| 20 |
* What was done ( by Elementor): |
| 21 |
* Reformat of the code. |
| 22 |
* Changed text domain. |
| 23 |
* Changed methods visibility. |
| 24 |
* Changed method from `get_authors_from_import` to `set_authors_from_import`. |
| 25 |
* Changed method from `get_author_mapping` to `set_author_mapping`. |
| 26 |
* Removed use of '$_POST' the input 'options' will be passed via constructor args. |
| 27 |
* Removed echos, UI and print methods, all echos replaced with `$this->output` append. |
| 28 |
* Removed `die` ( exit(s) ). |
| 29 |
