.. towncrier release notes start

---

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)

---

• Concurrent acquire() and release() on a thread_local=False lock no longer leak the OS lock, close a descriptor twice, drop a lease token, or leave a false deadlock after a cross-thread release (:issue:744). :pr:745
• :class:~filelock.AsyncReadWriteLock and :class:~filelock.AsyncSoftReadWriteLock now give each asyncio task its own hold, so tasks sharing one instance no longer enter the write lock together. :pr:746
• Correct the async cache example to create its data directory and clarify automatic creation of lock-file parent directories. :pr:740
• Exclude sphinx-llm 1.1.0 from documentation dependencies because its Markdown builder emits unknown-node warnings. :pr:742

---

4.0.1 (2026-09-19)

---

• poll_interval is now validated at construction, on the setter, and on acquire(): a negative, non-finite, or non-numeric value raises :class:ValueError/:class:TypeError immediately instead of failing inside time.sleep. :pr:739

---

4.0.0 (2026-09-17)

---

• The :class:~filelock.SoftReadWriteLock on-disk protocol is a generation log under <path>.rw, and a process running an earlier release does not see it: an old and a new participant on one lock path do not exclude each other. Stop every participant, upgrade them all, then restart them; the new code ignores leftover .state, .write and .readers/ files, and you can delete them. The filesystem must provide no-replace hard links, as it must for :class:~filelock.StrictSoftFileLock, so a runtime without os.link raises :class:~filelock.SoftFileLockProtocolError on acquire. Constructing a singleton again with a different on_compromise, or with poll_interval at or above stale_threshold, now raises :class:ValueError. :pr:735
• :class:~filelock.SoftReadWriteLock exposes :attr:~filelock.SoftReadWriteLock.generation as a fencing token for the protected resource and reports a lost hold through on_compromise and :attr:~filelock.SoftReadWriteLock.compromise. :pr:735
• :class:~filelock.SoftReadWriteLock no longer deadlocks when a holder dies on another host mid-transition, and
