 * Run the unit tests (Twisted/trial and asyncio/pytest) in CI on every supported Python: CPython 3.11–3.14 and PyPy 3.11, instead of on CPython 3.14 only, and with all four compression extensions installed (``python-snappy`` is added to the ``dev`` extra; ``just check-compressors`` verifies all four are available) (#1986)
 * Adopt the contribution workflow shared by all WAMP projects: ``CONTRIBUTING.md``, the pull request template and ``.audit/README.md`` are now deployed byte-identically from wamp-cicd (GitHub issue first, red → green tests, AI-assistance disclosure) and kept in sync by a CI drift check; everything specific to Autobahn|Python moved to a new ``DEVELOPMENT.md`` (also included in the docs). ``.cicd`` is pinned to wamp-cicd ``38ded6a``, the same commit across the WAMP fleet (#1956)
+* Remove the opt-in entropy depletion tests (``autobahn/test/test_rng.py``, enabled by ``AUTOBAHN_CI_ENABLE_RNG_DEPLETION_TESTS``, never run in CI): they read ``/proc/sys/kernel/random/entropy_avail``, which has been a constant 256 since Linux 5.18, and ``/dev/random`` no longer blocks since Linux 5.6, so one test passed whatever happened and the other always failed (#1278)
 * Add an ``import-smoke-lowest`` CI job (``just test-imports-lowest``) that runs the import smoke test on CPython 3.11 with every direct dependency resolved to the lowest version ``pyproject.toml`` allows (``uv --resolution lowest-direct``), so stale version floors are caught. The import smoke test now also covers the Twisted and asyncio bindings, each module imported in a fresh interpreter (#1955)
