As MartinK pointed out in modRana thread (https://talk.maemo.org/showpost.php?...postcount=2013), there is an ongoing work on updating QtLocation. I have asked whether new packages would include MapboxGL plugin and got a reply - no. See discussion at https://git.merproject.org/mer-core/...ge_requests/15

Looks like its induced by old gcc. From this I expect that no major gcc is coming for SFOS 3. I wonder why they don't use neochapay's packaging of gcc?

Anyway, the situation with the respect of MapboxGL plugin is more clear now.
