Light theme with light header in the new UI
For v2023.2, we’ve refined the user experience with the Light theme by introducing the Light with Light Header alternative, which features matching light colors for window headers, tooltips, and notification balloons.
Updated window controls on macOS
If you use full screen mode in the new UI on macOS, the window controls are now displayed right in the main toolbar, not in the floating bar as before.
Removed title bar on Linux in the new UI
For the convenience of Linux users, the native header of the operating system has been removed in the new UI, resulting in a cleaner interface. By default, you will now see the IDE’s custom header, which offers a range of customization options to tailor your workspace. If you want to revert the header to its previous appearance, uncheck the Merge main menu with window title option in Settings | Appearance & Behavior | Appearance | UI Options.
Syntax highlighting in inspection descriptions
In Settings / Preferences | Editor | Inspections, code samples now include syntax highlighting, which makes it easier to understand what triggers an inspection and decide whether you want it to be active or inactive.
Single-click navigation between project directories
In the Project view, there’s a new Open Directories with Single Click option that makes expanding and collapsing the project folders quicker and more responsive. The option is available from the drop-down menu once you click on the kebab (three vertical dots) menu.
Improved main toolbar customization
We’ve expanded the customization options for the new UI’s main toolbar. You can now use a dropdown menu to quickly choose actions that you want to add to the toolbar. To do so, right-click on any widget, select Add to Main Toolbar, and explore the available options.
Suggested plugins in Settings/Preferences
To make it easier to configure the IDE for your specific projects and extend its functionality with plugins, we have updated the UI for the Settings/Preferences | Plugins section.

New inspections and other code analysis improvements
We have improved and expanded Java inspections to help you maintain high-quality code and detect potential issues more effectively. The new Incorrect ‘MessageFormat’ pattern inspection will warn you when pattern references do not match the arguments, and it will also detect incorrect usages of quotes and braces in MessageFormat patterns. Also, the IDE now reports calls with explicit ChronoField or ChronoUnit arguments and suggests replacing them with calls of more specific methods, thus simplifying the code. Learn more about the new inspections and other code analysis improvements in IntelliJ IDEA 2023.2 in this blog post.
Сode highlighting and navigation for format strings
Now, once you place the caret on a format specifier, the IDE will highlight the corresponding argument and other specifiers that point to it. Also, you can now use Go To Declaration (⌘B) to jump to the associated code location for a specific format string placeholder.
PreviousNext
Improved support for the @snippet tag in Javadoc comments
IntelliJ IDEA now features improved @snippet tag functionality in Javadoc comments. It allows Markup comments within the @snippet tag and renders them properly in the documentation. Code regions are now supported, meaning you can specify a portion of code that you want to refer to in a Javadoc comment. In addition, the IDE now supports the inclusion of external snippets within the @snippet tag, allowing you to reference code snippets stored in separate files or sources and include them in Javadoc documentation.
PreviousNext
Expanded refactoring options for multiple selected members
We’ve added new ways to apply certain refactorings to several members at once. You can now invoke Extract Delegate, Extract Interface, Extract Superclass, Pull Members Up, and Push Members Down on multiple members simultaneously by selecting them right in the Project or Structure tool window. In addition, IntelliJ IDEA now supports multi-caret selection for an extended range of refactorings, including Encapsulate Fields, Move Static Members, Extract Delegate, Extract Interface, and Extract Superclass. To utilize this feature, place a caret in each member you want to apply the refactoring to, and the IDE will automatically preselect and check these members in the refactoring dialog.
Improved navigation for stack trace analysis
To facilitate stack trace analysis and make resolving bugs quicker, IntelliJ IDEA can now accurately guess the location of a method in the report even when line numbers are not available or have diverged.
Enhanced taint analysis for dynamic SQL queries
Ultimate
IntelliJ IDEA can now better analyze concatenations and interpolations of SQL in Java and Kotlin, detecting potentially unsafe queries and thereby protecting the code from possible SQL injection vulnerabilities.
Scala
PreviousNext
Better Scala 3 support
IntelliJ IDEA 2023.2 brings enhanced Scala 3 support, with a focus on providing a streamlined development experience. Notable improvements include fixes for Scala 3 enum highlighting, navigation to enum definitions, and the correct resolution of enum cases in various contexts. The TASTy decompiler has been significantly enhanced, ensuring accurate decompilation of popular Scala libraries, such as Akka, Cats, Play, ZIO, and others. Additionally, the integration of scala-expression-compiler into the debugger provides a better debugging experience for Scala developers. Other improvements include enhanced completion hints for Scala 3’s Universal Apply Methods, in-editor support for IArray, and improved support for the “fewer braces” syntax.
Better sbt support
This release comes with many improvements to IntelliJ IDEA’s sbt support. Environment variables set for sbt are persisted and handled correctly after the project is reopened. The settings page File | Settings | Build, Execution, Deployment | Build Tools | sbt was redesigned for easier use, and a new Environment variables field was added so that you can now pass custom environment variables to the sbt-shell process.
ScalaDoc rendering
In this release, ScalaDoc’s Quick Documentation aligns more closely with Javadoc's. Annotations, keywords, and literals in displayed declarations are now highlighted based on the selected theme. The list of extended traits and classes is split into multiple lines if it exceeds the available space. Additionally, Scala 3 keywords are now supported in the documentation.
Fixed type inference errors
The new release comes with many fixes to invalid type inference in some complex or simply rare cases, such as when types have complicated bounds, when a sealed trait hierarchy might be unclear, or in complex pattern matching.
Zinc as the default compiler
In light of Zinc’s recent performance improvements, we’ve made it the default incremental compiler in v2023.2. This ensures comprehensive support for incremental compilation of new Scala 3 features, including inline methods.
Improved management of sources and target directories
Sub-folders of the target folder are no longer included automatically as sources unless they are marked as managed. This speeds up searching in projects that generate source code. Also, the IDE now provides better support for sbt-projectmatrix.
Profiler
Profiling features available from the Run tool window
Ultimate
In IntelliJ IDEA 2023.2 you can conveniently access the IntelliJ Profiler’s functionality right from the Run tool window.

