 ## Changelog
 
-- 0.0.1 - Unreleased
+- 0.0.47 - 29.06.2020
+  - Update to `Get-GPOZaurrAD` for better error reporting
+  - Updates to `Invoke-GPOZaurr` - still work in progress
+- 0.0.46 - 28.06.2020
+  - Additional protection for `Get-GPOZaurrAD` for CNF duplicates
+  - Update to `Save-GPOZaurrFiles`
+  - Added `Invoke-GPOZaurr` (alias: `Find-GPO`) (heavy work in progress)
+- 0.0.45 - 26.06.2020
+  - During publishing ADEssentials required functions are now merged to prevent cyclic dependency bug [Using ModuleSpec syntax in RequiredModules causes incorrect "cyclic dependency" failures](https://github.com/PowerShell/PowerShell/issues/2607)
+- 0.0.44 - 24.06.2020
+  - Improvement to `Get-GPOZaurrLinkSummary`
+- 0.0.43 - 21.06.2020
+  - Added `Get-GPOZaurrFiles` to list files on NETLOGON/SYSVOL shares with a lot of details
+- 0.0.42 - 19.06.2020
+  - Fix for `Get-GPOZaurrLink` and `SearchBase` parameter
+  - Fix for `Get-GPOZaurrLink` - canonical link Trim() throwing errors if empty
+- 0.0.41 - 18.06.2020
+  - Added paramerter `SkipDuplicates` to `Invoke-GPOZaurrPermission` which prevents applying permissions over and over again if 1 GPO is linked to a multiple OU's within another OU
+- 0.0.40 - 18.06.2020
+  - Fix for error `Get-GPOZaurrLink` - same issue as described on my [earlier blog - Get-ADObject : The server has returned the following error: invalid enumeration context.](https://evotec.xyz/get-adobject-the-server-has-returned-the-following-error-invalid-enumeration-context/).
+    - `WARNING: Get-GPOZaurrLink - Processing error The server has returned the following error: invalid enumeration context.`
+    - `WARNING: Get-GPOZaurrLink - Processing error A referral was returned from the server`
+  - Added `SkipDuplicates` for `Get-GPOZaurrLink`
+- 0.0.39 - 17.06.2020
+  - Updates to `Invoke-GPOZaurrPermission` with new parameter `LimitAdministrativeGroupsToDomain`
+    - This will get administrative based on IncludeDomains if given. It means that if GPO has Domain admins added from multiple domains it will only find one, and remove all other Domain Admins (if working with Domain Admins that is)
+- 0.0.38 - 17.06.2020
+  - Update to Get-PrivGPOZaurrLink which would cause problems to `Invoke-GPOZaurrPermission` if it would be run without Administrative permission and GPO wouldn't be accessible for that user
+- 0.0.37 - 16.06.2020
+  - Updates to `Invoke-GPOZaurrPermission` with new parameterset `Level`
+  - Updates to `Get-GPOZaurrLinkSummary`
+- 0.0.36 - 15.06.2020
