The `arm-neon` branch was merged into `master`. It includes the NEON implementations of BLAKE2. Git does not provide a log entry for the merge, so I don't have a record to offer for the transaction. I recently learned I have to do something special to have Git generate a log entry and avoid polluting Master's logs with problems that did not exist in Master (http://stackoverflow.com/questions/5308816/how-to-use-git-merge-squash). I think we should keep arm-neon around for additional ports to arm-neon. We have detection code for ARM's AES, SHA1 and SHA2 extensions, so there's opportunities available for anyone interested in the port. We can also port anything with SSE2. With respect to SSE2, I've found the specialized NEON implementations based on SSE2 outperform the native code generated from C++ by about 3 cycles per byte.
