Go Weekly

Go 1.25 Release Candidate 1 — The final release of Go 1.25 isn’t till August, but the Go team is confident enough to issue the first RC now. The only language change is the removal of the notion of core types as explained by Robert Griesemer recently. There’s plenty going on behind the scenes, though, like the new experimental garbage collector and changes to both GOMAXPROCS and the generation of debugging information.

Why I'm Excited About Go for Agents — If you view agents as (mostly) stateless tasks running in a loop, then Go’s concurrency model and use of Context make the language nearly perfect for developing them. Plus, Go’s excellent profiling story means you’ll be able to chase down any memory or thread leaks.

🛠 Code & Tools

go-redis 9.10: The Official Redis Client for Go — A significant release for one big reason. Redis 8.0 was recently released and as well as becoming open source again, the popular data structure store now supports vector sets and vector similiarity search. My experiments with this feature have been very promising and go-redis now has experimental support for vector sets too. Main docs site.
