You'll need to install the following packages via (dkp-)pacman: switch-dev switch-freetype devkitARM devkitarm-rules
 
-Once you have finished installing devkitARM and devkitA64, simply clone the Atmosphère repo, change to it and run `make`.
+sept requires you have python installed with the pycrypto and pycryptodome PyPi packages (pip install pycrypto pycryptodome). You may also want to install the zip package from your package manager of choice to support the `make dist` recipe.

 # Changelog
+## 0.8.7
++ A few bugs were fixed that could cause fatal to fail to show an error under certain circumstances.
++ A bug was fixed that caused an error when launching certain games (e.g. Hellblade: Senua's Sacrifice).
+  + Loader had support added in ams-0.8.4 for a new (7.0.0+) flag bit in NPDMs during process creation, but forgot to allow this bit to be set when validating the NPDM.
++ dmnt's cheat virtual machine received new instructions.
+  + These allow for saving, restoring, or clearing registers to a secondary bank, effectively doubling the number of values that can be stored.
++ SHA256 code has been swapped from linux code to libnx's new hw-accelerated cryptography API.
++ Extensions were added to smcGetInfo:
+  + A ConfigItem was added to detect whether the current unit has the RCM bug patched.
+  + A ConfigItem was added to retrieve the current Atmosphère build hash.
++ Exosphère now tells the kernel to enable user-mode exception handlers, which should allow for better crash reporting/detection from Atmosphère's modules in the future..
++ Opt-in support was added for redirecting game save files to directories on the SD card.
+  + Please note, this feature is **experimental**, and may cause problems. Please use at your own risk (and back up your saves before enabling it), as it still needs testing.
+  + This can be enabled by setting `atmosphere!fsmitm_redirect_saves_to_sd` to 1 in `system_settings.ini`.
++ General system stability improvements to enhance the user's experience.
+## 0.8.6
++ A number of bugs were fixed, including:
+  + A case of inverted logic was fixed in fs.mitm which prevented the flags system from working correctly.
+  + Time service access was corrected in both creport/fatal.
+    + This fixes the timestamps used in fatal/crash report filenames.
+  + A coherency issue was fixed in exosphère's Security Engine driver.
+    + This fixes some instability issues encountered when overclocking the CPU.
+  + Loader now unmaps NROs correctly, when ldr:ro is used.
+    + This fixes a crash when repeatedly launching the web applet on < 3.0.0.
+  + Usage of hidKeysDown was corrected to hidKeysHeld in several modules.
+    + This fixes a rare issue where keypresses may have been incorrectly detected.
+  + An issue with code filesystem unmounting was fixed in loader.
+    + This issue could occasionally cause a fatal error 0x1015 to be thrown on boot.
+  + Two bugs were fixed in the implementations of dmnt's cheat virtual machine.
+    + These could cause cheats to work incorrectly under certain circumstances.
+  + PM now uses a static buffer instead of a dynamically allocated one during process launch.
+    + This fixes a memory exhaustion problem when building with gcc 8.3.0.
+  + A workaround for a deadlock bug in Horizon's kernel on >= 6.0.0 was added in dmnt.
+    + This prevents a system hang when booting certain titles with cheats enabled (ex: Mario Kart 8 Deluxe).
+  + set.mitm now reads the system firmware version directly from the system version archive, instead of calling into set:sys.
+    + This fixes compatibility with 1.0.0, which now successfully boots again.
++ dmnt's cheat virtual machine had some instruction set changes.
+  + A new opcode was added for beginning conditional blocks based on register contents.
+  + More addressing modes were added to the StoreRegisterToAddress opcode.
+  + These should allow for more complex cheats to be implemented.
++ A new system for saving the state of cheat toggles between game boots was added.
+  + Toggles are now saved to `atmosphere/titles/<title id>/cheats/toggles.txt` when either toggles were successfully loaded from that file or the system setting `atmosphere!dmnt_always_save_cheat_toggles` is non-zero.
+  + This removes the need for manually setting cheats from all-on or all-off to the desired state on each game boot.
++ The default behavior for loader's HBL support was changed.
+  + Instead of launching HBL when album is launched without R held, loader now launches HBL when album or any game is launched with R held.
+  + Loader will now override any app in addition to a specific title id when `hbl_config!override_any_app` is true in `loader.ini`.
+    + Accordingly, the `hbl_config!title_id=app` setting was deprecated. Support will be removed in Atmosphère 0.9.0.
++ First-class support was added to loader and fs.mitm for enabling homebrew to launch web applets.
+  + Loader will now cause the "HtmlDocument" NCA path to resolve for whatever title HBL is taking over, even if it would not normally do so.
+  + fs.mitm will also now cause requests to mount the HtmlDocument content for HBL's title to open the `sdmc:/atmosphere/hbl_html` folder.
+    + By default, this just contains a URL whitelist.
++ General system stability improvements to enhance the user's experience.
 ## 0.8.5
 + Support was added for overriding content on a per-title basis, separate from HBL override.
   + This allows for using mods on the same title that one uses to launch HBL.

