Highlights

  • Able to compile projects with jsinterop-base 1.0.0, elemental2 1.0.0, and
    jsinterop-annotations 2.0.0. With the exception of @JsAsync and @JsEnum, this
    brings GWT2 to be compatible across these tools with J2CL.

  • Added support for Java language levels 9, 10, and 11.

  • Officially, support is dropped for running the GWT compiler or server-side
    tooling on Java 7. The GWT distribution is still compiled to run on Java 7
    for this release, but no guarantees are made about whether or not this will
    work. Future versions will compile bytecode for Java 8+. The release was
    tested and found to work cross platform when run with Java 8, 11, and 14.

Deprecations

  • Elemental has been officially deprecated - it is still included in this
    release, but may not appear in future releases. Instead, we encourage the use
    of the Elemental2 libraries, which are compatible with both GWT2 and J2CL.
  • Removed NoSuchMethodException emulation.

Bug fixes

  • Fixes Arrays.binarySearch semantics for float[] and double[]
  • Adds Support multi-line messages in errors/exceptions
  • Adds shutdown hook in DiskCache to clean up temp files
  • Cache Gecko version to lower CPU usage on FireFox
  • Do not assume that "this" is always non null.
  • Updates globals for Firefox version 60.0.2, Chrome 66.0.3359.45
  • Fixes String.regionMatches.
  • Native JsMethods allowed to coexist with implementations with the same name.
  • Make sure lambdas box, unbox and insert erasure casts when necessary.
  • Negative zero treated properly in Double/Float.compare()

Miscellaneous

  • Updates CLDR to version 34.
  • Arrays now implement Cloneable
  • Link backing errors together with a cause attribute, start tracking
    suppressed errors in addition to the cause in underlying error object.
  • Add AtomicReference to gwt/emul.
  • Propagate script nonces via ScriptInjector
  • Add partial emulation for ExecutorService and ScheduledExecutorService
  • Emulate java.util.concurrent.Flow
  • Emulate javax.annotation{,.processing}.Generated
  • Make sure "goog.global" is $wnd if not defined.
  • Add when-linker-added element definition
  • Add Reader and StringReader emulation.
  • Remove GWT version check.
  • Do not show "unusable-by-js" warning for synthetic methods.
  • Update unmodifiableList to throw on Java8 methods.
  • Disable DataflowOptimizer by default and emit a warning when used
