Rodin Platform 2.2 Release Notes
From Event-B
What's New in Rodin 2.2?
- General Interface
- Improved general platform performance. The build time has been decreased by about 40% on average since Rodin 2.0.
- See: Rodin Performances
- Modelling
- TODO
- Proving
- New Tactics, such as Negation Normal Form, Generalized Modus Ponens, Case distinction from implication.
- Changes for plugin-developers
- Proof storage has evolved with backward compatibility: it is transparent for common proof access (getting the proof tree/skeleton). However, for a plug-in that would access proofs using directly the database - which is highly discouraged, please note that IPRProofRule.getElementName() does no more contain a reasoner id, but instead a reference to a IPRReasoner, a newly introduced proof element type. See Proof Dependencies and Reasoner Conflicts.
- Signature: optionally, a reasoner may now implement the interface ISignatureReasoner. It is designed for those whose behaviour evolves during a session. A signature represents a single reasoner behaviour. When present, the signature is stored in proofs. These proofs are invalidated when the signature changes (detected at build time).
- External plug-ins can now contribute to the "Refine" action which produces a new component from an existing one. It replaces the former non extensible actions Refine and Extend.
Requirements
- Configuration
- Only a 32-bit version of the Rodin platform is provided for PCs
- Only a 64-bit version of the Rodin platform is provided for MAC
- You need to have a Java JRE (6.0 or later) installed on your computer. The Rodin product will not work with a previous version.
- To enhance your proving experience, the eclipse font settings (size, aspect...) are available from the preferences (General > Appearance > Colors and Fonts > Rodin). These settings allow you to modify the properties set on the Event-B Keyboard Text Font which is used in many views of the Proving UI. However, to enjoy these functionnalities, you need to install the Brave Sans Mono font on your system. You can download this font from the link here.
- Linux: the internal browser does not work with xulrunner-2.0 (for instance, it causes the welcome page to display a link instead of a html page); xulrunner-1.9.x must be installed.
Installing
Upgrading from Rodin 2.1.x
Use rodin-2.2-repo.zip, check "contact all update sites" (because a new version of Eclipse is used).

- "Show only the latest versions of available software"
- "Hide items that are already installed"
- "Contact all update sites..."
- uncheck
- "Group items by category"
- check
- the central area should now list 5 entries
- select "Rodin Platform", click "Next"

Disclaimer
Since Rodin is continuously maintained, several unsoundness bugs which have been encountered were investigated and fixed. However, despite the total commitment of our teams to insure the soundness of the platform, some unexpected and unknown soundness issues could remain. We would be grateful if you would report these issues to the development mailing list.
