 # Change Log
 
-## 1.2.5 (2021-03-12)
-
-- Support specifying custom types when uploading files.
-- Fix JS compatibility issue with Safari browser.
-
-## 1.2.4 (2021-02-24)
-
-- The data model state of a CPE is no longer forgotten after unsuccessful
-  session termination (e.g. timeout). This addresses a number of undesired side
-  effects that arise when a CPE does not terminate the session properly.
-- Executing tasks that take a long time to complete (e.g. refreshing the entire
-  data model) no longer shows a timeout error while the task is still being
-  processed.
-- New function `ROUND()` available to expressions. It works similar to the
-  function by the same name in SQLite and PostgreSQL.
-- Log access events for `genieacs-nbi` service.
-- Pipe stdout/stderr from extension scripts to the `genieacs-cwmp` process log.
-- Parameter values of type `xsd:dateTime` are now displayed in the UI and CSV
-  downloads as a date string rather than a numeric value.
-- Add file download link in the files listing page.
-- Display spinner loading animation throughout the UI.
-- Display GenieACS version and build number underneath the logo.
-- New option to specify how many parameters are displayed at a time in the
-  all-parameters component. Simply set `limit` property in the component config.
-- Reduce overly strong Brotli compression level which was causing significant
-  page load slowdown when Brotli is used.
-- Retire dump-data-model tool. `genieacs-sim` can now use a CSV file as its data
-  model.
-- Reduce the number of concurrent database connections from each process.
-- Remove dependency on 'hostInfo' MongoDB command which is a privileged action.
-  It is now possible to use shared MongoDB instances with limited privileged.
-- Fix bug in NBI where querying files returns 404 error.
-- Fix ping not working for devices with an IPv6 address.
-- Fix an elusive memory leak in `genieacs-fs` that slowly eats up memory and can
-  go unnoticed for long periods of time.
-- Fix a rare edge case where a `declare()` call to set a parameter value may not
-  work as intended if the parameter was originally received as part of the
-  Inform message.
-- A number of other fixes and stability improvements.
-
-## 1.2.3 (2020-10-26)
-
-- New config option 'cwmp.skipWritableCheck' for when some CPEs incorrectly
-  report writable parameters as non-writable. When set to true, the scripts will
-  no longer respect the 'writable' attribute of the CPE parameters and will send
-  a SetParamteerValues, AddObject, or DeleteObject request anyway.
-- Tags no longer restrict what characters are allowed. Any character other than
-  alphanumeric characters, hyphen, or underscore is now encoded in the data
-  model (i.e. Tags.\<tag>) using its hex value preceded by "0x".
-- Ask for a confirmation before closing a pop-up dialog with unsaved changes.
-- Better XML validation to avoid crashes caused by invalid CPE requests.
-- Fix confusing 404 error message when the user attempts to modify a resource
-  when they don't have the necessary permissions.
-- Fix a rare issue where genieacs-cwmp stops accepting new connections after
-  running for a few weeks.
-- Fix exception when IS NULL operator is used in certain situations.
-
-## 1.2.2 (2020-10-03)
-
-- Added button to push files to selected devices from device listing page.
-- A few minor UI improvements.
-- Fix exception that can happen and persist after a Download request.
-- Fix validation bug preventing running refreshObject task on data model root.
-- Fix invalid arguments fault in refresh preset configuration when upgrading
-  from v1.1.
-
-## 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.
 - New initialization wizard on first run.

 CPE Authentication
 ==================
 
-CPE to ACS
-----------
-
-.. note::
-
-  By default GenieACS will accept any incoming connection via HTTP/HTTPS and
-  respond to it.
-
-The following parameters are used to set and get (password is redacted but
-can be set) the username/password used to authenticate against the ACS:
-
-Username: ``Device.ManagementServer.Username`` or ``InternetGatewayDevice.ManagementServer.Username``
-
-Password: ``Device.ManagementServer.Password`` or ``InternetGatewayDevice.ManagementServer.Password``
-
-Enable CPE to ACS Authentication
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-CPE to ACS authentication can be configured in the web interface by using the
-`Config` option in the `Admin` tab.
-
-Go to the `Admin` -> `Config` page and click on `New config` button at the
-bottom of the page. This will open pop-up which requires you to fill in a key
-and value. The key should be ``cwmp.auth``. The value accepts a boolean.
-Setting the value to ``true`` makes it so that GenieACS accepts any incoming
-connection, setting it to ``false`` makes GenieACS deny all incoming
-connections. This can be further configured using the ``AUTH()`` and ``EXT()``
-functions.
-
-The ``AUTH()`` function
-~~~~~~~~~~~~~~~~~~~~~~~
-
-The ``AUTH()`` function accepts two parameters, username and password. It
-checks the given username and password with the incoming request to determine
-whether to return true or false.
-
-Basic usage of the ``AUTH()`` function could be as follows:
-
-.. code:: sql
-
-   AUTH("fixed-username", "fixed-password")
-
-This will only accept incoming request who authenticate with
-"fixed-username" and "fixed-password".
-
-The various device parameters can be referenced from within the ``cwmp.auth``
-expression. For example:
-
-.. code:: sql
-
-   AUTH(Device.ManagementServer.Username, Device.ManagementServer.Password)
-
-The ``EXT()`` function
-~~~~~~~~~~~~~~~~~~~~~~
-
-The ``EXT()`` function makes it possible to call an :ref:`extension
-<extensions>` script from the auth expression. This can be used to fetch
-the credentials from an external source:
-
-.. code:: sql
-
-   AUTH(DeviceID.SerialNumber, EXT("authenticate", "getPassword", DeviceID.SerialNumber))
