- sbt 0.12 style `Build` trait that was deprecated in sbt 0.13.12, is removed. Please [migrate to build.sbt](http://www.scala-sbt.org/0.13/docs/Migrating-from-sbt-012x.html#Migrating+from+the+Build+trait). Auto plugins and `Build` trait do not work well together, and its feature is now largely subsumed by multi-project build.sbt.
|
||||
- sbt 0.12 style `Project(...)` constructor is restricted down to two parameters. This is because `settings` parameter does not work well with Auto Plugins. Use `project` instead.
|
||||
- sbt 0.12 style key dependency operators `<<=`, `<+=`, `<++=` are removed. Please [migrate to :=, +=, and ++=](http://www.scala-sbt.org/0.13/docs/Migrating-from-sbt-012x.html#Migrating+simple+expressions). These operators have been sources of confusion for many users, and have long been removed from 0.13 docs, and have been formally deprecated since sbt 0.13.13.
|
||||
- sbt 0.12 style tuple enrichement DSL, which was deprecated in sbt 0.13.13, is opt-in under `sbt.TupleSyntax`. [#2762][2762]/[#3291][3291] by [@dwijnand][@dwijnand]
|
||||
- Zinc 1 drops support for Scala 2.9 and earlier. Scala 2.10 must use 2.10.2 and above. Scala 2.11 must use 2.11.2 and above. (latest patch releases are recommended)
|
||||
- `config("tooling")` must be directly assigned to a *capitalized* `val`, like `val Tooling = config("tooling")`. This captures the lhs identifier into the configuration so we can use it from the shell later.
|
||||
- Changes `publishTo` and `otherResolvers` from SettingKeys to TaskKeys. [#2059][2059]/[#2662][2662] by [@dwijnand][@dwijnand]

- sbt 1.0 renames `Global` as scope component to `Zero` to disambiguate from `GlobalScope`. [@eed3si9n][@eed3si9n]
|
||||
- sbt 1.0 uses `ConfigRef` in places where `String` was used to reference configuration, such as `update.value.configuration(...)`. Pass in `Configuration`, which implicitly converts to `ConfigRef`.
|
||||
- Changes `sourceArtifactTypes` and `docArtifactTypes` from `Set[String]` to `Seq[String]` settings.
|

- `Command.process(..)` is removed. Use `"cmd" :: state`.

- Replace cross building support with sbt-doge. This allows builds with projects that have multiple different combinations of cross scala versions to be cross built correctly. The behaviour of ++ is changed so that it only updates the Scala version of projects that support that Scala version, but the Scala version can be post fixed with ! to force it to change for all projects. A -v argument has been added that prints verbose information about which projects are having their settings changed along with their cross scala versions. [#2613][2613] by [@jroper][@jroper]

Another related feature that was added is the `bgRun` task which, for example, enables a server process to be run in the background while you run tests against it.
|

|

### Event logging
|
||||
|
||||
sbt 1.0 introduces event logging implemented using Log4J 2 and sjson-new.
|
||||
In addition to the regular String-based logging, you can now send case classes and Contraband-generated pseudo case classes to the logger:
|
||||
|
||||
def registerStringCodec[A: ShowLines: TypeTag]: Unit = ...
|
||||
final def debugEvent[A: JsonFormat: TypeTag](event: => A): Unit = logEvent(Level.Debug, event)
|
||||
final def infoEvent[A: JsonFormat: TypeTag](event: => A): Unit = logEvent(Level.Info, event)
|
||||
final def warnEvent[A: JsonFormat: TypeTag](event: => A): Unit = logEvent(Level.Warn, event)
|
||||
final def errorEvent[A: JsonFormat: TypeTag](event: => A): Unit = logEvent(Level.Error, event)
|
||||
|
||||
Various events such as `[success]` message are sent internally via event logging.
|
||||
We are hoping that this mechanism can be used in conjunction with server so plugins and compilers can publish JSON events.
|
||||
|
||||
Since the logger uses Log4J 2 internally, we now provide SLF4J binding.
|
||||
|
||||
#### Static validation of build.sbt
|
||||
|
||||
sbt 1.0 prohibits `.value` calls inside the bodies of if expressions and anonymous functions in a task, `@sbtUnchecked` annotation can be used to override the check.

### Changes with compatibility implications

- Moves the old, sbt 0.10 tuple enrichement DSL, which was deprecated in sbt 0.13.13, out of implicit scope and
