# Changelog # 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 ## 1.11.2
