~~<fill this in~~ (~~manually~~) ~~later>~~

* Every sysmodule (besides stubs) were updated.

* All SystemData was updated, except for the Dictionary titles, AvatarImage, Eula, ControllerIcon, ApplicationBlackList, FunctionBlackList.

* All applets were updated, except for LibraryAppletCabinet, LibraryAppletSwkbd, LibraryAppletMiiEdit.

The only NPDM changes besides the usual version-bump was adding [[SPL_services|csrng]] service access to the [[Internet_browser|web-applets]]: LibAppletWeb, LibAppletShop, LibAppletOff, LibAppletLns, LibAppletAuth.

There were no sysmodule IPC changes.

The ssl sysmodule codebin was not changed.

RomFS changes:

* ErrorMessage: various error messages were updated/added.

* BrowserDll:

** Added "/browser/certBlocklistCommon.json".

** Updated "/browser/ErrorPageTemplate.html", "/browser/MediaControlsInline.css", "/browser/MediaControlsInline.js", "/browser/RootCaEtc.pem", "/buildinfo/buildinfo.dat".

** Updated "/lyt/Browse/Pointer.arc" and message data.

** "dll_0"/"dll_1" in "/nro/netfront/" were renamed to "core_0"/"core_1".

* Help: "/legallines.htdocs/index.html" was updated.

* LocalNews: Message data was updated.

* UrlBlackList: "/listLnsChina.txt" was updated.

* ControllerFirmware: "/FirmwareInfo.csv" and "/ukyosakyo_ep2_ota.bin" were updated.

* Various UI/graphics/message data was updated for applets.

* Web-applets: "/.nrr/dll.nrr" was renamed to "/.nrr/modules.nrr", and "/buildinfo/buildinfo.dat" was updated.

* photoViewer: "/http/js/index.js" and "/http/styles/index.css" were updated.

===BootImagePackage===

All files in RomFS were updated.

===[[USB_services|usb]]===

The only change was updating the [[USB_services#HidGamepad|json]].

===[[Bluetooth_Driver_services|bluetooth]]===

The func for [[Bluetooth_Driver_services#DisableBluetooth|DisableBluetooth]] was updated. Two funcs which handle [[Bluetooth_Driver_services#FatalReason|FatalReason]] no longer clear a global state field.

The remaining changes fixed IPC cmd [[Switch_System_Flaws|vulns]].

===[[Internet_Browser|Web-applets]]===

The [[11.0.0|CFI]] code was updated.

The add/sub instruction was replaced with eor. Hence, the additional code at func entry/exit is now identical. The code now does:

* The low 40-bits of x30 are extracted, then multiplied with x18.

* <code>crc32x w17, w16, x17</code> (which uses the above value - x16 was set to sp after the above bitfield-extract)

* x17 is multiplied with x18 again.

* <code>crc32x w17, wzr, x17</code>

* Then lastly the eor instruction is used with x30, with x17 shifted to bit40.

A vuln with RNG was [[Switch_System_Flaws|fixed]].
