title: ButterKnife findByID method is deprecated in version 8.8.0
body: <p>Hi I have just updated ButterKnife library version 8.7.0 to 8.8.0 </p>
  
  <pre><code>compile 'com.jakewharton:butterknife:8.8.0'
  annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.0'
  </code></pre>
  
  <p>and found that:</p>
  
  <pre><code>findById(view, id);
  </code></pre>
  
  <p>is deprecated, why? what method to use instead? 
  but when reverting version to 8.7.0 (or earlier) deprecated warning disappears.</p>
  
  <pre><code>compileSdkVersion 25
  buildToolsVersion "25.0.3"
  defaultConfig {
      applicationId "com.some.app"
      minSdkVersion 21
      targetSdkVersion 25
  ...
  </code></pre>
