Migration Add API Broken

[jemtucker]

In version 1.2.15 the Migration.Add API has breaking changes that make it no longer usable.

I have been using migrations in Go like so:

ms.Add(migrate.Migration{
		Name:    "20241024-initial-migration",
		Comment: "init first model",
		Up: func(ctx context.Context, db *bun.DB) error {
           ...
        },
        Down: func(ctx context.Context, db *bun.DB) error {
           ...
        },
})

Since d92e29e this is no longer possible due to a private type being used in the definition of the Up and Down members.

Is there a migration path (pun not intended) from Add to Register that won't break compatibility with migrations that have already been run?

The Add API is currently documented on the main web page here https://bun.uptrace.dev/#migrations-that-scale in a way that will no longer compile with these changes too

func init() {
    migrations.Add("20230101_create_users", func(ctx context.Context, db *bun.DB) error {
        _, err := db.NewCreateTable().
            Model((*User)(nil)).
            IfNotExists().
            Exec(ctx)
        return err
    }, func(ctx context.Context, db *bun.DB) error {
        _, err := db.NewDropTable().
            Model((*User)(nil)).
            IfExists().
            Exec(ctx)
        return err
    })
}
