The leopard may have arrived after you visited, but what I would be interested in is if you remember the enclosure? It is two rather large cages, one had three pumas and the other this Indian leopard, across the pathway from the tigers and the lions.
It's one of the few exhibits in your photos I have no recollection of at all - I can't swear to it but I think these are new. The only place I remember seeing leopards was in the Mammal Kingdom/'Jurassic Park' (in my mind!) exhibits.
Hmm... I remember the leopard being formerly housed in an open enclosure ("Jurassic Park" area as Maguari calls them), or have i confused them with another Malaysian zoo?
"Interesting" choice of fencing. IIRC there was some debate in Malaysia over the safety of this enclosure, not so much about the type of fencing (which i think is a more glaring issue) but rather the lack of a safety barrier between the mesh and visitor path.
