Users will have more control over features they care about, according to a recent Microsoft blog post. However, these new settings are not yet enabled for Windows Insiders.

New overloads on TarFile.CreateFromDirectory accept a TarEntryFormat parameter, giving direct control over the archive format. Previously, CreateFromDirectory produced Pax archives. The new overloads support all four tar formats—Pax, Ustar, GNU, and V7—for compatibility with specific tools and environments.

While the codebase is fresh and grows fast under the umbrella of the local environment, we tend to rely on debugging tools, which were created specifically for that purpose. The app is half-baked, and the code is split open. We observe it through the lens of our IDE and with the speed of our brain. Everything is possible; we may pause execution for minutes, and the whole system is a white box - an open book for us.

Air, now free for MacOS with Linux and Windows versions coming soon, is an agentic development environment, or ADE, built on the idea of integrating the essential tools for managing coding agents into a single coherent experience. Serving as a single workspace where Claude Agent, Gemini CLI, Codex, and Junie CLI can work side-by-side, Air helps developers navigate a codebase and easily switch back and forth between different coding agents.

Tracy is compatible with Kotlin from version 2.0.0 and Java from version 17. Integrations can be made with SDKs from OpenAI, Anthropic, and Gemini. The library also works with common Kotlin/LLM stacks including OkHttp and Ktor clients, as well as OpenAI, Anthropic, and Gemini ones.

The headline runtime feature in this preview is Runtime Async, described as a major change to how asynchronous methods work in .NET. According to the release notes, since C# 5 introduced async/await, the compiler has been solely responsible for rewriting async methods into state machine structs that track progress across suspension points. With Runtime Async, the runtime itself now understands async methods as a first-class concept and takes over responsibility for suspending and resuming methods.

JEP 527, Post-Quantum Hybrid Key Exchange for TLS 1.3, has been elevated from Proposed to Target to Targeted for JDK 27. This JEP proposes to enhance the implementation of RFC 8446, Transport Layer Security (TLS) Protocol Version 1.3, using the Hybrid Key Exchange in TLS 1.3 specification, currently being drafted by the Internet Engineering Task Force (IETF) in conjunction with JEP 496, Quantum-Resistant Module-Lattice-Based Key Encapsulation Mechanism, delivered in JDK 24.

A study from Dimensional Research shows that 92 percent of the 2,000 respondents reported being concerned about Oracle Java pricing, up from 82 percent in the same survey last year. Those stating they were very concerned about the changes leapt from 19 percent in 2025 to 29 percent this year. In 2023, Oracle changed its Java SE subscription model, shifting from a per-user or per-processor basis to per-employee.

From the discussions in the Jakarta EE Platform call[s] the last couple of weeks, it looks like we won't see a release of Jakarta EE 12 on this side of summer (on the Northern Hemisphere at least). The reason is that since Jakarta EE 11 was delayed by a year, most of the vendors are currently working on their implementations.
