# Filter Bar 4.10.0

Howdy friends! Filter Bar 4.10.0 features updates to the multi-select type filter for the [additional fields](https://docs.nexcess.com/software/the-events-calendar/custom-fields/) feature in Events Calendar Pro so that they now display correctly, as well the ability to change labels for events, venues, and organizers. This is a minor release that should be smooth sailing when updating. That said, it’s always a good idea to [backup](https://docs.nexcess.com/software/the-events-calendar/creating-site-backups/) your site and test changes in a [development environment](https://docs.nexcess.com/software/the-events-calendar/creating-and-using-a-wordpress-staging-site/) before installing this on your live site, as you would with any other WordPress update. Here are the detailed changes included in this release:

- **Tweak** – Select2 3.5.4 is now deprecated in favor of SelectWoo.
- **Tweak** – We now load the plugin text domain on the new tribe\_load\_text\_domains action hook, which fires on init instead of on the plugins\_loaded hook. This allows for custom translations to be loaded correctly.
- **Fix** – This fix prevents PHP errors from happening during bulk activation or deactivation of the plugin.
- **Fix** – We have updated events, venues, and organizers to use dynamic labels, so that they have the ability to be changed with this [handy extension](https://docs.nexcess.com/software/the-events-calendar/customize-venues-organizers/).
- **Fix** – Using the multi-select type filter for Event Calendar Pro’s additional fields no longer displays unnecessary options.
- **Hooks** – [https://docs.theeventscalendar.com/reference/since/events.filterbar4.9.3/](https://docs.theeventscalendar.com/reference/since/events.filterbar4.9.3/)
- **Language** – 2 new strings added, 34 updated, 3 fuzzied, and 6 obsoleted
