+- update to v100
+  * `wasm-dis` now supports options to enable or disable Wasm features.
+  * Reference types support has been improved by allowing multiple
+    tables in a module.
+  * `call_indirect` and `return_call_indirect` now take an additional
+    table name parameter. This is necessary for reference types support.
+  * New getter/setter methods have been introduced for `call_indirect`
+    table name:
+    - `BinaryenCallIndirectGetTable`
+    - `BinaryenCallIndirectSetTable`
+    - JS API `CallIndirect.table`
+  * New APIs have been added to add and manipulate multiple tables
+    in a module:
+    - `BinaryenAddTable`
+    - `BinaryenRemoveTable`
+    - `BinaryenGetNumTables`
+    - `BinaryenGetTable`
+    - `BinaryenGetTableByIndex`
+    - `BinaryenTableGetName`
+    - `BinaryenTableGetInitial`
+    - `BinaryenTableHasMax`
+    - `BinaryenTableGetMax`
+    - `BinaryenTableImportGetModule`
+    - `BinaryenTableImportGetBase`
+    - `module.addTable`
+    - `module.removeTable`
+    - `module.getTable`
+    - `module.getTableByIndex`
+    - `module.getNumTables`
+    - `binaryen.getTableInfo`
+
