Circular Multilateral Barter 1.8.5

We are pleased to announce that the next stable release of our
software for peer-to-peer barter exchange is now available.

Changes:
---More anti-DoS measures.

Most importantly, now DoS-attacks against the web-server are
never propagated to the database server. Therefore it is now
possible to have several web-servers, exposed to different
levels of DoS-attack thread, connected to the same database,
not interfering with each other. That is: An attack on one
of the web-servers will not overload the database, and
therefore will have no impact on the other web-servers.... read more
