Windows 10 users should take note. The Eclipse Foundation warns that by default, Windows 10 Defender slows down and freezes Eclipse. This bug is not unique to Eclipse and is related to Windows Defender scanning JAR files.

Thanks to Holger Voormann (@howlger on Twitter), two informative videos summarize the long list of changes.

Java improvements

This update includes support for Java 13 and adds the Switch Expressions (JEP 354) and Text Blocks (JEP 355) features. (Since these features are in the preview phase, you must enable the preview options in order to use them.)

A new keyboard shortcut for creating text blocks also comes packaged in this update. Simply use Ctrl + Shift + ‘ in the Java Editor.

Other additions to the Java Editor include a new cleanup action for removing unnecessary array creations, a new cleanup/save action that reduces double negation, and new basic templates for empty Java source files.
