  new `onLocationChange` callback simply adds permissions information, migration of existing
  functionality should only require updating the function signature.
- Added [`GeckoRuntimeSettings.setEnterpriseRootsEnabled`][89.5] which allows
  GeckoView to add third party certificate roots from the Android OS CA store.
  ([bug 1678191]({{bugzilla}}1678191)).
- ⚠️ [`GeckoSession.load`][89.6] now throws `IllegalArgumentException` if the
  session has no [`GeckoSession.NavigationDelegate`][89.7] and the request's `data` URI is too long.
  If a `GeckoSession` *does* have a `GeckoSession.NavigationDelegate` and `GeckoSession.load` is called
  with a top-level `data` URI that is too long, [`NavigationDelgate.onLoadError`][89.8] will be called
  with a [`WebRequestError`][89.9] containing error code [`WebRequestError.ERROR_DATA_URI_TOO_LONG`][89.10].
  ([bug 1668952]({{bugzilla}}1668952))

  of removing it in GeckoView v93. Please use
  [`Autocomplete.StorageDelegate`][89.11] instead.
  ([bug 1691819]({{bugzilla}}1691819)).
- Added [`ALLOWED_TRACKING_CONTENT`][89.12] to content blocking API to indicate
  when unsafe content is allowed by a shim.
  ([bug 1661330]({{bugzilla}}1661330))
- ⚠️ Added [`setCookieBehaviorPrivateMode`][89.13] to control cookie behavior for private browsing
  mode independently of normal browsing mode. To maintain current behavior, set this to the same

  [`GeckoView.onTouchEventForDetailResult`][88.3] to tell information
  that the website doesn't expect browser apps to react the event,
  also and deprecated [`PanZoomController.onTouchEventForResult`][88.4]
  and [`GeckoView.onTouchEventForResult`][88.5]. With these new methods
  browser apps can differentiate cases where the browser can do something
  the browser's specific behavior in response to the event (e.g.
  pull-to-refresh) and cases where the browser should not react to the event
  because the event was consumed in the web site (e.g. in canvas like
  web apps).
  ([bug 1678505]({{bugzilla}}1678505)).

- ⚠️  Refactored `AutofillElement` and `AutofillSupport` into the
  [`Autofill`][72.2] API.
  ([bug 1591462]({{bugzilla}}1591462))
- Make `read()` in the `InputStream` returned from [`WebResponse#body`][72.3] timeout according
  to [`WebResponse#setReadTimeoutMillis()`][72.4]. The default timeout value is reflected in
  [`WebResponse#DEFAULT_READ_TIMEOUT_MS`][72.5], currently 30s.
  ([bug 1595145]({{bugzilla}}1595145))
- ⚠️  Removed `GeckoResponse`

  ([bug 1577005]({{bugzilla}}1577005))
- Added [`GeckoView.setViewBackend`][72.11] to set whether GeckoView should be
  backed by a [`TextureView`][72.12] or a [`SurfaceView`][72.13].
  ([bug 1530402]({{bugzilla}}1530402))
- Added support for Browser and Page Action from the WebExtension API.
  See [`WebExtension.Action`][72.14].
  ([bug 1530402]({{bugzilla}}1530402))
- ⚠️ Split [`ContentBlockingController.Event.LOADED_TRACKING_CONTENT`][72.15] into
  [`ContentBlockingController.Event.LOADED_LEVEL_1_TRACKING_CONTENT`][72.16] and
  [`ContentBlockingController.Event.LOADED_LEVEL_2_TRACKING_CONTENT`][72.17].
- Replaced `subscription` argument in [`WebPushDelegate.onPushEvent`][72.18] from a [`WebPushSubscription`][72.19] to the [`String`][72.20] `scope`.

