 # Change Log
 
+## 1.2.1 (2020-09-08)
+- Fix bug causing faults to not be displayed in the UI.
+- Fix bug where deleting objects does not get reflected immediately in the UI.
+- Improve conversion between filters written in the expression format and
+MongoDB queries. There should now be fewer edge cases where the two are not
+equisatisfiable.
+
+## 1.2.0 (2020-09-01)
+
+- Support GetParameterAttributes and SetParameterAttributes TR-069 methods.
+- Support CASE statement and COALESCE function in expressions.
+- Provision arguments can now be a list of expressions that are dynamically
+evaluated.
+- Support Forwarded HTTP header to display in the logs the correct IP of CPEs
+behind a reverse proxy. Must be configured using FORWARDED_HEADER option.
+- Config expressions can now access all available device parameters, not only
+serial number, product class, and OUI.
+- Use relative URLs throughout the UI to allow serving from a subdirectory
+using a reverse proxy.
+- Make Date.parse() and Date.UTC() available to provision scripts.
+- libxmljs has been entirely removed in favor of our bespoke XML parser.
+- Removed the config option CWMP_KEEP_ALIVE_TIMEOUT. SESSION_TIMEOUT is now
+used to determine the TCP connection timeout.
+- The all-parameters component now limits the number of parameters displayed
+for better performance.
+- The process genieacs-cwmp is now much less likely to throw exceptions as a
+result of invalid requests from CPE.
+- A large number of bug fixes and stability improvements.
+
 ## 1.2.0-beta.0 (2019-07-30)
 
 - A brand new UI superseding genieacs-gui.

+Administration FAQ
+==================
+
+.. _administration-faq-duplicate-log-entries:
+
+Duplicate log entries when using :func:`log()` function
+-------------------------------------------------------
+
+Because GenieACS uses a full fledged scripting language for device
+configuration, the only way to guarantee that it has satisfied the 'desired
+state' is by repeatedly executing the script until there's no more
+discrepancies with the current device state. Though it may seem like this will
+cause duplicate requests going to the device, this isn't actually the case
+because device configuration are stated declaratively and that the scripts
+themselves are pure functions in the context of a session (e.g. Date.now()
+always returns the same value within the session).
+
+To illustrate with an example, consider the following script:
+
+.. code:: javascript
+
+  log("Executing script");
+  declare("Device.param", null, {value: 1});
+  commit();
+  declare("Device.param", null, {value: 2});
+
+This will set the value of the 'Device.param' to 1, then to 2. Then as the
+script is run again the value is set back to 1 and so on. A stable state will
+never be reached so GenieACS will execute the script a few times until it gives
+up and throws a fault. This is an edge case that should be avoided. A more
+typical case is where the script is run once or twice. Essentially if an
+execution doesn't result in any request to the CPE or a change in the data
+model then a stable state is deemed to have been reached.
+
+Configurations not pushed to device after factory reset
+---------------------------------------------------------
+
+After a device is reset to its factory default state, the cached data model in
+GenieACS's database needs to be invalidated to force rediscovery. Ensure the
+following lines are called on ``0 BOOTSTRAP`` event:
+
+.. code:: javascript
+
+  const now = Date.now();
+
+  // Clear cached data model to force a refresh
+  clear("Device", now);
+  clear("InternetGatewayDevice", now);
+
+
+Most device parameters are missing
+----------------------------------
+
+For performance reasons (server, client, and network), GenieACS by default only
+fetches parts of the data model that are necessary to satisfy the declarations
+in your provision scripts. Create declarations for any parameters you need
+fetched by default.
+
+If you're unsure and want to explore the available parameters exposed by the
+device, refresh the root parameter (e.g. ``InternetGatewayDevice``) from
+GenieACS's UI. You typically only need to do that one time for a given CPE
+model.
