 # Breaking Changes
 
+## 0.15.0
+
+- **2026 formatter style guide**
+
+    Ruff now formats your code according to the 2026 style guide. See the
+    formatter section in the changelog or blog post for a detailed list of
+    changes.
+
+- **Block suppression comments in the linter**
+
+    The linter now supports block suppression comments. For example, to suppress
+    `N803` for all parameters in this function:
+
+    ```python
+    # ruff: disable[N803]
+    def foo(
+        legacyArg1,
+        legacyArg2,
+        legacyArg3,
+        legacyArg4,
+    ): ...
+    # ruff: enable[N803]
+    ```
+
+- **Alpine Docker image**
+
+    The `ruff:alpine` Docker image is now based on Alpine 3.23 (up from 3.21).
+
+- **Debian Docker image**
+
+    The `ruff:debian` and `ruff:debian-slim` Docker images are now based on Debian 13 "Trixie" instead of Debian 12 "Bookworm."
+
+- **`ppc64` binaries**
+
+    Binaries for the `ppc64` (64-bit big-endian PowerPC) architecture are no longer included in our releases. It should still be possible to build Ruff manually for this platform, if needed.
+
+- **Default Python version and `extend`**
+
+    Ruff now resolves all `extend`ed configuration files before falling back on a default Python version.
+
 ## 0.14.0
 
 - **Default to Python 3.10**
