I'll check my CVS repository if the was such a version. I'll create a diff, including all changes since then - or a nerby version if that one shouldn't exist.
The file structure (directory layout) changed between 0.81 and 0.82
My version history therefore can't track changes beyond that borde, because moved files appear as new files
I've made a diff between the earliest 0.82 version and the current version of en.tab
This should include all changes, removeals and additions made in en.tab since then.
Yes, Simutrans includes an italian translation. It is fairly up to date, although the latest developments like the line management UI texts are missing AFAIK.
