Your Question

In v1.0, I've used gorm:query_option to do a locking read, as in:

db = db.Set("gorm:query_option", "FOR UPDATE")
db.Where("ID = ?", id).First(&customer)

This still compiles in v2 but has no effect and leads to subtle bugs.

Expected answer

Please add this issue to the migration guide and point to the documentation on locking reads.

this feature is not documented in v1, so it is not mentioned in the release note.
