## Change 1.8.0 ## Change The deprecated App Engine standard Java 7 runtime will soon be removed from production. In this release of Cloud Tools for Eclipse, the new project wizards only generate Java 8 App Engine projects. A warning dialog is displayed when attempting to deploy a Java 7 project. Warning markers are shown on Java 7 and Java 6 projects. Quick fixes are available to convert Java 7 and Java 6 projects to Java 8 projects. ## Feature Quick fixes in the source editor have a larger target area including start and end-tags. ## Fix An uncommon null pointer exception that could occur when a project was deleted has been fixed. ## Fix `min-instances` can now be set to zero in appengine-web.xml for automatic scaling. ## Issue If you downgrade or remove the runtime element in appengine-web.xml, you may see multiple build errors until you clean or rebuild the entire project.
