 # Changelog
+## 1.12.0
++ Support was added for 23.0.0.
++ Special thanks to @alula for handling the implementation of several kernel changes.
+  + The console should boot and atmosphère should be fully functional.
+  + **Please note**: As a result of changes made to nintendo's software in 23.0.0, there is even less memory available for custom system modules.
+    + The amount of memory we can steal from the applet pool has been reduced beyond 7MB and we can no longer launch browser applets (e.g.: eshop) without crashing.
+    + To compensate for this, a set of patches for the browser applets has been introduced.
+      + Thanks to the redesign of the browser applets in 22.0.0 there are only 3 applets we need to worry about: systemWeb, openWeb and LibAppletOff.
+      + With the added burden of maintaining patches for these applets, we can reclaim around 9MB of reserved memory by patching out their allocations.
+      + This memory is provably unused and stealing it should not affect the browser applets in any way as the applets themselves tag it as reserved and never access it.
+      + As a result, the memory available for custom system modules has been experimentally increased to 16MB.
+      + Preliminary testing has seemingly shown no downsides to the overall functioning of the OS and the browser applets in particular.
+      + Nonetheless, please report any issues you may face to ensure no edge cases have been missed and to determine if the memory amount needs to be adjusted. 
+      + These patches may be deprecated at any point in the future if a better solution is devised.     
+  + `exosphère` was updated to reflect the latest official secure monitor behavior.
+    + A new ConfigItem was added to the secure monitor for the first time since firmware 5.0.0.
+  + `mesosphère` was updated to reflect the latest official kernel behavior.
+    + The kernel now supports a 42bit wide address space.
+    + A new memory region dubbed ShadowStack has been introduced.
+    + Kernel RNG was changed to CTR-DRBG.
+  + `boot` was updated to reflect the latest official behavior and to implement a previously missing change.
+    + The way battery i2c shutdown was being enabled changed in firmware 18.0.0 and we missed it.
+    + It is possible this might have been related to a known battery draining issue reported to have started around firmware 18.0.0. Further testing will be needed to confirm.
+  + `loader` was updated to reflect the latest official behavior.
+  + `erpt` was updated to reflect the latest official behavior.
+  + `pgl` was updated to reflect the latest official behavior.
+  + `ro` was updated to reflect the latest official behavior.
+    + NROs can now be lz4 frame compressed.
++ ZBIC compresison/decompression has been properly implemented. Applications using it should now launch and work properly.
++ A dockerfile has been added to atmosphère (thanks @alula).
++ R_DISCARD macro has been adopted across the entire codebase where applicable. This finishes the work started in version 1.10.0 and eliminates the nodiscard warnings during compilation.
++ General system stability improvements to enhance the user's experience.
+## 1.11.2
++ Basic support was added for 22.5.0.
++ Atmosphère was updated to use GCC 16/newlib (latest devkitA64/devkitARM releases).
++ General system stability improvements to enhance the user's experience.
+## 1.11.1
++ Basic support was added for 22.1.0.
++ General system stability improvements to enhance the user's experience.
+## 1.11.0
++ Support was added for 22.0.0.
++ Special thanks to @alula for handling a large chunk of the necessary kernel, loader and erpt changes.
+  + The console should boot and atmosphère should be fully functional.
+  + **Please note**: A change in how applications/applets' lifespan is managed broke the homebrew ecosystem.
+    + All applications and applets are expected to perform a clean exit by calling the relevant IPC commands.
+    + Homebrew compiled with libnx and hbmenu itself explicitly avoid exiting so it can keep using the same process.
+      + Properly fixing this would require a re-design of how homebrew is launched and terminated.
+    + As a temporary solution, patches to the `am` sysmodule are now included which allow restoring the previous behavior and regain homebrew compatibility without any further changes.
+    + Nonetheless, please report any issues you may face when testing homebrew to ensure no edge cases have been missed.    
+  + `exosphère` was updated to reflect the latest official secure monitor behavior.
+  + `mesosphère` was updated to reflect the latest official kernel behavior.
+  + `loader` was updated to reflect the latest official behavior.
