The search filter in the "Import/Export" wizard, as well as the "Show View" dialog has been extended to also support category names. On a match, all elements in the category are shown. This changes the previous behavior where only entries were matched and searching by a category would result in an empty tree.

After many years of stability we have reworked the light theme of Eclipse to follow more modern design principles, similar to other major IDEs:

1. Lightweight view tab design
2. Flat look - No use of 3D gradients
3. Views use a darker background color.

These improvement where published as a preview in the 4.33 release. The improvements are now integrated in the standared light theme.

Up to now they up, down, left and right arrow key have been displaye as UP, DOWN.. in the display of key bindings on windows.

This has now changed so that these are displayed as arrow smybols (just like it's e.g. done on macOS). This makes this display of key bindgins look nicer and also makes them much shorter.

This new system property allows to set the application name with which Eclipse is registered in the operating system. This option is helpful to distinguish and group Eclipse instances.

In the previous release, a preference to enable an improved, monitor- and resolution-specific UI scaling on Windows was introduced (see this news). The feature has been largely improved since then. The feature makes each window adapt its scaling to the monitor it is currently placed on in a sharp, resolution-specific way and without requiring the application to restart. When using multiple windows, each of them will adapt its scaling to the monitor it is placed on. When enabled, this new feature replaces the current, limited scaling support for high-resolution monitors, which initializes the application's window according to the scaling of the primary monitor at application startup and produces blurry scaling when moving the window to another monitor unless you restart the application.

To enable this feature, check the Monitor-specific UI scaling box on the Appearance preference page (Window > Preferences > General > Appearance), as shown in the image below. The feature is still under development, thus marked as experimental and disabled by default. We encourage users to explore this feature and share their feedback to help us improve the functionality.

The images below demonstrate the scaling behavior in an extract of an Eclipse application when moving the window from a primary monitor with 100% scaling to another monitor with 200% scaling, first having the feature disabled and second having it enabled.

Edge replaces Internet Explorer as the default browser instantiated by SWT. Internet Explorer is outdated and out of maintenance. It is replaced with the WebView2 engine used by Edge. Switching to this modern engine will ensure that use cases keep working or enables uses cases that are not working with Internet Explorer anymore or have never been working with it. As an example, if an Eclipse application is executed in dark mode, according CSS styling of web pages will be applied if embedded via:
@media (prefers-color-scheme: dark) { ... }

In consequence, every SWT- and Eclipse-based product will by default now create instances of the Browser class based on Edge when running on Windows. Some notable examples are the welcome page and help in Eclipse products as well as the Javadoc view and the element info popups.

Feedback: In case you experience any issues or limitations with the Edge browser implementation, please report them back in the umbrella issue (#1466).

In case you want to or need to still use Internet Explorer in your Eclipse product, you can:

• Switch to Internet Explorer for a complete product by setting the VM argument (for example in your eclipse.ini: -Dorg.eclipse.swt.browser.DefaultType=IE
• Programmatically create a single browser instance with Internet Explorer by passing the flag SWT.IE to the browser constructor
• Create a fragment for host plug-in org.eclipse.swt containing a class with qualified name org.eclipse.swt.browser.BrowserInitializer that sets the system property -Dorg.eclipse.swt.browser.DefaultType=IE in its static initializer.

The XPath support of Eclipse E4 (i.e. the Plug-in org.eclipse.e4.emf.xpath) has been reimplemented to be purely based on javax.xml.xpath.XPath provided by the Java standard library. This enabled the removal of Apache Commons JXPath as a dependency of the Eclipse SDK (and due to joint efforts even of the entire Eclipse Simultaneous Release).

Furthermore it has been determined that the XPathContext API provided by the org.eclipse.e4.emf.xpath Plug-in is mostly unused among all Plug-ins of the Eclipse Simultaneous Release. Therefore the entire org.eclipse.e4.emf.xpath Plug-in and all contained APIs have been marked as deprecated and for removal in a future release. As a replacement, to query an E4 model using XPath from code, one new method has been added:
EModelService.findMatchingElements(MApplicationElement searchRoot, String xPath, Class<T> clazz)
