Rodin Platform 3.5 Release Notes
Dedication to Ken Robinson
This release of the Rodin Platform is dedicated to the memory of Ken Robinson (University of New South Wales) who passed away the 5th of September 2020. Ken was a vibrant member of the Event-B community and an important user of the Rodin platform: he did not hesitate to complain loudly when the platform was not running as he expected. His regular feedback allowed us to greatly improve Rodin for the great good of the whole community. Ken was also the author of the Event-B Cheat Sheet available with the Rodin handbook.
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
If you run Rodin 3.1, 3.2, 3.3, or 3.4, then you can upgrade your Rodin Platform by clicking Help > Check for Updates, then select Rodin 3.5 in the popup window and accept the licence terms. Note that the upgrading process can take quite a long time.
Take care that Rodin 3.5 brings a new version of Eclipse. This means that once you have opened a workspace with Rodin 3.5, you will not be able to open it with a prior version of Rodin anymore. Please consider copying your workspace for Rodin 3.5 to avoid any disaster.
If you run Rodin 3.0 or prior, you cannot upgrade to 3.5. You need to download the platform from SourceForge and reinstall your external plugins.
Requirements - Compatibility
Supported operating systems
Rodin will work on the following operating systems
- macOS 64-bit
- Linux 64-bit
- Windows 64-bit
Java Runtime requirement
You need to have a 64-bit Java JRE (version 8 or later) installed on your computer. The Rodin application will not work with a previous version or with a 32-bit JRE.
macOS specific requirements
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.
The Atelier B provers (not part of Rodin Platform, but very useful) do not work on macOS Catalina and newer. This is because they use a 32-bit binary program.
Linux specific requirements
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 specific requirements
Atelier B provers may 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.
Math fonts
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.

Known Issues

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. See macOS requirements for a workaround.
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.
