+All notable changes to this project will be documented in this file.
+
+## [6.0.0] 2025-01-28
+
+### Breaking changes
+
+Now, HawkEye uses MiniJinja as the template engine.
+
+All the `properties` configured will be passed to the template engine as the `props` value, and thus:
+
+* Previous `${property}` should be replaced with `{{ props["property"] }}`.
+* Previous built-in variables `hawkeye.core.filename` is now `attrs.filename`.
+* Previous built-in variables `hawkeye.git.fileCreatedYear` is now `attrs.git_file_created_year`.
+* Previous built-in variables `hawkeye.git.fileModifiedYear` is now `attrs.git_file_modified_year`.
+
+New properties:
+
+* `attrs.git_authors` is a collection of authors of the file. You can join them with `, ` to get a string by `{{ attrs.git_authors | join(", ") }}`.
+
+### Notable changes
+
+Now, HawkEye would detect a leading BOM (Byte Order Mark) and remove it if it exists (#166). I tend to treat this as a bug fix, but it may affect the output of the header.
