WordPress 5.3 Compatibility?

I’ve been using the dsIDXPress plugin on WordPress 5.2.4 and PHP 7.2 successfully for a while, but I’d like to upgrade to WordPress 5.3, and currently, the dsIDXPress plugin shows it’s only tested up to v. 5.1.3.

I checked the code and found the following issues:

FILE: ...c_html/wp-content/plugins/dsidxpress/widget-idx-quick-search.php
----------------------------------------------------------------------
FOUND 0 ERRORS AND 1 WARNING AFFECTING 1 LINE
----------------------------------------------------------------------
 352 | WARNING | Function each() is deprecated since PHP 7.2; Use a
     |         | foreach loop instead
----------------------------------------------------------------------

----------------------------------------------------------------------

----------------------------------------------------------------------
FOUND 0 ERRORS AND 1 WARNING AFFECTING 1 LINE
----------------------------------------------------------------------
 3 | WARNING | Use of deprecated PHP4 style class constructor is not
   |         | supported since PHP 7.
----------------------------------------------------------------------

Since those are just warnings for deprecated functions and not errors, none of them should prevent dsIDXPress from running with WordPress 5.3 and PHP 7.2, but I have no way of checking beyond that to see if any of the changes in WordPress 5.3 might break something other than going ahead with the upgrade. Before I upgrade a production site, can you tell me if it’s compatible with 5.3?
