Version 1.42.1

Version 1.42.1 is released!

• Fix for a LineageOS boot loop due to Android Studio 3. See https://issuetracker.google.com/issues/64434571 for more details. This wasn't an Open Camera bug, but a problem exposed by any applications using Android Studio 3 (which Open Camera switched to in version 1.42). Google released a fix in build tools 27, which is used in this new release.
• Now targetting Android 8, and new adaptive icon for Android 8 (thanks to Adam Lapinski).
• Hopefully improved quality for Samsund S7 and S7 Edge when using Camera2 API (the default EDGE_MODE and NOISE_REDUCTION modes seem to give poor results, improved by setting EDGE_MODE_OFF and NOISE_REDUCTION_MODE_OFF).
• Various other bug fixes.
