Jam.py supports deletion and changing of fields, and foreign indexes for SQLITE
database now. As SQLITE doesn’t support column changing and deletion and addition
of foreign indexes to existing tables, Jam.py creates a new table and copies
records into it from old one.
for SQLITE database Jam.py doesn’t support import of metadata to an existing project (project items of
which have corresponding tables in database) now. You can import of metadata to
a new project
BLOB field type renamed to LONGTEXT and corresponding DB field changed from
Blob (if it was) to Long text type wherever possible
