+Bugfix: List snapshots in backend at most once to resolve snapshot ids
+
+Many commands support specifying a list of snapshot ids which are then used to
+determine the snapshot accessed by the command. To resolve snapshot ids or
+"latest" and check that these exist, restic listed all snapshots stored in the
+repository. Depending on the backend this can be a slow and/or expensive
+operation.
+
+Restic now lists the snapshots only once and remembers the result to resolve
+all further snapshot ids.

+Bugfix: Fix rare 'not found in repository' error for copy command
+
+In rare cases copy (and other commands) could report that LoadTree(...)
+returned a `id [...] not found in repository` error. This could be caused by a
+backup or copy command running concurrently. The error is only temporary,
+running the failed restic command a second time as a workaround solves the
+error.
+
+This issue has been fixed by correcting the order in which restic reads data
+from the repository. It is now guaranteed that restic only loads snapshots for
+which all necessary data is already available.
