 # Changelog
+## 0.19.5
++ Support was added for 12.1.0.
++ LayeredFS support was added for OpenDataStorageWithProgramIndex commands.
+  + Certain games using newer (7.0.0+ APIs) which include multiple programs under a single title previously could not be modified.
+  + These are now supported as normal, and LayeredFS should have 100% compatibility again.
++ A number of minor issues were fixed, including:
+  + The Reboot to Payload NRO was updated to allow the OS to save state prior to rebooting (thanks @AuroraWright)!
+  + An issue was fixed that could cause dns.mitm to fail when games requested resolution of an empty string.
+  + An issue was fixed that caused a memory leak in the erpt system module.
+    + This would eventually cause a system crash after ~540 reports were generated without rebooting.
++ A number of minor improvements were made to improve mesosphere's accuracy.
++ General system stability improvements to enhance the user's experience.
+## 0.19.4
++ Support was added for 12.0.3.
++ A number of minor issues were fixed, including:
+  + An issue was fixed that could cause heap memory corruption when allocation was highly contended.
+  + An issue was fixed that could cause sleep to fail under certain conditions.
+  + An issue was fixed that could cause a scheduler slow path to be taken more often than necessary.
++ General system stability improvements to enhance the user's experience.
+## 0.19.3
++ Support was added for 12.0.2.
++ A number of minor issues were fixed, including:
+  + An issue was fixed in dns.mitm that caused a crash when games attempted to resolve the IP address of nullptr.
+  + An issue was fixed in erpt that would cause an abort when booting without having ever booted stock previously.
+  + An issue was fixed in (file-based) emummc that caused an error on system format/downloading certain games.
++ General system stability improvements to enhance the user's experience.
+## 0.19.2
++ Atmosphère's components were further updated to reflect latest official behaviors as of 12.0.0.
+  + Notably, `erpt` was updated to implement the new forced shutdown detection feature.
+    + When a forced-shutdown occurs, an erpt_report will be generated and saved to the SD card on the next boot.
++ Atmosphere-libs was updated to use GCC 11 (latest devkitA64/devkitARM releases).
+  + Initial inspections show mild-to-moderate optimizer improvements in several important places (kernel is 0x3000 smaller).
+  + General system stability improvements to enhance the user's experience.
++ A number of minor issues were fixed, including:
+  + A bug was fixed that caused a black screen when attempting to boot firmware versions 2.0.0-4.1.0.
+  + A bug was fixed that caused sm to abort when at the session limit, rather than returning error codes.
+  + A bug was fixed that allowed for resource exhaustion on 12.0.0, under certain circumstances.
++ Several issues were fixed, and usability and stability were improved.
+## 0.19.1
++ An issue was fixed that caused a fatal error when using official `migration` services to transfer data between consoles.
++ An issue was fixed in `ncm` that caused an error when the OS tried to enumerate installed SD card content.
++ Several issues were fixed, and usability and stability were improved.
+## 0.19.0
++ Support was added for 12.0.0.
+  + `mesosphère` was updated to reflect the latest official kernel behavior.
+  + `sm`, `boot2`, `pgl` were updated to reflect the latest official behaviors.
+    + **Please Note**: 12.0.0 added a new protocol for IPC ("tipc"), which has been freshly reimplemented in its entirety.
+      + It is possible there may be as of yet unfound issues; if there are, please send the appropriate crash reports to SciresM (SciresM#0524 on discord).
+      + Homebrew which uses atmosphere extensions (including the mitm API) will need to be re-compiled in order to function on 0.19.0.
+        + I apologize for this, but it's unavoidable for technical reasons. If you're affected by this and mad about it, please contact SciresM to complain.
+  + `erpt` was partially updated to reflect the latest official behaviors.
+    + New features were added to erpt to track the activity of running applets, and to detect when a forced shutdown occurs.
+    + These behaviors have been temporarily stubbed, as they are not necessary for 12.0.0 to run (and their outputs won't be saved anywhere).
+    + A future atmosphère update will implement these behaviors, in the interest of reflecting official logic as faithfully as we can.
++ Atmosphère no longer uses the /contents/ folder for its own programs.
+  + Atmosphère's system modules are now bundled together in the single file "stratosphere.romfs".
+    + For those working on developing for atmosphère, executables inside the /contents/ directory will be preferred to those in "stratosphere.romfs".
+  + **Please Note**: In order to facilitate this change (and the desired behavior), the first time you boot after extracting a release zip, atmosphère system modules inside /contents/ will be deleted.
