 # Backtrace Unity Release Notes

The Backtrace Configuration now exposes a setting for games being prepared for iOS to choose `Capture native crashes`. When enabled, the backtrace-unity client will capture and submit native iOS crashes to the configured Backtrace instance. To generate human readable callstacks, game programmers will need to generate and upload appropriate debug symbols.
+- Added default uname.sysname attributes for some platforms. The following is the list of uname.sysname platforms that can be populated. list "Android, IOS, Linux, Mac OS, ps3, ps4, Samsung TV, tvOS, WebGL, WiiU, Switch, Xbox". Note 'Switch' had previously been reported as 'switch'
+- Added a new attribute 'error.type' that allows developers to quickly filter error reports based on the type of error - The list includes "Crash, Message, Hang, Unhandled Exception, Exception".
+- Updated Android NDK libraries used by Unity plugin.
