undocumented v 1.03 feature: attacking the besieger has changed significantly

[Slaists]

I believe, this important change was not advertised in the originial CA post.

Before 1.03, if an army (even a single unit) attacked an army besieging a city, the whole garrison jumped into the battle as reinforcements. Post 1.03 this is no longer happening. Only the attacking army and the besieger go to battle. The garrison stays in the city.

So, this would mean that continuing the siege would finaly have a strategical advantage over assaulting.
