As seen here.

scala> class A { @deprecated("foo") def a = 1 }
warning: there were 1 deprecation warnings; re-run with -deprecation for details
defined class A

scala> :warnings
<console>:7: warning: @deprecated now takes two arguments; see the scaladoc.
       class A { @deprecated("foo") def a = 1 }
                  ^

scala> val x = 5 toString
warning: there were 1 feature warnings; re-run with -feature for details
x: String = 5

scala> :warnings
<console>:7: warning: postfix operator toString should be enabled
by making the implicit value language.postfixOps visible.
This can be achieved by adding the import clause 'import language.postfixOps'
or by setting the compiler option -language:postfixOps.
See the Scala docs for value scala.language.postfixOps for a discussion
why the feature should be explicitly enabled.
       val x = 5 toString
                 ^
