 ### Breaking changes
 
 - **Python 3.14 is now the default stable version**
-
+  
   The default Python version has changed from 3.13 to 3.14. This applies to Python version installation when no Python version is requested, e.g., `uv python install`. By default, uv will use the system Python version if present, so this may not cause changes to general use of uv. For example, if Python 3.13 is installed already, then `uv venv` will use that version. If no Python versions are installed on a machine and automatic downloads are enabled, uv will now use 3.14 instead of 3.13, e.g., for `uv venv` or `uvx python`. This change will not affect users who are using a `.python-version` file to pin to a specific Python version.
 - **Allow use of free-threaded variants in Python 3.14+ without explicit opt-in** ([#16142](https://github.com/astral-sh/uv/pull/16142))
-
+  
   Previously, free-threaded variants of Python were considered experimental and required explicit opt-in (i.e., with `3.14t`) for usage. Now uv will allow use of free-threaded Python 3.14+ interpreters without explicit selection. The GIL-enabled build of Python will still be preferred, e.g., when performing an installation with `uv python install 3.14`. However, e.g., if a free-threaded interpreter comes before a GIL-enabled build on the `PATH`, it will be used. This change does not apply to free-threaded Python 3.13 interpreters, which will continue to require opt-in.
 - **Use Python 3.14 stable Docker images** ([#16150](https://github.com/astral-sh/uv/pull/16150))
-
+  
   Previously, the Python 3.14 images had an `-rc` suffix, e.g., `python:3.14-rc-alpine` or
 `python:3.14-rc-trixie`. Now, the `-rc` suffix has been removed to match the stable
 [upstream images](https://hub.docker.com/_/python). The `-rc` images tags will no longer be
 updated. This change should not break existing workflows.
 - **Upgrade Alpine Docker image to Alpine 3.22**
-
+  
   Previously, the `uv:alpine` Docker image was based on Alpine 3.21. Now, this image is based on Alpine 3.22. The previous image can be recovered with `uv:alpine3.21` and will continue to be updated until a future release.
 - **Upgrade Debian Docker images to Debian 13 "Trixie"**
-
+  
   Previously, the `uv:debian` and `uv:debian-slim` Docker images were based on Debian 12 "Bookworm". Now, these images are based on Debian 13 "Trixie". The previous images can be recovered with `uv:bookworm` and `uv:bookworm-slim` and will continue to be updated until a future release.
 - **Fix incorrect output path when a trailing `/` is used in `uv build`** ([#15133](https://github.com/astral-sh/uv/pull/15133))
-
+  
   When using `uv build` in a workspace, the artifacts are intended to be written to a `dist` directory in the workspace root. A bug caused workspace root determination to fail when the input path included a trailing `/` causing the `dist` directory to be placed in the child directory. This bug has been fixed in this release. For example, `uv build child/` is used, the output path will now be in `<workspace root>/dist/` rather than `<workspace root>/child/dist/`.
