The latest version of sbt, a popular build tool for Scala and Java projects, has been released. sbt 1.9.1 includes several bug fixes and improvements, including better support for Scala 3 and JDK 17.

One of the notable changes in sbt 1.9.1 is the support for Scala 3. Previously known as Dotty, Scala 3 is a major update to the Scala programming language. With sbt 1.9.1, developers can easily build and test their Scala 3 projects.

Another improvement in sbt 1.9.1 is the support for JDK 17. As Java 17 was recently released, this update allows developers to use the latest version of Java with sbt.

sbt 1.9.1 also includes several bug fixes and performance improvements. For example, the sbt launcher has been updated to reduce memory usage and improve startup time. Additionally, the sbt server has been improved to reduce latency when running tasks.

Developers can upgrade to sbt 1.9.1 by updating their build configuration file. For example, for a project using sbt 1.5.5, the following line can be added to the build.sbt file:

sbtVersion := "1.9.1"

Overall, sbt 1.9.1 is a significant update that brings better support for Scala 3 and JDK 17, as well as several bug fixes and performance improvements. Developers using sbt should consider upgrading to take advantage of these improvements.
