If you've not yet read about the general changes in the 1.4 beta line, now is a good time to do so. It's expected that we'll stay in beta for the 1.4 line until the week of July 29th, when we'll do an official release called 1.5. A lot is different here, so we want to make sure and give this time to mature before we put this out to everyone.
This one is the second release of the day, and probably the last until Friday unless something drastic happens (tomorrow is a holiday here in the US).
This release has the remainder of the gameplay features that I'd wanted to get into the 1.4 line, but hadn't had time for before. Both of these features are heavily defensive-oriented.
The first lets you put garrisons in your military production buildings and your town centers, which makes the placement of these suddenly relevant. And it makes yet one more thing competing for your currency resource.
The second makes flowers actually useful now, by giving them the ability to add auto-heal on buildings in their towns. This again is quite useful if you're not wanting your structures destroyed (often you are). This isn't going to save you from the sorts of heavy-hitters who come over and stomp a building in one or two hits, but it will build your towns back up after they take some glancing blows, making it harder to wear down a well-defended town through accidental attrition from non-siege units.
Of course, both of these compete with existing things for your resources. The upgrades compete for your currency, and the flower gardens compete for your AP and the space in your town (and, to a lesser degree, pottery; but that's easier to come by, relatively speaking).
There are a couple of other fixes and tweaks in here, too.
More to come soon. Enjoy!
This is a standard update that you can download through the in-game updater itself, if you already have any version of the game. When you launch the game, you'll see the notice of the update having been found if you're connected to the Internet at the time.
