Win Merge shows now change in any of the files nor added/removed files. So I advice you to keep you current version, 'cause it's more likely that you are going to break something than fix anything. At least the support is now officially to 126.96.36.199. Albeit the support group is right, there is a huge security flaw on it, so upgrading to 188.8.131.52rc1 is advisable. In my case the theme works well enough w/ 184.108.40.206c1, I haven't identified anything broken related to upgrade.
