The DatabaseConnection classes have changed. They now encapsulate a PDO object, rather than extend it. A scant few modules used the PDO functions in the DatabaseConnection object, including:
- Database SSL Connection
- All database drivers
Before upgrading to 1.19.0, upgrade these modules to a compatible version or disable them.
If you use a database driver other than the MySQL that ships with Silkscreen core, make sure you update to a compatible version. For PostgreSQL and SQLite, use 1.19.0 or later.
