ARM64 (aarch64) Android client in beta testing
This is a bare bones client without NEON optimized routines for SETI@home, but does have NEON FFTW routines. It'll be a while before I can modify the ARMv6 NEON routines to work when compiled under aarch64.

Distributing 4-bit workunits
This has been in the works for a while. I'll be distributing some workunits with 4-bit complex samples. They'll be twice the size of the current 2-bit workunits, but will give us 46% reduction in noise power.
It's possible that some of the app versions date from before the 4-bit quantization code existed in the client (but I don't think so). If things are going to break it should be obvious pretty quickly.
The change should occur this afternoon.

Arecibo still threatened with closure.
Recently the NSF announced its intent to start the process which could lead to the partial shutdown, mothballing, or complete disassebly of the Arecibo Observatory. As most of you know, this is not a new discussion in the scientific community. Several years ago we had asked you write letters to Congress in hopes of averting this fate.
A petition has been started on whitehouse.gov to ask the President to ensure it is funded. I'm pessimistic about the chances that it will change anything, as the President cannot change Congressional budget priorities, and only has limited ability to move money between NSF programs. However, bringing attention to the issues of science funding in this country cannot hurt.

New Android apps for SETI@home v8
There was a problem with the first set of android apps due to a problem with how the FFTW library measures time. Any work you got for an android SETI@home v8 before today can be aborted.
I've fixed the bugs and released version 8.01 which should run much better.

SETI@home v8 beta to begin on Tuesday
Finally we have a working GBT splitter. SETI@home v8 will process Arecibo and GBT data.
The code changes are pretty small, but the results are not compatible with SETI@home v7, so only process v8 data will v8 clients.
First release will be linux x86_64 only to begin with. We're hoping to have windows and macos graphical releases in another week or so.
