We will be using this time to update Open CASCADE Technology collaborative development portal ( to a newer version, within which:

  • CMS version will be upgraded to the up-to-date version as well as its design will be tuned up, including mobile-friendliness of the website, its structure will be optimized and usability - improved;
  • User forum ( will be merged with contributors forum ( and since that time will be hosted on;
  • Single Sign-on (SSO) will be introduced, which will allow users to log in with a single login and password to any of our resources, including the use of their existing accounts as well as the use of GitHub and Google accounts;
  • Git Repository and Issue Tracker platforms will be also upgraded during this period of time.

We will do our best to ensure the smoothest transition we can and during maintenance all our resources should work in normal mode. However, we recommend all our users to postpone using our resources until the notice 'maintenance is over' is published.
