 New features:
 
+- add BORG_CACHE_IMPL, default is "adhocwithfiles" to test the new cache
+  implementation, featuring an adhoc non-persistent chunks cache and a
+  persistent files cache. See the docs for other values.
+
+  Requires to run "borg check --repair --archives-only" to delete orphaned
+  chunks before running "borg compact" to free space! These orphans are
+  expected due to the simplified refcounting with the AdHocFilesCache.
