 # Changelog
+## 0.15.0
++ fusee-primary's panic display was updated to automatically identify and give suggestions to resolve many of the most common errors users encounter.
++ Having been tested as well as I can alone, `mesosphere` (atmosphère's reimplementation of the Nintendo Switch kernel) is now available for users interested in trying it.
+  + Beginning in this release and until it is stable and well-tested, atmosphère will distribute two zips.
+    + Users who wish to opt-in to mesosphere should download and extract the "cool kids" zip ("atmosphere-EXPERIMENTAL-").
+    + Users who do not wish to use mesosphere should continue using the normal zip ("atmosphere-").
+  + Users may detect whether mesosphere is active in system settings.
+    + When mesosphere is active, the system version string will display "M.15.0" rather than "0.15.0", and so on for future releases.
+    + Crash reports and the like will contain information on whether or not the user is using mesosphere, as well.
+  + There are "probably" no material user-facing benefits to using mesosphere at this time.
+    + Developers may be interested in the fact that mesosphere provides many newer SVC APIs even when on lower firmware versions.
+    + The primary benefit to using mesosphere is that any issues you may encounter and report to me will be fixed.
+      + All users who choose to opt in to using mesosphere have my deepest gratitude.
+  + **Note:** If using hekate instead of fusee-primary, you will have to wait for the next hekate release for mesosphere to function, as hekate's support has not yet been included in an official release build.
+    + This will be updated in the release notes when hekate provides a new release.
+  + As mentioned in previous release notes, when mesosphere is stable and well-tested, it will be enabled by default and atmosphère's version will transition to 1.0.0.
++ Having been tested sufficiently over the last half-year, Atmosphere's NCM implementation is now opt-out, rather than opt in.
+  + In the unlikely event that any issues are encountered, please report them to @SciresM.
+  + Users interested in opting out of using our implementation should set `stratosphere!disable_ncm = 1` in BCT.ini.
+  + The NCM implementation will stop being opt-out in a future update, probably around the same time that mesosphere becomes opt-out instead of opt-in.
++ Several bugs were fixed, including:
+  + Loader now sets HBL's thread priority to a higher value when loading it in applet mode.
+    + This fixes an extremely-slow launch ("hang") when using applet-HBL with certain games that do not suspend while inactive (e.g. Super Mario Sunshine).
+  + set.mitm now caches user language configuration much more heavily.
+    + This severely reduces lag in certain games which misuse the "nn::oe::GetDesiredLanguage()" API.
+  + A bug was fixed that could cause erpt to fatal when loading an official save file that had error report attachments in it.
++ General system stability improvements to enhance the user's experience.
+## 0.14.4
++ Several bugs were fixed involving the official jit sysmodule added in 10.0.0.
+  + A Process handle leak was fixed when JitPlugin NRRs were registered with the `ro` sysmodule.
+    + This prevented processes using jit from being able to exit, causing a full system freeze.
+  + The `sm` atmosphere extension to not unregister services when the server's connection is closed was special-case disabled for `jit:u`.
+    + This extension is normally desirable in order to allow more concurrent processes to exist (as only 0x40 sm connections may ever be concurrently open), but official jit sysmodule relies on the behavior.
+    + This would cause crashes on attempts to launch a program using jit services more than once per reboot.
++ General system stability improvements to enhance the user's experience.
+## 0.14.3
++ Support was added for 10.2.0.
++ General system stability improvements to enhance the user's experience.
+## 0.14.2
++ A bug was fixed that could cause a deadlock when installing mitm services.
+  + Fixing this required a breaking change to the client behavior when installing a mitm service, and so custom sysmodules which use mitm will need to be re-compiled to function properly.
++ A bug was fixed that caused atmosphere sysmodules to respond incorrectly when receiving invalid messages.
++ A bug was fixed that caused fatal auto-reboot timing to work improperly.
++ Support was added to fusee for loading binaries for `mesosphere`, atmosphère's reimplementation of the Nintendo Switch kernel.
+  + 0.14.2 does not include mesosphere, but those who are especially interested can build and test mesosphere themselves.
