# Changelog
## 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.
+ This allows designating both the album applet and a specific game as hbl by default as desired.
+ Configuration targeting a specific program is now mutually exclusive with override-any-app for that program.
+ This fixes unintuitive behavior when override key differed for an application specific program.
+ Loader's external content fileystem support was fixed (thanks @misson20000!).
+ KernelLdr was reimplemented.
+ This is the first step towards developing mesosphere, Atmosphere's planned reimplementation of the Switch's Kernel.
+ The typical user won't notice anything different, as there are no extensions, but a lot of groundwork was laid for future development.
+ Improvements were made to the way Atmosphere's buildsystem detects source code files.
+ This significantly reduces compilation time (saving >30 seconds) on the machine that builds official releases.
+ Certain device code was cleaned up and made more correct in fusee/sept/exosphere (thanks @hexkyz!).
+ A number of changes were made to the way fs.mitm builds images when providing a layeredfs romfs.
+ Some games (Resident Evil 6, Football Manager 2020 Touch, possibly others) have enormous numbers of files.
+ Attempting to create a layeredfs mod for these games actually caused fs.mitm to run out of memory, causing a fatal error.
+ The code that creates these images was changed to be significantly more memory efficient.
+ However, these changes also cause a significant slowdown in the romfs building code (~2-5x).
+ This introduced a noticeable stutter when launching a game, because the UI thread would block on the romfs creation.
+ To solve this, fs.mitm now lazily initializes the image in a background thread.
+ This fixes stutter issues, however some games may be slightly slower (~1-2s in the worst cases) to transition from the "loading" GIF to gameplay now.
+ Please note: the slowdown is not noticeable in the common case where games don't have tons of files (typical is ~0.1-0.2 seconds).
+ Once the image has been built, there is no further speed penalty at runtime -- only when the game is launched.
+ A number of other bugs were fixed, including:
+ Several minor logic inversions that could have caused fatal errors when modding games.
+ Atmosphere's new-ipc code did not handle "automatic" recvlist buffers correctly, so some non-libnx homebrew could crash.
+ fs.mitm now correctly mitms sdb, which makes redirection of certain system data archives work again.
+ In 0.10.0/0.10.1, changing the system font/language did not work correctly due to this.
+ A bug was fixed in process cleanup that caused the system to hang on < 5.0.0.
+ The temporary hid-mitm added in Atmosphere 0.9.0 was disabled by default.
+ Please ensure your homebrew is updated.
+ For now, users may re-enable this mitm by use of a custom setting (`atmosphere!enable_deprecated_hid_mitm`) to ease the transition process some.
+ Please note: support for this setting may be removed to save memory in a future atmosphere release.
+ General system stability improvements to enhance the user's experience.
## 0.10.1
+ A bug was fixed that caused memory reallocation to the system pool to work improperly on firmware 5.0.0 and above.
+ Atmosphere was always trying to deallocate memory away from the applet pool and towards the system pool.
