 ** 0100000000000805(CHN/KOR dictionary), 0100000000000808("European, English and Japanese dictionaries"), 010000000000080A(Chara?), and 010000000000080C(EULA).
 * The following 01000000000008XX titles were added:
-** 0100000000000800(SSL trusted certs), 0100000000000807(Hotspot List), 010000000000081E(Dummy file), 010000000000081F(Icosa system config), 0100000000000820(Copper system config), 0100000000000821(Hoag system config),

-* The System Application "flog" (01008BB00013C000) was added.
+* 010000000000081B ("exFAT FIRM") package2 is no longer "stubbed"/overwritten with garbage.
+===FIRM===
+====Package1====
+The encrypted binaries' order and calculation for next stage's entrypoint was changed.
+Old layout (before 2.0.0):
+.- PK11 header
+.- Secure Monitor blob
+.- NX bootloader blob
+.- Warmboot blob
+ NX bootloader entrypoint is calculated as:
+x40013FE0 + 0x20 + 0x20 + NX bootloader blob's offset + Secure Monitor blob's size
+New layout (2.0.0+):
+.- PK11 header
+.- Warmboot blob
+.- NX bootloader blob
+.- Secure Monitor blob
+ NX bootloader entrypoint is calculated as:
+x40013FE0 + 0x20 + 0x20 + NX bootloader blob's offset + Warmboot blob's size
+Some AES-ECB decryption related code was refactored.
+==Kernel==
+* KPoolManager was majorly rewritten.
+** Added MAC crypto on heap-chunk headers, to protect against DMA attacks (same as 3DS).
+* KHandleTable default size was improved from 40 to 1024.
+* The code to create a bigger handle table in allocated pool memory has been removed.
+* KHandleTable spinlock was given core-suspension logic.
+* KHandleTable compresses 64-bit pointers into 32-bit offsets.
+* KAddressSpace was renamed to KDeviceAddressSpace.
+* KSharedMemory now maintains a list of every map (each 0x20-byte entry).
+** To do cleanup of mapped shared memories when a process is killed.
+* KSharedMemory no longer references the owning KProcess.
+** Instead it stores the pid, so that the process can be freed even though the shared memory still exists.
+* KInterruptEvent changed:
+** Creation doesn't use KIrqSingleton directly anymore.
+** Instead it allocates a 0x20-byte entry, and then uses KIrqSingleton.
+** Probably to do better cleanup.
+* Size-checks >= 0x180000000 was added to a bunch of syscalls.
+* Restriction on debug SVCs were loosened to support [[creport]].
+* svcReadWriteRegister was extended with more registers.
+* Added blacklist on [[NPDM]] kernel descriptor memory mappings.
+* svcGetInfo was extended with more id0's.
+* Process exception dispatching was implemented/improved.
+* Support for processes with 39-bit AddressSpaceType was added.
+** Includes required IPC changes.
+* On startup, kernel now calls SMC id1 0xC3000007 with the kernel memory range start and size.
+* AArch64 exception vector for "SError interrupt" was implemented.
+* Kernel stacks are now allocated with a slabheap.
+* KHeapArrange was changed. On 1.0.0 it held address/size for three pools ("base", "application", "system") and application/system were zero-sized/unused. Now it holds "pool management", "secure", "non-secure". Pool management and secure are now protected by the kernel carveout.
+** Secure pool size is dynamically calculated as size of all kips (including stacks) + 24 MB (FS sysmodule heap) + 1 MB (spare pages for e.g. IPC buffer usage).
+** If only one KIP is present, all memory goes to secure pool and non-secure pool does not exist.