 Atmosphère can use the loader module in order to turn any game on your Switch's home menu into a launchpoint for the Homebrew Menu, rather than launching it through the album applet. This allows one to launch the Homebrew Menu with access to the ~3.2GB of RAM that the Switch reserves for games and applications, as opposed to the 442MB of RAM we are limited to when launching the Homebrew Menu from the album. This also means that it is no longer necessary to install homebrew as `.nsp` files on your Switch so long as you are using this method, as the only reason to do so is to allow the homebrew to access all of the Switch's available memory.
 
-In order to setup this method you will need the latest release of [hbmenu](https://github.com/switchbrew/nx-hbmenu/releases), and the latest release of [hbloader](https://github.com/switchbrew/nx-hbloader/releases). Place `hbmenu.nro` on the root of your Switch's SD Card, and place `hbl.nsp` in the atmosphere folder. From there, simply configure `loader.ini` in the atmosphere folder by replacing the Title ID in the ini (title_id in the [hbl_config] section) (it is the Title ID for the album by default) with the Title ID of whatever game you wish to use to launch the Homebrew Menu. A list of Title IDs for Switch Games can be found [here](https://switchbrew.org/wiki/Title_list/Games). Afterwards you may reinsert your SD Card into your Switch and boot into Atmosphère as you normally would. You should now be able to boot into the Homebrew Menu by launching your designated game of choice.
+In order to setup this method you will need the latest release of [hbmenu](https://github.com/switchbrew/nx-hbmenu/releases), and the latest release of [hbloader](https://github.com/switchbrew/nx-hbloader/releases). Place `hbmenu.nro` on the root of your Switch's SD Card, and place `hbl.nsp` in the atmosphere folder. From there, simply launch any title while holding the button specified in `loader.ini`.
+
+In addition, loader has extensions to enable homebrew to launch web applets. This normally requires the application launching the applet have HTML Manual content inside an installed NCA; Atmosphère's loader will automatically ensure that the commands used to check this succeed, and will (in tandem with `fs.mitm`) redirect the relevant filesystem to the `sdmc:/atmosphere/hbl_html/` subdirectory.
 
 ### Button Overrides
 
-By default `loader.ini` is configured to launch the Homebrew Menu when launching the game normally, and launching the game when selecting the game while holding down R. If you wish to change this, you can modify the override_key section of `loader.ini`. Placing an exclamation point in front of whatever button you wish to use will make it so that you will only launch the actual game while holding down that button, otherwise you will go into the Homebrew Menu. Removing the exclamation point will reverse this, meaning that you will boot into the Homebrew Menu only while holding down the assigned button when launching the game.
+By default `loader.ini` is configured to launch the Homebrew Menu when launching any game while holding down the override key (defaults to R). If you wish to change this, you can modify the override_key section of `loader.ini`. Alternatively, if you would like to only allow hbmenu on a specific app, configure `loader.ini` in the atmosphere folder by replacing the Title ID in the ini (title_id in the [hbl_config] section, it is the Title ID for the album by default) with the Title ID of whatever game you wish to use to launch the Homebrew Menu, and set override_any_app to false. A list of Title IDs for Switch Games can be found [here](https://switchbrew.org/wiki/Title_list/Games).
 
-For example, `override_key=!R` will run the game only while holding down R when launching it, otherwise it will boot into the Homebrew Menu. `override_key=R` will only boot into the Homebrew Menu while holding down R when launching the game, otherwise it will launch the game as normal.
+To invert the behaviour of the override key, place an exclamation point in front of whatever button you wish to use. It will launch the actual game while holding down that button, instead of going into the Homebrew Menu. For example, `override_key=!R` will run the game only while holding down R when launching it, otherwise it will boot into the Homebrew Menu. Afterwards you may reinsert your SD Card into your Switch and boot into Atmosphère as you normally would. You should now be able to boot into the Homebrew Menu by launching your designated title of choice.

+to "normal" skips these behaviours.
