Zlata Kalyuzhnaya

It’s here! Please give a warm welcome to IntelliJ IDEA 2018.3. This year’s third major update delivers notable features that you just can’t miss! Visit What’s new for a detailed overview, or go straight to the website and download the brand new version of IntelliJ IDEA right now. Keep reading for a brief summary.

Java

• The IDE can now spot duplicates in more complicated cases, and it does this faster as well.
• Java Stream API improvements: redundant sorted calls that are made before the subsequent min call are now detected.
• A new data-flow-based inspection detects situations where the first condition is unnecessary because it’s already covered by a second condition.
• The IDE now identifies situations where a suppressed inspection no longer addresses any warnings in the associated method body, class, or statement.

Find more details in the Java section of the What’s new page.

• The IDE highlights the first and all subsequent TODO comment lines in the editor and displays them in the TODO tool window.
