Any update possible for Mediawiki 1.39 and SMW 4.1.1 ?

[HQ1791]

I have downloaded the branch 59-make-work-with-mw-1.34 and installation run smooth and Special:RDFIO-Admin setup works. However, the other 3 RDFIO special pages looks fine until press button they throw error.

Also, on SPARQL Endpoint i get these warnings

`Warning: Undefined property: ARC2_StoreEndpoint::$getErrors in C:\xampp\htdocs\mediawiki2\extensions\RDFIO\specials\SpecialSPARQLEndpoint.php on line 141

Warning: foreach() argument must be of type array|object, null given in C:\xampp\htdocs\mediawiki2\extensions\RDFIO\classes\RDFIO_SpecialPage.php on line 150
`
Any update would be appreciated. Thanks!
