 # 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.
