Announcements

This release includes a number of translations of consumers of the legacy RigidBodyTree simulator to the newer MultibodyPlant, including every example used by our MIT users.

A number of substitutes for what are now C++ standard library mechanisms have completed their voyage through the deprecation pipeline; we bid farewell to drake_optional, drake_variant, and the Spruce filesystem library in this release.

Breaking Changes

These are breaking changes that did not undergo a deprecation period.

  • Removed some hydroelastic property setter methods:
    • Remove MultibodyPlant::set_elastic_modulus (#12596)
    • Remove MultibodyPlant::set_hunt_crossley_dissipation (#12596)
    • We believe this API, although public, has no downstream users.
  • Hide filesystem.h from downstreams (#12686)
    • We believe this API, although public, has no downstream users.
  • Re-implement the uniformly random rotation to actually be uniform (#12562)
    • This has caused some problems for consumers: The existing behaviour, although wrong, was relied on by some downstream code.

Dynamical Systems

Notes

This release provides pre-compiled binaries named drake-20200212-{bionic|mac}.tar.gz. See Stable Releases for instructions on how to use them.

Drake binary releases incorporate a pre-compiled version of SNOPT as part of the Mathematical Program toolbox. Thanks to Philip E. Gill and Elizabeth Wong for their kind support.
