VirWOX issued a fix for the problem of purchasing 0 (zero) priced items which has been deployed to the grid, so that is working again.
Mono has been updated to version 4.0.3.20.
Code changes have been deployed to the statistics modules so resource usage in a region is displayed more accurately in the viewer Statistics panel (Shift + Control + 1 to display). In addition the network statistics is more accurate for managing the sims.
A number of other small fixes has been deployed to the servers.
