Hi everyone. We have two patch releases sbt 1.2.7 and sbt 0.13.18.
How to upgrade
Change project/build.properties as follows:
The sbt launcher will automatically resolve the sbt JARs based on what's in project/build.properties.
However, if you want to resolve them faster, you should use the installers. zip, tgz, and msi installers contain all the JAR files so the resolution completes from the preloaded-local repository.
More fix for "Different extra API hashes" problem
People who have upgraded to sbt 1.2.4 or 1.2.6 noticed a weird error complaining about "Different extra API hashes":
[error] java.lang.RuntimeException: A fatal error happened in `SameAPI`: different extra api hashes for no traits! [error] `akka.util.OptionVal`: 0 [error] `akka.util.OptionVal`: 2116911007
Other sbt 1.2.7 fixes and enhancements
All active development has been on sbt 1, but I would like to annouce the end of sbt 0.13 public support effective today, and April, 2019 for Lightbend subscribers. sbt 0.13.18 will likely be one of the last 0.13.x releases.
sbt 1.2.7 was brought to you by 11 contributors according to git shortlog -sn --no-merges v1.2.1...v1.2.0 on sbt, zinc, librarymanagement, util, io, launcher-package, and website: Eugene Yokota, Dale Wijnand, Altern Egro, Antonio Cunei, Ethan Atkins, Fred Muya, Ignasi Marimon-Clos, Josh Soref, Kenji Yoshida (xuwei-k), Olli Helenius, and tripu. Thanks! Thanks Justin Kaeser, Jilen, and Kenji Yoshida (xuwei-k) for sbt 0.13.18!
