Java SE 13 maintains backward compatibility with previous versions of the Java platform, meaning that all previously written Java projects will function without changes when run under the new version. The ready-to-install builds of Java SE 13 (JDK, JRE, and Server JRE) <noindex><a rel=\"nofollow\" href=\"http:\/\/jdk.java.net\/13\">are prepared<\/a><\/noindex> for Linux (x86_64), Solaris, Windows, and macOS. The reference implementation developed under the OpenJDK project <noindex><a rel=\"nofollow\" href=\"http:\/\/openjdk.java.net\/projects\/jdk\/13\/\">Java 13<\/a><\/noindex> is fully open under the GPLv2 license with exceptions from GNU ClassPath, allowing dynamic linking with commercial products. <\/p>\n<p>Java SE 13 is categorized as a standard support release, with updates being issued until the next release. Java SE 11 should be used as the long-term support (LTS) branch, with updates available until 2026. The previous LTS branch, Java 8, will be supported until December 2020. The next LTS release is scheduled for September 2021. It's worth noting that starting with the Java 10 release, the project transitioned to a new development process featuring a shorter cycle for forming new releases. New functionality is now developed in a continuously updated master branch that includes ready changes, from which stabilization branches for new releases are branched off every six months. The release of Java 14 is planned for March next year, with preliminary builds already <noindex><a rel=\"nofollow\" href=\"http:\/\/jdk.java.net\/14\/\">are<\/a><\/noindex> available for testing.<\/p>\n<p>From <noindex><a rel=\"nofollow\" href=\"http:\/\/openjdk.java.net\/projects\/jdk\/13\/\">new features<\/a><\/noindex> <noindex><a rel=\"nofollow\" href=\"https:\/\/jdk.java.net\/13\/release-notes#newfeatures\">Java 13<\/a><\/noindex> <noindex><a rel=\"nofollow\" href=\"https:\/\/blogs.oracle.com\/java-platform-group\/the-arrival-of-java-13\">in<\/a><\/noindex> <noindex><a rel=\"nofollow\" href=\"https:\/\/www.oracle.com\/technetwork\/java\/javase\/13all-relnotes-5461743.html#NewFeature\">note<\/a><\/noindex>:<\/p>\n<ul>\n<li class=\"l\"> <noindex><a rel=\"nofollow\" href=\"http:\/\/openjdk.java.net\/jeps\/350\">Added<\/a><\/noindex> support for dynamically appending CDS (Class-Data Sharing) archives, enabling applications to share access to common classes. With CDS, common classes can be placed in a separate shared archive, speeding up application startup and reducing overhead. The new version adds tools for dynamically archiving classes once the application has completed execution. The classes placed in the archive include all classes loaded during the program's execution and related libraries that were not present in the originally provided base CDS archive;\n<li class=\"l\"> In the ZGC (Z Garbage Collector) <noindex><a rel=\"nofollow\" href=\"http:\/\/openjdk.java.net\/jeps\/351\">has added<\/a><\/noindex> supports returning unused memory to the operating system;\n<li class=\"l\"> <noindex><a rel=\"nofollow\" href=\"http:\/\/openjdk.java.net\/jeps\/353\">Deployed<\/a><\/noindex> A refined implementation of the Legacy Socket API (java.net.Socket and java.net.ServerSocket) that is easier to maintain and debug.
