v6.2.0 - 2020-10-08T08:12:30

  • Create date formatters at init time to avoid potential race conditions. 807

  • Refactor OOM handler to be less suceptible to data loss on crash. 804

v6.1.4 - 2020-09-14T10:02:17

Bug fixes

  • Copy the metadata observer list rather than mutating it directly. 796

  • Reorganized the project file 793

  • Removed some magic values and used the const string references instead. #792

  • Added BSGJSONSerializer, which ensures no exceptions get thrown (NSErrors get returned instead) 791

  • Guard against non-string metadata map keys #790

  • Quiet some Analyzer false positives #789

  • Avoid crash reporting OOMs if nil provided as codeBundleId #784

v6.0.0 - 2020-06-22T14:53:02

This version contains many breaking changes. It is part of an effort to unify our notifier libraries across platforms, making the user interface more consistent, and implementations better on multi-layered environments where multiple Bugsnag libraries need to work together (such as React Native).

Please see the upgrade guide for details of all the changes and instructions on how to upgrade.

  • Fixes typo in BSG_KSCDeleteOnSuccess enumeration #317

  • Add a breadcrumb when Bugsnag first starts with the message "Bugsnag loaded" #445

  • BugsnagMetaData is now BugsnagMetadata, including the configuration and event fields #450

  • BugsnagCrashReport is now BugsnagEvent #449

  • Add a configuration option to filter breadcrumbs by type. Use config.enabledBreadcrumbTypes to enable or disable particular types of breadcrumbs from being captured. #476

  • Added a designated initializer to BugsnagConfiguration and removed functionality from the default convenience init() to ensure that apiKey has a value set. The apiKey must now be a correctly formatted one to be accepted.

    • Swift: BugsnagConfiguration(_ apiKey)
    • Objective C: [[BugsnagConfiguration alloc] initWithApiKey:]

    #446 #492

  • Support editing breadcrumbs within an Event as objects. Breadcrumbs can now be inspected and modified from callbacks, for example:

    Bugsnag.notifyError(error) { event in
        event.breadcrumbs?.forEach({ crumb in
            if crumb.message == "something specific" {
                crumb.message = "[redacted]"
            }
        })
    }
    

    #474

  • Bugsnag.addAttribute:value:tab: is now Bugsnag.addMetadataToSection:key:value: #454

  • [Bugsnag clearTab:] is now [Bugsnag clearMetadataInSection:] (Swift: Bugsnag.clearMetadata(section:)) #457

  • Renamed callback functions in the Configuration class:

    • beforeSendBlocks is now onSendBlocks (add using config.add(onSend: { ... }))
    • beforeSendSessionBlocks is now onSessionBlocks (add using config.add(onSession: { ... }))
  • Added [Bugsnag clearMetadataInSection:withKey:] (Swift: Bugsnag.clearMetadata(section:key:)) #462

  • Added Bugsnag.getMetadata(_ section). The behaviour is: calling with a valid section name will return the metadata for that section if it exists, or nil if it does not exist. Other, similar functionality (e.g. BugsnagConfiguration.getTab() has been renamed and had usage aligned with this change. #459

  • Added Bugsnag.getMetadata(_ section: key:) #463

  • Add a per-Event apiKey property. This defaults to the global BugsnagConfiguration value but can be overridden in event passed to the Bugsnag.notify() callback. #458

  • Added Bugsnag.context, replicating the BugsnagConfiguration property. This is mutable and may be changed at any point. Changes are propagated to the BugsnagConfiguration property. #466

  • Bugsnag.stopSession() is now Bugsnag.pauseSession(). This renaming has also been applied to the BugsnagNotifier and BugsnagSessionTracker classes. #464

  • Add a breadcrumb when network connectivity changes #448

  • Breadcrumbs now take a message parameter that can now be arbitrarily long. This simplifies breadcrumb creation using Bugsnag.leaveBreadcrumb(string) so that the value is prominently displayed and is not truncated. #433

  • Add metadata accessor methods to BugsnagEvent #465

  • Added a user-configurable enabledErrorTypes property to BugsnagConfiguration. The BugsnagErrorTypes property allows users to choose which types of events are reported. If automatic crash detection is disabled this value is ignored. User-generated notify() events are reported in all cases. #477 #561

  • Internal logging has been unified. Where before two preprocessor macros were required to configure both Bugsnag and KSCrash portions, now the Bugsnag BSG_LOG_LEVEL macro is sufficient to configure both. This should be set on the Bugsnag framework build target. Further configuration instructions can be found in the BugsnagLogger.h header. #472

  • Added a method to allow merging supplied and existing Event metadata. BugsnagMetadata.addMetadataToSection:values: allows Event callbacks to modify Event metadata en-mass. Supplied metadata should be a JSON-serializable dictionary. The resulting Event metadata is the result of applying the following rules to the existing metadata for each supplied value:

    • Non-null values replace any existing key/value pair.
    • Null values remove a key/value pair.
    • Invalid values are logged and ignored. #470
  • Remove Bugsnag.configuration()?. All access to the configuration object should be performed prior to calling Bugsnag.start().

  • User information is now persisted between application runs by default. When set a users' email, id and name are set on BugsnagConfiguration they are stored in the User Defaults and restored if an application is restarted. The values are also copied to the configuration metadata. #469 #590

  • Added callback-free method to leave breadcrumbs: [Bugsnag leaveBreadcrumbWithMessage:metadata:andType] (Swift: Bugsnag.leaveBreadcrumb(_, metadata:, type:)) #482

  • Added removeOnSessionBlock() methods to both Bugsnag and BugsnagConfiguration to allow removal of callbacks run when a session starts. #483

  • Added addOnSendBlock:, removeOnSendBlock: to BugsnagConfiguration. #485 #485

  • Enhanced device orientation change breadcrumbs. These are now reported with "from" and "to" values in a form consistent with the Android notifier. #486

  • The metadata interface is now consistent across the Bugsnag, BugsnagMetadata, BugsnagConfig, BugsnagClient and BugsnagEvent classes. #513

  • BugsnagClient now takes a shallow copy of the configuration passed in on initialisation. #524

  • The bundleVersion property is available on BugsnagConfiguration allowing overriding the default plist value. #550

  • Deliver each event in a separate request to avoid exceeding payload size limit #424
