The Turbine team has decided to do some actual software paleontology and do a release of the long standing Turbine 2.3.x component layer called "Stratum". This release is intended as a closure to replace all the alpha and beta versions floating around. There is no further development beyond the 1.0 version planned. Turbine Stratum is distributed as binary including all documentation and as a source distribution. The jar itself is also available through the ibiblio Maven repository.
