==== Kernel ====
* Compiler update (Clang 20?)
* KProcess::Run() and CreateThread() SVC now write the current thread handle to [[Thread_Local_Region|TLS+0x110]]
* Changes in and surrounding page table logic:
** KPageTableBase::LockForMapDeviceAddressSpace now checks for a new KPageTableBase boolean, m_allowed_exec_device_mapping, and decides between KMemoryPermission_None and KMemoryPermission_UserExecute for the permission mask value if the boolean is, respectively, set or not.
*** This prevents mapping any executable memory as device memory.
* ...

==== [[Loader_services|Loader]] ====
A new NSO compression method was introduced.

This appears to be a slightly customized variant of zstd and is used when NSO [[NSO0#Flags|flags]] have bit 7 set.
* ZSTD_MAGICNUMBER is set to 0x4349425A (b'ZBIC') instead of standard 0xFD2FB528
* ZSTD_LEGACY_SUPPORT is set to 0
* ZSTD_TRACE is set to 1, the version of zstd used is 1.5.7 (ZSTD_VERSION_NUMBER = 10507)
* The code seems to fully match upstream otherwise

=== [[NFC_services|nfc]] ===
A vuln was [[Switch_System_Flaws|fixed]].

=== [[Creport|creport]] ===
* In nnMain, a check for whether the process is an application was moved before calling the func which loads the DyingMessage data (previously located immediately after).
* The system ProgramIds were updated.
* The [[Error_Report_services|erpt]] field for EncryptedDyingMessage is now additionally only handled with an application process (same data loaded above).

=== BootImagePackages ===
RomFs changes: all files updated.

Using updated master-key: master_key_15 (previously master_key_14). See [[NCA]] for the KeyGeneration listing.

The anti-downgrade fuses were [[Fuses#Anti-downgrade|updated]].

==== Kernel ====
* Changes in and surrounding page table logic:
** KPageTableBase::LockForMapDeviceAddressSpace now checks for a new KPageTableBase boolean, m_allowed_exec_device_mapping, and decides between KMemoryPermission_None and KMemoryPermission_UserExecute for the permission mask value if the boolean is, respectively, set or not.
*** This prevents mapping any executable memory as device memory.
* ...

==== [[Loader_services|Loader]] ====
A new NSO compression method was introduced.

This appears to be a slightly customized variant of zstd and is used when NSO [[NSO0#Flags|flags]] have bit 7 set.
* `ZSTD_MAGICNUMBER` is set to 0x5A424943 (b'ZBIC') instead of standard 0xFD2FB528
* `ZSTD_LEGACY_SUPPORT` is set to 0
* otherwise the code seems to match zstd version ~1.6.0

=== [[NFC_services|nfc]] ===
A vuln was [[Switch_System_Flaws|fixed]].

=== [[Creport|creport]] ===
* In nnMain, a check for whether the process is an application was moved before calling the func which loads the DyingMessage data (previously located immediately after).
* The system ProgramIds were updated.
* The [[Error_Report_services|erpt]] field for EncryptedDyingMessage is now additionally only handled with an application process (same data loaded above).

Thread Local Region

2026-03-18T23:25:17Z

Alu:

This is the 0x200-byte thread local region. Its base address is loaded via ARM threadid register tpidrro_el0. TLR for multiple threads are stored in the same page, with the first TLR normally located at page+0x200, because the first TLR spot is reserved for usermode exception handling. In threads created by sdk, tpidr_el0 is assigned to the ThreadPointer object from the thread local region.
