 ### Release Retention Policy
 
@@ -46,13 +48,25 @@ Available targets:
 * `win64` (x86_64 Windows)
 * `win32` (x86 Windows)
 * `linux64` (x86_64 Linux, glibc>=2.23, linux>=4.4)
+* `linuxarm64` (arm64 (aarch64) Linux, glibc>=2.27, linux>=4.15)
+
+The linuxarm64 target will not build some dependencies due to lack of arm64 (aarch64) architecture support or cross-compiling restrictions.
+
+* `libx11` and dependencies: libx11 and its dependencies don't seem to support cross-compiling.
+* `SDL`: Because it depends on libx11.
+* `davs2` and `xavs2`: aarch64 support is broken.
+* `libmfx` and `libva`: Library for Intel QSV, so there is no aarch64 support.
+* `ffplay` binary: Because it depends on libx11 and SDL.
 
 Available:
 * `gpl` Includes all dependencies, even those that require full GPL instead of just LGPL.
 * `lgpl` Lacking libraries that are GPL-only. Most prominently libx264 and libx265.
+* `nonfree` Includes fdk-aac in addition to all the dependencies of the gpl variant.
 * `gpl-shared` Same as gpl, but comes with the libav* family of shared libs instead of pure static executables.
 * `lgpl-shared` Same again, but with the lgpl set of dependencies.
+* `nonfree-shared` Same again, but with the nonfree set of dependencies.
 
 All of those can be optionally combined with any combination of addins.
 * `4.4` to build from the 4.4 release branch instead of master.
+* `5.0` to build from the 5.0 release branch instead of master.
 * `debug` to not strip debug symbols from the binaries. This increases the output size by about 250MB.
