+# v0.6.0 (unreleased)
+
+* *(dbutil)* Added `-- transaction: sqlite-fkey-off` mode to upgrades, which
+  allows safer upgrades that disable foreign keys without having to disable
+  transactions entirely.
+  * **Breaking change:** `UpgradeTable.Register` now takes a TxnMode instead
+    of a bool as the 5th parameter.
+  * **Breaking change:** `Database.DoTxn` now takes `*dbutil.TxnOptions`
+    instead of `*sql.TxOptions`. `nil` is still allowed and the existing fields
+    are still supported, but there's a new field too.
+  * **Breaking change:** `Database.Conn` was renamed to `Execable` to avoid
+    confusion with the new `AcquireConn` method (`Execable` just returns the
+    current transaction or database, `AcquireConn` acquires a connection for
+    exclusive use).
+* *(dbutil)* Added finalizer for RowIter to panic if the rows aren't iterated.
+* *(dbutil)* Changed `QueryOne` to return a zero value (usually nil) if the
+  `Scan` method returns an error.
+* *(progress)* Implemented `io.Seeker` in `Reader`.
+* *(ptr)* Added new utilities for creating pointers to arbitrary values, as
+  well as safely dereferencing pointers and making shallow clones.
+* *(exslices)* Added functions to cast slices to different types.
+* *(gnuzip)* Added wrappers for gzip that operate on `[]byte`s instead of
+  `io.Reader`/`Writer`s.
+* *(lottie)* Added wrapper for [lottieconverter] similar to ffmpeg.
