---

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
• Reject negative timeouts other than -1 in blocking AsyncReadWriteLock and AsyncSoftReadWriteLock acquisitions. Keep -1 as an unlimited wait and ignore timeouts when blocking=False. :pr:755

---

4.0.4 (2026-09-26)

---

• Hostnames that still differ after their first 253 escaped characters now publish distinct owners, so a soft lock no longer takes another such host's live holder for its own and reclaims its marker. :pr:748

---

4.0.3 (2026-09-23)

---

• Importing filelock on CPython 3.10 or 3.11 no longer makes new threads fail with RuntimeError: Cannot install a trace function while another trace function is being installed under coverage or a debugger. filelock skips its fork-safety audit hook there, so forking from inside a thread's own lock-state transition no longer raises immediately on those versions. :pr:747

---

4.0.2 (2026-09-23)

---
