2.10.2 (2018-07-27)

This release reduces the size of the npm package compared to v2.10.1, which was ~20Mb due to the inadvertant inclusion of build files.

2.10.1 (2018-07-20)

This release simplies the installation and quick setup process to do all configuration in JavaScript, provided that React Native is the primary way to interact with your app (rather than having React Native components as a part of a larger native app). See the integration guide updated configuration instructions.

For applications using React Native to serve a few components (but not the whole app), there is a new Enhanced native integration guide with additional configuration steps to ensure every crash is captured and reported.

Bug fixes

  • Fix possible mismatch between session release stage and error report release stage, which could result in inconsistent crash rates on the Releases dashboard as a session was assigned to an incorrect release stage. #260

  • (android) Address javac compiler warnings and intellij inspections #250

  • (cocoa) Upgrade bugsnag-cocoa to v5.16.2:

    • Fix a regression in session tracking which caused the first session HTTP request to be delivered on the calling thread when automatic session tracking is enabled #295

2.10.0 (2018-07-03)

This release alters the behaviour of the notifier to track sessions automatically. A session will be automatically captured on each app launch and sent to

If you use Bugsnag On-Premise, it is recommended that you set your notify and session endpoints via config.setEndpoints(String notify, String sessions) on Android, and config.setEndpoints(notify:sessions:) on iOS. You should also initialise the Android/iOS components by passing a config parameter:

Configuration config = new Configuration("your-api-key-here");
config.setEndpoints("", "");
BugsnagReactNative.start(this, config);
BugsnagConfiguration *config = [BugsnagConfiguration new];
[config setEndpointsForNotify:@""
[BugsnagReactNative startWithConfiguration:config];
