+## Upgrading to v1.5.0 (pending)
+
+### `SecureString` and Icinga Director Baskets
+
+We have updated the configuration baskets generator to set arguments defined as `SecureString` (for passwords) to `hidden` within the Icinga Director. This will prevent users from simply gaining access to a password while having access to the Director.
+
+Please update manually all your CustomFields under `Icinga Director` -> `Define Data Fields` -> Search for `*_Securestring_*` -> Field `Visibility` to `Hidden` before importing new configuration baskets. Otherwise you will have two data fields stored within your Icinga Director and have to enter all passwords again for your service checks.

 ## Upgrading to v1.4.0 (2021-03-02)
 
 The pre-compiled configurations for each module and the result of `Get-IcingaCheckCommandConfig` have been changed. In order to use the new CheckCommand definitions for Icinga 2 you will **require** to update your entire environment to Icinga for Windows v1.4.0 **before** using the new configuration files!

 ### Enhancements
 
+* [#229](https://github.com/Icinga/icinga-powershell-framework/pull/229) CustomFields defined as `SecureString` are now set to `hidden` within the Icinga Director configuration basket - please read the [upgrading docs](30-upgrading-framework.md) carefully
 * [#234](https://github.com/Icinga/icinga-powershell-framework/pull/234) Adds support to allow custom exception lists for Icinga Exceptions, making it easier for different modules to ship their own exception messages
 * [#235](https://github.com/Icinga/icinga-powershell-framework/pull/235) Adds new Cmdlet `Show-IcingaEventLogAnalysis` to get a better overview on how many log entries are present within the EventLog based on hour, minute and day average/maximum for allowing a more dynamic configuration for `Invoke-IcingaCheckEventLog`
