- Introduce `defmt` which is very commonly used on embedded systems. It is used to print the allocated structures. - New QEMU runner to support defmt. - Introduce new example which uses a global heap initialized on BSS memory. - Switch to more commonly used thumbv7em-none-eabihf target for the QEMU runner. thumbv6m-none-eabi is still supported as well.
- Added `Heap::free` and `Heap::used` for the TLSF heap. - Added example showcasing regular heap exhaustion and example which shows the memory usage API.