+    + This will have no impact on user programs (it only removes programs with specific program ids).
++ Improvements were made to mesosphere, including:
+  + An extension InfoType was added for getting the current process handle, without having to spawn a thread and do IPC with oneself.
+  + An issue was fixed in SvcSetDebugThreadContext.
+  + An issue was fixed when doing IPC with user buffers.
++ Support was fixed for toggling the custom setting `usb!usb30_force_enabled` on 9.0.0+.
+  + This was broken by Nintendo's introducing a dependency that made USB a requirement to launch before custom settings are parsed.
+  + Since the fix, you can now toggle the setting (as you could prior to atmosphère 0.9.4), and it will work as expected.
+  + **Please Note**: Enabling USB 3.0 often severely impacts wireless communications.
+    + Because of this, the setting will default to off. If you experience issues with it enabled, consider disabling it.
++ A warning was added to daybreak when resetting the console to factory settings.
++ Substantial work was completed towards atmosphere's upcoming implementation of the host target connection protocol.
+  + Once completed, users will be able to interact with a Switch running atmosphère via a PC application ("Starlink") currently under development.
+    + Planned eventual features for connected consoles include a gdbstub, interacting with memory (for cheat development), streaming gameplay audio and video, and accessing the Switch's SD card filesystem.
+    + Switch homebrew will also have access to a (configurable and sandboxed) filesystem on the host PC, while connected.
+  + Towards this end, the following was accomplished:
+    + The "htc" system module was reimplemented completely.
+    + The system module which provides remote access to the SD card was reimplemented completely.
+  + This is currently the active focus of atmosphère's development.
+  + **Please Note**: Support is not yet completed, and users are disadvised from interacting with the related settings for the time being, unless they particularly know what they're doing.
++ A number of minor issues were fixed, including:
+  + A bug was fixed in `dmnt` that could cause a fatal when launching certain games with cheats active.
+  + An issue was fixed that could cause an abort in `sm` when using a large number of custom system modules.
+  + An issue was fixed that prevented launching gamecards on 1.0.0.
+  + Minor issues were fixed in the cheat virtual machine's behavior.
++ Several issues were fixed, and usability and stability were improved.
+## 0.18.1
++ A number of minor issues were fixed, including:
+  + The new `dns.mitm` module added in 0.18.0 no longer fatal errors when receiving port=nullptr.
+    + This fixes youtube ad-blocking, and possibly other usecases.
+  + A bug was fixed that caused ams.mitm to incorrectly cache data storages.
+    + This potentially broke DLC when using romfs mods, and could have caused other issues (e.g. with custom themes, and maybe other cases).
+  + A bug was fixed in power state control module registration.
+    + This might fix a weird edge case with system module dependencies on sleep/wake, but probably nobody should notice any differences.
+  + A bug was fixed where mesosphere sometimes treated virtual core IDs as though they were physical core IDs.
+    + This had zero impact, because for Switch virtual core == physical core, but it could have affected future platforms if it had remained unresolved.
++ Several issues were fixed, and usability and stability were improved.
+## 0.18.0
++ A new mitm module was added (`dns.mitm`).
+  + This provides a highly configurable mechanism for redirecting DNS resolution requests.
+  + By default atmosphère redirects resolution requests for official telemetry servers to a loopback address.
+  + Documentation on how to configure `dns.mitm` to meet your more specific needs may be found [here](https://github.com/Atmosphere-NX/Atmosphere/blob/master/docs/features/dns_mitm.md).
++ The service framework API (`sf`) was refactored to be more accurate to official logic and greatly reduce memory requirements.
+  + The comparison of atmosphère module memory usage versus Nintendo's found [here](https://github.com/Atmosphere-NX/Atmosphere/wiki/Memory-Comparisons) was updated to reflect this.
+  + **Please Note**: If you are a developer using the libstratosphere service APIs, some updating may be required. Contact SciresM#0524 on discord for assistance if required.
++ A number of deprecations were removed, following a general codebase cleanup:
+  + The `sm` extension to not unregister services on connection close was superseded by official opt-in logic in 11.0.0, and has been removed in favor of official logic.
+    + This should have zero impact on users.
+  + The temporary `hid-mitm` added in 0.9.0 has finally been removed, following over a year of deprecation.
+    + There shouldn't be any homebrew in use still affected by this, but the situation will be monitored.
+    + If this is somehow still a real issue, an unaffiliated hid mitm sysmodule providing the same functionality can be created and released, separate from atmosphère itself.
