* Two tasks concerned the prover performance from the core platform: the addition of rewriting and inference rules, and the addition of a mechanism to allow the customization and the parametrization or combination of tactics. While the addition of rewriting and inference rules has always been a regular task to enhance the Rodin integrated prover during DEPLOY lifetime, a new way to manage tactics has been implemented. In fact, since Rodin 2.1, the user is able to define various types of tactic strategies called 'profiles' which could allow him to adapt the order of the basic tactics an discharge some particular proof obligations accordingly. Moreover, since Rodin 2.3, the user is able to combine and parametrize these profiles increasing even more the potential of such proving feature.

In an Event-B development, more than 60% of the time is spent on proofs. It has been a continuous aim to increase the number of automatically discharged proof obligations (POs), thus improving the capabilities of the integrated sequent prover through the addition of rewriting and inference rules. These rules were provided through tactics, or existing or newly created. These tactics were automatic, or manual, or sometimes both. Providing new proving rules, even if it sometimes does not increase directly the number of automatically discharged POs aims to help the user to interactively discharge them. Indeed, some proof steps are made easier from the use of specific rules thus making the user spare his time.
