Scala is a strong statically typed general-purpose programming language that supports both object-oriented programming and functional programming. Designed to be concise, many of Scala’s design decisions are aimed to address criticisms of Java.

Only the latest 2.x and 3.x releases are actively developed. Those versions are named current releases.

A few older 2.x releases are also maintained with bug fixes and security support. Those releases are named maintenance releases and are maintained for a long time (because migration between two 2.x releases is difficult).

Scala 3 release policy

Starting with Scala 3.3, development is split into two lines called Scala Next (for newest and experimental features) and Scala LTS (only bug fixes, non-language changes and minor quality-of-life enhancements). LTS releases are released every two years and each LTS release is supported for at least three years.

JDK Compatibility

Scala’s primary platform is the Java Virtual Machine (JVM).