Run / Debug
PreviousNext
Reactor Mono and Flux values evaluation
Ultimate
When debugging your reactive application, you can now easily evaluate values of watches and local variables for Mono and Flux types. The IDE now detects them during debugging sessions and provides a corresponding get or collectList link in the Variables view, which you can click to instantly compute reactive stream items. By default, the debugger fetches the first 100 items of Flux. You can configure this number in File | Settings | Languages & Frameworks | Reactive Streams.
Сontinuous testing for Gradle, Maven, and JPS projects
We have expanded the capabilities of the auto-testing functionality, making it fully compatible with the Maven, Gradle, and JPS build systems. We’ve also made it easier to activate continuous testing mode. To enable it, use the new Rerun Automatically button located in the Run/Debug tool window. Whenever your changes are saved, the tests will run automatically, providing immediate feedback on your code updates.
Inline breakpoints for return statements
IntelliJ IDEA now offers improved support for setting breakpoints directly at the return statement, similar to how it was already being done with lambda expressions. This improvement offers developers improved debugging precision and deeper code analysis, providing valuable insights into code behavior and return values. To set an inline breakpoint, simply right-click on the gutter next to the statement and select the return option.
Version control systems
Option to commit specific lines of code
IntelliJ IDEA 2023.2 introduces a highly anticipated feature to selectively commit specific parts of code chunks. To perform a partial commit, select the lines within a chunk and call Include these lines into commit from the context menu.

New inspection for detecting mismatching value types in YAML files
Ultimate
In IntelliJ IDEA 2023.2, we’ve introduced a new inspection to eliminate the so-called “Norway problem” and prevent the unintended misinterpretation of Boolean values in YAML files. When a list primarily consists of strings but contains a Boolean-like literal, IntelliJ IDEA will highlight this literal, indicating a potential inconsistency, and suggest adding quotes to it. If the list is mostly composed of Boolean-like literals (such as true, false, off, on, yes, or no), any literal that deviates from this pattern is highlighted as a possible error, although no specific quick-fixes are suggested in this scenario.
Support for editing AsyncAPI files
Ultimate
Working with the AsyncAPI specification format in IntelliJ IDEA is now much easier. The IDE supports schema validation functionality and provides code completion for references, the Endpoints view, and the Editor Preview pane.
Docker
Preview of files inside Docker image layers
It is now easy to access and preview the contents of a Docker image layer in the Services tool window. Select the image from the list, select Show layers, and click Analyze image for more information. This opens a list of the files stored in the layer, from which you can easily open the selected file in the editor by right-clicking on the file and clicking Open File (or Download File for binaries).
Set Docker container to run as a Before Launch task for run configurations
It is now possible to set a Docker run configuration to run before another configuration by designating it as a Before Launch task. The IDE will wait for the container that is currently running to become healthy, and then it will launch the next run configuration. To put a Docker run configuration in a queue, first create it and then add it to the relevant container via Modify options | Add before launch task | Run configuration.
Kubernetes
Support for multiple kubeconfig files within a single project
Ultimate
We have introduced a new feature that allows you to set up multiple kubeconfig files within a single project. This simplifies the experience of handling multiple clusters or working with environments on different clusters in the same project. To set the files up, go to File | Settings | Build, Execution, Deployment | Kubernetes.
Ability to view deployment logs
Ultimate
You can now view logs for deployments in Kubernetes clusters in the Services tool window. Right-click on Deployment in the tree and then select Follow Log or Download Log from the context menu.

Second, you can now see the server-side analysis results without leaving your IDE, right out of the box. Learn more about Qodana and its latest release in this blog post.
Database tools
Support for Redis Cluster
Ultimate
You can now connect to Redis Cluster and have the same feature set as with standalone Redis. When connecting to a cluster, jdbc:redis:cluster: must be entered before the desired URL. Choose the appropriate connection type to achieve this. If SSH tunneling is required for the connection to the cluster, then the hosts and ports for all nodes in the cluster should be indicated in the URL.
New UI for the schema migration dialog
Ultimate
For v2023.2, we’ve reworked the schema migration functionality. The main difference is that the same object is now placed on the same line in both parts of the dialog, making it easier to understand which objects are going to be added, removed, or changed in the target schema.
Time zone setting for the data editor
Ultimate
The Data Editor and Viewer settings page has a new Time zone field for setting the time zone in which the datetime value should be displayed.
