| The release notably includes the following Java 12 feature: |

| Please note that this is a <a href="http://openjdk.java.net/jeps/12"> preview language feature</a> |

| Instead of a single line wrapping setting for binary expressions, there's now a whole section of settings for various kinds of <b>binary operators</b> (multiplicative, additive, logical, etc.). |
| There are settings for <i>relational</i> (including equality) and <i>shift operators</i>, which were not covered by the old setting. |
| Also, <i>string concatenation</i> can now be treated differently from arithmetic sum. |
| <p> |
| The settings can be found in the Profile Editor (<b>Preferences > Java > Code Style > Formatter > Edit...</b>) under the <b>Line Wrapping > Wrapping settings > Binary expressions</b> subsection. |