## v71
- Added a content blocking flag for blocked social cookies to [`ContentBlocking`][70.17].
  ([bug 1584479]({{bugzilla}}1584479))
- Added [`onBooleanScalar`][71.1], [`onLongScalar`][71.2],
  [`onStringScalar`][71.3] to [`RuntimeTelemetry.Delegate`][70.12] to support
  scalars in streaming telemetry. ⚠️  As part of this change,
  `onTelemetryReceived` has been renamed to [`onHistogram`][71.4], and
  [`Metric`][71.5] now takes a type parameter.
  ([bug 1576730]({{bugzilla}}1576730))
- Added overloads of [`GeckoSession.loadUri`][71.6] that accept a map of
  additional HTTP request headers.
  ([bug 1567549]({{bugzilla}}1567549))
- Added support for exposing the content blocking log in [`ContentBlockingController`][71.7].
  ([bug 1580201]({{bugzilla}}1580201))
- ⚠️  Added `nativeApp` to [`WebExtension.MessageDelegate.onMessage`][71.8] which
  exposes the native application identifier that was used to send the message.
  ([bug 1546445]({{bugzilla}}1546445))
- Added [`GeckoRuntime.ServiceWorkerDelegate`][71.9] set via
  [`setServiceWorkerDelegate`][71.10] to support [`ServiceWorkerClients.openWindow`][71.11]
  ([bug 1511033]({{bugzilla}}1511033))
- Added [`GeckoRuntimeSettings.Builder#aboutConfigEnabled`][71.12] to control whether or
  not `about:config` should be available.
  ([bug 1540065]({{bugzilla}}1540065))
- Added [`GeckoSession.ContentDelegate.onFirstContentfulPaint`][71.13]
  ([bug 1578947]({{bugzilla}}1578947))
- Added `setEnhancedTrackingProtectionLevel` to [`ContentBlocking.Settings`][71.14].
  ([bug 1580854]({{bugzilla}}1580854))
- ⚠️ Added [`GeckoView.onTouchEventForResult`][71.15] and modified
  [`PanZoomController.onTouchEvent`][71.16] to return how the touch event was handled. This
  allows apps to know if an event is handled by touch event listeners in web content. The methods in `PanZoomController` now return `int` instead of `boolean`.
- Added [`GeckoSession.purgeHistory`][71.17] allowing apps to clear a session's history.
  ([bug 1583265]({{bugzilla}}1583265))
- Added [`GeckoRuntimeSettings.Builder#forceUserScalableEnabled`][71.18] to control whether or

  [`AutofillElement`][71.20], for representing the virtual tree.
- Added [`GeckoView.setAutofillEnabled`][71.21] for controlling whether or not the `GeckoView`
  instance participates in Android autofill. When enabled, this connects an `AutofillDelegate`
  to the session it holds.
- Changed [`AutofillElement.children`][71.20] interface to `Collection` to provide
  an efficient way to pre-allocate memory when filling `ViewStructure`.
- Added [`GeckoSession.PromptDelegate.onSharePrompt`][71.22] to support the WebShare API.
  ([bug 1402369]({{bugzilla}}1402369))
- Added [`GeckoDisplay.screenshot`][71.23] allowing apps finer grain control over screenshots.
  ([bug 1577192]({{bugzilla}}1577192))
- Added `GeckoView.setDynamicToolbarMaxHeight` to make ICB size static, ICB doesn't include the dynamic toolbar region.

  ([bug 1501108]({{bugzilla}}1501108))
- Removed `setSession(session, runtime)` from [`GeckoView`][70.5]. With this
  change, `GeckoView` will no longer manage opening/closing of the
  [`GeckoSession`][70.6] and instead leave that up to the app. It's also now
  allowed to call [`setSession`][70.10] with a closed `GeckoSession`.
  ([bug 1510314]({{bugzilla}}1510314))
- Added an overload of [`GeckoSession.loadUri()`][70.8] that accepts a
  referring [`GeckoSession`][70.6]. This should be used when the URI we're
  loading originates from another page. A common example of this would be long
  pressing a link and then opening that in a new `GeckoSession`.
  ([bug 1561079]({{bugzilla}}1561079))
- Added capture parameter to [`onFilePrompt`][70.9] and corresponding
  [`CAPTURE_TYPE_*`][70.7] constants.
  ([bug 1553603]({{bugzilla}}1553603))
- Removed the obsolete `success` parameter from
  [`CrashReporter#sendCrashReport(Context, File, File, String)`][70.3] and
  [`CrashReporter#sendCrashReport(Context, File, Map, String)`][70.4].
  ([bug 1570789]({{bugzilla}}1570789))
- Add `GeckoSession.LOAD_FLAGS_REPLACE_HISTORY`.
  ([bug 1571088]({{bugzilla}}1571088))

