 Atmosphère consists of multiple components, each of which replaces/modifies a different component of the system:
 
 * Fusée: First-stage Loader, responsible for loading and validating stage 2 (custom TrustZone) plus package2 (Kernel/FIRM sysmodules), and patching them as needed. This replaces all functionality normally in Package1loader/NX Bootloader.
-    * Sept: Payload used to enable support for runtime key derivation on 7.0.0.
 * Exosphère: Customized TrustZone, to run a customized Secure Monitor
 * Thermosphère: EL2 EmuNAND support, i.e. backing up and using virtualized/redirected NAND images
 * Stratosphère: Custom Sysmodule(s), both Rosalina style to extend the kernel/provide new features, and of the loader reimplementation style to hook important system actions

 # Changelog
+## 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.
+    + There shouldn't be anything user visible resulting from this, but it will be addressed in a future atmosphère update.
+    + The same action item from 18.0.0 remains, and I believe in my heart of hearts that it will be addressed eventually. Someone has told me they're working on it.
+    + There aren't (to my knowledge) outstanding 19.0.0 items any more.
+  + **Please note**: As a result of changes made to nintendo's software in 20.0.0, there is roughly 10MB less memory available for custom system modules.
+    + We can only steal a maximum of 14MB from the applet pool, down from 40MB.
+    + To compensate for this, `ams.mitm`'s heap usage has been reduced by 20MB.
+      + To facilitate this, a new helper module (`memlet`) was added, so that memory may be temporarily stolen during the romfs building process.
+      + Hopefully, this results in relatively little breakage, however it is possible that user mods which replace extremely large numbers of files in The Legend of Zelda: Tears of the Kingdom may no longer function.
+        + 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. However, some issues may be impossible to fix.
+        + I apologize sincerely if the issue is impossible to resolve, but I have been forced unavoidably to make compromises here, and I think this is the best balance to be struck.
+  + `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.
+  + `ncm` was partially updated to reflect the latest official behavior.
+  + `erpt` was updated to reflect the latest official behavior.
++ Atmosphère was updated to use GCC 15/newlib (latest devkitA64/devkitARM releases).
++ A number of improvements were made to the dmnt cheat engine.
+  + New instructions were added, and instructions were updated for improved/new functionality.
+  + Please see the documents for details -- thanks @tomvita!
++ General system stability improvements to enhance the user's experience.
 ## 1.8.0
 + Basic support was added for 19.0.0.
   + The console should boot and atmosphère should be fully functional. However, not all modules have been fully updated to reflect the latest changes.
