Hi cf-dev,

Abacus was started in 2015 by IBM with SAP joining shortly after. Since several years SAP is the only contributor, as it used Abacus in production.

Most users do not find the project robust and cost effective solution. Several reasons for this are outlined in this blog. We started solving some of the problems as part of version 2, but in the meantime our focus as a company has shifted.

As a result of all this, there is no activity around the project for more than a year, so we moved Abacus to the attic to reach its end of life.

If this still is a topic you are interested in, please reach out to us by replying to this mail or contacting me directly.

Best regards,
Hristo Iliev
