READING

YAML as a valid Scala 3 code

Yes, it's possible!
Ionut G. Stan
ExecutionContext.parasitic and Friends

There's a lot of confusion around execution contexts and how they work in Scala. The description in Futures and Promises does a good job of explaining the concept of how Futures work, but does not explain what the difference is between ExecutionContext.global, ExecutionContext.parasitic, and ExecutionContext.opportunistic, and where and when you would want to use these.

Tapir contributors

chimney-java-collections module now contains conversions for Scala to/from Java primitives. Also: bidirectional conversions, renaming the subtype in sealed/enum conversions, enabling default values only for a specific type, and more!
Chimney contributors
caliban 2.8.0

This release brings a long-awaited feature: @oneOf inputs. There's also possibility to easily use tapir with impure effects such as Ox. The release also includes a few breaking changes that should impact a very low amount of users.