++ Several issues were fixed, and usability and stability were improved.
+## 0.17.1
++ A number of atmosphère's modules were using more memory than their Nintendo equivalent's in 0.17.0; a number of code generatio tweaks have been applied to fix this across the board.
+  + A detailed comparison of atmosphère module memory usage versus Nintendo's was made and can be found [here](https://github.com/Atmosphere-NX/Atmosphere/wiki/Memory-Comparisons).
++ Several minor bugs were fixed, including:
+  + A bug was fixed in mesosphère that caused games which attempt to map more memory than the Switch has to fail.
+    + This affected "Piczle Lines DX 500 More Puzzles!", and possibly other games.
+  + Enabling configuration to "blank" PRODINFO no longer causes a hang on Mariko devices (or any devices with newer format).
++ Several issues were fixed, and usability and stability were improved.
+## 0.17.0
++ fusee was heavily rewritten in order to add support for Mariko hardware.
+  + **Please Note**: Mariko hardware currently has no (and may not ever have any) software exploits; fusee works when loaded from bootloader context with the right keys in the security engine. No means of getting the system into this state is provided.
++ An issue was fixed in the way shutdown was performed on Erista hardware.
+  + This fixes an issue that caused OFW to black screen on boot after power off from atmosphere without first doing a reboot.
+  + This also substantially improves power drain when the system is shut off; consoles powered off from Atmosphere should now drain battery at the same reduced rate as original firmware.
++ A number of minor changes were made, including:
+  + A number of inconsistencies in the build system were fixed.
+    + For those building atmosphère at home, the `boot` sysmodule will no longer rebuild every time make is invoked.
+    + This substantially improves build times during development iteration.
+  + `sm` was updated to more accurately reflect how official code manages request deferral.
+  + `mesosphère` was updated to more accurately reflect official kernel management of the trace buffer.
+  + `mesosphère` was updated to improve kernel loader's logic by taking advantage of the assumption that we only boot our kernel, not Nintendo's.
++ As it has been a few months with zero reported issues, `mesosphère` is now opt-out.
+    + Users who wish to begin using or continue using mesosphere should use the standard/cool kids zip ("atmosphere-").
+    + Users who wish to opt-out of mesosphere should download and extract the opt-out zip ("atmosphere-WITHOUT_MESOSPHERE-").
++ Several issues were fixed, and usability and stability were improved.
+## 0.16.2
++ Atmosphère release zips no longer bundle BCT.ini, instead relying on defaults in code.
+  + This means atmosphere updates should no longer overwrite any user configuration at all.
+  + If you wish to modify BCT.ini config, copy the template from /config_templates/ as with other configuration.
++ `pgl` and `creport` were further updated to reflect differences in official behavior in 11.0.0.
++ An issue was fixed that caused creport to be launched multiple times on process crash.
+  + This fixes the "duplicate reports" issue that sometimes plagued people.
++ A new system setting (`atmosphere!enable_am_debug_mode`) configuring am to use debug mode.
+  + If you are not a developer or don't see a clear use for this, leave it configured to the default (off).
++ Reboot to payload NRO was updated to fix support with certain payloads.
++ Support was fixed for atmosphere's extension to support homebrew use of new (8.0.0+) kernel mappings.
+  + In particular, when running tracing debug builds of `mesosphère`, hbloader now has access to the kernel trace buffer.
++ Several issues were fixed, and usability and stability were improved.
+## 0.16.1
++ Support was added for 11.0.1.
+  + `mesosphère` was updated to reflect the latest official kernel behavior.
+    + A new svc::InfoType added in 11.0.0 was implemented (it wasn't discovered before 0.16.0 released).
+    + The new Control Flow Integrity (CFI) logic added in 11.0.0 kernel was implemented.
++ `fs` logic was refactored and cleaned up to reflect some newer sysmodule behavioral and structural changes.
++ `exosphère` was updated to allow dynamic control of what uart port is used for logging.
+  + This can be controlled by editing the `log_port`, `log_baud_rate`, and `log_inverted` fields in `exosphere.ini`.
++ `mesosphère` was updated to improve debugging capabilities.
+  + This is still a work in progress, but developers may be interested.
++ A bug was fixed that caused `fatal` to fatal error if the fatal process was already being debugged.
++ Several issues were fixed, and usability and stability were improved.
+## 0.16.0
++ Support was added for 11.0.0.
