 # Change Log
 
-## 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.
