 - Migrated packaging from `setup.py` to `pyproject.toml` (PEP 621) with a PEP 639 SPDX license expression (`LGPL-3.0-or-later`). Moved the ruff config into `[tool.ruff]`, and removed `setup.py`, `build-release.py`, and `ruff.toml`. Build with `python -m build`; the version is read dynamically from `pystrix.VERSION`.
 
 ### Removed
-- The Python 2 compatibility shims: the `queue` and `socketserver` import fallbacks, the `basestring` branch in `generic_transforms`, and the explicit `(object)` base classes. The codebase is now Python 3 only.
+- The Python 2 compatibility shims: the `queue` and `socketserver` import fallbacks, the `basestring` branch in `generic_transforms`, and the explicit `(object)` base classes. The codebase is now Python 3 only. Dropping Python 2 is released as a pragmatic minor bump rather than a major one, since Python 2 support was already nominal and end-of-life.
 
 ### Fixed
 - Narrowed the bare `except` around `line.decode()` in `_AGI._read_line` to an `isinstance(line, bytes)` check. A real `UnicodeDecodeError` on malformed socket bytes now surfaces instead of being swallowed and leaving raw bytes in the line (#50).

+| pystrix | Python |
+| --- | --- |
+| 1.3.x | 3.9 – 3.13 |
+| 1.2.0 and earlier | 2.7, 3.4+ (legacy, unmaintained) |

+From 1.3.0 on, the `requires-python` metadata makes pip resolve automatically: a project on an older Python receives 1.2.x. All versions target Asterisk 1.10+.