+  + `exosphère` was updated to reflect the latest official secure monitor behavior.
+  + `mesosphère` was updated to reflect the latest official kernel behavior.
+  + `loader`, `sm`, `boot`, `pgl` were updated to reflect the latest official behaviors.
+    + **Please Note**: 11.0.0 implements an opt-in version of the atmosphère `sm` extension that allows for closing session without unregistering services.
+      + Correspondingly, the extension will be deprecated in favor of the new official opt-in command. In 0.17.0, it will be removed entirely.
+      + If your custom system module relies on this extension (however unlikely that seems to me), please update it accordingly.
+  + `erpt` was partially updated to provide compatibility with 11.0.0.
+    + The latest firmware attaches additional fields and context information to logs.
+    + A future atmosphère update will implement this logic, so that users who are interested can also get the new information when examining their logs.
+  + **Please Note**: 11.0.0 introduced breaking changes to the `usb` system module's `usb:ds` API.
+    + Homebrew which uses the `usb:ds` service should rebuild with the latest libnx version to support running on 11.0.0.
++ The `boot` system module was rewritten to reflect the huge driver changes introduced in 8.0.0.
+  + This includes a number of improvements to both logo display and battery management logic.
++ Support was added for configuring the address space width for `hbl`.
+  + The `hbl_config!override_address_space_(#)` and `hbl_config!override_any_app_address_space` can now be set to `39_bit`, `36_bit`, or `32_bit` to control the address space for hbl on a per-override basis.
+  + If a configuration has not been set, hbl will now default to 39-bit address space.
+    + Previously, a legacy 36-bit address space was always used to maintain compatibility with 1.0.0.
+    + A new loader extension was added to support 39-bit whenever possible (including mesosphere-on-1.0.0), with fallback to 36-bit when unavailable.
++ Support was added to a number of components for running on Mariko hardware.
+  + The `boot` system module can now safely be run on mariko hardware, performing correct hardware initialization.
+  + Daybreak (and generally, system update logic) were updated to be usable on Mariko.
+  + Boot0 protection/management logic was updated to perform correct actions on Mariko.
+  + Reboot to payload does not and cannot work on Mariko. Correspondingly, A "fatal error" handler was written, to display and save fatal errors from within TrustZone.
+  + **Please Note:** Atmosphere is still not properly usable on Mariko hardware.
+    + In particular, wake-from-sleep will not properly function (the magic numbers aren't set correctly), among a few other minor issues.
++ `exosphère` received support for building under debug configuration.
+  + A small (otherwise unused) portion of IRAM is now reserved for debug-only exosphere code (this region is unused/untouched under release config).
+  + This enables logging (including printf) to uart from the secure monitor, for those interested.
++ A number of bugs were fixed, including:
+  + Minor issues in a number of filesystem related code were fixed.
+  + An issue was fixed that could cause NCM to abort on consoles which came with 3.0.x and were never updated.
++ Several issues were fixed, and usability and stability were improved.
+## 0.15.0
++ fusee-primary's panic display was updated to automatically identify and give suggestions to resolve many of the most common errors users encounter.
++ Having been tested as well as I can alone, `mesosphere` (atmosphère's reimplementation of the Nintendo Switch kernel) is now available for users interested in trying it.
+  + Beginning in this release and until it is stable and well-tested, atmosphère will distribute two zips.
+    + Users who wish to opt-in to mesosphere should download and extract the "cool kids" zip ("atmosphere-EXPERIMENTAL-").
+    + Users who do not wish to use mesosphere should continue using the normal zip ("atmosphere-").
+  + Users may detect whether mesosphere is active in system settings.
+    + When mesosphere is active, the system version string will display "M.15.0" rather than "0.15.0", and so on for future releases.
+    + Crash reports and the like will contain information on whether or not the user is using mesosphere, as well.
+  + There are "probably" no material user-facing benefits to using mesosphere at this time.
+    + Developers may be interested in the fact that mesosphere provides many newer SVC APIs even when on lower firmware versions.
+    + The primary benefit to using mesosphere is that any issues you may encounter and report to me will be fixed.
+      + All users who choose to opt in to using mesosphere have my deepest gratitude.
+  + **Note:** If using hekate instead of fusee-primary, you will have to wait for the next hekate release for mesosphere to function, as hekate's support has not yet been included in an official release build.
+    + This will be updated in the release notes when hekate provides a new release.
+  + As mentioned in previous release notes, when mesosphere is stable and well-tested, it will be enabled by default and atmosphère's version will transition to 1.0.0.
