### Fixes with compatibility implications
- Rolls back XML parsing workaround. See below.
### Improvements
- Discovered main classes are now sorted. [#1180][1180] by [@kretes][@kretes]
- Implemented a new mechanism of forking javac, whereby errors are captured. Also more likely to run in-process. [#1702][1702] by [@jsuereth][jsuereth]

## Project-level dependency exclusions
### Rolling back XML parsing workaround
sbt 0.13.7 implemented natural whitespace handling by switching `build.sbt` parsing to use Scala compiler, instead of blank line delimiting. We realized that some build definitions no longer parsed due to the difference in XML handling.
val a = <x/><y/>
val b = 0
At the time, we thought adding parentheses around XML nodes could work around this behavior. However, the workaround has caused [more issues][1738], and since then we have realized that this is a compiler issue [SI-9027][SI-9027], so we have decided to roll back our workaround. In the meantime, if you have consecutive XML elements in your build.sbt, encose them in `<xml:group>` tag, or parentheses.
val a = <xml:group><x/><y/></xml:group>
val b = 0
