Removing Ignored Android Studio (or Intellij) Update Builds

When an Android Studio update is posted and you mistakenly click on Ignore This Update how do you apply the update without having to reinstall Android Studio?

Update

As of the latest version of Android Studio, there is now a Preference in the UI noted in an answer by Yogesh Umesh Vaity

Original Answer

The simple way to revert a mistaken choice is to close Android Studio then edit other.xml file and remove the myIgnoredBuildNumbers option block:

<option name="myIgnoredBuildNumbers">
  <value>
    <list size="1">
      <item index="0" class="java.lang.String" itemvalue="130.729444" />
    </list>
  </value>
</option>

Technically you should edit the size and remove the item in question but after some testing the next time you ignore a build the myIgnoredBuildNumbers block will be rebuilt.

The other.xml file can be found at:

• OSX: ~/Library/Preferences/AndroidStudio/options/other.xml
• WIN: %HOMEPATH%\.AndroidStudio\config\options\other.xml
• NIX: ~/.AndroidStudio/config/options/other.xml

The same can be done in Intellij in the following paths:

• OSX: ~/Library/Preferences/IdeaIC12/options/other.xml
• WIN: %HOMEPATH%\.IdeaIC12\options\other.xml

As of Android Studio 1.2(possibly earlier), the ignored builds block is defined in updates.xml within the same directory as other.xml

There is an easier way to do this now. Android Studio has an option to delete the ignored updates in Preferences.

Go to:

Preferences > Appearance & Behavior > System Settings > 
Updates > View/edit ignored updates

A list of ignored updates will be opened. Just remove the updates that you don't want to ignore.

Updating hoss' answer:

I have been using Android studio 1.4 on Mac OSX and happened to ignore update 1.5. The ignored build numbers are located in "updates.xml" at the following path.

/Users/YOUR_USER_NAME/Library/Preferences/AndroidStudio1.4/options/updates.xml

Remove the "ignoredBuildNumbers" section from the updates.xml file and save it. Make sure you are updating the file in Android studio folder corresponding to version you are using. Another thing to note is, make sure you quit Android studio before updating the file. Else Studio will overwrite the xml file with previous data from memory. Edit the file and start Android studio again.

Quit studio > Edit "updates.xml"> Start studio

In case, that doesn't still work, switch to Canary channel and check for update. If there is an update, choose "Remind me later" option. Then switch back to STABLE channel and again check for update. It should be working now.

currently I'm using IDEA 14.0.4. I found the myIgnoredBuildNumbers option block in "users/username/.IntelliJIdea14/config/options/updates.xml"

Removing the entire block and restarting will show the previously ignored release/build

  <option name="myIgnoredBuildNumbers">
       <value>
           <list size="1">
               <item index="0" class="java.lang.String" itemvalue="141.713"/>
           </list>
       </value>
    </option>
