+
+
+We are pleased to announce the release of Scala.js 0.6.33!
+
+This is mostly a bugfix release, including a fix for a bad interaction with React.js' development mode and the `jsdom` JS env.
+In addition, we have upgraded to the standard libraries of Scala 2.12.11 and 2.13.2.
+
+Read on for more details.
+
+<!--more-->
+
+## Getting started
+
+If you are new to Scala.js, head over to
+[the tutorial]({{ BASE_PATH }}/tutorial/).
+
+## Release notes
+
+If you use `.scala` build files in `project/` and are upgrading from Scala.js 0.6.22 or earlier, do read [the release notes of 0.6.23]({{ BASE_PATH }}/news/2018/05/22/announcing-scalajs-0.6.23/), which contain a source breaking change in that situation.
+
+If upgrading from Scala.js 0.6.14 or earlier, make sure to read [the release notes of 0.6.15]({{ BASE_PATH }}/news/2017/03/21/announcing-scalajs-0.6.15/), which contain important migration information.
+
+As a minor release, 0.6.33 is backward binary compatible with previous releases in the 0.6.x series.
+Libraries compiled with earlier versions can be used with 0.6.33 without change.
+0.6.33 is also forward binary compatible with 0.6.{29-32}, but not with earlier releases: libraries compiled with 0.6.33 cannot be used by projects using 0.6.{0-28}.
+
+Please report any issues [on GitHub](https://github.com/scala-js/scala-js/issues).
+
+## New warnings
+
+In Scala.js 0.6.33, the Scala.js compiler will start reporting warnings when trying to override `equals` and `hashCode` in a JS type (extending `js.Any`).
+For example:
+
+{% highlight scala %}
+class A extends js.Object {
+  override def hashCode(): Int = 1
+  override def equals(obj: Any): Boolean = false
+}
+{% endhighlight %}
+
+will report the following warnings:
+
+{% highlight none %}
+Test.scala:6: warning: Overriding hashCode in a JS class does not change its hash code.
+  To silence this warning, change the name of the method and optionally add @JSName("hashCode").
+  override def hashCode(): Int = 1
+               ^
+Test.scala:7: warning: Overriding equals in a JS class does not change how it is compared.
+  To silence this warning, change the name of the method and optionally add @JSName("equals").
+  override def equals(obj: Any): Boolean = false
+               ^
+{% endhighlight %}
+
+Overriding `equals` and `hashCode` never *worked*, in the sense that it would not affect `==` and `##`.
+The new warnings make it clear.
+
+## Bug fixes
+
+Among others, the following bugs have been fixed in 0.6.33:
+
+* [#4034](https://github.com/scala-js/scala-js/issues/4034) Incorrect result for `-x` when `x` is `+0.0`
+* [#3998](https://github.com/scala-js/scala-js/issues/3998) Self-types in non-native JS traits cause confusing error message
+* [#3458](https://github.com/scala-js/scala-js/issues/3458) Bad interactions in `JSDOMNodeJSEnv` error handling with React.js dev mode
+* [#3818](https://github.com/scala-js/scala-js/issues/3818) Linking error for `Future.never` from Scala 2.13
+* [#3939](https://github.com/scala-js/scala-js/issues/3939) Compile error on a method with `@JSName("finalize")` in a non-native JS class
