+
+
+We are pleased to announce the release of Scala.js 1.5.1!
+
+This release mostly contains additions and improvements in the JDK libraries.
+In particular, several APIs involving floating point numbers have been fixed, from parsing to bit manipulation to formatting.
+
+Read on for more details.
+
+<!--more-->
+
+## Getting started
+
+If you are new to Scala.js, head over to [the tutorial]({{ BASE_PATH }}/tutorial/).
+
+If you need help with anything related to Scala.js, you may find our community [on Gitter](https://gitter.im/scala-js/scala-js) and [on Stack Overflow](https://stackoverflow.com/questions/tagged/scala.js).
+
+Bug reports can be filed [on GitHub](https://github.com/scala-js/scala-js/issues).
+
+## Release notes
+
+If upgrading from Scala.js 0.6.x, make sure to read [the release notes of Scala.js 1.0.0]({{ BASE_PATH }}/news/2020/02/25/announcing-scalajs-1.0.0/) first, as they contain a host of important information, including breaking changes.
+
+This is a **patch** release:
+
+* It is backward binary compatible with all earlier versions in the 1.x series: libraries compiled with 1.0.x through 1.5.0 can be used with 1.5.1 without change.
+* It is forward binary compatible with 1.5.0: libraries compiled with 1.5.1 can be used with 1.5.0 without change.
+* It is backward source compatible with 1.5.0: source code that used to compile with 1.5.0 should compile as is when upgrading to 1.5.1.
+
+In addition, like Scala.js 1.5.0:
+
+* It is *not* forward binary compatible with 1.4.x: libraries compiled with 1.5.1 cannot be used with 1.4.x or earlier.
+* It is *not* entirely backward source compatible with 1.4.x: it is not guaranteed that a codebase will compile *as is* when upgrading from 1.4.x or earlier (in particular in the presence of `-Xfatal-warnings`).
+
+As a reminder, libraries compiled with 0.6.x cannot be used with Scala.js 1.x; they must be republished with 1.x first.
+
+## Fixes with compatibility concerns
+
+The `%e`, `%f` and `%g` conversions in `java.util.Formatter`---also used by `String.format` and the `f"..."` interpolator---have been fixed to match their specification on the JVM.
+
+This may break tests that rely on the specific string output of formatting numbers.
+
+## Miscellaneous
+
+### New JDK APIs
+
+This release contains some improvements in the JDK APIs that we support:
+
+New interfaces:
+
+* All the remaining functional interfaces in `java.util.function.*`
+
+New methods:
+
+* `java.util.concurrent.ConcurrentHashMap.keySet(mappedValue: V)`
+* `java.util.concurrent.ConcurrentHashMap.newKeySet()` and `newKeySet(initialCapacity: Int)`
+
+Methods with fixed or improved behavior:
+
+* `java.util.Formatter` and derivatives (such as `String.format`) now support:
+  * `java.math.BigDecimal` arguments with the `%e`, `%f` and `%g` conversions (in addition to fixing `Float`s and `Double`s, as mentioned above)
+  * The `%a` conversion
+* `parseFloat` and `parseDouble` are now accurate to 0.5 ULP, as specified
+
+## Bug fixes
+
+Among others, the following bugs have been fixed in 1.5.0:
+
+* [#4434](https://github.com/scala-js/scala-js/issues/4434) `java.lang.Class.getSimpleName()` returns bad results for local classes
+* [#4452](https://github.com/scala-js/scala-js/issues/4452) Overloading in JS classes incorrectly forwards vararg parameters
+* [#3706](https://github.com/scala-js/scala-js/issues/3706) `j.m.BigDecimal.divideToIntegralValue(bi, MathContext)` returns value with bogus internal `_precision`
+* [#4035](https://github.com/scala-js/scala-js/issues/4035) `j.l.Float.parseFloat`'s result is 1 ULP off of the best approximation in some cases
+* [#4431](https://github.com/scala-js/scala-js/issues/4431) `j.l.Double.parseDouble` can be 1 ULP off for hexadecimal parsing
+* [#4432](https://github.com/scala-js/scala-js/issues/4432) `j.l.Math.ulp()` returns wrong results for negative values
+* [#4433](https://github.com/scala-js/scala-js/issues/4433) `doubleToLongBitsPolyfill(4.450147717014403e-308)` is incorrect
+* [#4395](https://github.com/scala-js/scala-js/issues/4395) `ConcurrentHashMap.KeySetView.toString` should print elements
