########### Changelog ###########

.. towncrier-draft-entries:: Unreleased

.. towncrier release notes start

---

4.0.12 (2026-10-05)

---

• Fix read-lock acquisition on SQLite versions older than 3.33.0 by using sqlite_master for the schema probe. :pr:769

---

4.0.11 (2026-10-05)

---

• ReadWriteLock and AsyncReadWriteLock use a validated private hard link when /dev/fd has no entry for the database descriptor, supporting NetBSD's static descriptor directory beyond descriptor 63. The temporary location must share a filesystem with the database. The symlink refusal test accepts NetBSD's error wording.

---

4.0.10 (2026-10-03)

---

• Reusing a singleton AsyncFileLock with another loop, executor or run_in_executor, or a singleton SoftFileLease with another lease_duration, heartbeat_interval or on_compromise, now raises ValueError instead of returning the lock with its original options. :pr:765

---

4.0.9 (2026-10-01)

---

• ReadWriteLock and AsyncReadWriteLock close the descriptor that checks the database path once SQLite has connected, so on PyPy a dropped lock leaves no descriptor open until garbage collection runs. :pr:763
• ReadWriteLock and AsyncReadWriteLock refuse a symlink at the database path instead of following it, so a user who can create names in a shared lock directory cannot point the lock at another file (GHSA-j8f7-rjxc-mr56).

---

4.0.8 (2026-10-01)

---

• ReadWriteLock.release() and SoftReadWriteLock.release() from a thread that does not hold the write lock now raise RuntimeError instead of dropping the holder's lock and letting a second writer in. :pr:761

---

4.0.7 (2026-09-29)

---
