After a great work performed by the IT operational team team, CloudStack (the software used to manage CI slaves) has been upgraded to the 4.4.2 version. Since we do not have any idea about the slaves that are really used in the projects, automatic restart cannot be performed, and* you have to restart slaves manually*. The maintenance is not fully finished as it is not yet possible to create new slaves. We will keep you informed on this problem.
As well as the CloudStack upgrade, a new version of the portal has been deployed. It includes libraries update, some bug fixes and minor changes visible on the portal (better display of news, logs).
