yah, for anyone with modified boards, the migration to 7.6 won't have a 'changed_files.txt' to rely on, since it is every one of them.
you'd have to compare your 7.5.7 modded to 7.5.7 stock and note those files you've changed, then manually merge them into the new scheme.
7.6 won't even be an 'upgrade' either. it will be an IMPORT... (every table name goes to lower case, utf-8 is standard etc... )
matter of fact, just doing the importer is a huge task right now.
there is no timeframe on 7.6.... i will resume it in the new year, but it's not a 'coupla weeks'.... it'll be a careful process, given time to do it right...
