libnx 4.0.0 Released

libnx 4.0.0

Beyond the possibilities offered by the console hax, there are some developers like Yellows8 or fincs who are trying to bring the homebrew part of the Nintendo console to life.
 
The efforts they implement are numerous but this particularly involves the proposal of all-in-one libraries which are supposed to facilitate the work of the developers of hombrews.
 
The biggest proposal is made by fincs with libnx which unveils version 4.0 of its program with a stratospheric changelog.

Changelog Version 4.0.0

    #### system
    * **Added support for the light event synchronization primitive** (needs [4.0.0+] or mesosph√®re).
    * **The virtmem API was completely redesigned** to support ASLR and increase thread safety.
    * **Added diagAbortWithResult**, an overridable user panic function which is intended to replace fatalThrow in order to stop homebrew from treating application errors as fatal system errors that bring the entire OS down.
      * The default implementation uses svcBreak.
      * Replaced calls to fatalThrow with diagAbortWithResult throughout libnx.
    * Added detectMesosphere.
    * Added svcGetResourceLimitPeakValue [11.0.0+].
