All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Firmware build pipeline: End-to-end firmware assembly from source to deployable image
Build scheduler: Parallel build orchestration with dependency-aware caching
backend.h: Unified platform backend abstraction header for Linux and RTOS targets
package.h: Package metadata and dependency declaration header for modular builds
UI module: Optional LVGL-based UI service for display-equipped products (EOS_ENABLE_UI)
CI tests enabled: Unit test suites now run automatically in CI across all 3 platforms
Multicore SMP/AMP: Enhanced multicore scheduling with per-core load balancing
41 product profiles: Full coverage across automotive, medical, aerospace, consumer, industrial, networking, financial, server, and HMI
33 HAL peripherals: Complete hardware abstraction layer with conditional compilation
Cross-compilation toolchains: CMake toolchain files for AArch64 Linux (aarch64-linux-gnu), ARM hard-float (arm-linux-gnueabihf), and RISC-V 64 (riscv64-linux-gnu)
Multi-arch release workflow: Automated cross-compiled binary releases for 4 architectures (x86_64, AArch64, ARM hard-float, RISC-V)
CI/CD pipeline: GitHub Actions workflows for CI (ubuntu, windows, macos + 6 product builds) and release automation

datacenter.h/c: Replaced GCC-only __builtin_popcount() with portable eos_popcount32() — was breaking all MSVC/Windows builds
os_services.c: Fixed hardcoded /tmp/ path with _WIN32 guard using %TEMP% — OTA downloads were failing on Windows
hal_extended.h: Fixed wrong type eos_imu_data_t → eos_imu_vec3_t in eos_hal_ext_backend_t — was breaking all product builds
motor_ctrl.h: Added missing #include <stddef.h> for size_t — was failing on ubuntu, macos, and product builds (robot, automotive)

HAL: 33 peripheral interfaces (GPIO, UART, SPI, I2C, Timer, ADC, DAC, PWM, CAN, USB, Ethernet, WiFi, BLE, Cellular, NFC, IR, Camera, Audio, Display, HDMI, GPU, GNSS, IMU, Radar, Motor, Haptics, Flash, SDIO, RTC, DMA, Watchdog, Touch, PCIe)
Kernel: Task management, mutex, semaphore, message queue, software timers, multicore SMP/AMP
Driver framework: Probe/remove lifecycle, power management hooks
Services: Crypto (SHA-256/512, AES, RSA, ECC, CRC), security (keystore, ACL, secure boot), OS services (watchdog, audit, secure storage, integrity), OTA updates, filesystem, sensor framework, motor control with PID, datacenter (virtualization, BMC/IPMI, RAID, thermal, load balancer, routing, QoS, failover)
Compatibility layers: POSIX threads/sync/signals/IO, VxWorks tasks/semaphores/watchdog/message queues, Linux IPC (SysV shared memory, semaphores, message queues)
41 product profiles covering automotive, medical, aerospace, consumer, industrial, networking, financial, server, and HMI categories
Platform backends: Linux (sysfs/ioctl) and RTOS (register-level)
Power management: Sleep/deep-sleep/standby state machine
Networking: Socket abstraction layer
Systems: Firmware assembly, rootfs generation, system image builder
Toolchain management: YAML-based toolchain definitions with runtime parser
