+[2.0.0] - 12/9/2019
+-------------------
+
+::
+
+ * Implements new logic around when instances are deleted. See flowcharts in docs/. Basically timeouts now trigger to actually delete instances from a1s database, and these timeouts are configurable.
+ * Eliminates the barrier to deleting an instance when no xapp evdr replied (via timeouts)
+ * Add two new ENV variables that control timeouts
+ * Make unit tests more modular so new workflows can be tested easily
+ * Fixes the API for ../status to return a richer structure. This is an (albeit tiny) API change.
+ * Clean up unused items in the integration tests helm chart
+ * Removed "RMR_RCV_RETRY_INTERVAL" leftovers since this isn't used anymore
+ * Uses the standard RIC logging library
+ * Switch the backend routing scheme to using subscription id with constant message types, per request.
+ * Given the above, policy type ids can be any valid 32bit greater than 0
+ * Decouple the API between northbound and A1 from A1 with xapps. This is now two seperate OpenAPI files
+ * Update example for AC Xapp
+ * Updgrade rmr and rmr-python to utilize new features; lots of cleanups because of that
+ * Implements a POLICY QUERY feature where A1 listens for queries for a policy type. A1 then responds via multiple RTS messages every policy instance of that policy type (and expects an ACK back from xapps as usual). This feature can be used for xapp recovery etc.
+
+[1.0.4]
+-------
+
+::
+
+ * Only external change here is to healthcheck the rmr thread as part of a1s healthcheck. k8s will now respin a1 if that is failing.
+ * Refactors (simplifies) how we wait for rmr initialization; it is now called as part of __init__
+ * Refactors (simplifies) how the thread is actually launched; it is now internal to the object and also a part of __init__
+ * Cleans up unit testing; a1rmr now exposes a replace_rcv_func; useful for unit testing, harmless if not called otherwise
+ * Upgrades to rmr-python 1.0.0 for simpler message allocation
+
+[1.0.3] - 10/22/2019
+--------------------
+
+::
+
+ * Move database cleanup (e.g., deleting instances based on statuses) into the polling loop
+ * Rework how unit testing works with the polling loop; prior, exceptions were being thrown silently from the thread but not printed. The polling thread has now been paramaterized with override functions for the purposes of testing
+ * Make type cleanup more efficient since we know exactly what instances were touched, and it's inefficient to iterate over all instances if they were not
+ * Bump rmr-python version, and bump rmr version
+ * Still an item left to do in this work; refactor the thread slightly to tie in a healthcheck with a1s healthcheck. We need k8s to restart a1 if that thread dies too.
+
+[1.0.2] - 10/17/2019
+--------------------
+
+::
+
+ * a1 now has a seperate, continuous polling thread
+ this will enable operations like database cleanup (based on ACKs) and external notifications in real time,
+ rather than when the API is invoked
+ * all rmr send and receive operations are now in this thread
+ * introduces a thread safe job queue between the two threads
+ * Not done yet: database cleanups in the thread
+ * Bump rmr python version
+ * Clean up some logging
+
+[1.0.1] - 10/15/2019
