+### [0.55.0] - 2025-09-15
+#### ✨ Highlights
+
+This cycle, the Pixi team focused on squashing bugs.
+We especially focused on problems that were annoying and open for some time,
+but never quite important to fix *right now*.
+
+#### ⚠️ Breaking Change
+
+The environment variable overwriting logic is changed.
+If you think you haven't read this for the first time, then you are right!
+We already attempted to fix the order and other weird aspects of our environment variable handling in the past,
+but had to revert it, since it broke too many things.
+This time we touched significantly less logic so we hope that the impact will be minimal.
+
+Previously, the variables in your own environment would overwrite the variables set in the Pixi manifest.
+This is now reversed, meaning that the variables set in the Pixi manifest will overwrite the variables in your own environment.
+Also task environment variables will now be considered even if that environment variable was already defined outside of Pixi.
+More info can be found in the [documentation](https://pixi.sh/v0.55.0/reference/environment_variables/).
