+## v0.3.1 2022-10-25
+
+- Ocaml 5.0 compatible. Thanks to @samoht for the report.
+- tweak ordering implementation in `F.of_list`
+
+## v0.3.0 2019-04-09
+
+Semantics cleanup.
+
+Breaking:
+
+- `find` drops `?promote` and never changes the ordering.
+- `add` drops `?trim` and never drops bindings.
+- `size` -> `weight`
+- `items` -> `size`
+- `unadd` -> `pop`
+- `F.S.fold` and `F.S.iter` iterate in LRU order.
+- `F.M.fold` and `F.M.iter` drop `?dir` and always iterate in LRU order.
+
+Other:
+
+- add `F.S.fold_k` and `F.S.iter_k`
+
+To fix client code:
+
+- replace `find ~promote:false` with `find`;
+- replace `find` and `find ~promote:true` with `find` and `promote`;
+- replace `add ~trim:false` with `add`;
+- replace `add` and `add ~trim:true` with `add` and `trim`;
+- `s/size/weight/g`, `s/items/size/g`, `s/unadd/pop/g`;
+- audit uses of `fold` and `iter` for order-sensitivity.
+
+## v0.2.0 2017-03-31
+
+Breaking changes:
+
+- `resize` no longer drops bindings if the new size pushes the queue over capacity.
+- `of_list` has simpler semantics; dropped the `cap` parameter.
+
+Other changes:
+
+- Replace `Lru.M.cache` with more general `Lru.memo`.
+- Queues with 0 initial capacity are legal.
+- Add `trim` to shrink a queue to its capacity, as queues are no longer guaranteed to
+  have size smaller than capacity.
+- `find` gets the `promote` parameter, allowing queries that do not change the order.
+- `add` gets the `trim` parameter, allowing insertions that do not drop old entries.
