## @expo/spawn-async 1

### New APIs and options

- Pass maxBuffer to limit how many characters or bytes stdout and stderr accept; the command aborts and throws an error when the limit is exceeded. (1.8.0) — [release notes](https://github.com/expo/spawn-async/releases/tag/v1.8.0)

### Behavior and default changes

- stderr is now a getter that concatenates collected stderr chunks on demand. (1.8.0) — [release notes](https://github.com/expo/spawn-async/releases/tag/v1.8.0)
- stdout is now a getter that concatenates collected stdout chunks on demand. (1.8.0) — [release notes](https://github.com/expo/spawn-async/releases/tag/v1.8.0)

### Fixes and other changes

- Prevents exceeding the maximum V8 string length and exposes cut-off stdout and stderr on the corresponding error. (1.8.0) — [release notes](https://github.com/expo/spawn-async/releases/tag/v1.8.0)
