NetBSD team announced 7.1 release on 11 of March, 2017. Release announcement is available here. You can download it from any of the mirrors using torrents, FTP or other services. Full list of changes can be found here. Main highlights are Raspberry Pi Zero support, initial DRM/KMS support for NVIDIA graphics via nouveau (Disabled by default. Uncomment nouveau and nouveaufb in your kernel config to test), the addition of vioscsi, a driver for the Google Compute Engine disk, improved Linux compatibility and numerous bug fixes and stability improvements.

On the side note NetBSD is accepted as one of mentoring organizations in the 2017 Google Summer of Code. Initial proposals can be found here but official application process will start at 20th of March.

In meantime I have already started to play with NetBSD current (future 8 release) already. It lead to one bugfix for VIA RNG already. Hope to find more in the future.
