+### Bug Fixes

+- Fixed grpcio-tools build dependency issue. Under certain circumstances (e.g., use of an older grpcio package), the
+  installation will fail due to an incompatible grpcio-tools version getting installed at build time. The grpcio-tools
+  version has been fixed for the build at 1.59. As a result the grpcio version also must at least be 1.59
