+# Bumping the Python version support
+
+This page documents the process for changing the supported Python version
+range and explains the policy behind it.
+
+## Version policy
+
+- **Drop** Python versions that have reached [end-of-life](https://devguide.python.org/versions/).
+- **Add** the most recent minor release that is not the very latest (e.g. add
+  3.12 when 3.13 is already out).  This keeps us current without chasing
+  bleeding-edge releases.
+
+
+## Files to update
+
+| File | What to change |
+|------|----------------|
+| `.github/workflows/ci.yml` | `python-version` matrix; runner OS; action versions; conditions using a specific version (e.g. `== '3.11'`) |
+| `setup.py` | `python_requires`; `Programming Language :: Python :: X.Y` classifiers |
+| `test_requirements.txt` | Add or update compatibility shims (e.g. `packaging` to replace `distutils`) |
+| `README.md` | Prerequisites section Python version line and history note |
+
+## CI action versions
+
+When bumping the runner OS (e.g. `ubuntu-22.04` → `ubuntu-24.04`) also audit
+the pinned action versions for OS compatibility:
+
+- `actions/checkout` — bump to latest v4+
+- `actions/setup-python` — bump to latest v5+
+- `actions/cache` — bump to latest v4+
+- `hidakatsuya/action-setup-diff-pdf` — check release notes; v1.4.0 added
+  Ubuntu 24.04 support
+
+## Python 3.12 compatibility audit
+
+Before opening the bump PR, audit the codebase and notebooks for known Python
+3.12 breaking changes:
+
+**`distutils` removed**
+
+```bash
+grep -r "import distutils" .
+```
+
+Replace with `packaging` (add to `test_requirements.txt` if not present).
+
+**Unrecognized escape sequences become `SyntaxWarning`**
+
+In Python 3.12, `'\mathbf'`, `'\grad'`, etc. are `SyntaxWarning` (previously
+`DeprecationWarning`).  nbval catches the stderr output and fails the cell.
+
+```bash
+python -W error::SyntaxWarning -c "import ast; ast.parse(open('file.py').read())"
+```
+
+For notebooks, search for unquoted backslash sequences in code cells and add
+the `r` prefix: `'\mathbf{e}'` → `r'\mathbf{e}'`.
+
+## Testing locally
+
+```bash
+uv venv --python 3.12 .venv312
+uv pip install -r test_requirements.txt -e .
+flake8 -v
+pytest \
+    -vv --durations=50 \
+    --cov=galgebra \
+    --nbval examples/ipython/ \
+    --nbval examples/primer/ \
+    test \
+    --nbval-current-env \
+    --nbval-sanitize-with test/.nbval_sanitize.cfg \
+    -n 2 --dist loadscope
+```
+
+## Tracking issue pattern
+
+Python bumps often uncover several independent blocking issues (compat
+failures, notebook output changes).  Use the **tracking issue** pattern to
+keep each PR small and reviewable:
+
+1. Open a *tracker* issue describing the overall goal (e.g. "Bump Python to
+   3.10–3.12").  Keep it focused on the goal — do not list specific errors.
+2. For each blocking problem found during testing, open a *sub-issue*
+   describing only that problem.
+3. Add a comment to the tracker referencing all sub-issues.
+4. Open a PR for each sub-issue independently.
+5. Once all sub-PRs are merged, open the final bump PR and close the tracker.
