This was tested using `https://github.com/node-dot-cpp/alloc-test` plus a few other by-hand tests.
It seems to work for the case we care about (sysmodules without thread cache-ing).
External users are advised to build with assertions on and contact SciresM if you find issues.
This is a lot of code to have gotten right in one go, and it was written mostly after midnight while sick, so there are probably un-noticed issues.

+ A bug was fixed that could cause owls to flicker under certain circumstances.
+ For those interested in technical details, in 10.0.0 kernelldr/kernel no longer set cpuactlr_el1, assuming that it was set correctly by the secure monitor.
+ However, exosphere did not set cpuactlr_el1. This meant that the register held the reset value going into boot.
+ This caused a variety of highly erratic symptoms, including causing basically any game to crash seemingly randomly.
+ A number of other major inaccuracies in exosphere were corrected.
+ General system stability improvements to enhance the user's experience.
## 0.11.0
+ Support was added for 10.0.0.
+ Exosphere has been updated to reflect the new key import semantics in 10.0.0.
+ kernel_ldr now implements physical ASLR for the kernel's backing pages.
+ Loader, NCM, and PM have been updated to reflect the changes Nintendo made in 10.0.0.
+ Creport was updated to use the new `pgl` service to terminate processes instead of `ns:dev`.
+ A reimplementation of the `erpt` (error reports) system module was added.
+ In previous versions of Atmosphere, a majority of error reports were prevented via a combination of custom creport, fatal, and stubbed eclct.
+ However, error reports were still generated via some system actions.
+ Most notably, any time the error applet appeared, an error report was generated.
+ By default, atmosphere disabled the *uploading* of error reports, but going online in OFW after an error report occurred in Atmosphere could lead to undesirable telemetry.
+ Atmosphere's `erpt` reimplementation allows the system to interact with existing error reports as expected.
+ However, all new error reports are instead saved to the sd card (`/atmosphere/erpt_reports`), and are not committed to the system savegame.
+ Users curious about what kind of telemetry is being prevented can view the reports as they're generated in there.
+ Reports are saved as msgpack (as this is what Nintendo uses).
+ Please note, not all telemetry is disabled. Play reports and System reports will continue to function unmodified.
+ With atmosphere's `erpt` implementation, homebrew can now use the native error applet to display errors without worrying about generating undesirable telemetry.
+ libstratosphere and libvapours received a number of improvements.
+ With thanks to @Adubbz for his work, the NCM namespace now has client code.
+ This lays the groundwork for first-class system update/downgrade homebrew support in the near future.
+ In particular, code implementing the os namespace is significantly more accurate.
+ In addition, Nintendo's allocators were implemented, allowing for identical memory efficiency versus Nintendo's implementations.
+ General system stability improvements to enhance the user's experience.
## 0.10.5
+ Changes were made to the way fs.mitm builds images when providing a layeredfs romfs.
+ Building romfs metadata previously had a memory cost of about ~4-5x the file table size.
+ This caused games that have particularly enormous file metadata tables (> 4 MB) to exhaust fs.mitm's 16 MB memory pool.
+ The code that creates romfs images was thus changed to be significantly more memory efficient, again.
+ Memory requirements have been lowered from ~4x file table size to ~2x file table size + 0.5 MB.
+ There is a slight speed penalty to this, but testing on Football Manager 2020 only took an extra ~1.5 seconds for the game to boot with many modded files.
+ This shouldn't be noticeable thanks to the async changes made in 0.10.2.
+ If you encounter a game that exhausts ams.mitm's memory (crashing it) when loading layeredfs mods, please contact SciresM.
+ Romfs building can be made even more memory efficient, but unless games show up with even more absurdly huge file tables it seems not worth the speed trade-off.
+ A bug was fixed that caused Atmosphere's fatal error context to not dump TLS for certain processes.
+ General system stability improvements to enhance the user's experience.
## 0.10.4
+ With major thanks to @Adubbz for his work, the NCM system module has now been re-implemented.
+ This was a major stepping stone towards the goal of having implementations everything in the Switch's package1/package2 firmware.
+ This also lays the groundwork for libstratosphere providing bindings for changing the installed version of the Switch's OS.
+ **Please Note**: The NCM implementation will initially be opt-in.
+ The Atmosphere team is confident in our NCM implementation (and we have tested it on every firmware version).
+ That said, this is our first system module that manages NAND savegames -- and caution is a habit.
+ We do not anticipate any issues that didn't come up in testing, so this is just our being particularly careful.
+ Users interested in opting in to using our implementation should set `stratosphere!ncm_enabled = 1` in BCT.ini.
+ In the unlikely event that any issues are encountered, please report them to @SciresM.
+ The NCM implementation will stop being opt-in in a future update, after thorough testing has been done in practice.
+ A bug was fixed in emummc that caused Nintendo path to be corrupted on 1.0.0.
+ This manifested as the emummc folder being created inside the virtual NAND instead of the SD card.
+ It's unlikely there are any negative consequences to this in practice.
+ If you want to be truly sure, you can re-clone sysmmc before updating a 1.0.0 emummc to latest firmware.
+ Stratosphere system modules now use new Nintendo-style FS bindings instead of stdio.
+ This saves a modest amount of memory due to leaner code, and greatly increases the accuracy of several components.
+ These bindings will make it easier for other system modules using libstratosphere to interact with the filesystem.
+ This also lays the groundwork for changes necessary to support per-emummc Atmosphere folders in a future update.
+ Atmosphere's fatal error context now dumps 0x100 of TLS.
+ This will make it much easier to fix bugs when an error report is dumped for whatever caused the crash.
+ General system stability improvements to enhance the user's experience.
## 0.10.3
+ Support was added for 9.2.0.
+ Support was added for redirecting manual html content for games.
+ This works like normal layeredfs, replacing content placed in `/atmosphere/contents/<program id>/manual_html/`.
+ This allows for game mods/translations to provide custom manual content, if they so choose.
+ A number of improvements were made to Atmosphere's memory usage, including:
+ `fatal` now uses STB instead of freetype for rendering.
+ This saves around 1 MB of memory, and makes our fatal substantially leaner than Nintendo's.
+ `sm` no longer wastes 2 MiB unnecessarily.
+ fusee/sept's sdmmc access now better matches official behavior.
+ This improves compatibility with some SD cards.
+ `ro` has been updated to reflect changes made in 9.1.0.
+ The temporary auto-migration added in 0.10.0 has been removed, since the transitionary period is well over.
+ General system stability improvements to enhance the user's experience.
## 0.10.2
+ hbl configuration was made more flexible.
+ Up to eight specific program ids can now be specified to have their own override keys.
