Automatic notice of new localized version missing There…

Automatic notice of new localized version missing. There was standard behaviour, that users could upgrade quickly to the latest WordPress version and when localized version was ready and released, notice about new localized version appeared in administration. Do you remember this behaviour? But some users found that it was changed (in 3.5 or maybe 3.4) and when they upgrade to English version, they are not noticed about new Czech version in the future which is annoying. I tried it on some websites and it is true. I am not sure, if it is wanted change (but does not make sense for me) or bug (regression)?
