 ## News
 
+- Nov 9:
+  - fixed unary and binary operators on beignet
+  - note that the tools/bazel.rc.templ has changed.  Please make sure to copy the new value into tools/bazel.rc, or re-run configure (probably need to do `bazel clean` anyway, so might as well do `./configure`)
 - Nov 1:
   - building clew, CLBlast, easycl, cocl as shared libraries now, rather than static
     - hopefully this will facilitate debugging things on the HD5500 on my laptop, since dont need to build/install entire wheel, for `libcocl` tweaks