++ Having been tested sufficiently over the last half-year, Atmosphere's NCM implementation is now opt-out, rather than opt in.
+  + In the unlikely event that any issues are encountered, please report them to @SciresM.
+  + Users interested in opting out of using our implementation should set `stratosphere!disable_ncm = 1` in BCT.ini.
+  + The NCM implementation will stop being opt-out in a future update, probably around the same time that mesosphere becomes opt-out instead of opt-in.
++ Several bugs were fixed, including:
+  + Loader now sets HBL's thread priority to a higher value when loading it in applet mode.
+    + This fixes an extremely-slow launch ("hang") when using applet-HBL with certain games that do not suspend while inactive (e.g. Super Mario Sunshine).
+  + set.mitm now caches user language configuration much more heavily.
+    + This severely reduces lag in certain games which misuse the "nn::oe::GetDesiredLanguage()" API.
+  + A bug was fixed that could cause erpt to fatal when loading an official save file that had error report attachments in it.
++ General system stability improvements to enhance the user's experience.
+## 0.14.4
++ Several bugs were fixed involving the official jit sysmodule added in 10.0.0.
+  + A Process handle leak was fixed when JitPlugin NRRs were registered with the `ro` sysmodule.
+    + This prevented processes using jit from being able to exit, causing a full system freeze.
+  + The `sm` atmosphere extension to not unregister services when the server's connection is closed was special-case disabled for `jit:u`.
+    + This extension is normally desirable in order to allow more concurrent processes to exist (as only 0x40 sm connections may ever be concurrently open), but official jit sysmodule relies on the behavior.
+    + This would cause crashes on attempts to launch a program using jit services more than once per reboot.
++ General system stability improvements to enhance the user's experience.
 ## 0.14.3
 + Support was added for 10.2.0.
 + General system stability improvements to enhance the user's experience.

+# DNS.mitm
+As of 0.18.0, atmosphère provides a mechanism for redirecting DNS resolution requests.
+
+By default, atmosphère redirects resolution requests for official telemetry servers, redirecting them to a loopback address.
+
+## Hosts files
+
+DNS.mitm can be configured through the usage of a slightly-extended `hosts` file format, which is parsed only once on system startup.
+
+In particular, hosts files parsed by DNS.mitm have the following extensions to the usual format:
++ `*` is treated as a wildcard character, matching any collection of 0 or more characters wherever it occurs in a hostname.
++ `%` is treated as a stand-in for the value of `nsd!environment_identifier`. This is always `lp1`, on production devices.
+
+If multiple entries in a host file match a domain, the last-defined match is used.
+
+Please note that homebrew may trigger a hosts file re-parse by sending the extension IPC command 65000 ("AtmosphereReloadHostsFile") to a connected `sfdnsres` session.
+
+### Hosts file selection
+
+Atmosphère will try to read hosts from the following file paths, in order, stopping once it successfully performs a file read:
+
++ (emummc only) `/atmosphere/hosts/emummc_%04lx.txt`, formatted with the emummc's id number (see `emummc.ini`).
++ (emummc only) `/atmosphere/hosts/emummc.txt`.
++ (sysmmc only) `/atmosphere/hosts/sysmmc.txt`.
++ `/atmosphere/hosts/default.txt`
+
+If `/atmosphere/hosts/default.txt` does not exist, atmosphère will create it to contain the defaults.
+
+### Atmosphère defaults
+
+By default, atmosphère's default redirections are parsed **in addition to** the contents of the loaded hosts file.
+
+This is equivalent to thinking of the loaded hosts file as having the atmosphère defaults prepended to it.
+
+This setting is considered desirable, because it minimizes the telemetry risks if a user forgets to update a custom hosts file on a system update which changes the telemetry servers.
+
+This behavior can be opted-out from by setting `atmosphere!add_defaults_to_dns_hosts = u8!0x0` in `system_settings.ini`.
+
+The current default redirections are:
+
+```
+# Nintendo telemetry servers
+127.0.0.1 receive-%.dg.srv.nintendo.net receive-%.er.srv.nintendo.net

+On startup (or on hosts file re-parse), DNS.mitm will log both what hosts file it selected and the contents of all redirections it parses to `/atmosphere/logs/dns_mitm_startup.log`.
+
+In addition, if the user sets `atmosphere!enable_dns_mitm_debug_log = u8!0x1` in `system_settings.ini`, DNS.mitm will log all requests to GetHostByName/GetAddrInfo to `/atmosphere/logs/dns_mitm_debug.log`. All redirections will be noted when they occur.
