Given the high volume of posts on the main OMNeT++ discussion list, it is easy for important posts like announcements to get lost in the noise. Several members of the community have suggested that a low-traffic list reserved for just announcements of various kinds would serve the community well, which led to the creation of the new omnetpp-announcements list.
Anyone may post, not only the OMNeT++ core team. In particular, we invite authors/maintainers of various simulation models/frameworks to post about new models, or new versions of existing models. Other posts such as announcements about events, tutorials and other online content are also welcome.
