* Support was added for the new c-ares resolver in dns.mitm.
** Firmware 23.0.0 introduced a new set of commands to the sfdnsres service. These commands provide c-ares async support for DNS resolution and are now used by most sysmodules.
** This resulted in host redirection not being applied at all and without warning since we simply were not intercepting the new commands.
** dns.mitm now fully reimplements the c-ares serialization code and intercepts the relevant commands. In tandem with the bsdsocket sysmodule, we now keep track of resolution queries and redirect their results.
* Support was added for the new "BatchRead" storage in fs.mitm.
** Firmware 23.0.0 introduced a new type of filesystem storage object abstracted by the interface "IStorageForBatchRead". This is a derived class from "IStorage" with the purpose of adding the new "BatchRead" command.
** Anything that uses the filesystem API now attempts to use this type of storage instead of the old one. This is of particular relevance for qlaunch and for supporting custom themes which were broken as a consequence of this change.
** fs.mitm was updated and extended to not only support the new storage type but also intercept a few newer commands that were previously missing.
* The patches for the browser applets were redesigned.
** The introduction of these patches in the previous release led to several issues and crashes, notably during media playback in the eshop and within games that use LibAppletOff.
** After extensive analysis and testing it was concluded that the browser applets were running out of memory and still required reducing the memory we reserve for custom sysmodules.
** New patches have been devised and introduced in this release.
*** Instead of patching size checks, we now trick the browser applets into thinking there is 1GB of free memory available to them.
*** Unused memory is still being reclaimed and discounted from the root heap, but now more realistically.
*** The browser engine's heap is now being shrunk with no noticeable downsides to media playback nor web page rendering.
** Thanks to these changes we can now provide 40MB for custom system modules once again.
* A number of minor issues were fixed and improvements were made, such as:
** Automatic PRODINFO backup was fixed for recent console models that no longer use the ECC device certificate (thanks @chrisbraucker).
** State initialization for SharedMemory and TransferMemory was fixed (thanks @fl0be).
** Compatibility was fixed for Trails in the Sky 2nd Chapter (thanks @masagrator).
* General system stability improvements to enhance the user's experience.
