### Rationale for this change
Add [Python 3.15](https://docs.python.org/3.15/whatsnew/3.15.html) to the pyarrow nightly builds, so that issues can be detected early in the development cycles of both cpython & pyarrow.
Note:
- ~~CFFI and~~ Pandas doesn't have nightly 3.15 wheels, and are accordingly excluded.
- Numpy shipped 3.15rc1 in 2.5.2 ~~doesn't ship a 3.15 wheel, but is needed to build. It is building from source.~~
- [3.15 Schedule](https://peps.python.org/pep-0790/) This PR targets 3.15.0rc1. rc2 is expected 2026-09-01 and final 2026-10-01.
### What changes are included in this PR?
- Adding cp315/cp315t to the build matrix
- Excluding ~~cffi/~~ pandas for 3.15, as the wheels aren't yet available.
### 2026-08-13 edit
- Bump libcst to 1.9.0
- Update manylinux image to 2026.08.08-1 (for 3.15rc1)
- Add -rc to PYTHON_IMAGE_TAG
- Disable pandas tests if Pandas isn't installed:
### Are these changes tested?
- Yes, tested on a local Linux build using the `ninja-release-python` preset (not maximal)
### Are there any user-facing changes?
No functional changes, other than allowing the user to use Python 3.15.
* GitHub Issue: #48172
### Progress Notes (2026-08-15)
Each platform uses different sources for Python builds, each with different release schedules and paths:
- [manylinux](https://github.com/pypa/manylinux) is prebuilt with latest Python builds in `/opt/python`, so using the latest manylinux build is sufficient. 3.15 wasn't available until beta 1.
- musllinux: Uses Alpine system python built from https://github.com/docker-library/python/pull/1123. Might need to bump ALPINE_LINUX version in [arrow/dev/tasks/python-wheels/github.linux.yml](https://github.com/apache/arrow/blob/e611f48081ec927e18e5bcb72fbd071c15c76b08/dev/tasks/python-wheels/github.linux.yml#L35).
- musllinux free-threaded: uses [astral's builds](https://github.com/astral-sh/python-build-standalone). Edit `python-free-threaded-wheel-musllinux-test-imports.dockerfile` + `-test-unittests.dockerfile`: set the python_patch_version, and set build_date in `compose.yaml`.
- macos: Downloads official build from python.org, see `ci/scripts/install_python.sh`. For early builds, needed to disable `--only-binary` since at least one dependency needed to be built (no 3.15 wheels available yet)... only macos uses --only-binary
- Windows: installs builds using `choco`, see `python-wheel-windows-test-vs2022.dockerfile` and `python-free-threaded-wheel-windows-test-vs2022.dockerfile`
For 3.15.0rc1 builds, some care was needed because certain paths needed 3.15.0 and others needed the full 3.15.0rc1.

### Rationale for this change
Python 3.10 is End of Support on October 2026. We can drop support on PyArrow 26.0.0.
See: https://endoflife.date/python
### What changes are included in this PR?
Remove support for 3.10. Update minimum required Python version and update some CI jobs to use the minimum Python supported version.
Some CI jobs using default Python 3.10 (Ubuntu 20.04) have been bumped.
### Are these changes tested?
They will be tested via CI and Archery
### Are there any user-facing changes?
Yes in terms of not supporting older versions of Python. This will be a breaking change for some users but not for the API itself

### Rationale for this change
When adding support to Python 3.14 the musllinux wheels failed with newer versions of the musllinux quay.io image. In order to prepare for the next Python 3.15 release we will require newer base images and we should fix the issues we originally found.
### What changes are included in this PR?
- Update Manylinux and Musllinux quay.io images to `2026.05.31-3`
- Use mold linker instead of ld on alpine in order to solve import segfault on pyarrow musllinux amd64
- Remove Python 3.13 free-threaded wheels as Python 3.13t is not available anymore on the underlying manylinux image, see:
- https://github.com/apache/arrow/issues/50086
### Are these changes tested?
Yes via archery
### Are there any user-facing changes?
Yes, Python 3.13 free threaded was experimental, PyPA removed cp313t from the underlying manylinux docker image. We won't support wheels for 3.13 free-threaded anymore. We will support for 3.14 on-wards.

### Rationale for this change
Warnings in the docker compose step, see https://github.com/ursacomputing/crossbow/actions/runs/19167940422/job/54793047049#step:7:55
### What changes are included in this PR?
Instead of adding `PYTHON_PATCH_VERSION` to `.env` I have moved the use of the patch version to the free-threaded musllinux jobs as `PYTHON_PATCH_VERSION` was only needed there.
I have also updated all Python patch versions from `3.13.7` to `3.13.9`.
### Are these changes tested?
Yes, CI and extended python wheels builds should pass.
### Are there any user-facing changes?
No.

### Rationale for this change
Building free-threaded wheels is necessary to support the free-threaded build. We probably want to upload these wheels as nightlies somewhere as well, so that downstream users can test the free-threading-related changes.
### What changes are included in this PR?
- Add necessary configuration to build 3.13 free-threading wheels on `manylinux`.
- Do necessary changes to build free-threaded wheels on macOS as well.
### Are these changes tested?
I tested the `manylinux` wheel builds. macOS is still untested, since it's not dockerized.
### Are there any user-facing changes?
No.
Related to #43536.

### Rationale for this change
Like #43519 mentionies, now that the first `rc` is out, it's probably time to add CI coverage for Python 3.13 (and also start building wheels).
### What changes are included in this PR?
I'm fairly new to the build/CI processes of the project, but I tried to follow the same template as #37901. I'll follow up afterwards with adding CI coverage for the free-threaded build as well.
