==Change-log==
This is the [http://en-americas-support.nintendo.com/app/answers/detail/a_id/22525/p/897 official changelog] from Nintendo regarding this update:

'''Improvements Included in Version 2.1.0'''
*General system stability improvements to enhance the user's experience

==System Titles==
Exactly the following [[Title_list|titles]] were updated:
* The following sysmodules were updated: 
** nifm
** ptm
** hid
** wlan
** nvservices
** nvnflinger
** ns
** am
** nim
** erpt
** pctl
** eupld
** fatal
** creport (See [[Creport|here]] for changes)
* The only updated 01000000000008XX titles are: [[Internet_Browser|shareddata]], 0100000000000816, FIRM-packages(see below), and [[System_Version_Title]].
* The only updated 01000000000010XX titles are: "System applet"(qlaunch), 0100000000001008, 010000000000100A, [[Internet_Browser|ShopN]], 010000000000100F, [[Internet_Browser|Whitelisted-applet]], and [[Internet_Browser|WifiWebAuthApplet]].

===[[Internet_Browser|Browser]]===
A browser vuln was [[Switch_Userland_Flaws|fixed]], see also [[Internet_Browser|here]] for v2.1 browser details.

===[[Title_list|FIRM]] Packages===
The only changes in titles 0100000000000819 and 010000000000081A was that "/nx/package2" in the FS were updated. 010000000000081B firm was also updated.

819:

Kernel was not changed.

Sysmodules:
* All 3 codebin sections in the following sysmodules were updated: boot, FS, Loader, and NCM. Offset of the RW section for FS increased by 0x1000.
* For ProcessMana and sm, only the RO section changed. The only change was the builid hash at the very end of the section, following the "GNU" string.
* spl wasn't updated.
** Loader: Only changes in .text was a rebuild with latest SDK, now has the same additional IPC cmd code as NS(see below).
** boot: .text now has latest SDK changes + various other changes.

====FS-module====
There were two changes with [[Filesystem_services#IDeviceOperator|IDeviceOperator]] commands:
* Code eventually executed for cmd216 was updated. Instead of directly writing to the output struct which is then copied to final output later, a tmpbuf is used which is then copied to the output struct. The 0x10-byte output struct is cleared at the start, and the only u16s copied to output struct from tmpbuf when successful are: +0, +4, +8, +14, and +12.
* New command 217 was [[Filesystem_services#IDeviceOperator|added]].
* See also below SDK section.

Rest of the changes:
* HFS0 error handling was updated.
* The error returned in one case for a certain func was changed.
* Code was moved into a separate func, which is now called by the func which was using that code. Similar-ish code in a different func was removed.
* A certain func no longer writes an error to stack.
* Various memwrite/memclear changes.
* Various u16 counters are now incremented in some cases.
* In a certain func an u32 field is now incremented at _this+16 in some cases.
* Minor other change(s).

===SDK===
Every system-title with this system-version which uses FS now has IPC code for using the new IDeviceOperator cmd, including FS-module itself.

=== Application crashes ===
As documented [[Creport|here]], a fatal-error is no longer thrown when applications crash. Instead, [[qlaunch]] displays an error message, without requiring a reboot. It appears [[2.0.0]] qlaunch already had the message string for this, which is: "The software was closed because an error occurred."

===erpt===
...

The following strings were added to the codebin: "GameCardInsertionCount", "GameCardRemovalCount", and "GameCardAsicInitializeCount".

===[[NV_services|nvservices]]-sysmodule===
Only 1 func was changed: L_30f20, which is at L_30f20 in prev ver.

Strings containing paths were changed. For example, "'''D:/Home/teamcity/work/hr'''/3rdparty/hos-ddk-minimal/ddk/Programs/Chris/Include\nn/spl/spl_Api.h" is now "'''C:/dvs/git/dirty/git-master_hos'''/3rdparty/hos-ddk-minimal/ddk/Programs/Chris/Include\nn/spl/spl_Api.h".

Also, "'''D:/Home/teamcity/work/hr'''/hos/services/src/libs/nnmem/mem_StandardAllocator.cpp" is now "'''C:/dvs/git/dirty/git-master_hos'''/hos/services/src/libs/nnmem/mem_StandardAllocator.cpp", etc.

===[[NS_Services|NS]]-sysmodule===
The NS-sysmodule was updated. 4 new funcs were added and 29 funcs were updated.

The ASLR'd codebin base(rtld+0) for the below addrs is 0x6f0c00000. For "prev ver" it's 0x5381800000.

  L_6f0c26f84
  new func.
  called via vtable funcptr.
  return L_6f0c2814c(inx0+8, inx1, w2=0xd9) & 0xffffffff;
  
  L_6f0c2814c
  inx0=_this inx1=0x40-byte outbuf copied from cmdreply inw2=cmdid
  new func.
  Sends an ipc cmd, service unknown.
  only called by L_6f0c26f84.
  
  L_6f0c373f4
  updated, prev ver @ L_5381837284.
  For the func call executed from the first branch(L_6f0c377e8()), x1 and x2 are now set: x1 = *(0x6f0d9d000+0xfc0)+0x90, x2 = 0x6f0d44000+0xb36("ncm")
  
  L_6f0c377e8
  updated, prev ver @ L_5381837640.
  Basically, instead of hard-coded inputs for various stuff, code now loads those using the additional input params.
  
  L_6f0c378b4
  updated, prev ver @ L_538183771c.
  ipc related func.
  After the first func call, instead of "if(inx0==0 || ret^1)return;" this now just does "if(ret==0)return;" and "objptr = *(inx0+32);" afterwards.
  The code at the end was replaced with code for calling a vtable funcptr from the objptr.
  
  L_6f0c379fc
  updated, prev ver @ L_5381837874.
  Instead of writing 0 to sp8, this now writes *(inx0+32) there.

  updated, prev ver @ L_5381837904.
  Same change as L_6f0c379fc.
