For the Clan fans, these files are formatted "Clan Name (IS Name)" rather that the standard "IS Name (Clan Name)" for those designs with two names. Simply unzip these and place them in your SSW folder. If you wish to avoid duplicates, you'll need to manually delete the files with the IS names first.
Update to bring 0.6.69 up to 0.6.70. This is NOT a standalone version, it is an update. You must have a previous version installed before applying this update. Simply unzip the contents and overwrite your old version.
A new Master `Mech file for SSW. Quite a few changes to bring it into line with data released via the MUL and other record sheets. Simply download the file and unzip it wherever you want, and then point to that location when SSW asks.
