it depends how old your old saves are - for example, i've got some saves from like, well over a year or more ago, where he changed how some of the early game quests worked, so trying to load those saves, the script stuff doesn't match, and it messes up. putting your 'old saves' in the last version, and this version, won't help - they're still jacked up. some of those saves will still work - i've got stuff from around the police precinct invasion and on that still work, but most of the stuff before that's screwy.
so, you'd need to rego through the game and make 'cleaner' saves for the current iteration of programming - it will probably be the same from the last version, assuming no backtracking to change stuff again, but given it's not out, there's no talk about compatibility yet. again, saves from the last version are probably fine, but those really old saves, nope.
at the very least, the new version will have the improved scene gallery rather than just pictures, so, once we do go back and replay the whole game to unlock stuff (or just, there's a gallery unlocker), even if something like that happens again later, we've got the gallery now, so we won't need to go back and make like 40 separate saves for 40 scenes like a lot of rempy games without a good gallery.
