<a href="http://blog.gingerlime.com/ajaxizing/" title="WordPress plugin that allows you to ajaxize almost any php function on your site" rel="nofollow ugc">Ajaxize</a> will allow you to ajaxize almost any php function on your site. 
It can be a plugin, a function you wrote, or even a core wordpress function.
1.4 : Removed deprecated split function 
 Added an option to remove Ajax referer protection (not recommended, but helpful in some rare cases) 
 Tested for compatibility with WordPress 4.x
1.3 : Updated to work within 404 templates (thanks to ovidiubica for reporting)
1.2 : Small security improvements (added nonce to the javascript) and tested with WordPress 3.2.1
New in 1.1: Context Awareness. Ajaxize is now setting the correct context for functions automatically. Special thanks to <a href="http://digitalnature.eu/" rel="nofollow ugc">One Trick Pony</a> for helping set the hook in the right place.

ACF: Dynamic Year Select Field

Great ACF plugin. Couple of little bugs, e.g. in the Edit Field Group page this field trys to stop the Update button action by saying that the page has changed when it shouldn't. Also this field isn't compatible by the ACF Add-on for Admin Columns Pro which means that this field can't be edited using Admin Columns Pro Inline Edit function.

Good little plugn

Adds a dynamic year select option for Advanced Custom Fields.
