I think XML parser is still broken. It affects sitemaps and RSS feeds. Issue was reported a long ago and still no fix. Was working well several versions ago. Would anyone track, what changed since then and what to roll back or fix to have xmls working again?
I slowly start accepting the variant that there will be no response nor action from developers any time. No one touched github for months. PRs hanging there for long long time, no one responds in forum. @orbiter left this world?
