# Mp3tag v3.22 released
I've just released Mp3tag v3.22 and wanted to outline some of the new features and changes:
### Configuration Settings for Tag Sources
This feature was a huge undertaking. It allows Tag Sources Developers to define configuration settings for their Tag Sources, which, in turn, are used by Mp3tag to both generate a configuration dialog and in the Tag Source itself. This means no more manual editing of Tag Sources, which was both tedious to keep updated and prone to errors. I've added [lots of documentation](https://docs.mp3tag.de/tag-sources/development/) to get you started.
Thanks to @stevehero for the initial suggestion and continuous feedback, @AreDigg for feedback and early adoption, and all who tried and supported this feature during the beta phase.
### Checkbox fields on Tag Panel
It's now possible to define checkbox fields to the Tag Panel. This can be useful for certain fields where the only valid input is `1`, e.g., for `COMPILATION` and `PODCAST`. I've also added a new _Type_-selector, which now lists the different supported field types _Text_, _Check_, and _Multiline_.
### More JSON-related functions for Web Sources Framework
The focus was clearly on Tag Sources with this release. The Web Sources Framework got many new JSON-related functions, which should make developing JSON-based Tag Sources a breeze (or at least more like that).
- `json_select_many` has new options for last item separator and maximum items to select,
- `json_select_many_count` to emit the number of objects a JSON array, or objects with a certain element,
- `json_foreach_counter` to emit the current counter of iteration via `json_foreach` or `json_foreach_reverse`,
- `json_foreach_reverse` to start iteration over an JSON array in reversed order,
... and one general-purpose function `SayDuration` which converts a given number to a formatted duration string.

I've just released **Mp3tag v3.22b** , which fixes an issue introduced with v3.22a, where extracting cover art opened the last used folder instead of the current folder.