  ([bug 1573304]({{bugzilla}}1573304))
- Added [`WebNotification`][70.15] and [`WebNotificationDelegate`][70.16] for handling Web Notifications.
  ([bug 1533057]({{bugzilla}}1533057))
- Added Social Tracking Protection support to [`ContentBlocking`][70.17].
  ([bug 1568295]({{bugzilla}}1568295))
- Added [`WebExtensionController`][70.18] and [`WebExtensionController.TabDelegate`][70.19] to handle
  [`browser.tabs.create`][70.20] calls by WebExtensions.
  ([bug 1539144]({{bugzilla}}1539144))
- Added [`onCloseTab`][70.21] to [`WebExtensionController.TabDelegate`][70.19] to handle
  [`browser.tabs.remove`][70.22] calls by WebExtensions.
  ([bug 1565782]({{bugzilla}}1565782))
- Added onSlowScript to [`ContentDelegate`][70.23] which allows handling of slow and hung scripts.
  ([bug 1621094]({{bugzilla}}1621094))
- Added support for Web Push via [`WebPushController`][70.24], [`WebPushDelegate`][70.25], and
  [`WebPushSubscription`][70.26].
- Added [`ContentBlockingController`][70.27], accessible via [`GeckoRuntime.getContentBlockingController`][70.28]
  to allow modification and inspection of a content blocking exception list.

  longer has any effect on [`setFontInflationEnabled`][69.2]
- Add [GeckoSession.LOAD_FLAGS_FORCE_ALLOW_DATA_URI][69.14]
- Added [`GeckoResult.accept`][69.3] for consuming a result without

## v67
- Added [`setAutomaticFontSizeAdjustment`][67.23] to
  [`GeckoRuntimeSettings`][67.3] for automatically adjusting font size settings
  depending on the OS-level font size setting.
- Added [`setFontSizeFactor`][67.4] to [`GeckoRuntimeSettings`][67.3] for
  setting a font size scaling factor, and for enabling font inflation for
  non-mobile-friendly pages.
- Updated video autoplay API to reflect changes in Gecko. Instead of being a
  per-video permission in the [`PermissionDelegate`][67.5], it is a [runtime
  setting][67.6] that either allows or blocks autoplay videos.
- Change [`ContentBlocking.AT_AD`][67.7] and [`ContentBlocking.SB_ALL`][67.8]
  values to mirror the actual constants they encompass.
- Added nested [`ContentBlocking`][67.9] runtime settings.
- Added [`RuntimeSettings`][67.10] base class to support nested settings.
- Added [`baseUri`][67.11] to [`ContentDelegate.ContextElement`][65.21] and
  changed [`linkUri`][67.12] to absolute form.
- Added [`scrollBy`][67.13] and [`scrollTo`][67.14] to [`PanZoomController`][65.4].
- Added [`GeckoSession.getDefaultUserAgent`][67.1] to expose the build-time
  default user agent synchronously.
- Changed [`WebResponse.body`][67.24] from a [`ByteBuffer`][67.25] to an [`InputStream`][67.26]. Apps that want access
  to the entire response body will now need to read the stream themselves.
- Added [`GeckoWebExecutor.FETCH_FLAGS_NO_REDIRECTS`][67.27], which will cause [`GeckoWebExecutor.fetch()`][67.28] to not
  automatically follow [HTTP redirects][67.29] (e.g., 302).
- Moved [`GeckoVRManager`][67.2] into the org.mozilla.geckoview package.
- Initial WebExtension support. [`GeckoRuntime#registerWebExtension`][67.15]
  allows embedders to register a local web extension.
- Added API to [`GeckoView`][70.5] to take screenshot of the visible page. Calling [`capturePixels`][67.16] returns a [`GeckoResult`][65.25] that completes to a [`Bitmap`][67.17] of the current [`Surface`][67.18] contents, or an [`IllegalStateException`][67.19] if the [`GeckoSession`][65.9] is not ready to render content.
- Added API to capture a screenshot to [`GeckoDisplay`][67.20]. [`capturePixels`][67.21] returns a [`GeckoResult`][65.25] that completes to a [`Bitmap`][67.16] of the current [`Surface`][67.17] contents, or an [`IllegalStateException`][67.18] if the [`GeckoSession`][65.9] is not ready to render content.
- Add missing [`@Nullable`][66.2] annotation to return value for
  [`GeckoSession.PromptDelegate.ChoiceCallback.onPopupResult()`][67.30]
- Added `default` implementations for all non-functional `interface`s.
- Added [`ContentDelegate.onWebAppManifest`][67.22], which will deliver the contents of a parsed
  and validated Web App Manifest on pages that contain one.

