+# Changelog
+## 0.5.0
+
+### Introduction
+Support for Environmental Data Retrieval (EDR) was added in this version to extend OGC capabilities.
+EDR is optional and can be enabled via the OGC_SUPPORTED_FORMATS environmental variable.
+The currently supported version of EDR is v1.1.0. Additionally, the repository was modernized by
+adding a development container, pyproject.toml, and Github Actions for linting, formatting, 
+unit testing and scanning.
+
+### Features
+* Added support for EDR v1.1.0.
+
+### Maintenance
+* Added unit testing for code coverage requirements.
+* Added development container and pyproject.toml file.
+* Added Github Actions for linting, formatting, unit testing, and scanning.
+
+### Bugfixes
+* Fixed formatting, linting, and SonarQube errors to pass CI/CD scans.
