Does object.tagcache changed in new firmware version?

[buuuudzik]

You should not use tagcache anyway. It's main purpose is for display in the object list. If you are manipulating tags table directly then you should update tagcache by joining object tags using ", "

I must using it to properly sync objects between different LMs. So is this separator changed recently? And how can I check in script what is the firmware version (when I want support backward compatibilty)?
