A non-production release, for development and testing only, not intended to be used in any product. Largely untested, without complete/reliable documentation, and without SDK support. Vital features may be missing. The feature set, API, and serialization format might change before the next release.

Changes relative to v3.4.0-stable:

• Potential breaking changes:

  • explicitly requires Java 8 or higher (issue #1661)
  • deleted the Weights class, which was deprecated in 3.4 (issue #1620, PR #1632)
  • changed the semantics of FastMath.sphericalToCartesianZ() (issue #1349, PR #1573)
  • protected the no-arg constructor of TransformTrack (PR #1531)

• New features:

  • determine the maximum supported width for lines (issue #1555, PR #1643)
  • support for additional compressed texture formats (issue #1619, PR #1621)
  • texture flipping for certain RGTC formats (PR #1629)
  • added getNbMorphTargets(), setKeyframesWeight(), and setNbMorphTargets() to the MorphTrack class (PR #1608)
  • made getOffsetTransform() and getAttachmentsNode() accessible to subclasses of Joint (PR #1536)
  • distinguish ARM macOS/Windows from other platforms (issue #1528, PR #1530)

• Bugs and defects addressed:

  • crashes while deleting native objects (issue #1614, PR #1617)
  • incorrect cursor position on macOS with Retina (issue #893, PR #1607)
  • can't recover from a disconnected audio device (PR #1593)
  • Android devices can't load assets whose names start with "/" (issue #352, PR #1577)
  • incorrect VirtualIndexBuffer for a LineLoop mesh (issue #1603, PR #1605)
  • sphericalToCartesianZ() doesn't reverse cartesianZToSpherical() (issue #1349, PR #1573)
  • assertion failure while loading a valid glTF model (issue #1089, PR #1608)
  • null-pointer exceptions while loading erroneous glTF models:
    • in GltfLoader.findChildren() (PR #1471)
    • in SkinningControl.getAttachmentsNode() (issue #1612, PR #1639)
  • cryptic crash when more than 16 textures are used (issue #37, PR #1574)
  • fromJmeKeyCode() returns garbage for unknown keys (issue #1596, PR #1638)
  • serialization bugs:
    • CartoonEdgeFilter class (issue #1640, PR #1647)
    • ShaderNodeVariable class (PR #1585)
    • Torus class (PR #1586)
  • typos in logger/exception messages (PR #1584, 3beca2b4)

• General improvements:

  • faster asset loading:
    • of AWT-based texture assets (PR #1613)
    • on Android devices (issue #1622, PR #1627)
  • faster writing of MJPEG files (PR #1592)
  • javadoc (issue #1648; PRs #1581, #1599, #1620, #1642, #1646, and #1651; 4db02fae, 8075eeb5, ac8696e, and f40f21a5)
  • examples and tests (issues #1290, #1630; PRs #1570, #1594, #1610, #1631, and #1635; 7c5fe46c and 9d8bd88)
