What's Changed

Major Changes 🛠

• Speedup sample and allow specifying compile_kwargs by @ricardoV94 in #7578. This introduces several major changes related to step samplers:
  • internal uses of logp_dlogp_function now work with raveled inputs. External use will issue a warning unless ravel_inputs is specified explicitly. Eventually it will only be possible to use ravel_inputs=True.
  • Step samplers arguments besides vars must be passed by keyword
  • RaveledVars.point_map_info is now a 4-n tuple, with size introduced.
  • assign_step_method does not call instantiate_steppers, but returns arguments needed for the latter.
  • Allow passing compile_kwargs to sample which is then forwarded to the step samplers functions

Bugfixes 🪲
