### Bugs/Housekeeping:
* Port preferences dialog to React.

* Fixed an issue where SQL for revoke statements were not shown for databases.
* Adds a new LDAP authentication configuration parameter that indicates the case sensitivity of the LDAP schema/server.
* Ensure that the master password dialog is popped up if the crypt key is missing.
* Fixed an issue where foreign key relationships do not update when the primary key is modified.
* Ensure that objects depending on extensions are not displayed in Schema Diff.
* Fixed an issue where foreign key is not removed even if the referred table is removed in ERD.
* Fixed schema diff issue where function's difference DDL was showing incorrectly when arguments had default values with commas.

**Note**: This release includes an LDAP configuration change related to the case insensitivity support for DNS. By default during a bind request, the LDAP DN is now treated case-insensitively. If you want to make it case-sensitive to return to the previous behavior, set the LDAP config setting LDAP_DN_CASE_SENSITIVE to True.

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/).
