No, at the former lemur exhibit they are building the new warthog exhibit (but viewing all the "new" exhibits I expect the worst... ). The hippo enclosure has been reduced a bit due the construction of the elephant dormitories. To separate the hippos from the dormitories they put metallic bars, but all of them are oxidated... 
The Aquarama and Madagascar exhibits are both closed since many months without any official explanation. The masterplan is stopped, but the zoo still shows to the visitors the container with all the renders, maps and videos explaining the masterplan. For a normal visitor seems that the zoo is improving the facilities, but those who often visit it is the opposite. The best thing to show this is what is happening at the sabana zone, especially with the elephants, or al the simple-wooden provisional exhibits.
