Versioning localization sheets

We're using I2 in an application and we find that as we release new versions, we periodically need to create a new spreadsheet to avoid changing language in old versions of the app. One thing we've run into is the caching of localization is not version independent.

Let's say we have two versions of the app each using its own spreadsheet ("old App" uses "1st sheet", "new app" uses "2nd sheet").

The setup:
- Install "old app". User prefs are updated with "1st sheet" version and last updated timestamp
- continue to make changes to "1st sheet", all is fine
- start dev on "new app" and create "2nd sheet"
- make changes to "2nd sheet", all is fine
- Install "new app". User prefs are updated with "2nd sheet" version and last update, all is fine

The twist:
- Make a change to "1st sheet" and run "old app". User prefs are updated with "1st sheet" version and last updated
- Run "new app"
- The cache still points to "1st sheet" information because the timestamp and version are the "latest"
- It doesn't know that we're on a different sheet

The workaround:
- Make a change to every spread sheet in consecutive order to ensure the later ones have a later timestamp

The solution:
- You should probably cache the spreadsheet Id along with the version/time stamp so you can clear the cache when the sheet id is different from last cached.

Thanks so much for the quick response Frank! I'll check it out and let you know if I have any issues. Do you have a sense of when the next official release will be coming out?
