+Subject: build: disable print_content_analysis
+
+Print Content Analysis enables enterprise users to scan to-be-printed
+pages and documents for sensitive data if the OnPrintEnterpriseConnector
+policy is enabled. A conversation with the Chromium team confirmed
+this feature was intended for enterprise Chrome users and not embedders,
+so we're disabling it to prevent build issues/additional unneeded files.
+
+This patch can be removed when enable_print_content_analysis can be more
+easily enabled or disabled by default with buildflags.

patches/chromium/disable_compositor_recycling.patch

@@ -6,7 +6,7 @@ Subject: fix: disabling compositor recycling
 Compositor recycling is useful for Chrome because there can be many tabs and spinning up a compositor for each one would be costly. In practice, Chrome uses the parent compositor code path of browser_compositor_view_mac.mm; the NSView of each tab is detached when it's hidden and attached when it's shown. For Electron, there is no parent compositor, so we're forced into the "own compositor" code path, which seems to be non-optimal and pretty ruthless in terms of the release of resources. Electron has no real concept of multiple tabs per window, so it should be okay to disable this ruthless recycling altogether in Electron.

+Subject: feat: Add data parameter to ProcessSingleton
+
+This patch adds an additional_data parameter to the constructor of
+ProcessSingleton, so that the second instance can send additional
+data over to the first instance while requesting the ProcessSingleton
+lock.
+
+On the Electron side, we then expose an extra parameter to the
+app.requestSingleInstanceLock API so that users can pass in a JSON
+object for the second instance to send to the first instance.

-Subject: feat: Add data transfer mechanism to requestSingleInstanceLock flow
-
-This patch adds code that allows for the second instance to send
-additional data to the first instance, and for the first instance
-to send additional data back to the second instance, during the
-app.requestSingleInstanceLock call.
-
-Firstly, this patch adds an additional_data parameter
-to the constructor of ProcessSingleton, so that the second instance
-can send additional data over to the first instance
-while requesting the ProcessSingleton lock.
-
-Then, we add additional processing to the second-instance event, both
-so the first instance can receive additional data from the second
-instance, but also so the second instance can send back additional
-data to the first instance if needed.

+Subject: feat: replace ad-hoc SetPublicFirstPartySets calls with method in
+ ContentBrowserClient
+
+Cherry-picked from upstream Chromium. This patch can be removed when the
+fix is inherited from the next Chromium roll backport.
+
+This essentially requires
+embedders to indicate whether they will
+(maybe asynchronously) call SetPublicFirstPartySets during startup, or
+not. This makes it easier to initialize First-Party Sets properly, since
+it is now done via a pull-based interface rather than a push-based
+interface (which would require code in every embedder in order to
+set up the First-Party Sets backend). Now, there is a single place (in
+content) that handles every embedder that won't need to explicitly call
+SetPublicFirstPartySets at some point (e.g. after initializing
+Component Updater, in Chrome's case).

+Subject: fix: adapt exclusive_access for electron needs
+
+This patch is necessary in order to properly enable
+navigator.keyboard.{(un)?lock}() functionality. We don't have a concept
+of PermissionManager nor of a Profile, so this would not affect usage of
+the API.
+
+We also need to ensure that NotifyExclusiveTabAccessLost is called
+on all platforms in FullscreenController::ExitFullscreenModeInternal()
+and not just macOS, since Electron's native window impls report state
+change fairly instantly as well, and so pressing escape won't work on
+Linux or Windows to un-fullscreen in some circumstances without this
+change.
