SmartHeap is a dll library that been present previously. It optional. It just updated (but not needed) Shw32.dll.
Timer Mode is optional too. Current versions have support for some side-loaded mods. Showing times is example - it loaded from separate file. Like clouds Wrapper.ff, but clouds is just checkbox in settings while timers is in differ menu.
Timer mod can be useful. Count turn time in multiplayer.
I guess there is somewhere zip variant. On official blog, russian official thread or on russian community on VK(facebook-like) site.
