## Body
E2B releases published @e2b/code-interpreter@2.9.1. This automated release-watch entry was generated from the project's official GitHub release feed and is kept separate from human-reviewed editorial analysis. Release notes: Patch Changes 8cc9ed1 : Document that logs.stdout , logs.stderr and OutputMessage.line hold raw chunks with newlines kept (join them with '' to rebuild the output), and that Result.png , Result.jpeg and Result.pdf are base64-encoded. 7d10433 : Fix readLines quadratic line reassembly when streaming long single-line outputs (e.g. base64 images, wide DataFrames, large JSON): decode and scan only each new chunk, accumulating line fragments in an array that is joined once per emitted line, instead of appending to and re-scanning a single string buffer on every chunk. ac0727b : Fix OutputMessage.timestamp in the JS Code Interpreter to use the backend timestamp (Unix epoch in nanoseconds) sent with each stdout/stderr message, instead of the client clock ( new Date().getTime() 1000 ). The type is unchanged ( number ); this aligns the value with the documented contract and the Python SDK.…
