Created attachment 139438 [details] digiKam unable to display newer KRA file's thumbnail/preview/metadata digiKam is current unable to display thumbnails or previews for the newer versions of KRA (Krita) documents. It doesn't even decode any of those KRA file's metadata. It can still decode my older KRA files. The last showing KRA file is Krita 4.3's splash saved at 2020-04-30. The next file was saved at 2020-09-14, and it is not decoded. I think Krita updated its document format in a (not really that) recent version. It could be Krita 4.3.0 released in 2020-06-18, or 4.4.0 released in 2020-10-13. Maybe digiKam's related libraries are out of date? Tested with appimage and Windows version of 7.2.0 and 7.3.0 nighties.
The Krita format is loaded by the KImageFormats plugins. Krita only uses a new ZIP code and now the bytes required to recognize the format are no longer found. There's a bug report on KImageFormats, I'm looking for ... Maik
