+politeia v1.3.0
+====
+
+This release includes the following additions and improvements. See the
+changelog for the full list of changes.
+
+- **Preps the codebase for the user layer rewrite.** The majority of the LOC
+  changes made in this release are changes made in preparation for the user
+  layer rewrite. This includes pulling apart code and separating concerns that
+  were too tightly coupled with the legacy code and moving all of the legacy
+  code into a `legacy` package that will be removed at some point in the
+  future.
+
+- **Improves the billing status API.** Billing statuses were updated to allow
+  for error correction. By default, only a single billing status change is
+  allowed. This is now configurable by the sysadmin to allow for error
+  correction in the event that an admin makes a mistake when updating a
+  proposal's billing status.
+
+- **Parallelize politeiavoter trickling.** The user now has the option to
+  parallelize their vote trickling using up to 100 concurrent threads. The
+  threads will start trickling votes in at random, uncorrelated times, further
+  improving privacy and making the trickling process more robust.
+
+**Note: You must update your politeiavoter binary if you use the politeiavoter
+trickling feature. Retry attempts for failed votes will not work properly if
+you do not update.**
