title: go version command shows old version number after update to 1.8
body: <p>Pretty much the title. I downloaded/installed Go 1.8 for OS X, but when I go</p>
  
  <pre><code>$ go version
  go version go1.7.5 darwin/amd64
  </code></pre>
  
  <p>My .bashrc look like the following</p>
  
  <pre><code># some exports omitted
  
  NPM_PACKAGES=/Users/&lt;me&gt;/.npm-packages
  NODE_PATH="$NPM_PACKAGES/lib/node_modules:$NODE_PATH"
  
  export PATH=~/Library/Python/3.4/bin:$PATH
  
  export GOPATH=$HOME/Go
  export PATH=$PATH:/usr/local/go/bin
  </code></pre>
  
  <p>My workspace is in a directory called "Go" in my home folder. </p>
  
  <p>What I have checked so far:</p>
  
  <ul>
  <li><p>I've checked the files in /usr/local/go/bin, and the VERSION file states "1.8", so I know the installation was successful.</p></li>
  <li><p>I have also renewed my terminal session, I even rebooted my pc to make sure no other processes were interfering with it.</p></li>
  <li><p>I use Webstorm as my IDE, and it correctly recognized 1.8 as the working version</p></li>
  <li><p>It's not a bug in the version number itself, as I can't use the "NextResultSet()" sql functionality, introduced in version 1.8</p></li>
  </ul>
  
  <p>I believe the culprit might be a wrong configuration in the .bashrc file above, as only the terminal is stuck on the old version, but I can't figure out what is wrong with it.</p>
