Compressed BSA format support
Thanks to cc9cii's and Azdul's efforts OpenMW 0.46.0 will feature the native support for Oblivion/Fallout 3/Fallout New Vegas/Skyrim (2011) BSA format (v103 and v104), which is a step towards the support of loading the assets of these games and their mods. Since this BSA format is normally compressed, it's considerably smaller than the equivalent Morrowind BSA format file and can allow for making more compact asset libraries.
See MR !56 (merged).
Remark: this was previously not tracked and wasn't added to the changelog. I thought it would be neat to take the neat number of 5000 for such a notable addition.
