+* Fix `bin/rails db:migrate` with specified `VERSION`.
+ `bin/rails db:migrate` with empty VERSION behaves as without `VERSION`.
+ Check a format of `VERSION`: Allow a migration version number
+ or name of a migration file. Raise error if format of `VERSION` is invalid.
+ Raise error if target migration doesn't exist.

+ *bogdanvlviv*

* Fixed a bug where column orders for an index weren't written to
db/schema.rb when using the sqlite adapter.
