The first release candidate for Apache NetBeans 26 has been released for testing, featuring numerous enhancements and corrections. The release encompasses updates for Gradle, Maven, Ant, Java, Swing Templates, OpenJDK hotspot tests, apidoc generation, renaming for permitted subclasses, and renaming for Java SE 25 for Tomcat, TomEE, and GlassFish. Furthermore, enhancements have been implemented in Java SE 25 for Tomcat, TomEE, and GlassFish, as well as in Java SE 11 for Jakarta EE 11.
The release encompasses corrections for the database properties directory, enhancements for port forwarding to OKE Pod, and the implementation of --also-make for run+debug as the default setting in Micronaut applications. The release also addresses issues with Java documentation, ensuring the use of the entire code body when creating a doc comment tree. The release additionally tackles performance scaling issues in the JS-embedder annotation scanner. The release encompasses enhancements for Java SE 25 applicable to Tomcat, TomEE, and GlassFish, as well as advancements for Jakarta EE 11.
The update encompasses a range of enhancements to the SemanticHighlighter, JsSemanticAnalyser, CSS, JS, versioning, editor, UI, platform, browser integration, language server protocol, LSP/Textmate, VSCode Extension, maintenance, and various other modifications. The update encompasses measures to prevent NPE in SemanticHighlighter, the integration of syntax coloring support for JavaScript vue files, the addition of support for container query length units, the resolution of issues related to the CSS revert property, and the facilitation of async generator methods. The update encompasses versioning, addresses bugs in the editor annotation options, modifies focus behavior upon closing the last editor in window mode, and facilitates the switching of previews for search results, refactoring, and bookmarks. The update encompasses code refinement and the management of nbres and nbresloc protocols within ImageUtilities. The update incorporates an adjustment to focus behavior, ensures a consistent dialog button order on MacOS, and introduces additional SVG icons. The update additionally resolves issues with the language server protocol, enabling the use of relative paths and class names as 'mainClass' settings in launch.json.
