Line 52:

* 1 new title was added: olsc-sysmodule.

* New services were added, see [[Services_API|here]].

[[SSL_services#CertStore|CertStore]] RomFs: "/ssl_CaFingerprints.bdf" was added and "/ssl_TrustedCerts.bdf" was updated.

===[[USB_services|USB-sysmodule]]===

The only sysmodule with any changes for accessible IO in the [[NPDM]] was USB-sysmodule. The IO page for the [[Fuses|fuse registers]] is now accessible by this sysmodule.

===[[NV_services|nvservices-sysmodule]]===

Among various changes, the [[Switch_System_Flaws#System_Modules|"Transfer Memory leak in nvservices system module"]] system flaw was patched in the following way:

* [[NV_services#Initialize|Initialize]] and [[NV_services#InitializeDevtools|InitializeDevtools]] now keep track of the size of the transfer memory supplied by the user.

* L_34B90 (nvdrv's destructor) now calls L_B4C30 (memset) on the entire transfer memory region (using the size saved previously) before calling [[SVC#svcUnmapTransferMemory|svcUnmapTransferMemory]].

===olsc-sysmodule===

Line 136:

* If svcReturnFromException passes the exception the KDebug, ie. if the argument errorCode is not 0, and if the latter has DontCatchExceptions set, the process is terminated (unless errorCode is 0x10001).

* Performance improvements to svcInvalidateProcessDataCache.

* Redundant calls to smcGetConfig(12) have been reduced (12 calls -> 4 calls) during memory setup

====FIRM Sysmodules====

All FIRM sysmodules were updated. Specific diffs for a few sysmodules are below:

=====[[Loader services|Loader]]=====

* A single null byte stack overflow due to strcat usage was fixed in content path parsing. See [[Switch System Flaws]] for details.

* System Resource Size ([[NPDM]] +0x14) is now allowed to be non-zero for applets in addition to applications.

=====[[Process Manager services|PM]]=====

Memory management initialization was greatly changed:

* PM no longer hardcodes five memory profiles, and no longer calls smcGetConfig to determine which profile to use.

* Instead, PM now uses [[SVC|svcGetResourceLimitLimitValue]] to determine how much space the kernel has allotted for Application + Applet regions and [[SVC|svcGetSystemInfo]] to determine the total physical memory available, and sets the System region size to (Total Memory Size - Application region size - Applet region size - 5 MiB).
