+## Features
+
+**Nord Docs Transition** — #76 ⇄ #77 (⊶ 4456d69e)
+↠ Transferred all documentations, assets and from „Nord Emacs“ to [Nord Docs][nord]
+Please see the [corresponding issue in the Nord Docs repository][gh-nord-docs#155] to get an overview of what has changed for Nord Emacs and what has been done to migrate to Nord Docs.

+
+**Uniform Mode Lines Customization** — #32, #47 ⇄ #48 (⊶ 6b801715) requested by [@localredhead][gh-user-localredhead]
+↠ Added the new theme configuration variable `nord-uniform-mode-lines` to use `nord3` as background color highlighting for both active and inactive mode lines.
+By default, only the mode line of the active buffer uses `nord3` as background color while inactive buffers are dimmed using `nord1`.
+
+```lisp
+(setq nord-uniform-mode-lines t)
+```

+
+
+**Custom Region Highlight Styles** — #45, #32 ⇄ #46 (⊶ b43a2491)
+↠ By default, Nord Emacs uses `nord2` as background color for selected text in the editor to provide a sane default style.
+To use a more colorful highlighting for region selections, Nord Emacs now provides the `nord-region-highlight` configuration that can be set to either `snowstorm` or `frost` to use `nord4` or `nord8` colors from Nord's [Frost][nord-docs-colors#frost] and [Snow Storm][nord-docs-colors#snowstorm] palettes.
+
+```lisp
+;; Use `nord8` from Nord's "Frost" palette as background color.
+(setq nord-region-highlight "frost")
+
+;; Use `nord4` from Nord's "Snow Storm" palette as background color.
+(setq nord-region-highlight "snowstorm")
+```

+
+
+**Custom Color Contrast** — #43 ⇄ #44 (⊶ 3e6bfdae)
+↠ Please note that **this configuration has been implemented and deprecated again in this release version** through #73 that increased the default comment color (`nord3`) brightness by 10% from a lightness level of ~35% to ~45%
+Please see #73 and #74 for more details and the migration guide.
+
+## Improvements
+
+**Comment Color Brightness** — #73 ⇄ #74 (⊶ 9ed7b9c2)
+↠ Implemented the increase of the default comment color (`nord3`) brightness by 10% from a lightness level of ~35% to ~45%.
+
+➜ **Please see [arcticicestudio/nord#94][gh-nord#94] for all details about this design change decision**!
+
+⚠ **NOTE**: This change also **deprecates the „Custom Comment Contrast“ configuration** implemented in #44 that will be removed in Nord Emacs version 1.0.0!
+The default comment color has been adjusted so the configuration is not required anymore for users to increase the brightness on their own.
+To notify users about this change a deprecation warning will be shown when the `nord-comment-brightness` configuration variable has been set and initialized through the user's configuration.
+
+#### Before
+
+Before
+
+
+After
+
+
+**License Header Keyword** — #41 ⇄ #42 (⊶ 24deba86)
+↠ Added a license header keyword to help tools to automatically detect the license type as used by GitHub and Emacsmirror ([licensee][gh-licensee/licensee]).
+
+```lisp
+;; License: Apache-2.0
+```
+
+## Bug Fixes
+
+**Non-Prefixed Names Leaked To Global Environment** — #66 ⇄ #67 (⊶ c4e0b554) by [@slippycheeze][gh-user-slippycheeze]
+↠ Prefixed all top level variable definitions, like custom theme configuration variables, to avoid _leaking_ them in a way that could conflict with other code. The convention of `package--` is used to mirror the most current Emacs coding conventions.
+Sadly this is necessary because Emacs Lisp has no namespaces, so every top level definition is visible to the entire universe including variables and functions.
+
+### Documentation
+
+**Documentation Typo In Package Name** — #39 (⊶ eb7929e4) by [@gguimaraesbr][gh-user-gguimaraesbr]
+↠ Fixed a invalid package name in the installation instructions: `nord` ➜ `nord-theme`
+
+## Tasks
+
+### Documentation
+
+**MIT License Migration** — #57 ⇄ #58 (⊶ b5c1dc76)
+↠ Migrated to the MIT license to adapt to the migration of the main [Nord][gh-nord] project. Detailed information can be found in the [main task ticket][gh-nord#55].
+
+**„Nord Terminix“ References** — #49 ⇄ #50 (⊶ be328794)
+↠ Updated all references to the Terminix project that has been renamed to [Tilix][gh-gnunn1/tilix].
