- Cheetah is now vectorised. This means that you can run multiple simulations in parallel by passing a batch of beams and settings, resulting a number of interfaces being changed. For Cheetah developers this means that you now have to account for an arbitrary-dimensional tensor of most of the properties of you element, rather than a single value, vector or whatever else a property was before. (see #116, #157, #170, #172, #173, #198, #208, #213, #215, #218, #229, #233, #258, #265) (@jank324, @cr-xu, @hespe, @roussel-ryan)
- The fifth particle coordinate `s` is renamed to `tau`. Now Cheetah uses the canonical variables in phase space $(x,px=\frac{P_x}{p_0},y,py, \tau=c\Delta t, \delta=\Delta E/{p_0 c})$. In addition, the trailing "s" was removed from some beam property names (e.g. `beam.xs` becomes `beam.x`). (see #163) (@cr-xu)
- `Screen` no longer blocks the beam (by default). To return to old behaviour, set `Screen.is_blocking = True`. (see #208) (@jank324, @roussel-ryan)
- Rework the `Aperture` element. Now `ParticleBeam` has a `particle_survival` attribute that keeps track of the lost particles. The statistical beam parameters are calculated only w.r.t. surviving particles. Note that the `Aperture` breaks differentiability if activated. (see #268) (@cr-xu)
