  @ul
    @li
      scalafmt will not hang anymore, not even for
      @lnk("deeply nested computer generated code", "https://github.com/scalameta/scalafmt/blob/124134dcd6a6c45d398d713ade266e071f4dc73c/core/src/test/scala/org/scalafmt/pathologicalcasestest.scala#l13").
      when scalafmt detects it's struggling to format a statement,
      it falls back to heuristics that return decent, but suboptimal, formatting
      output. if the heuristics still fail, scalafmt falls back to the
      original formatting of the code up until the next statement.
    @li
      spark, akka and the intellij scala plugin have been added to the
      test suite, which now runs on a total of 9.398 files from external
      projects. that's almost 8.000 more files than in 0.1.5! some key
      statistics from formatting all 9.398 files:

      @table
        @thead
          @tr
            @th
              computer
            @th
              75th percentile
            @th
              average
            @th
              max
        @tbody
          @tr
            @td
              2.5 ghz i7 macbook pro
            @td
              119ms
            @td
              112ms
            @td
              7.1s
          @tr
            @td
              travis ci (for fun)
            @td
              3.7s
            @td
              2.8s
            @td
              45.2s

      @p
        there is still a lot of work to do. the plan is to investigate
        the 90+ percentile cases in future releases as well as run
        more jmh benchmarks.

    @li
      for loops can now have multiple if guards in a row. for example:
      @example
        object forloopguards {
          for {
            x <- list(1, 2, 3)
            if (x != 1)
            if (x != 3)
          } yield x
        }
    @li
      fixed bugs where a newline would come after return keyword.
    @li
      fixed bugs where scalafmt would crash on the following if it exceeded
      the column limit.

      @hl.scala
        new foo with bar with kaz {}
    @li
      scalafmt no longer crashes when xml literal are used in infix
      applications.
    @li
      minor changes to select statement formatting.

@sect{0.1.5}
  @ul
    @li
      select chains are kept on a single line if they fit up to the last
      opening curly brace.

      @hl.scala
        // column          |
        // before
        List(1)
          .map { x =>
            x + 1
          }
        // after
        List(1).map { x =>
          x + 1
        }
    @li
      Really long sequences of infix applications (for example, string
      concatenations) don't hog anymore.
    @li
      Various small bug and speed improvements.
      For example, all files in
      @lnk("Fastparse", "https://github.com/lihaoyi/fastparse/"),
      @lnk("Scalding", "https://github.com/twitter/scalding") and
      @lnk("Goose", "https://github.com/GravityLabs/goose") that had
      problems with 0.1.4 format without issues on 0.1.5.
    @li
      Ramped up testing.
      Fastparse, Scalding and Goose
      have been added to the test suite, which now runs on 1405 files
      from external projects.
      The plan is to reach around 28.000 files in the coming 0.1.x releases,
      by including projects like
      @lnk("spark", "https://github.com/scalameta/scalafmt/issues/133"),
      @lnk("akka", "https://github.com/scalameta/scalafmt/issues/134") and
      @lnk("intellij-scala", "https://github.com/scalameta/scalafmt/issues/135").
    @li
      Made rather large internal refactorings, which shouldn't affect
      you as a user.
@sect{0.1.4}
  @ul
    @li
      @sect.ref{assumeStandardLibraryStripMargin}.
    @li
      @sect.ref{// format: off}.
    @li
      @lnk("Hanging behavior", "https://github.com/scalameta/scalafmt/issues/127").
    @li
      @lnk("Dozens of other small fixes", "https://github.com/scalameta/scalafmt/pull/128").

@sect{0.1.3}
  @ul
    @li
      @lnk("Better handling of type parameters", "https://github.com/scalameta/scalafmt/issues/117").
      Try it on your @lnk("craziest type signatures", "https://github.com/scalameta/scalafmt/blob/6c4e5165bcbfa3a932cc112d7e87a1e919fcaf99/core/src/test/resources/default/DefDef.stat#L63").
    @li
      @lnk("Array assignments are treated like regular call-site applications", "https://github.com/scalameta/scalafmt/issues/122").
    @li
      Commented out code remains un-indented (lines that start with
      @code("//") stay at indentation 0).
    @li
      Blank lines are only forced before top-level definitions and methods
      with docstrings.

      Thank you Sebastian!
