Key Highlights

Full support for Java 21 features

IntelliJ IDEA 2023.3 provides full support for the latest Java 21 features. These updates include important new features such as virtual threads, record modes, pattern matching for switch expressions, and serialized collections, as well as previews of newly introduced language features such as string templates, scoped values, and more.

Run to Cursor embedded option in debugger

IntelliJ IDEA 2023.3 introduces a new Run to Cursor embedding option that allows you to execute to specific lines of code while debugging. After the program hangs, you can hover over the line of code you want to execute to and click on the Run to Cursor popup. You can also use this feature by invoking the keyboard shortcut (⌥F9) after placing the text cursor on the desired line.

Floating toolbar with editing operations

IntelliJ IDEA 2023.3 introduces a floating toolbar that appears next to the selected code snippet, providing editing operations such as Extract, Surround, Reformat, and Comment as well as context Easy access to operations. You can customize the floating toolbar using the three-dot menu. To hide it you can use the same menu or go to Settings/Preferences | Advanced Settings | Editor and check Hide floating toolbar for code editing ) option.

User experience optimization

Default tool window layout options

IntelliJ IDEA 2023.3 further enhances the ability to save multiple tool window layouts and switch between them introduced in v2023.1. The new Default (default) layout option provides a quick way to restore the appearance of your workspace to its default state. This layout is not customizable and is located under Window | Layouts.

Default color-coded editor tabs

To enhance your navigation experience when working with multiple file types simultaneously in the editor, we've introduced default color coding for editor tabs to reflect their appearance in the Project tool window. You can manage this setting in Settings/Preferences | Appearance & Behavior | File Colors.

Option to hide main toolbar in default viewing mode

New product icons for macOS

There are other optimizations, such as improvements to Java, Scala, Kotlin, etc.

Build tool

Faster Gradle import and indexing

Gradle projects now open faster because the IDE no longer automatically downloads source JAR files for all dependencies. To access a specific source file, you can navigate using the ⌘B shortcut key and select Download when prompted by the IDE.

Fast Maven import for all projects

performance

Shared JDK index download enabled by default

In order to improve the startup speed of the IDE, we enable the download of the shared JDK index by default. IntelliJ IDEA will now seamlessly connect to proprietary resources behind the scenes, automatically fetching and applying shared indexes for the JDK.

In the past two days of use, IDEA has become easier and easier to start and run, especially the genuine version I use, which can be said to be very smooth haha.
