• Added SWAPPED and PREDICTIVE bits to the contact-point flags.
• More checking of JNI return values in the glue code.
• Removed unnecessary exception checks from the glue code.
• Updated Android NDK to version "r29".

22.0.1

Bugfix: desktop ARM natives are stored at wrong paths in JARs

22.0.0

• Stopped deploying artifacts to GitHub.
• Stopped deploying Windows PDBs.
• Began deploying artifacts to MavenCentral with new artifact IDs: "Libbulletjme-Android", "Libbulletjme-MacOSX_ARM64", and so on.
• Began deploying natives with signatures and classifers, in JAR format (desktop) and AAR format (Android).
• Ended support for three 32-bit desktop platforms: Linux32, Linux_ARM32, and Windows32.
• Bugfix: copyPcoProperties() doesn't copy user indices
• Bugfix: logic error in CollisionShape.nativeMargin()
• Publicized the CollisionSpace.setLocalThreadPhysicsSpace() method so per-thread physics spaces can nulled and garbage collected.
• Added public method Quaternion.isValidQuaternion().
• Disallowed GImpact shapes with zero triangles.
• Modified PhysicsDumper to skip linear/angular factors that are 1.
• Enabled support for flexible page sizes on Android.
• Updated Android NDK to version "r27c".

21.2.1

• Changed the default setting for collision-shape contact filtering (from enabled to disabled) to address Minie issue 40. This change may cause unwanted behavior for rigid bodies in contact with a gimpact, heightfield, or mesh; see Minie issue 18 for details.
• Added the ConicalFrustum collision shape.
• Implemented actual-margin debug meshes for concave shapes with meshResolution == 2.
• Added 14 accessors for the native user indices of CollisionShape, MultiBody, and PhysicsCollisionObject.
• Added 5 other public methods:
  • Heightfield.countColumns()
  • Heightfield.countRows()
  • Heightfield.upAxis()
  • IndexedMesh.surfaceArea()
  • MyMath.area(Triangle)

21.1.0

• Bugfix: crash in processAllTriangles() when m_bvh==NULL (Minie issue 43)
• Bugfix: wrong inertia for a CustomConvexShape when mass != 1
• Added the SphericalSegment collision shape.
• Added the TestApp application for manual testing.
• Added 11 public methods:
  • BoundingValueHierarchy.copyAabb()
  • BoundingValueHierarchy.copyQuantization()
  • BoundingValueHierarchy.countLeafNodes()
  • BoundingValueHierarchy.countNodes()
  • BoundingValueHierarchy.countSubtreeHeaders()
  • BoundingValueHierarchy.escapeIndex()
  • BoundingValueHierarchy.isLeafNode()
  • BoundingValueHierarchy.partId()
  • BoundingValueHierarchy.setTraversalMode()
  • BoundingValueHierarchy.traversalMode()
  • BoundingValueHierarchy.triangleIndex()

21.0.0

• Made numerous breaking changes to the native API.
• Deleted the (deprecated) DebugMeshCallback class. (API change)
• Bugfix: JVM crash while serializing BoundingValueHierarchy (Minie issue 41)
• Added the new CollisionConfiguration class and related methods:
  • CollisionSpace.getConfiguration()
  • PhysicsDescriber.describe(CollisionConfiguration)
  • a 5-argument CollisionSpace constructor
  • a 4-argument PhysicsSoftSpace constructor
  • a pair of 5-argument PhysicsSpace constructors
• Added 2 other public methods:
  • BoundingValueHierarchy.isCompressed()
  • MeshCollisionShape.getBvh()
• Improved the performance of contact filtering by adding an early return from FilteredInteriorCountCallback.
• Began building Android binaries using OpenJDK 11 (with Android Gradle plugin v7.4.0 and NDK v23.1.7779620) instead of JDK 8 (with Android Gradle plugin v4.2.2 and NDK v21.3.6528147).
• Began using htons() to configure byte swapping when serializing and deserializing a BoundingValueHierarchy. (This would be a breaking change for big-endian platforms, if any were supported!)
• Updated the Bullet sources to match SHA1 id=e9c461b0 of the bullet3 project, to add a test for constraint pass in btMultiBody.cpp. (Thanks to Ian Chen)

20.2.0

  • MeshCollisionShape.getSubmesh()
  • MyMath.circle(double)
  • MyMath.circle(float)
• Updated VHACD v4 to version 4.1 .
• Added more detail to descriptions of GImpact and mesh shapes.
• Began building Android binaries on a xenial distro, since trusty is nearing its end of life.