+  + `erpt` was updated to reflect the latest official behavior.
+  + `pgl` was updated to fix a few issues.
++ Support was added for memory modes above 4GB (thanks @CTCaer).
++ A build time option to configure Joy-Con rails as UART for debugging was added (thanks @alula).
++ General system stability improvements to enhance the user's experience.
+## 1.10.2
++ Basic support was added for 21.2.0.
++ General system stability improvements to enhance the user's experience.
+## 1.10.1
++ Basic support was added for 21.1.0.
++ A bug was fixed that caused some games (e.g. Tomb Raider definitive edition) to fail to launch.
++ General system stability improvements to enhance the user's experience.
+## 1.10.0
++ Basic support was added for 21.0.0.
+  + The console should boot and atmosphère should be fully functional.
+  + **Please note**: All homebrew software may need to be re-compiled with the latest libnx (>= 4.10.0), or else it may crash/experience memory corruption.
+    + Nintendo broke the userland<->kernel TLS ABI in 21.0.0, by writing to previously reserved space.
+    + Homebrew used this reserved space for its TLS slots, which means any homebrew software using TLS slots will experience memory corruption when running under Atmosphere 1.10.0.
+    + This doesn't appear to impact everything, but a large portion of tested homebrew crashes (often on exit), and so will need re-compile for the new ABI.
+      + For those technically inclined, while TLS slots are rarely used by developers, they're used to implement features like e.g. C++ exceptions under the hood, and so anything using those crashes, etc.
+    + To help make this transition easier, hbmenu now shows a warning when selecting homebrew compiled with an older, incompatible ABI version.
+      + I apologize for the hassle in general.
+      + libnx has been updated so that its reserved space matches Nintendo's now -- this particular issue can never occur again, even if Nintendo touches more reserved space.
+  + `exosphère` was updated to reflect the latest official secure monitor behavior.
+  + `mesosphère` was updated to reflect the latest official kernel behavior.
+  + `loader` was updated to reflect the latest official behavior.
+  + `pm` was updated to reflect the latest official behavior.
+  + `erpt` was updated to reflect the latest official behavior.
+  + `pgl` was updated to reflect the latest official behavior.
+  + `fatal` was updated to reflect the latest official behavior.
++ Support was added for launching another game-which-has-too-many-files with romfs mods.
+  + I rely on user reports for adding support/fixing these, and some of these games can be pretty obscure!
+  + If you are affected by this, you will see "Data abort (0x101)" when trying to launch the game with mods.
+  + Please reach out to `sciresm` on discord if this occurs to share your error report binary.
+    + Although some games may be impossible to fix, I believe I can get almost everything working, so please let me try to help you (and improve atmosphère's support!) if you run into this!
++ General system stability improvements to enhance the user's experience.
+## 1.9.5
++ Basic support was added for 20.5.0.
++ General system stability improvements to enhance the user's experience.
+## 1.9.4
++ Basic support was added for 20.4.0.
++ An issue was fixed in `exosphère`'s register accessilibity tables (thanks @CTCaer).
+  + I believe this had no impact on official code, though it would have prevented some homebrew from interacting correctly with the MC0/MC1 registers.
++ An issue was fixed that could cause a deadlock when building multiple romfs images simultaneously (thanks @Ereza).
+  + This fixes support for certain mods, e.g. system language translations overriding content for both overlayDisp and qlaunch.
++ General system stability improvements to enhance the user's experience.
+## 1.9.3
++ Basic support was added for 20.3.0.
++ Compatibility was fixed for loading mods with KOTOR 2 (star wars).
++ General system stability improvements to enhance the user's experience.
+## 1.9.2
++ Basic support was added for 20.2.0.
++ USB 3.0 support force-enable was fixed for 20.1.0+.
++ General system stability improvements to enhance the user's experience.
+## 1.9.1
++ Basic support was added for 20.1.0.
++ General system stability improvements to enhance the user's experience.
 ## 1.9.0
 + Basic support was added for 20.0.0.
   + The console should boot and atmosphère should be fully functional. However, not all modules have been fully updated to reflect the latest changes.
