## GWT 2.8.0 ist raus

21.10.2016 · [Christian Ullenboom](https://tutego.de/blog/javainsel/author/admin/)

Details zu den Änderungen unter . Toll ist die Unterstützung von Java 8.

- Started using ES6 Maps when available for HashMap/HashSet that yields up 3x performance improvements.
- Partial support for Java 8 standard library APIs (see below for full list).
- Source level set to Java 8.
- Static and default methods in interfaces aren’t visible to generators. If you want to take advantage of those Java-8isms, you’re encouraged to switch to an annotation processor. This could break existing build if an interface is changed to turn a non-default method into a default method.
- Emulate `java.io.UncheckedIOException`.
- Emulate `Optional` and its int, long, double variants.
- Emulate `Objects.requireNonNull()` with message `Supplier`.
- Fix Math.min/max(float/double) emulation behavior.
- Emulate `Character.isBmpCodePoint()`.
- Emulate `CharSequence.chars()`.
- Emulate `java.lang.SecurityException`.
- Emulate Java 8 API of
- `java.util.Arrays`,
- `java.util.ArrayDeque`,
- `java.math.BigInteger`,
- `java.util.BitSet`,
- `java.util.Comparator`,
- `java.util.function`,
- `java.util.Iterator`,
- `java.lang.Iterable`,
- `java.util.IntSummaryStatistics/LongSummaryStatistics/DoubleSummaryStatistics`
- `java.util.Collection/Lists/Queues`,
- `java.util.Map`,
- `java.util.logging.Logger`,
- `java.util.PrimitiveIterator`,
- `java.util.Spliterator`,
- `java.util.stream`,
- `java.util.StringJoiner`
