What’s New in IntelliJ IDEA 2020.1 EAP 2? Debugger, Zen Mode, and More

IntelliJ IDEA 2020.1’s second early‑access build has been released, bringing debugger and profiler improvements, a new Commit tool window, and Zen Mode.

Data‑flow analysis assistance for the debugger

When debugging Java code and hitting a breakpoint, the IDE runs data‑flow analysis based on the current program state and shows possible exceptions and conditions that are always true or false.

Collapsing recursive calls

IDEA can now detect recursive calls higher in the stack and suggests extracting them from the call‑tree, allowing developers to focus on resource‑intensive methods. Recursive calls are shown with a new special icon in the Call Tree tab.

New Commit tool window

The 2020.1 release adds a new tool window for the Commit UI, containing “Local Changes” and “Shelf” tabs. It consolidates all commit‑related tasks such as reviewing diffs, selecting files or hunks, and writing commit messages.

Zen Mode

Zen Mode combines Do‑Not‑Disturb and full‑screen modes to eliminate distractions and let developers focus entirely on code. Activate it via View | Appearance | Enter Zen Mode or the quick‑switch dialog (Ctrl+` | View mode | Enter Zen Mode).

LightEdit mode

LightEdit provides a lightweight editor for opening and editing files without creating or loading a project, catering to users who want IntelliJ IDEA to serve as a general‑purpose text editor. The simplest way to try LightEdit is to open a file from the command line.
