Hi everyone. It’s time for a sbt 1.0.x hotfix.
I would also like to announce sbt 1.0.3, which is a hotfix to sbt 1.0.x series. This is a binary compatible release for sbt 1 focusing on bug fixes. sbt 1 is released under Semantic Versioning, and the plugins are expected to work for sbt 1.x series.

sbt.watch.mode JVM flag has been added with the following supported values:
polling: (default for macOS) poll the filesystem for changes (mechanism used in sbt 0.13).
nio(default for other platforms): use the NIO based
If you are experiencing long delays on a non-macOS machine then try adding
-Dsbt.watch.mode=polling to your sbt options.
A shoutout to Munich Scala User Group for organizing Build Workshop - keep our ecosystem in shape.
Organized by Lars Hupel (@larsr_h), Justin Kaeser (@ebenwert) IntelliJ Scala plugin dev, and Muki Seiler (@muuki88) sbt-native-packager dev, a bunch of people got together at codecentric AG (@codecentric) in München and hacked on builds to upgrade to sbt 1. This is awesome:
completed with at least 6 PRs for sbt 1.0 upgrades! https://t.co/7eGDyRsyFp— Justin Kaeser (@ebenwert) October 25, 2017
