+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+## [Unreleased]
+
+### Added
+
+- New example project based on NREL 5MW land based turbine (`examples/NREL_5MW_Land`)
+- New example project based on NREL 5MW monopile turbine with HydroDyn and SubDyn (`examples/NREL_5MW_Monopile`)
+- Ability to load existing results and Campbell diagram when selecting linearization folder
+- Analysis: Add Copy feature for Analysis cases [#3](https://github.com/deslaughter/acdc-app/issues/3)
+- Results: Add button to visualize all operating points in line
+
+### Changed
+
+- Evaluate: SttsTime sets itself to 6, ignoring user input [#4](https://github.com/deslaughter/acdc-app/issues/4)
+- Evaluate: Output defaults for OpenFAST [#5](https://github.com/deslaughter/acdc-app/issues/5)
+
+### Fixed
+
+- Results: Screen going blank when swapping diagram points
+- Results: Results tab breaking when visualizing last OP [#2](https://github.com/deslaughter/acdc-app/issues/2)
+- Model: "Model" tab doesn't work [#6](https://github.com/deslaughter/acdc-app/issues/6)
+- Model: SubDyn filename in generated .fst-file and name of SubDyn-file in folder not compatible [#7](https://github.com/deslaughter/acdc-app/issues/7)
+
+## v0.2.0-alpha
+
+This release adds many features to ACDC
+
+### Added
+
+- Ability to customize Campbell Diagram
+    - Line labels
+    - Line colors
+    - Swap points between lines
+    - Filter non-structural modes (experimental)
+- Visualize mode shapes for top, front, right-side, and isometric views of turbines
+- Visualize path of nodes in mode shape animation to aid in mode identification
+
+## v0.1.0-alpha
+
+Initial alpha release of ACDC. This version has the following features:
+
+- Create project
+- Import OpenFAST model files
+- Set recommended model defaults for performing linearization
+- Configure analysis cases with wind speed, rotor speed, and blade pitch curve
+- Generate operating points using spline interpolation of condition curve
+- Run simulations and perform linearization at all operating points in parallel
+- Import linearization files and perform multi-blade coordinate transform (MBC)
+- Perform Eigenanalysis of transformed state matrix to get turbine natural frequency and damping
+- Use modal assurance criteria (MAC) to connect modes across operating points
+- Generate Campbell Diagram plot and display it to user
+- Use spectral clustering to correct modes that transform across operating points
