This release fixes a number of minor issues reported by users.
Most importantly the sysmodule and settings app are now built using latest libnx for 21.0 support.
Since 21.0 further reduced the available memory for sysmodules remember that you can load and unload SysDVR at any time from the settings app. You can also use the usb-only build which does not support streaming over the network but uses less memory.
For reference, as of this release SysDVR uses slightly less than 1MB of ram while the usb-only version around 500KB.