## v66
- Removed redundant field `trackingMode` from [`SecurityInformation`][66.6].
  Use `TrackingProtectionDelegate.onTrackerBlocked` for notification of blocked
  elements during page load.
- Added [`@NonNull`][66.1] or [`@Nullable`][66.2] to all APIs.
- Added methods for each setting in [`GeckoSessionSettings`][66.3]
- Added [`GeckoSessionSettings`][66.4] for enabling desktop viewport. Desktop
  viewport is no longer set by [`USER_AGENT_MODE_DESKTOP`][66.5] and must be set
  separately.
- Added [`@UiThread`][65.6] to [`GeckoSession.releaseSession`][66.7] and
  [`GeckoSession.setSession`][66.8]

## v65
- Added experimental ad-blocking category to `GeckoSession.TrackingProtectionDelegate`.
- Moved [`CompositorController`][65.1], [`DynamicToolbarAnimator`][65.2],
  [`OverscrollEdgeEffect`][65.3], [`PanZoomController`][65.4] from
  `org.mozilla.gecko.gfx` to [`org.mozilla.geckoview`][65.5]
- Added [`@UiThread`][65.6], [`@AnyThread`][65.7] annotations to all APIs
- Changed `GeckoRuntimeSettings#getLocale` to [`getLocales`][65.8] and related
  APIs.
- Merged `org.mozilla.gecko.gfx.LayerSession` into [`GeckoSession`][65.9]
- Added [`GeckoSession.MediaDelegate`][65.10] and [`MediaElement`][65.11]. This
  allow monitoring and control of web media elements (play, pause, seek, etc).
- Removed unused `access` parameter from
  [`GeckoSession.PermissionDelegate#onContentPermissionRequest`][65.12]
- Added [`WebMessage`][65.13], [`WebRequest`][65.14], [`WebResponse`][65.15],
  and [`GeckoWebExecutor`][65.16]. This exposes Gecko networking to apps. It
  includes speculative connections, name resolution, and a Fetch-like HTTP API.
- Added [`GeckoSession.HistoryDelegate`][65.17]. This allows apps to implement
  their own history storage system and provide visited link status.
- Added [`ContentDelegate#onFirstComposite`][65.18] to get first composite
  callback after a compositor start.
- Changed `LoadRequest.isUserTriggered` to [`isRedirect`][65.19].
- Added [`GeckoSession.LOAD_FLAGS_BYPASS_CLASSIFIER`][65.20] to bypass the URI
  classifier.
- Added a `protected` empty constructor to all field-only classes so that apps
  can mock these classes in tests.
- Added [`ContentDelegate.ContextElement`][65.21] to extend the information
  passed to [`ContentDelegate#onContextMenu`][65.22]. Extended information
  includes the element's title and alt attributes.
- Changed [`ContentDelegate.ContextElement`][65.21] `TYPE_` constants to public
  access.
- Changed [`ContentDelegate.ContextElement`][65.21],
  [`GeckoSession.FinderResult`][65.23] to non-final class.
- Update [`CrashReporter#sendCrashReport`][65.24] to return the crash ID as a
  [`GeckoResult<String>`][65.25].
