 # Changelog
+## 0.9.3
++ Thanks to hexkyz, fusee's boot sequence has been greatly optimized.
+  + Memory training is now managed by a separate binary (`fusee-mtc`, loaded by fusee-primary before fusee-secondary).
+  + Unnecessarily long splash screen display times were reduced.
+  + The end result is that Atmosphere now boots *significantly* faster. :)
+  + **Note:** This means fusee-primary must be updated for Atmosphere to boot successfully.
++ The version string was adjusted, and now informs users whether or not they are using emummc.
++ Atmosphere now automatically backs up the user's BIS keys on boot.
+  + This should prevent a user from corrupting nand without access to a copy of the keys needed to fix it.
+    + This is especially relevant on ipatched units, where the RCM vulnerability is not an option for addressing bricks.
++ The `pm` system module was rewritten as part of Stratosphere's ongoing refactor.
+  + Support was added for forward-declaring a mitm'd service before a custom user sysmodule is launched.
+    + This should help resolve dependency issues with service registration times.
+  + SM is now informed of every process's title id, including built-in system modules.
++ The `creport` system module was rewritten as part of Stratosphere's ongoing refactor.
+  + creport now dumps up to 0x100 of stack from each thread in the target process.
+  + A few bugs were fixed, including one that caused creport to incorrectly dump process dying messages.
++ Defaults were added to `system_settings.ini` for controlling hbloader's memory usage in applet mode.
+  + These defaults reserve enough memory so that homebrew can launch swkbd while in applet mode.
++ The `fatal` system module was rewritten as part of Stratosphere's ongoing refactor.
+  + Incorrect display output ("2000-0000") has been fixed. Fatal will now correctly show 2162-0002 when this occurs.
+  + A longstanding bug in how fatal manages the displays has been fixed, and official display init behavior is now matched precisely.
++ General system stability improvements to enhance the user's experience.
 ## 0.9.2
 + A number of emummc bugfixes were added (all thanks to @m4xw's hard work). The following is a summary of emummc changes:
   + Support for file-based emummc instances was fixed.
