Deprecated: Use of Parser::$mDoubleUnderscores was deprecated in MediaWiki 1.35. [Called from Lingo\LingoParser::shouldParse in ..\mediawiki\extensions\Lingo\src\LingoParser.php at line 391]
I'm currently upgrading MW from 1.35 to 1.39 and now receive this deprecation notice. Will this be fixed in time for the stable release?
