12.0 Alpha2 - RPi3 support?

[Mike]

Did I miss a memo?  :)

On this ISO download page:
https://download.freebsd.org/ftp/snapshots/arm64/aarch64/ISO-IMAGES/12.0/


Prior to Alpha2, there was an image file for RPi3.  For example:

FreeBSD-12.0-ALPHA1-arm64-aarch64-RPI3-20180810-r337557.img.xz


With Alpha2, all I see is a memstick file:

FreeBSD-12.0-ALPHA2-arm64-aarch64-20180816-r337934-memstick.img.xz


and nothing specifically for RPi3.

I looked around in google but I saw nothing pointing me to a place where
I can learn how to use the memstick file on my RPi3.

What am I missing?  Or has RPi3 support been dropped for 12.0?

thx.
