Please make sure that the issues I've mentioned in this issue are fixed prior to bumping the version.

Note that I've recently changed the doxygen link to a mirror: #422

[d3m3vilurr]

omg.... do you really think making artifacts is good idea?

okay. changed mind. if we weren't able to access the binary link, we have to make the internal mirror.
but in the normal case, we don't need it :)

@d3m3vilurr It's always a good thing to keep your dependency on your side ;)

[d3m3vilurr]

@yne but also that is totally annoying thing.
if we had to always need to maintain the every dep tree, I try to find the package manager instead making the manual binary mirror.
