 If not stated, FINUFFT is assumed (cuFINUFFT <=1.3 is listed separately).
 
+V 2.3.0beta (6/21/24)
+
+* Major acceleration of spread/interp kernels using XSIMD header-only lib,
+  kernel evaluation, templating by ns with AVX-width-dependent decisions.
+  Up to 80% faster, dep on compiler. (Marco Barbone with help from Libin Lu).
+    NOTE: introduces new dependency (XSIMD), added to cMake and makefile.
+* new perftest/compare_spreads.jl compares two spreadinterp libs (A Barnett).
 * new benchmarker perftest/spreadtestndall sweeps all kernel widths (M Barbone).
 * cufinufft now supports modeord(type 1,2 only): 0 CMCL-style increasing mode
   order, 1 FFT-style mode order.
