Rodin Platform 3.5 Release Notes
What's New in Rodin 3.5?
Rodin 3.5 brings lexicographical variants and several bug fixes. It also upgrades the underlying Eclipse to 2020-06, which can be run by all modern Java Runtimes (Java 8 up to 13).
The new lexicographical variant feature means that from now on a machine can contain several variant elements, which are to be understood as a tuple combination (in order of appearance). For instance, if a machine contains the two variants V1 and V2 declared in that order, then a converging event must either decrease V1, or not modify V1 and decrease V2.
Please note that we only provide 64-bit binary versions of the Rodin platform.
Changes for plug-in developers
Rodin 3.5 is built on top of Eclipse 4.16 (2020-06), which requires Java 8, just as the previous versions.
There is no API change within Rodin Core.
Following to the introduction of lexicographical variants, a machine can now contain several variant elements. Moreover, variant elements now carry a label attribute. The Rodin tools contain a compatibility layer that allows to read existing machine containing a single unlabelled variant and present it with the new API (using the hardcoded label vrn available from the org.eventb.core.IVariant.DEFAULT_LABEL constant).
Installing
Downloading
Upgrading from a previous version of Rodin 3.x
TODO CHECK IS THIS IS TRUE
The only way to upgrade is to download the new platform. You may then point it to your usual workspace(s). This restriction is due to the Eclipse switch.
For those who are annoyed to install their Rodin plug-ins once more by downloading from the update site, it might be worth installing them directly from your older Rodin installation:
- run the new Rodin
- File > Import... > Install/From Existing Installation
- Point to your older Rodin installation
- Select the features you want to install
- Proceed with the Next button, the following is just as a usual install
Requirements - Compatibility
- Configurations supported (and for which binaries are provided)
- Linux 64-bit
- Windows 64-bit
- macOS 64-bit
- You need to have a 64-bit Java JRE (8 or later) installed on your computer. The Rodin application will not work with a previous version or with a 32-bit JRE.
- 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 functionalities, you need to install the Brave Sans Mono font on your system. You can download this font from the link here.
- Linux 64-bit:
- package 'libc6-amd64:i386' must be installed, in particular in order to run external prover binaries
- depending on the distribution, you could instead need these packages: lib32z1 lib32ncurses5 lib32bz2-1.0
- Windows 64-bit:
- Atelier B provers work more slowly; it can cause ML to not automatically discharge some sequents that it discharges on windows 32-bit, due to its timeout. A workaround is to download a custom profile: DefaultAuto_ML800, then Window > Preferences > Event-B > Sequent Prover > Auto/Post Tactic > Profiles (tab) > Import..., point to the downloaded file, 'Select All' profiles (there are 2), OK. Then in 'Auto/Post Tactic' tab, select 'Default Auto Tactic Profile (ML 800)' profile for auto-tactics. It is the same as the 'Default Auto Tactic Profile', except ML has a longer timeout (800 ms). You can of course change this timeout by editing the 'ML (800)' profile.
- We have not noticed this problem for Linux 64-bit, nor for other platforms; however if you do, the same workaround applies.
- macOS 64-bit:
The Rodin application is not notarized. This means that when you download it from SourceForge, macOS will quarantine the application and tell you that it is broken. Just run the command xattr -rc Rodin.app in a Terminal to remove the quarantine tag.

Known Issues
See known bugs on SourceForge.
Rodin is not notarized
Apple asks that all applications are notarized before they can be run since macOS Mojave. Unfortunately, we did not have time to put this in place for Rodin 3.5. We expect this to be solved for Rodin 3.6.
macOS in dark mode
See Bug 785.
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 ensure 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.
