-### The target Python version now defaults to 3.8 instead of 3.10 ([#6397](https://github.com/astral-sh/ruff/pull/6397))
-
-Previously, when a target Python version was not specified, Ruff would use a default of Python 3.10. However, it is safer to default to an _older_ Python version to avoid assuming the availability of new features. We now default to the oldest supported Python version which is currently Python 3.8.
-
-(We still support Python 3.7 but since [it has reached EOL](https://devguide.python.org/versions/#unsupported-versions) we've decided not to make it the default here.)

-### Import Categorization
-
-To understand Ruff's import categorization system, we first need to define two concepts:
-
-- "Project root": The directory containing the `pyproject.toml`, `ruff.toml`, or `.ruff.toml` file,
-    discovered by identifying the "closest" such directory for each Python file. (If you're running
-    via `ruff --config /path/to/pyproject.toml`, then the current working directory is used as the
-    "project root".)
-- "Package root": The top-most directory defining the Python package that includes a given Python
-    file. To find the package root for a given Python file, traverse up its parent directories until
-    you reach a parent directory that doesn't contain an `__init__.py` file (and isn't marked as
-    a [namespace package](https://beta.ruff.rs/docs/settings/#namespace-packages)); take the directory
-    just before that, i.e., the first directory in the package.
-
-For example, given:
-
-```text
-my_project
-├── pyproject.toml
-└── src
-    └── foo
-        ├── __init__.py
-        └── bar
-            ├── __init__.py
-            └── baz.py
-```
-
-Then when analyzing `baz.py`, the project root would be the top-level directory (`./my_project`),
-and the package root would be `./my_project/src/foo`.
-
-#### Project root
-
-The project root does not have a significant impact beyond that all relative paths within the loaded
-configuration file are resolved relative to the project root.
-
-For example, to indicate that `bar` above is a namespace package (it isn't, but let's run with it),
-the `pyproject.toml` would list `namespace-packages = ["./src/bar"]`, which would resolve
-to `my_project/src/bar`.
-
-The same logic applies when providing a configuration file via `--config`. In that case, the
-_current working directory_ is used as the project root, and so all paths in that configuration file
-are resolved relative to the current working directory. (As a general rule, we want to avoid relying
-on the current working directory as much as possible, to ensure that Ruff exhibits the same behavior
-regardless of where and how you invoke it — but that's hard to avoid in this case.)
-
-Additionally, if a `pyproject.toml` file _extends_ another configuration file, Ruff will still use
-the directory containing that `pyproject.toml` file as the project root. For example, if
-`./my_project/pyproject.toml` contains:
-
-```toml
-[tool.ruff]
-extend = "/path/to/pyproject.toml"
-```
-
-Then Ruff will use `./my_project` as the project root, even though the configuration file extends
-`/path/to/pyproject.toml`. As such, if the configuration file at `/path/to/pyproject.toml` contains
-any relative paths, they will be resolved relative to `./my_project`.
-
-If a project uses nested configuration files, then Ruff would detect multiple project roots, one for
-each configuration file.
-
-#### Package root
-
-The package root is used to determine a file's "module path". Consider, again, `baz.py`. In that
-case, `./my_project/src/foo` was identified as the package root, so the module path for `baz.py`
-would resolve to  `foo.bar.baz` — as computed by taking the relative path from the package root
-(inclusive of the root itself). The module path can be thought of as "the path you would use to
-import the module" (e.g., `import foo.bar.baz`).
-
-The package root and module path are used to, e.g., convert relative to absolute imports, and for
-import categorization, as described below.
-
-#### Import categorization
-
-When sorting and formatting import blocks, Ruff categorizes every import into one of five
-categories:
-
-1. **"Future"**: the import is a `__future__` import. That's easy: just look at the name of the
-    imported module!
-1. **"Standard library"**: the import comes from the Python standard library (e.g., `import os`).
-    This is easy too: we include a list of all known standard library modules in Ruff itself, so it's
-    a simple lookup.
-1. **"Local folder"**: the import is a relative import (e.g., `from .foo import bar`). This is easy
-    too: just check if the import includes a `level` (i.e., a dot-prefix).
-1. **"First party"**: the import is part of the current project. (More on this below.)
-1. **"Third party"**: everything else.
-
-The real challenge lies in determining whether an import is first-party — everything else is either
-trivial, or (as in the case of third-party) merely defined as "not first-party".
-
-There are three ways in which an import can be categorized as "first-party":
-
-1. **Explicit settings**: the import is marked as such via the `known-first-party` setting. (This
-    should generally be seen as an escape hatch.)
-1. **Same-package**: the imported module is in the same package as the current file. This gets back
-    to the importance of the "package root" and the file's "module path". Imagine that we're
-    analyzing `baz.py` above. If `baz.py` contains any imports that appear to come from the `foo`
-    package (e.g., `from foo import bar` or `import foo.bar`), they'll be classified as first-party
-    automatically. This check is as simple as comparing the first segment of the current file's
-    module path to the first segment of the import.
-1. **Source roots**: Ruff supports a `[src](https://beta.ruff.rs/docs/settings/#src)` setting, which
-    sets the directories to scan when identifying first-party imports. The algorithm is
-    straightforward: given an import, like `import foo`, iterate over the directories enumerated in
-    the `src` setting and, for each directory, check for the existence of a subdirectory `foo` or a
-    file `foo.py`.
-
-By default, `src` is set to the project root. In the above example, we'd want to set
-`src = ["./src"]` to ensure that we locate `./my_project/src/foo` and thus categorize `import foo`
-as first-party in `baz.py`. In practice, for this limited example, setting `src = ["./src"]` is
-unnecessary, as all imports within `./my_project/src/foo` would be categorized as first-party via
-the same-package heuristic; but your project contains multiple packages, you'll want to set `src`
-explicitly.
