Welcome to the Clojure Deref! This is a weekly link/news roundup for the Clojure ecosystem. (@ClojureDeref RSS)

From the core

This week we released Clojure 1.12.0-alpha4 which is mostly bug fixes to previously released 1.12.0-alpha features (mainly IDrop, add-lib, and We really appreciate all the feedback and bug reports on those things. In particular, one of the IDrop fixes this week was the result of tracking down a somewhat obscure crash with Sean Corfield - he patiently ran a lot of stuff and provided some key insight near the end as we tracked down the difference, which had to do with partition on non-integers! Anyways, that’s fixed. The add-libs and related changes cover some important ground too, but make sure that you are using the latest Clojure CLI - that is required for add-lib to work.

Work continues this week on functional interface adapters. We ran into a bit of a corner and took a step back to think a bit more broadly about what would be useful which redirect us slightly, still puzzling through that. I also did a bit more exploratory work on varargs support, and Fogus continues to work on the ability to use Java methods as IFns - we are trying to be careful there in combination with the functional interface adapter work so we don’t end up taking a Java functional interface, wrapping it as an IFn, and then adapting it back to the functional interface - we think we have a strategy to do that.

And as always, big thanks to Anton Fonarev for all the assistance on link aggregation!
