1.2.0 is Atmosphère’s fifty-seventh official release.
Please be sure to update fusee when upgrading to 1.2.0. fusee-primary no longer exists, and will not work any more.
Please note: Atmosphère 1.2.0 is currently in pre-release, and issues may be found that need to be fixed before full release.
- If any bugs are reported while Atmosphère is in pre-release, they will be fixed and the build will be updated.
- 1.2.0 will transition to release after a short amount of time has passed without pressing bug reports.
With thanks to the @switchbrew team, Atmosphère 1.2.0 is bundled with hbl 2.4.1, and hbmenu 3.4.1.
The following was changed since the last release:
boot was updated to reflect the latest official behavior for display/battery management.
- This should fix any issues that might result from running older releases on the OLED model, if you’re somehow in a position to do so.
- The « target firmware » system was changed to allow the bootloader to specify an approximation, rather than the true target firmware.
- Previously we expected compliant bootloaders to inspect SYSTEM:/ to determine the specific target firmware.
- Now, we only require an approximate version, with major version == true major version and approximate version <= true version.
- This greatly simplifies bootloader requirements, and correspondingly all code for accessing SYSTEM has been removed from fusee.
- This should result in a substantial speedup when booting emummc with fusee, as SYSTEM accesses were the most expensive thing done previously.
- This should resolve any inconsistency in firmware detection when booting via fusee vs hekate.
- This should also improve our compatibility with micro firmware releases, making it more likely that atmosphere « just works » if nothing important has changed.
- Dynamic resource limit determination logic was implemented in
pm to match latest official behavior.
- This greatly simplifies/makes consistent the resource limits on older firmwares, as well.
- An enormous amount of refactoring was performed under the hood, including:
- Please Note: If you are a developer who uses Atmosphere-libs, a number of changes here are breaking.
- Feel free to contact SciresM#524 for help updating your program.
- The OS namespace had many primitives implemented/made more accurate.
- Since mesosphere is now always-on, os::LightEvent (which required newer SVCs) is now globally usable (and used by stratosphere where relevant).
- Assertions are now true no-ops when building for release.
- Stratosphere is now built with -Wextra/-Werror.
- Most « common » logic in system module main.cpp files was moved into libstratosphere.
- Please Note: main.cpp files for prior atmosphere-libs will no longer work, for a really large number of reasons.
- A number of longstanding code style issues were corrected.
- Mesosphere now uses util::BitFlagSet for SVC permissions.
- Mesosphere now puts its relocation table inside .bss, which allows that memory to be reclaimed after relocations are performed.
- These changes save ~16KB of memory in the kernel, all said and done.
- A number of locations in stratosphere where memory could be saved were spotted and taken advantage of, leading to ~150-200KB of saved memory.
loader system module was refactored to better reflect official logic.
sf ipc server code was updated to only emit mitm/defer logic when that logic is actually required somewhere in process.
tipc ipc server code was updated to reflect changes to official logic made in 13.0.0.
- Many, many other minor changes, please talk to SciresM#524 or read the relevant commits if you want to know more.
- A number of minor issues were fixed, including:
- Mesosphere’s handling of SVC permissions on thread pin/unpin was updated to reflect official kernel behavior.
- util::CountTrailingZeroes() was fixed to calculate the correct value when used at compile-time.
- General system stability improvements to enhance the user’s experience.
