+# Changelog
+
+All notable changes to Velxio will be documented in this file.
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
+
+## [2.0.1] - 2026-04-22
+
+### Added
+- Enhanced electrical simulation with ngspice-WASM engine for accurate analog circuit analysis
+- Expanded component catalog with 44 SPICE-compatible parts including logic gates, transistors, op-amps, regulators, and electromechanical components
+- Added 40 new circuit examples demonstrating analog, digital, and electromechanical concepts
+- Introduced custom web components for electronic elements (relays, resistors, capacitors, inductors, transistors)
+- Implemented ESP32 ADC waveform simulation with periodic 12-bit waveform look-up tables and interpolation
+- Added voltmeter and ammeter instrument components for real-time circuit measurements
+- Created comprehensive end-to-end tests for electrical simulation including capacitor charging, rectifier behavior, and waveform analysis
+- Added GitHub Actions workflow for circuit simulation testing on every push and PR
+
+### Changed
+- Renamed all components to use 'velxio-' prefix for consistency
+- Enabled electrical simulation by default (always-on SPICE mode) instead of requiring manual activation
+- Enhanced LED brightness simulation to reflect actual current flow from SPICE calculations
+- Updated backend to handle unhandled asyncio exceptions and prevent process crashes
+- Improved component metadata generation to prevent CI drift and enforce up-to-date metadata
+- Refactored property synchronization in simulation parts to use event-based system
+- Expanded ADC pin mapping to support all 18 board types for full microcontroller integration
+
+### Fixed
+- Fixed sitemap generation to include all circuit examples for better SEO visibility
+- Resolved floating input node issues in RC low-pass filter circuits that caused SPICE singular matrix errors
+- Updated proxy configuration to use 127.0.0.1 for improved compatibility
+- Fixed metadata regeneration to properly include custom components in the component picker
+- Improved backend entrypoint script to ensure clean container restarts when processes die
+
+## [2.0.1] - 2026-04-17
+
+### Added
+- Added ATtiny85 support with examples and simulation tests
+- Added BMP280 sensor component with circuit preview and SVG representation
+- Added example detail pages with improved SEO and sitemap generation
+- Added MicroPython support for RP2040 (Pico), ESP32, ESP32-S3, and ESP32-C3 boards
+- Added ability to upload precompiled firmware files (.hex, .bin, .elf) directly into the emulator
+- Added ability to remove boards from workspace with confirmation dialog
+- Added I2C sensor support with slave emulation for MPU6050, BMP280, DS1307, and DS3231 sensors
+- Added ESP32 WiFi/BLE emulation with ESP-IDF compilation pipeline
+- Added VS Code extension skeleton for local simulation
+- Added comprehensive documentation for ESP32 GPIO sensor simulation, Docker infrastructure, and MicroPython implementation
+- Added auto-compile feature that triggers compilation when pressing Play if code changed or no firmware loaded
+- Added share functionality for projects and examples with visibility toggle
+- Added component metadata overrides and enhanced property controls
+- Added new CI/CD workflows for backend unit tests, end-to-end tests, and automated Discord release notifications
+- Added Docker multi-architecture support (amd64 + arm64) and pre-built ESP-IDF toolchain image
+
+### Changed
+- Enhanced auto-compile to use board's file group for WiFi detection instead of legacy global files
+- Updated CircuitPreview component and implemented ShareModal using createPortal
+- Enhanced Arduino pin tracing in DynamicComponent and updated LittleFS WASM initialization
+- Enhanced ESP-IDF compiler library resolution logic and added support for dynamic library detection
+- Enhanced wire connection handling and GND checks for components
+- Enhanced logging for library loading and WiFi progress
+- Updated Docker build processes with optimized build contexts and multi-architecture support
+- Changed WiFi SSID normalization to match QEMU access points for reliable ESP32 WiFi connection
+- Refactored I2C slave tests for ESP32 with improved event handling and ACK/NACK responses
+
+### Fixed
+- Fixed container restart issue by monitoring both backend and nginx processes
+- Fixed project saving to use active board files/kind and improved error messages
+- Fixed ESP32 boot stability with deterministic instruction counting
+- Fixed ESP32 Run button to auto-compile and recover firmware after page refresh
+- Fixed LED ground check to require cathode wired to GND (or LOW GPIO) to light up
+- Fixed MPU6050Slave I2C handling with improved WHO_AM_I read tracking
+- Fixed ESP32 WiFi SSID/channel alignment with QEMU access_points array
+- Fixed RISC-V toolchain paths for ESP32-C3 compilation
+- Fixed ESP-IDF Python requirements installation in Docker
+- Fixed SaveProjectModal to prevent saving to `/api/projects/none` when project ID is invalid
+- Fixed ESP32 compilation by adding missing dependencies (cmake, ninja-build, git, packaging, libusb)
