Updated Support for AARCH64 (markdown)

 * Current status: nothing publicly released yet.
 
-* ARM support will be source code only, no binaries are planned.
-* Coding is progressing with many issues translating SSE to NEON. Some things are done very differently and some things may not be possible.
-* The lack of flexible lane shuffling is a major problem. Some shuffles may have to be done by inserting one lane at a time.
-* Current expectations are best performance will be with sha256 based algos. AES is only supported for shavite.
-* Parallel 4 way hashing will not be provided initially but will be added later.
-* Current problem algos include anything with Groestl, Echo & Fugue due to problems with the AES implementation.
-* Simd has a problem with multiplication that I haven't resolved.
-* Scrypt has issues with the lack of a blend instruction in NEON that requires a workaround. The lack of mask creating doesn't make it any easier.
-* Yespower/yescrypt also have issues that aren't fully understood due to the complexity of the current code.
-* Unresolved issues will result in using completely unoptimized "reference" code.
+Optimizations available in first public release:
+
+* all variations of blake have linear and parallel vectorization
+* all variations of sha256 have parallel and HW accelerated optimizations
+* algorithms that use shavite have AES HW acceleration
+* algorithms that use luffa or cubehash have linear vectorization
+
+x86_64 optimizations disabled for ARM:
+
+* aes is disabled for Groestl, Echo, and fugue.
+* Simd (the hash function, not the CPU feature) linear vectorization is disabled
+* Yespower, yescrypt, scrypt & argon2d optimizations are disabled
