+2.0.0
+=====
+
+* Update to reed-solomon-32 version 2.0.0. Significantly, that version pre-computes
+  values that used to be computed at runtime. This allows us to simplify our
+  API to primary just use free-functions that use those pre-computed tables as opposed
+  to having to manually manage objects that contain runtime-computed values.
+* Some users may wish to keep binary size to a minimum (eg, such as for WASM output).
+  In order to minimize binary size, we create a lower-level interface that allows
+  for a particular ECC size to be chosen at compile time. When using this interface,
+  unneeded precomputed tables may be eliminated from the final binary at link time.
+* Update to libzbase 2.0.0 - this doesn't impact the features of this library.
+* Update the Error APIs to make it easier to differentiate between input related
+  errors and usage related errors.
+* Fix incorrect use statements that were preventing the no_std mode from actually
+  working.
