+# v2.0 (TBD)
+
+**Backwards-incompatible changes:**
+- The configuration format has changed slightly to be more consistent with itself.
+  Refer to the README for details. The following things have changed in particular:
+  - `jobs[].from` becomes `jobs[].from.url` (unless it is an object already).
+  - `jobs[].to` is split into `jobs[].to.container` and `jobs[].to.object_prefix`.
+  - `jobs[].{ca,cert,key}` move into `jobs[].from`.
+
+New features:
+- swift-http-import can now transfer large objects by using the Static Large Object method of Swift. The
+  `jobs[].segmenting` configuration section must be specified to enable segmenting.
+- When transfering files from a Swift source, swift-http-import will now recognize objects with an expiry timestamp, and
+  mirror the expiry timestamp to the target side. The `jobs[].expiration` configuration section can be used to control
+  this behavior.
+
+Bugfixes:
+- Interrupts (SIGTERM and SIGINT) are now ignored less often.
+
