Lightbend’s tooling team announced the final release of sbt 1.0.0 on Thursday, August 11th.

This is a big deal as this release has been years in the making. According the the release, some of the highlights include:

• Zinc 1, a new incremental compiler - class-based name hashing which will speed up compilation time of Scala in large projects.
• zinc#304 - Overhaul of the Zinc internal API for good Scala integration with other build tools.
• #1911 - Adds logging of the neame of the different build.sbt (matching *.sbt) files used
• #3218 - Fixes restligeist macro for old operators
• #lm#92 - Adds new offline mode to the Ivy-based library management
