The files.write(), files.writeFiles() and Volume.writeFile() methods now accept Uint8Array values, including Node.js Buffers. Developers handling binary content can pass bytes to these calls directly.

The minimum undici version is now 8.12.3. According to the release entry, that version replaces HTTP/2 connections that stop responding after a stream timeout.

Why it matters if you build agents

Agents that upload generated images, archives or other binary files into a sandbox can pass Buffers straight to the write methods in this version. Teams that install this package or pin undici should confirm their dependency tree resolves to 8.12.3 or later. Stalled HTTP/2 connections after a stream timeout should be less of a problem at that minimum.
