## Human Summary
E2B patch release 2.62.1 adds Uint8Array/Buffer support for file write APIs and updates dependency versions for glob and undici.

## Agent Summary
E2B version 2.62.1 enables files.write() , files.writeFiles() , and Volume.writeFile() to accept Uint8Array (including Node.js Buffer ). It also upgrades glob to v14 and updates the minimum undici version to 8.12.3 to resolve HTTP/2 connection hangs following stream timeouts.

## Body
E2B released patch version 2.62.1 with several internal updates and API improvements. Specifically, file writing methods ( files.write() , files.writeFiles() , and Volume.writeFile() ) now support Uint8Array data, including Node.js Buffer instances. The release also updates the glob dependency to version 14 and raises the minimum undici requirement to 8.12.3 to replace HTTP/2 connections that fail to respond after a stream timeout.

## Recommended actions
- Upgrade the e2b package to version 2.62.1 or higher.
- Adopt Uint8Array or Node.js Buffer directly in files.write() , files.writeFiles() , and Volume.writeFile() calls if needed.
