Rodin Platform 3.6 Release Notes

What's New in Rodin 3.6?

Rodin 3.6 brings several bug fixes. It also upgrades the underlying Eclipse to 2020-12, which can be run by Java 11 Runtimes.

Please note that we only provide 64-bit binary versions of the Rodin platform.

Changes for plug-in developers

Rodin 3.6 is built on top of Eclipse 4.18 (2020-12), which requires Java 11.

There is no API change within Rodin Core.

Upgrading from a previous version of Rodin 3.x

If you run Rodin 3.1, 3.2, 3.3, 3.4 or 3.5, then you can upgrade your Rodin Platform by clicking Help > Check for Updates, then select Rodin 3.6 in the popup window and accept the licence terms. Note that the upgrading process can take quite a long time.

Take care that Rodin 3.6 brings a new version of Eclipse. This means that once you have opened a workspace with Rodin 3.6, you will not be able to open it with a prior version of Rodin anymore. Please consider copying your workspace for Rodin 3.6 to avoid any disaster.

If you run Rodin 3.0 or prior, you cannot upgrade to 3.6. 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 11 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.

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.

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.
