There are no new stable language features, but notable additions include HTTP/3 support in the HTTP Client API, AOT cache improvements for any garbage collector (Project Leyden), G1 GC throughput improvements, warnings for deep reflection on final fields, and removal of the Applet API. Preview features include primitive types in patterns (fourth preview), lazy constants (formerly stable values), structured concurrency, and PEM encoding/decoding. The Vector API continues as an incubator feature. IntelliJ IDEA 2026.1 supports all Java 26 features from day one, including new inspections, debugger improvements for virtual threads in structured concurrency, and tooling for lazy constants. A JetBrains contributor also added min/max default methods to java.util.Comparator in the JDK. ## Full article daily.dev links to this article rather than hosting it.
