Features Introduced in This Release
General
- New boot infrastructure
- The new boot infrastructure is more unified and offers similar boot behavior on all supported platforms.
- PearPC support discontinued
- PearPC was the original PowerPC simulator used for the development of HelenOS ppc32 port. However, since this simulator is no longer in active development and even severe flaws have not been fixed for more that 4 years (OFW memory management calls, etc.), we have decided to drop support for this simulator completely instead of adding more quirks to our bootloader and kernel code. Qemu/PPC is currently our PowerPC simulator of choice.
- Added support for the Neo FreeRunner smartphone running on the ARMv4 processor.
Kernel
- Observability
- Kernel panics now have a more unified look and print more informative and meaningful messages.
- Experimental support for kernel stack traces on mips32.
