+Release Notes v2.8.1
+====================
+
+This release introduces worker-based updates for expensive submission state 
+computation. It offloads work from the main web loop when processing 
+incoming messages so responses are quicker.
+
+When deploying to production, make sure to size both instances and worker 
+concurrency so that, you don't use up all available compute cores and not 
+use enough making updates very slow.
+
+Bugs
+----
+
+* made a correction on which column the percentage of valid votes is displayed
+* removed extraneous permission defaults
+* set the submission comment deployment before it is saved
+* fixed the output of the byte-order mark in file exports
+
+Features
+--------
+
+* switched to using alpine linux v3.7
+* added management command for setting up default permissions
+* added indexes for sortable columns in the participants list

+====================
+
+This minor release fixes a few bugs with data imports with the major 
+bug fix having to do with an issue where subsequent participant data 
+uploads simply added more data to the phone number field rather than 
+replacing what was previously there.
+
+Bugs
+----
+
+* clear phones when uploading new data (#266)
+* force sync before running supervisor linking pass (#171)
+* supply deployment and phone number for background update of 
+  submissions (#173)
