Readers looking for technical details or a feature list will not find them in the current announcement.

A new essay examines how Clojure, the Lisp dialect on the JVM, holds up as large language models reshape software development. The piece weighs Clojure's simplicity, stable syntax and functional design against the way AI coding assistants are trained mostly on more mainstream languages, sparking debate among developers about the language's future relevance.

Developers are being reminded that most cryptographic code running in modern programs was written by someone else, usually in third-party libraries. A cryptography inventory that only lists lines in a project's own source misses these dependencies. The argument is that proper audits must name the actual module providing each cryptographic function, a point seen as increasingly important for fintech and security-sensitive software.

A clean-room, open-source reimplementation of Adobe Photoshop called Photocraft has appeared on GitHub, written entirely in Rust. The project aims to recreate Photoshop's functionality without using any of Adobe's code.
