+- New maintainership of code with modular FPGA/GPU focus, under BFGMiner name
+- Complete working support for cross-compiling Windows builds on Linux.
+- Fix usage of low --scan-time settings so it doesn't busy-loop
+- JSON API: Add new 'devdetail' command to get fixed device information
+- JSON API: Implement driver abstraction for extra device status
+- Icarus: Use epoll to wait for serial port input properly, when available
+- Icarus: Workaround buggy USB-UART that causes Icarus to stop mining rarely
+- Icarus: Estimate mining hashrate correctly, calibrated from real-world data
+- Icarus: Parallelize work setup with Icarus hash search improving performance
+- Icarus: More reliable detection and runtime
+- OpenCL: Move GPU-specific data fetching from JSON API to OpenCL driver
+- OpenCL: Dynamically load OpenCL library, to be more vendor-independent and
+allow use without actually having OpenCL (i.e. FPGA-only rigs).
