---

3.31.0 (2026-07-18)

---

• Support Termux/Android, whose CPython ships without os.link and reports sys.platform == "android". import filelock and both FileLock and SoftFileLock now work there, StrictSoftFileLock reports its missing hard-link support only when acquired, and process liveness reads /proc on Android instead of PID-only checks. :pr:678
• StrictSoftFileLock no longer lets two processes hold the lock at once under heavy contention. A holder now keeps its intent claim for the whole hold, so a contender whose directory scan races the holder's freshly linked claim can no longer miss it and win alongside it. A held lock now exposes both an intent and a held claim. :pr:678

---

3.30.3 (2026-07-17)

---

• AsyncFileLock and AsyncSoftFileLock no longer raise a deadlock RuntimeError when a different asyncio task waits for a lock they hold; the check now scopes holders to the owning task, so only a same-task reacquire is refused. :pr:676
• Keep both tables of contents on screen at any browser font size. The widened body column sized itself in em against the reader's font size while the breakpoints that fold the layout resolve em against a fixed 16px, so a reader whose default font is larger than 16px had the right-hand table of contents clipped off the edge. The body column now flexes instead, and the right-hand table of contents hides only at the mobile breakpoint. :pr:673
• Color the mermaid diagrams from whichever theme is active. They previously carried a light palette baked into each diagram's source, which stayed light on a dark page. :pr:674

---

3.30.2 (2026-07-16)

---

• Stop :class:~filelock.SoftFileLease deleting a live marker whose mode it does not implement. An unrecognized mode now names its owner instead of reading as malformed, so a record written by a newer filelock survives the grace window rather than being evicted after two seconds. :pr:672
• Stop :class:~filelock.StrictSoftFileLock and :class:~filelock.AsyncStrictSoftFileLock calling themselves a native OS lock when they warn that they ignore lifetime; they now say a strict claim is only ever cleared by force_break(). :pr:672
• Cover every lock type in the tutorials and how-to guides, with examples drawn from projects that use filelock, and color the mermaid diagrams. Correct the claims that StrictSoftFileLock exposes owner, that :class:~filelock.SoftFileLock evicts a strict sentinel, that :class:~filelock.ReadWriteLock requires a .db extension, and that every log record is DEBUG. :pr:672

---

3.30.1 (2026-07-16)

---

• StrictSoftFileLock and AsyncStrictSoftFileLock no longer abort acquisition when a peer's claim vanishes as an NFSv3 stale filehandle instead of a clean removal; the reader revalidates and skips it, so strict locks hold mutual exclusion across independent NFSv3 client caches. :pr:669
• SoftFileLease reads a marker whose lease duration is nan or inf as malformed rather than as a valid lease, so such a marker ages out through the grace window instead of raising LeaseSettingsMismatch on every contender. :pr:670
