• Support for LinuxMint (@h4tr3d)

Examples

• 256-color mode VGA (@lefticus)
• Snake rewrite (@Voultapher)

• Stack switching utility (context). Create and use custom area in memory as
  stack for a provided delegate.
• CPUID (@gurka). Includes KVM feature support

Misc

• Minor fixes and refactoring (@RicoAntonioFelix)
• Move ELF symbols (yet again) into its own section, but pre-pruned
• Further reductions in binary sizes
• Move stack to the old 640k conventional memory hole, reducing memory usage
• Updated logotype and READMEs

Heap debugging

• Validate new and frees
• Buffer overflow checks (@gurka)
• Verbose mode for tracking allocations

Utility

• Added Logger - ring buffer log utility
• Added Timer - makes it easier to start, stop and restart a task

Profiling

• Add mode toggle for stack sampler allowing Switch between caller mode
  (show who calls function) and current mode (show current function).

Networking

• Packet now travels through the network stack as a unique_ptr instead of
  shared_ptr (avoiding control block allocation)
• Isolated network layering a bit by moving ethernet address to hw::MAC_addr
• TCP optimizations
  • Fixed bug where read would result in double free
  • No longer sets up default callbacks, saving allocations
  • Minor reduction in size

Testing

• Improvements to test automation
