Need a handy list of the useful security enhancements in JDK 25? Look no further. https://social.ora.cl/6011AwAzz

There's still a bit of work to do, but I've just pushed out a release of my text to speech library with a new phonemizer and initial support for non-english languages. github.com/hcoles/voices #java

#JUnit 6.0.0 is released! ✨ Java 17 and Kotlin 2.2 baseline 🌄 JSpecify nullability annotations 🛫 Integrated JFR support 🚟 Kotlin suspend function support 🛑 Support for cancelling test execution ⏭️ New `--fail-fast` mode for ConsoleLauncher 🧹 Removal of deprecated APIs docs.junit.org/6.0.0/releas...

Some interesting @graalvm.org #native-image changes - "We are working on turning the native image generator into a native image itself and in this way completely disentangling it from the HotSpot VM. Together with Project Crema ..." - github.com/oracle/graal...

🎉 The Ktor @opentelemetry.io integration doc is now live - ktor.io/docs/server-... #kotlin #otel

The Ktor roadmap for 2025–26 is here! Here's what we'll be working on: 🔶 API docs (OpenAPI is already in preview) 🔶 WebRTC Client with a Multiplatform API 🔶 Integration with Koog, the @jetbrains.com framework for building AI agents Explore what’s next 👇 blog.jetbrains.com/kotlin/2025/...

Java 25 / JDK 25: Features since the previous long-term support (LTS) release: openjdk.org/projects/jdk... #Java25 #JDK25 #OpenJDK #Java

Awesome... JEP 517: HTTP/3 for the HTTP Client API has merged into the #JDK mainline - github.com/openjdk/jdk/...

📢 Kotlin DataFrame 1.0.0-Beta3 is out! This update brings Parquet and DuckDB support, better compile-time schema tracking via the Compiler Plugin, and a big refresh of docs and examples. Read the full release notes 👇 kotl.in/w2eq2c?utm_c...

Finally, it's happening #jvm #java #valhalla

They said Kotlin isn’t for AI. We rewrote our platform anyway. Now there’s Koog — a JVM-native AI framework for production. 🔥 Drama, lessons learned, and why nobody wants to touch Python anymore: medium.com/@vadim.brili... #AI #AIAgents #Python #Kotlin #Koog #Java #SoftwareEngineering #OpenSource

If for some reason you haven’t seen it yet, we released Koog — one of the most advanced frameworks for building AI agents! Targeting unmatched range of platforms: JVM backend, Android, iOS, JS, and WebAssembly #ai #java #kotlin #genai #llm #openai #android #ios #js github.com/JetBrains/koog

With Kotlin 2.2, a new default rule makes annotations land where you expect them to, reducing boilerplate and aligning with how frameworks handle annotations. 👀 IDEA helps to catch that with in-editor warnings and quick fixes 👇 jb.gg/1bptcn

🎯 JEP 517 proposed to target JDK 26 Title: HTTP/3 for the HTTP Client API Type: feature Component: core / net Release: 26 See openjdk.org/jeps/517

ok... Dark mode 🌙 is coming to JavaDoc in #JDK 26 - download.java.net/java/early_a... github.com/openjdk/jdk/...

🚀 The first tech preview of OpenAPI support in Ktor is here! You can now generate OpenAPI documentation for your existing Ktor apps with minimal setup and no code changes. 🧑‍💻 Try it out with our sample project. github.com/bjhham/open-...

At last! @gradle.com 9.1 (still rc1) offers a "native" way to visualize the task graph with `--task-graph` ! (Also now runs on jdk 25) docs.gradle.org/9.1.0-rc-1/r...

Use TouchID for sudo on macOS: - cd /etc/pam.d && cp sudo_local.template sudo_local - uncomment the line in sudo_local

First JDK 25 Release Candidate: mail.openjdk.org/pipermail/jd... Downloads: jdk.java.net/25/ #JDK25 #Java25 #OpenJDK #TestItNow

We are working on a new big project for @graalvm.org — Project Crema: github.com/oracle/graal.... It will lift Native Image's default closed-world assumption by allowing dynamic loading and execution of classes at run time. Stay tuned for updates!

AOT Method Profiling JEP status has changed to candidate. openjdk.org/jeps/515 In my latest benchmark with Spring Petclinic, it allows to speedup the warmup compared to the regular JIT (red line versus blue one). Stabilized peak performance is currently slightly lower, but hopefully will be fixed.

