- callbacks now have a uintptr_t "cbData" parameter (instead of haphazard void*/uintptr_t, cb/ctx/data) - resource loading code now more uniformly deals with u8* pointers instead of void* allocators: add support for page_aligned_alloc via boost::shared_ptr. add evil hack to avoid the need for default ctor and ensure alignment in SingleAllocator archive: improve Decompressor compression: . near complete rewrite (previous code was a poorly factored mess) . fix bug related to buffer allocation . no longer provide get_output API (prone to abuse) . add call to get max. size of output buffer (for preallocation) This was SVN commit r5370.
