 ## [Unreleased]
 
+## [0.1.0-beta.1] - 2025-12-02
+
+### Added
+- Hardware Abstraction Layer (HAL) with instrument interface protocols
+  - IThermalChamber protocol with temperature control methods
+  - IPowerSupply protocol with voltage/current control and measurement
+  - IMultimeter protocol with DC voltage, current, and resistance measurement
+- Instrument drivers implementing HAL interfaces
+  - ThermalChamberDriver implements IThermalChamber
+  - PowerSupplyDriver implements IPowerSupply
+  - MultimeterDriver implements IMultimeter
+- Instrument factory pattern for backend abstraction
+  - InstrumentSet dataclass containing chamber, PSU, and DMM
+  - InstrumentConfig for specifying backend (simulator/pyvisa) and connection details
+  - InstrumentFactory.create() for creating instrument sets from configuration
+- Transport layer abstraction
+  - Transport ABC defining connect/disconnect/read/write/query interface
+  - TCPTransport implementation for TCP/IP connections
+- Comprehensive test suite for HAL (16 tests)
+  - Interface implementation verification
+  - Factory pattern testing with mocked backends
+  - Configuration validation
+
+### Changed
+- Drivers now explicitly inherit from interface ABCs for maximum type safety
+- Moved InstrumentServer to instruments/transport for better architecture
+
+### Technical
+- ABC-based interfaces ensure compile-time interface compliance
+- Factory pattern enables seamless switching between simulated and real hardware
+- All HAL components fully type-checked with mypy strict mode
