The pgAdmin Development Team is pleased to announce pgAdmin 4 version 6.16. This release of pgAdmin 4 includes 28 bug fixes and new features. For more details please see the [release notes](https://www.pgadmin.org/docs/pgadmin4/6.16/release_notes_6_16.html).

pgAdmin is the leading Open Source graphical management tool for PostgreSQL. For more information, please see [the website](https://www.pgadmin.org/).
Notable changes in this release include:

### Features:
* Added support for storing configurations of pgAdmin in an external database.

Use the external database server to save the pgAdmin 4 user settings in situations where SQLite is not preferred. It is useful when adding HA support for the configuration database or to avoid using SQLite on non-ephemeral storage.

* Added the ability to generate ERDs for tables.

* Add the possibility to configure the Oauth2 claim which is used for the pgAdmin username.

### Bugs/Housekeeping:
* Fixed an issue where the screen was freezing while closing the wcDocker panel.
* Ensure that autocomplete works properly with objects starting with double quotes.
* Ensure that pgAdmin routes should have the SCRIPT_NAME prefix.
* Ensure that the appropriate permissions are set on the key file before trying an SSL connection with the server in server mode.
* Fixed an issue where the result grid was not working properly while trying to edit data by hitting Enter key.
* Fixed an issue where AutoComplete was not working correctly due to incorrect regex.
* Fixed an issue where the 'Confirm on close or refresh' setting was ignored when closing the query/ERD tool opened in the new tab.
* Fixed an issue where pgadmin does not respect reverse proxy anymore.
* Ensure that the load file paths are children of the storage directory.
* Use the shared server username when opening the query tool.

Builds for Windows and macOS are available now, along with a Python Wheel, Docker Container, RPM, DEB Package, and source code tarball from the [tarball area](https://www.pgadmin.org/download/).
