+All notable changes to this project will be documented in this file.
+
+
+## [Unreleased]
+
+## [1.0.1b] - 2025-08-15
+
+### Added
+
+#### Instrument Support
+- Support for GOES-ABI instrument alongside MSG-SEVIRI
+- New `load_goes_abi()` method for GOES-ABI configuration with 16 spectral channels
+- Generic `load_instrument()` method for instrument-agnostic loading
+
+#### Code Structure and Organization
+- Parametrized tests for both SEVIRI and ABI instruments using pytest
+- Test utilities for loading predefined atmospheric profiles
+- Comprehensive test coverage for different channel configurations
+- Bash script for running both unit tests and Jupyter notebook execution
+
+#### Data Handling
+- Enhanced error handling with specific exception types (e.g., `KeyError`, `FileNotFoundError`)
+- Improved filename pattern matching and sorting for data processing
+- Support for symbolic link creation for data management
+
+#### Documentation
+- NumPy-style docstrings throughout the codebase
+- Enhanced API documentation structure
+- Improved function parameter documentation
+
+### Changed
+
+#### Instrument Configuration
+- Refactored instrument loading with case-insensitive instrument selection
+- Renamed variables from `chan_list_seviri`/`nchan_seviri` to generic `chan_list_instrument`/`nchan_instrument`
+- Renamed `load_seviri()` to `load_msg_seviri()` for consistency
+- Updated instrument attribute naming for better clarity
+
+#### Code Quality
+- Replaced bare `except` clauses with specific exception handling
+- Improved code modularity and separation of concerns
+- Enhanced variable naming conventions for better readability
+
+#### Testing Infrastructure
+- Improved test script with sorted output and hidden path exclusion
+- Enhanced workflow testing for multiple instruments
+- Better test organization and parameterization
+
+### Fixed
+
+#### File Processing
+- File path handling in test scripts and data processing
+- Channel list sorting in workflow execution
+- Hidden file/directory exclusion in file search operations
+
+#### Data Processing
+- Pressure calculation and coordinate handling in ERA data processing
+- Specific humidity clipping with configurable minimum values
+- Time coordinate selection and merging in multi-dimensional datasets
+
+### Technical Details
+
+#### Dependencies
+- Maintains compatibility with existing pyrttov, xarray, and numpy dependencies
+- Added support for pytest parameterization features
+- Enhanced Jupyter notebook execution capabilities
+
+#### Performance
+- Optimized file searching with improved find commands
+- Better memory management in chunked data processing
+- Streamlined instrument loading procedures
+
+## [1.0.0] - 2024-04-16
+
+### Added
+- Initial release of SynSatiPy
+- MSG-SEVIRI instrument support for satellite radiance simulation
+- ERA5 and ICON model data input support
+- RTTOV integration for radiative transfer calculations
+- Basic test framework and example notebooks
+- Documentation structure and API reference
+
+### Dependencies
