- Refactored entire codebase (excluding the Insight component) to accommodate multiple target architectures (no longer specific to AVR) - Deleted 'generate SVD' GDB monitor command - I will eventually move this functionality to the Bloom website - Added unit size property to address spaces - Many other changes which I couldn't be bothered to describe here
