This single server distribution is both Linux and Windows compatible. The v0.5 release includes 22 maps, the only "vanilla" map included in v0.5 is Gulf of Oman (which has had some.. "optomisations" for Project Reality). You will need to revise the map list to your liking. Server admins should completely blow away their previous Project Reality server installations. ABR enabled servers will require a restart after being updated to v0.5. This release should also be 100% compatible with the latest release of the BF2CC server administration tool.
