Nearly four years have passed since the 0.9.x releases, and almost all of the code has been rewritten, so the changes are various and many.
See [Drake v0.10.0 release notes](https://drake.mit.edu/release_notes/v0.10.0.html).
Drake binary releases incorporate a pre-compiled version of [SNOPT](https://ccom.ucsd.edu/~optimizers/solvers/snopt/) as part of the [Mathematical Program toolbox](https://drake.mit.edu/doxygen_cxx/group__solvers.html). Thanks to Philip E. Gill and Elizabeth Wong for their kind support.
