Unfortunately a few hours on http://software.pureos.net/package/source/landing/fontconfig is not showing -5 as being in landing or green. There is no reason why it shouldn't migrate if -4 is already there (no change of dependencies AFAICT). Can you help?
@chris.lamb Be patient ;-) Migrating a completely new package taes at least two dinstall runs, so a few hours was just not enough time ^^
@d3vid The website takes a few minutes to update after a new package has been published, so you might have caight the new package immediately after it was migrated, but before it was actually registered in the database as being in green as well.
