I wrote a long-ish thing about implicit capabilities in the Cats ecosystem and shiny new lightweight support for user-defined (non-Throwable) error types on top of monads like IO: https://typelevel.org/blog/2025/09/02/custom-error-types.html

We just merged a potentially large fix to Metals that should help with cases were metals would just stop compilation. You can test it out with the latest snapshot to see if it helps with stability in your project. (1/2)

For those of you using Cats Effect to do real things, it would really mean a lot if you could take 3.6.0-RC1 for a spin together with Fs2 3.12.0-RC1 (doing them both is important!) sometime over the next week. We made significant under the hood changes and we want to make sure we don't break […]

Where are the #Scala frameworks?

Nice talk by Daniel from #RockTheJVM

Contrary to the complaints you might hear, the Scala community is largely satisfied:
49% of developers are happy, and 44% are rather happy with Scala.
And when it comes to future projects, over 88% would consider using Scala again ❤️. #ScalaSurvey

📯 Scala 3.6 is out!
💪 Improved syntax for givens, context bounds (SIP-64)
💪 Multiple, interleaved type parameter lists (SIP-47)
🧪 Experimental features, such as named tuples
🎉 and more; details: scala-lang.org/news/3.6.2
⚠️ use 3.6.2; ignore 3.6.1 and 3.6.0

Over all these years, I have used and tested many languages, but I still think that #scala is the right choice for me!
Not only at work, but also to solve puzzles like #AdventOfCode

I don’t celebrate Thanksgiving but thought this to be an opportune moment 2 thank Martin Odersky and the entire Scala community for a lang that gave me a decade+ long joy and fun in programming. Solved many hard problems working in Scala & truly the language scales w/ the complexity of the problem.
