Line 87:

* Compiler upgrade to LLVM 11.1.

** Most notably, certain code now emits "ands" rather than "and; and; tst" + "bfxil" patterns are more commonly used.

* C++ language upgrade to ~~C++20 (or~~ C++17~~, but less likely)~~.

* C++ language upgrade to C++17.

** Slab heaps/object containers are now ~~constinit~~, no longer constructed during .init_array.

** Slab heaps/object containers are now constant initialized, no longer constructed during .init_array.

* Initialize0 changes:

** KernelLdr now sends back the initial process binary address in state.

Line 112:

** These SVCs conceptually allow creating an object for mapping in certain physical address ranges at user-specified virtual addresses, without having to include the ranges in npdm/kip capabilities ahead of time.

*** The only allowed id right now is 0, which corresponds to PCIE_A2 (physical address range 0x12000000-0x1FFFFFFF).

* KLightLock::Lock now uses simplified logic; KLightLock::LockSlowPath now returns a bool for whether the lock was acquired.

* KWritableEvent was deleted.

** Class tokens for types after KWritableEvent have been adjusted downwards to compensate (see mesosphere for class token generation algorithm).

Line 211:

Line 212:

** "Break() called. %016lx\n" and "Exception occurred. %016lx\n" are now "Break() called. " and "Exception occurred. ", respectively.

* StoreDataCacheSharedForInit has slightly different (but equivalent) iteration logic.

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

* New btdrv commands were added.

* A number of funcs now clear stack buffers before sending it elsewhere.

* A number of funcs now [[Switch_System_Flaws|clear]] stack buffers before sending it elsewhere.

* A new system-setting is now used during [[Bluetooth_Driver_services#EnableBluetooth|audio-enabling]].

* ...