Seems like #kotlin #ktor 3.2.0 will get UnixDomainSocket support for the CIO engine (Server and Client) 👏- github.com/ktorio/ktor/...

New JEP: Ahead-of-Time Command-Line Ergonomics Very nice to streamline how to create an AOT cache for your application. openjdk.org/jeps/514

Wow, LINQ for #Kotlin Multiplatform! github.com/ExoQuery/Exo.... This looks really nice, especially coming from the developer of zio-quill (LINQ in Scala) 🤯.

A taste what is already delivered and what is coming to JDKs with Project Leyden. The warmup curve for javac compile tasks clearly improve the further you go into the AOT woods.

We just integrated a performance improvement to Java String that will provide a ~10x performance boost in some applications where Strings are used as keys and where the associated values are constant foldable. This will make JDK 25 faster. github.com/openjdk/jdk/...

To better support virtual threads, JDK 25 increases the max hold count for ReentrantRWLock from 65K to Integer.MAX_VALUE (2.14 B) for improved scalability #jvm - github.com/openjdk/jdk/...

Our "javac on #WebAssembly" demo (and code!) for #WasmIO25 is up on GitHub in case you want to play with the new Wasm backend for @graalvm.org! 🚀 More details to follow soon! graalvm.github.io/graalvm-demo...

Probably the most impressive and exciting talk I have seen in years! Congrats to @fniephaus.com and Patrick Ziegler for their #wasmio presentation and work on @graalvm.org starting to compile Java applications to WasmGC. Kudos to @thomaswue.dev too.

🚀 Kotlin 2.1.20 is here! 🚀 This release brings powerful new features and improvements: ✨ K2 support for kapt and Lombok plugins 🔗 Common atomic types and improved UUIDs in stdlib ⏱️ Native time-tracking API ⚡ New inlining optimizations in Kotlin/Native Learn more: kotl.in/f959fd

Build an off-site NAS with a Raspberry Pi and LTE and put it on your tailnet, following this new tutorial from XDA Developers. Perfect way to celebrate Pi Day!

Nice... It seems there is a new Gradle plugin for AOT compiling WASM to class files using Chicory AOT compiler github.com/illarionov/w... #kotlin #java #gradle

github.com/openjdk/jdk/... Another nice improvement from @douglea.bsky.social - "Improve performance of delayed task handling . This speeds up some Loom operations by almost an order of magnitude (and similarly for CompletableFuture). 🤯 #jvm

github.com/roastedroot/... - A pure #java SQLite JDBC driver AOT compiled from c -> #WASM -> JVM Bytecode using chicory.dev AOT build time compiler. This opens the door for many tools and libraries to be easily ported to the JVM with no native dependencies..amazing 🤯

Byte Buddy 1.16.0 now integrates the Java Class File API and is therefore compatible with any future JDK that retains its instruction set, without activating the experimental flag. github.com/raphw/byte-b...

"We are testing out ZGC in a Xmx975G #JVM" 😱 ... I know ZGC can handle TB of heap sizes, but this is the first time I've seen someone use it. mail.openjdk.org/pipermail/zg... #java

Like 98% compute/bandwidth is bare metal. The cloud is great for small projects (costs are low) and highly profitable projects (costs matter less). But it fails projects that need to scale as efficiently as possible. Moving Bluesky to bare metal reduced costs by 10-100x and saved many millions.

Leetcode interviews are totally unrepresentative! In a leetcode interview, your performance is judged on work that's easy to assess rather than the actual value you would bring to the role, whereas once you're in a real job, your performance is judged on...

@thomaswue.dev I know @graalvm.org has a lot in the pipeline, but are there plans to improve cross-compilation in nesr future? This is especially important for those who can't use GH Actions for builds. Enabling builds for both AArch64 and AMD64 on the same host would be a significant improvement

We just merged the current status of the upcoming JDWP support for @graalvm.org Native Image! 🥳 This will soon provide developers with the same debugging experience they are used to in Java, but for native images! Stay tuned for more details. github.com/oracle/graal...

But with Maven 4 there's an SPI that allows users to user different POM syntaxes, see Maven Hocon Extension as an example (github.com/apache/maven...). 2/2

Nice, @jetbrains.com has released an MCP (Model Context Protocol) @kotlinlang.org client and server sdk github.com/JetBrains/mc... It's great to see Kotlin ecosystem is building important tools and libraries for AI development.