+
+## Opting-out of DNS.mitm entirely
+If you wish to disable DNS.mitm entirely, `system_settings.ini` can be edited to set `atmosphere!enable_dns_mitm = u8!0x0`.

 # Planned Features
 atmosphère has a number of features that are either works-in-progress or planned. Please note that while time-estimates are given, they are loose, and things may be completed sooner or later than advertised.
 
-The following descriptions were last updated on July 7th, 2020.
-
-## ams-on-mariko
-* **Description**: Atmosphere cannot run as-is on Mariko hardware. A large number of changes are needed in many components. Although secure monitor support is complete in exosphere, additional work is needed on the bootloader and stratosphere sides as well. Mariko support will also require further design thought; atmosphere's debugging design heavily relies on reboot-to-payload and (more generally) the ability to perform warmboot bootrom hax at will. This is not possible on Mariko, and will require a new design/software support for whatever solution is chosen.
-* **Development Status**: Planned.
-* **Estimated Time**: Summer 2020
-
-## settings reimplementation
-* **Description**: A planned reimplementation of the settings system module, and with it a removal of the settings mitm. This will greatly simplify atmosphère's boot process, and will allow much more flexible control over the various system settings.
-* **Development Status**: Undergoing research/initial development by Adubbz.
-* **Estimated Time**: Mid 2020
-
-## mesosphere
-* **Description**: mesosphère is a reimplementation of the Horizon operating system's Kernel. It aims to provide an open-source reference for Nintendo's code.
-* **Development Status**: Under active development by SciresM.
-* **Estimated Time**: Mid-to-Late 2020
+The following descriptions were last updated on January 14th, 2021
 
 ## tma reimplementation
 * **Description** tma ("target manager agent") is a system module that manages communication between the Switch and a client PC. Atmosphere's implementation will allow homebrew on the switch to communicate with a connected PC to do various operations such as exchanging data or interacting with files. It will also serve as the communicator for Atmosphère's planned debugger. This will also include PC-side software for interacting with the Switch.
 * **Development Status**: Planned. Switch-side code is fully implemented but needs heavy refactoring/rebasing, as the code was originally authored in 2018.
-* **Estimated Time**: Late 2020-2021.
+* **Estimated Time**: 2021-2022.
 
 ## dmnt.gen2 reimplementation
 * **Description**: A reimplementation of the Switch's debug monitor, dmnt will provide an interface for debugging applications or system modules running on the Switch. This will include a gdbstub for debugging actively-running system components or applications.
 * **Development Status**: Planned
-* **Estimated Time**: 2021
+* **Estimated Time**: 2021-2022
 
 ## fs reimplementation
 * **Description**: Following mesosphère's completion, atmosphère will have reimplemented all components of the BootImagePackage firmware except for the filesystem services system module. Reimplementing fs will allow for fixing Nintendo bugs (such as corruption when using exFAT filesystems and encoding inconsistencies with UTF-8 and Shift-JIS).
 * **Development Status**: Planned.
 * **Estimated Time**: 2021-2022.

+* **Description**: A planned reimplementation of the settings system module, and with it a removal of the settings mitm. This will greatly simplify atmosphère's boot process, and will allow much more flexible control over the various system settings.
+* **Development Status**: Pending development by Adubbz.
+* **Estimated Time**: Unclear, pending developer availability.
+
 ## thermosphère
 * **Description**: A general-purpose hypervisor, thermosphère will enable the virtualization of the Switch's operating system; this is planned to enable debugging of the Switch's kernel.
-* **Development Status**: Under semi-active development by TuxSH.
-* **Estimated Time**: 2020-2021.
+* **Development Status**: Pending development by TuxSH.
+* **Estimated Time**: Unclear, pending developer availability.
 
 ## other planned features
 * **Description**: General system stability improvements to enhance the user's experience.

 ## exosphere re-write
 * **Description**: exosphère, atmosphère's reimplementation of Horizon's Secure Monitor, was the first component authored for the project in early 2018. It is written in C, and in a style very different from the rest of atmosphère's code. In addition, exosphère was written to conform to constraints that no longer apply in an environment where it is not launched from the web browser, and where using a custom firmware image to orchestrate wake-from-sleep is possible. exosphère currently uses all but 1 KB of the space available to it, putting it at risk of breaking as future firmware updates are supported. A re-write will solve these issues.
