- Created new FILE_ARCHIVER package (v3.2.1) for managing file archival processes, including procedures for archiving, restoring, and purging files. - Added versioning and build information to the package with detailed version history. - Enhanced A_SOURCE_FILE_CONFIG table by adding ARCHIVE_ENABLED and KEEP_IN_TRASH columns to control archival participation and TRASH retention policy. - Implemented constraints and comments for new columns to ensure data integrity and provide clarity on their usage.
