Release version 0.2 New features and major improvements since v0.1: - HAL: introduced architecture-independent platform interfaces for the kernel. - LoongArch64: added and stabilized boot, interrupt, timer, PCI, memory-management, and signal support. - AArch64: added initial ARM64 boot, trap, timer, firmware, and VirtIO platform support. - RISC-V: reorganized architecture code around the new HAL and expanded platform tests. - Userland: adopted sbase as the default Unix utility suite. - Contest environment: added setup and runner infrastructure for basic, BusyBox, musl, and glibc test workloads. - Testing: introduced reusable platform-test and RISC-V kernel test frameworks. Notable fixes and compatibility: - Memory and signals: improved memory management and signal handling across architectures. - Dynamic loading: fixed external-library compilation and dynamic loader behavior. - mmap: corrected mapping behavior needed by dynamically linked programs. - Contest mode: shut down cleanly after panic and made shutdown tests reliable.
