PUMAS v0.14 has been released. It allows for better optimisations of the
geometry navigation by providing extra info to the pumas_medium_cb. The
stepping algorithms was slightly tuned accordingly. In addition, a bug
has been corrected for non uniform magnetic fields as well.
Note that the signature of the pumas_medium_cb has changed. Please check the
docs. Details on the updated stepping mechanism can be found on the
release page. In case you have any problems with this update, you can
