-## About this release
-
-This release, in the `nvdlav1` branch, contains the non-configurable
-"full-precision" version of NVDLA.  This non-configurable version is fixed
-at 2048 8-bit MACs (or 1024 16-bit fixed- or floating-point MACs).  This
-branch is expected to be a stable sustaining release; although bug fixes may
-be added, new RTL feature improvements will not appear in this branch. 
-Additionally, this branch will diverge from the `master` branch; commits
-from that branch may be cherry-picked into this branch, but wholesale merges
-from `master` will not appear on `nvdlav1`.
