    • Customize external dependencies in the search scope - You can now set External Dependencies to be either included in the scope or excluded from it.
    • Quick access to recent projects on Microsoft Windows - Updated the support for Windows jump lists and made it possible to open your recent projects by right-clicking on the IntelliJ IDEA icon on the taskbar or the Start menu.
    • Improved accessibility - Added more labels to UI elements on the Welcome screen, in the Project Structure view and in the VCS log. These elements, as well as gutter icons, are now read out correctly when a screen reader is enabled.
    • Syncing high-contrast mode in Windows with the IDE theme - Your IDE will now automatically apply the high-contrast theme when you launch the IDE for the first time if you use the high-contrast mode on Windows.
  • Version control
    • Better Pull Requests support - Pull request creation now takes less time: just click the + icon in the Pull Requests view and fill in all the details. If you double-click on any file in the Files tab, the IDE will open the in-editor diff. You will also find support for pull request templates, which contain the description text for your pull requests.
    • Support for Git commit templates - Added support for Git commit templates. If you want to create a custom commit message, you can use a template and fill it in with the information you feel is important. The IDE will then display this text as an initial commit message.
    • Configure a profile for pre-commit inspections - Improved the ability to choose a code inspection profile before committing changes to VCS.
    • Get files from another branch - You can now get a file from another branch in the Compare with branch dialog.
    • Save to Shelf - The new Save to Shelf action allows you to copy your changes to the Shelf while keeping them in the local changes.
  • Editor
    • Font weight options - You can now fine-tune the weight of your main and bold font styles.
    • Maximize tabs in the split view - Whenever several tabs that split the editor vertically are open, you can double-click either of them to maximize the editor window for that specific tab. To bring the window back to its original size, simply double-click it again.
    • JSONPath support - Added support for JSONPath expressions with the Goessner or Jayway syntaxes.
    • JSON Lines support - Added support for the newline-delimited JSON Lines format, which is used for working with structured data and logs. The IDE will recognize .jsonl, .jslines, .ldjson, and .ndjson file types.
    • Profiler - Reworked the profiler UI. The Home window has become more informative and attaching a profiler to the process is now faster. Added two new actions that can be accessed by right-clicking on a running application:
      • Capture Memory Snapshot - For taking *.hprof snapshots of your applications
      • CPU and Memory Live Charts - Which opens a tab with visualization tools for tracking resource consumption.
  • Java
    • Added support for Java 16.
    • New inspections for data flow analysis - IntelliJ IDEA can now warn you when arrays are initialized with a negative size. It can also recognize the Arrays.copyOf() and Collection.toArray() methods. The IDE also supports methods for unboxing or converting integers, such as Integer.longValue and Byte.intValue.
    • Other new and improved inspections:
      • You can now avoid unnecessary casts by narrowing the for-each loop parameter type.
      • You can now simplify code syntax by swapping .filter() and .map() calls if the filter uses the same value as produced by the mapper. Updated the inspection that replaces StringBuffer with StringBuilder to cover more cases.
    • Formatting for chained builder methods - Added new formatting options for chained builder methods help improve their readability.

    • Context live templates - Added a solution for generating simple statements straight from the database explorer – live templates. You can add your own templates or edit the existing ones in the SQL node.
    • Straightforward actions - Simplified navigation: Go to declaration (Ctrl/Cmd+B) invoked on an object in SQL now takes you to the DDL, not to the database tree. Also added a shortcut for the Select in database tree action: Alt+Shift+B for Windows/Linux and Opt+Shift+B for Apple macOS.
    • Better sorting - Improved data sorting:
      • A new ORDER BY field works similar to the WHERE field (which was called Filter before): enter a working clause to have it applied to the query of the grid.
      • If you want to use sorting on the client side (which means IntelliJ IDEA will not rerun the query, but will sort the data within the current page instead), uncheck Sort via ORDER BY.
      • The sorting is not ‘stacked’ by default. If you click on the name of a column you want to use to sort data, the sorting based on other columns will be cleared.
    • Easy copy-paste of data sources - You can copy, cut, and paste data sources using the shortcuts: Ctrl/Cmd + C/V/X.
      • When you copy a data source, the XML is copied to the clipboard, which you can then share via a messenger. You can also use the Paste action to paste a piece of XML from somewhere else.
      • If you cut and paste a data source inside one project, it will just be moved, no password required. But the password is required in all other cases.
    • Edit data in MongoDB - Added a crucial feature for working with MongoDB: starting with this version, you can edit data in MongoDB collections. A statement preview is now also available.
      • Added the ability to change the type of a field from the UI. This can be done either from the context menu of the field or in the value editor.
  • Other
    • Android - IntelliJ IDEA now supports all Android Studio 4.1.1 updates.
    • Support for bnd-maven-plugin - You can now import OSGI facet settings from the bnd-maven-plugin.
