I have repeatedly encountered people asking whether some functionality is available, that was in v1 but is not yet in v2. We should compile a list of those functionalities and display it prominently, so that people can decide whether they already want to make the switch.
Discovering that some functionality does not exist after you already invested some effort into porting code can be very disappointing, so I think this is important to have.

Please add the things you are aware of in this issue. From a quick comparison of the docs, I see

• Sensitivity: functionality from the sensitivity module
• MCMC (discontinued): mcmc module, this functionality will probably be covered by a PyMC wrapper in the future.
• c2st metric
• from the simulation module: TwoLevelGenerativeModel, TwoLevelPrior
• networks: EvidentialNetwork, PMPNetwork

I know there are future plans to cover some of them in a more general setting, but I think it would be great to inform users up front what they are getting and not getting in the new version.

@stefanradev93 @paul-buerkner @LarsKue It would be great if you could complete the list, of give a go when you consider it complete.
