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:
sbt.version=1.2.7
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
sbt 1.2.7 hopefully fixes this problem this time. zinc#620 by @eed3si9n
Other sbt 1.2.7 fixes and enhancements
sbt 0.13.18
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.
