Peter writes to oss4lib-discuss: "Avanti version 0.4 has been released.� It is available at the Avanti project website along with documentation that can be perused online... Version 0.4 is a partial implementation of a library system and as such is not suitable for production use.� Rather, it is a reference version that defines the essential elements and architecture of the system, setting the stage for future development through version 1.0.� It is at the vanguard of what is expected to be a fairly rapid period of development toward a simple but functionally complete OPAC and circulation system in version 0.5.� This is tentatively expected some time around January 2002."
