- Fixed `FrameProcessor` freeze and release behavior, was broken ([#431][431])
- New: new api `setAutoFocusResetDelay` to control the delay to reset the focus after autofocus was performed, thanks to [@cneuwirt][cneuwirt] ([#435][435])
- Faster camera preview on layout changes ([#403][403])
- Renames setPreviewSize to setPreviewStreamSize (previewSize suggests it is related to the view size but it's not) ([#393][393])
- Added new APIs `setSnapshotMaxWidth` and `setSnapshotMaxHeight` ([#393][393]). You can now have a good looking preview but still take low-res snapshots using these snapshot constraints. Before this, the two sizes were coupled.
