Even though my plan was to release a new unstable version after I have cleaned up interface issues due upping the resolution to 800×600. Athanasios at the dune2k forums requested for a new unstable release regardless.
Of course, with a big disclaimer I will fullfill that request. You can grab the latest revision (337) from the unstable releases page. Along with it I have updated that page so it describes more clear what kind of unstable releases will be coming.
As always you can let me know what you think.
