.. towncrier-draft-entries:: Unreleased

.. towncrier release notes start

---

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)

---

• File locks now raise ValueError at construction when mode denies the owner read or write, such as mode=0o444, instead of failing on a later acquire and staying broken until someone deletes the lock file. :pr:760

---

4.0.6 (2026-09-28)

---

• Reject negative blocking timeouts other than -1 before reentrant ReadWriteLock and SoftReadWriteLock acquisition. Preserve unlimited waits and nonblocking acquisition. :pr:756

---

4.0.5 (2026-09-28)

---

• Fix MarkerSoftFileLock acquisition and prevent contenders from evicting live protocol-2 owners after two seconds. Reclaim recognized records after owner death; preserve unknown contracts. :pr:749
• Honor instance timeout and blocking settings in sync and async ReadWriteLock acquisition, including waits between tasks on one instance. Preserve explicit per-call overrides. :pr:750
• Skip access-denial checks when the process can read mode-0o000 files. Keep mode-bit checks enabled for privileged processes on filesystems that support POSIX permissions. :pr:753
• Skip vanished StrictSoftFileLock claims after a read-permission retry expires. Recheck the directory before raising a protocol error so concurrent removal does not turn a stale claim listing into an acquisition failure. :pr:754
