+  * Fix Table Generation generating incorrect parsers when there

+  * GLR parsers now support %merge together with
+    api.value.type=union
+  * C++ parsers use noexcept in more places
+  * Generated parsers avoid some warnings about signedness issues
+  * C-language parsers now avoid warnings from pedantic clang
