In v2.0 (Rev. 2) (04/04/2018), there are APIs for both ap_done interrupts and ap_ready interrupts. The API function calls for the interrupt enable and disable have changed. An additional argument is needed to define a mask for which interrupt to enable/disable. The SetCallback function also has an additional argument to specify the interrupt source.

In v2.0 (Rev. 2) (04/04/2018), the AXI MM interface always operates in conservative mode.

The HLS AXI master interface always checks the data buffer on W channel before it issues a write request. Only when the buffer has more than burst length data is AWVALID asserted. This can help solve deadlock in some systems but usually, the write latency will increase.

In v2.0 (Rev. 2) (04/04/2018), pending AXI transactions can be flushed before reset.
