[Discuss-gnuradio] [VOLK] Release v1.2.1 (and v1.2) announcement

[West, Nathan]

I released v1.2 in late December and never announced it to this list or updated the website, so surprise! There's now a v1.2.1. Talladega Nights became available on netflix, so it was definitely time. Notes follow and the website (http://libvolk.org) is updated. Raw notes available at the usual place for those packagers that like such things: http://libvolk.org/news_raw/ as well as the tag annotation.

Changes

Profiler

• Fixed a segfault in the polar butterfly puppet
• Reverted back to input values in range [-1, 1] rather than [-pi, pi].

Builds (all windows related)

• Add MSVC 14 to processor detection
• Minor tweaks to fix builds on MSVC 2015

Kernels

Small performance improvement in log2 by switching to log2f, which is explicitly for floats.

Add reusable intrinsics for NEON. This continues the push for creating an internal library of intrinsics that will make composing more complex kernels from simpler reusable building blocks without going back to memory.

Shake and bake,

Nathan
