   * 'webgl2': Use the `WebGL2Kernel` for transpiling a kernel
   * 'headlessgl' **New in V2!**: Use the `HeadlessGLKernel` for transpiling a kernel
   * 'cpu': Use the `CPUKernel` for transpiling a kernel
-* `onIstanbulCoverageVariable`: For testing. Used for when coverage is inject into function values, and is desired to be preserved (`cpu` mode ONLY).
-  Use like this:
-  ```js
-  const { getFileCoverageDataByName } = require('istanbul-spy');
-  const gpu = new GPU({
-    mode: 'cpu',
-    onIstanbulCoverageVariable: (name, kernel) => {
-      const data = getFileCoverageDataByName(name);
-      if (!data) {
-        throw new Error(`Could not find istanbul identifier ${name}`);

-      const { path } = getFileCoverageDataByName(name);
-      const variable = `const ${name} = __coverage__['${path}'];\n`;
-      if (!kernel.hasPrependString(variable)) {
-        kernel.prependString(variable);
-      }
-    }
-  });
-  ```
-* `removeIstanbulCoverage`: Boolean. For testing and code coverage. Removes istanbul artifacts that were injected at testing runtime.
+* `onIstanbulCoverageVariable`: Removed in v2.11.0, use v8 coverage
+* `removeIstanbulCoverage`: Removed in v2.11.0, use v8 coverage
 
 ## `gpu.createKernel` Settings
 Settings are an object used to create a `kernel` or `kernelMap`.  Example: `gpu.createKernel(settings)`
