When I try to grep CPython with `__super__` I get 0 results:
```
(.venv) ~/Desktop/cpython main ✔
» ag __super__ .
```
That's how we can understand that the naming is not the best.
Summary
--
During the release today, I noticed that the changelog is finally too
long to
render at all on GitHub. This PR follows the same splitting procedure as
in
uv (astral-sh/uv#11510, astral-sh/uv#12099): first splitting the file
into one
per minor version, and then reversing the contents of each file to start
with
the breaking release (`changelogs/0.11.x.md` starts with 0.11.0 instead
of
0.11.13 as in the old changelog).
For the second part, I used
[`reverse-changelog.py`](https://github.com/astral-sh/uv/blob/main/scripts/reverse-changelog.py)
from the uv repo, so hopefully everything is correct. I spot-checked
0.7.0 at least.
This involved slightly more code changes than usual for a stabilization
- so maybe worth double-checking the logic!
I did verify by hand that the new stable behavior on the test fixture
matches the old preview behavior, even after the internal refactor.

Deprecates PD901 as part of #7710. I don't feel particularly strongly
about this one, though I have certainly used `df` as a dataframe name in
the past, just going through the open issues in the 0.12 milestone.

## Summary
- Stabilizes RUF058 (starmap-zip) rule by changing it from Preview to
Stable
- Migrates test cases from preview_rules to main rules function
- Updates snapshots accordingly and removes old preview snapshots
## Test plan
- ✅ Migrated tests from preview to main test function
- ✅ `make check` passes
- ✅ `make test` passes
- ✅ `make citest` passes (no leftover snapshots)
## Rule Documentation
- [Test
file](https://github.com/astral-sh/ruff/blob/main/crates/ruff_linter/src/rules/ruff/mod.rs#L103-L104)
- [Rule documentation](https://docs.astral.sh/ruff/rules/starmap-zip/)
## Summary
Stabilizes the UP049 rule (private-type-parameter) by moving it from
Preview to Stable.
UP049 detects and fixes the use of private type parameters (those with
leading underscores) in PEP 695 generic classes and functions.
## Test plan
- Verified that UP049 tests pass:
`crates/ruff_linter/src/rules/pyupgrade/mod.rs`
- Ran full test suite with `make test`
- Confirmed that no test migration was needed as UP049 was already in
the main `rules` test function
## Rule documentation
https://docs.astral.sh/ruff/rules/private-type-parameter/
Note that the preview behavior was not documented (shame on us!) so the
documentation was not modified.

This PR stabilizes the FURB162 rule by moving it from preview to stable
status for the 0.12.0 release.
## Summary
- **Rule**: FURB162 (`fromisoformat-replace-z`)
- **Purpose**: Detects unnecessary timezone replacement operations when
calling `datetime.fromisoformat()`
- **Change**: Move from `RuleGroup::Preview` to `RuleGroup::Stable` in
`codes.rs`
## Verification Links
- **Tests**:
[refurb/mod.rs](https://github.com/astral-sh/ruff/blob/main/crates/ruff_linter/src/rules/refurb/mod.rs#L54)
- Confirms FURB162 has only standard tests, no preview-specific test
cases
- **Documentation**:
https://docs.astral.sh/ruff/rules/fromisoformat-replace-z/ - Current
documentation shows preview status that will be automatically updated
This PR stabilizes the RUF053 rule by moving it from preview to stable
status for the 0.12.0 release.
## Summary
- **Rule**: RUF053 (`class-with-mixed-type-vars`)
- **Purpose**: Detects classes that have both PEP 695 type parameter
lists while also inheriting from `typing.Generic`
- **Change**: Move from `RuleGroup::Preview` to `RuleGroup::Stable` in
`codes.rs` and migrate preview tests to stable tests
## Verification Links
- **Tests**:
[ruff/mod.rs](https://github.com/astral-sh/ruff/blob/main/crates/ruff_linter/src/rules/ruff/mod.rs#L98)
- Shows RUF053 moved from preview_rules to main rules test function
- **Documentation**:
https://docs.astral.sh/ruff/rules/class-with-mixed-type-vars/ - Current
documentation shows preview status that will be automatically updated
Note that the preview behavior was not documented (shame on us!) so the
documentation was not modified.

## Summary
Closes: astral-sh/ty#552
This PR adds support for step 5 of the overload call evaluation
algorithm which specifies:
> For all arguments, determine whether all possible materializations of
the argument’s type are
> assignable to the corresponding parameter type for each of the
remaining overloads. If so,
> eliminate all of the subsequent remaining overloads.
The algorithm works in two parts:
1. Find out the participating parameter indexes. These are the
parameters that aren't gradual equivalent to one or more parameter types
at the same index in other overloads.
2. Loop over each overload and check whether that would be the _final_
overload for the argument types i.e., the remaining overloads will never
be matched against these argument types
For step 1, the participating parameter indexes are computed by just
comparing whether all the parameter types at the corresponding index for
all the overloads are **gradual equivalent**.
The step 2 of the algorithm used is described in [this
comment](https://github.com/astral-sh/ty/issues/552#issuecomment-2969165421).
## Test Plan
Update the overload call tests.