+  + In the future, to enable a sufficient testing period Atmosphère releases will distribute two zips for some time.
+    + One zip will use mesosphere, and the other will not.
+    + This will allow users who are interested to opt-in to mesosphere usage before it has been tested to be stable.
+  + When mesosphere is stable and well-tested, it will be enabled by default and Atmosphère's version will transition to 1.0.0.
++ General system stability improvements to enhance the user's experience.
+## 0.14.1
++ An issue was fixed in 0.14.0 that would cause a black screen on boot when the INI1's size was not aligned to 8 bytes.
++ General system stability improvements to enhance the user's experience.
+## 0.14.0
++ An API (`ams:su`) was added to allow homebrew to safely install system upgrades or downgrades.
+  + This is a re-implementation of the logic that `ns` uses to install gamecard system updates.
+  + Nintendo (and now atmosphère) uses an installation process that can recover no matter where a failure occurs, which should significantly improve the safety of custom system update installation.
++ Support was added to `exosphère` for running on Mariko hardware.
+  + **Please note**: Atmosphère still does not support Mariko, and should not be run on Mariko yet.
+    + Certain stratosphere components do not handle mariko-specific logic fully correctly yet, and may initialize or interact with hardware incorrectly.
+    + This will be fixed and support will be added over the remainder of the Summer.
++ A homebrew application (`daybreak`) was added that uses the system updater API (with thanks to @Adubbz for both design and implementation).
+  + `daybreak` is included with atmosphère, and functions as a safer/more accurate equivalent to e.g. ChoiDujourNX.
+  + Upgrades/downgrades can be installed from a folder containing the update NCAs on the SD card.
+  + Because the update logic functions identically to Nintendo's, `daybreak` will be safe to use on Mariko when the rest of atmosphère has support.
+  + **Please note**: Daybreak requires that meta (.cnmt) NCAs have the correct extension `.cnmt.nca`.
+    + This is because gamecard system update logic uses extension to determine whether to mount the content.
+    + [Several](https://gist.github.com/HookedBehemoth/df36b5970e1c5b1b512ec7bdd9043c6e) [scripts](https://gist.github.com/antiKk/279966c27fdfd9c7fe63b4ae410f89c4) have been made by community members to automatically rename folders with incorrect extensions.
++ A bug was fixed that would cause file-based emummc to throw an error (showing a hexdump) on boot.
+  + Major thanks to @hexkyz for tracking down and resolving this.
++ A number of minor issues were resolved, including:
+  + fusee now prints information to the screen when an error occurs, instead of getting stuck trying to initialize the display.
+  + A race condition in Horizon was worked around that could prevent boot under certain circumstances.
+  + A bug was fixed that would cause atmosphère modules to open ten copies of certain filesystems instead of one.
+    + This could cause object exhaustion under certain circumstances.
++ For those interested in atmosphère's future development plans, the project's [roadmap](https://github.com/Atmosphere-NX/Atmosphere/blob/ac9832c5ce7be5832f6d29f6564a9c03e7efd22f/docs/roadmap.md) was updated.
++ General system stability improvements to enhance the user's experience.

 ## ams-on-mariko
-* **Description**: Atmosphere cannot run as-is on Mariko hardware. A large number of changes are needed in many components. Although exosphere's rewrite laid most groundwork on the secure monitor side, there is still work to do there -- and additional work is needed on the bootloader and stratosphere sides as well. Mariko support will also require further design thought; atmosphere's debugging design heavily relies on reboot-to-payload and (more generally) the ability to perform warmboot bootrom hax at will. This is not possible on Mariko, and will require a new design/software support for whatever solution is chosen.

It is written in C, and in a style very different from the rest of atmosphère's code. In addition, exosphère was written to conform to constraints that no longer apply in an environment where it is not launched from the web browser, and where using a custom firmware image to orchestrate wake-from-sleep is possible. exosphère currently uses all but 1 KB of the space available to it, putting it at risk of breaking as future firmware updates are supported. A re-write will solve these issues.
