General Updates
Update to Eclipse Luna SR1
STS and GGTS now ship on top of the latest Eclipse Luna SR1 release. This Eclipse release includes numerous Java 8 compilation fixes.
Gradle Tooling
Gradle 2.1 has been adopted.
It is now possible to stop/cancel Gradle tasks due to enhancements in the gradle tooling API. Use the terminate button in the Console view (which used to be disabled). Furthermore, any Gradle operation (Gradle, build, import, model construction, etc.) can either be stopped from a progress dialog (if applicable) or from the Progress view just like any other task in Eclipse.
Miscellaneous
Here is a full list of resolved bugs and enhancement requests for 3.6.2:

The OSX platform specific signing of the STS and GGTS Mac apps is not yet updated to a Mavericks infrastructure. Therefore running STS/GGTS on OSX 10.9.5 and OSX 10.10 will cause Gatekeeper to complain about STS/GGTS. In that case, please go to the System Preferences -> Security and do "Open Anyway". If that doesn't work, you have to disable the Gatekeeper checks to allow every app to run. Then start STS/GGTS. Once you started STS/GGTS at least once successfully, OSX will remember your decision about this app, will not ask you again, and you can switch back Gatekeeper security settings to a more secure mode again.
Doing a "Check for Updates" of STS to an existing installation throws an error about a problem with the Groovy-Eclipse JDT patch feature. In that case, disable the Groovy-Eclipse JDT patch feature from the list of components to update and continue. This happens on the Eclipse 4.3 platform only. If you upgrade from STS 3.6.0 or 3.6.1 on Eclipse 4.4, you will not hit this problem.
When running STS/GGTS on top of a JDK7, the new dashboard looks a bit blurry when using a HiRes (Retina) display, for example on a Retina MacBook Pro. This is due to the underlying browser technology that is used to display the dashboard content and that is coming from JavaFX. The JavaFX version that ships with JDK7 doesn't support retina displays. The solution for this is to run STS/GGTS on top of a JDK8 build. The JavaFX version that comes with JDK8 supports retina displays.
STS and GGTS requires a JDK to run on top of. Nevertheless the native launcher component might pick up a JRE automatically if you don't specifiy which JDK to run STS/GGTS on top of. To avoid this, you can specify the JDK in the sts.ini file that comes with your STS/GGTS installation. Add a line at the beginning "-vm" and an additional line below that which points to the "javaw" executable of the JDK on your machine.
Eclipse 4.4, upon which STS and GGTS are based, is the first Eclipse release where GTK3 is the default for the SWT widget library. There are some issues with this still:
You may also experience other UI rendering glitches. If you exprience any of these problems you can avoid them by forcing SWT to switch back to using GTK2. Just set the environment variable "SWT_GTK3=0" before launching STS or GGTS.
