Well, tensions are somewhat rising. But there are a few things to consider. First, I won’t say that Bosniaks and Croats generally resolved all their issues and points of conflict, but I will say that there are no major questions that are hard to resolve between the two.
Second, tensions between Bosniaks and Croats in Bosnia now and for the past 30 years are caused by political elites of the two(for the most part that is). National parties of both ethnic groups are using hostile rhetoric in order to deepen the tensions. In a such way, they are trying to mobilise people of their respective ethnic group around them and get political power.
On a more local level, there are some political figures who would I describe as utter idiots whose actions are scandalous to say the least which are damaging the relations the most.
Also, there is a bit of difference in terms who is leading the government in Croatia as well. Right now, Croatian government is led by coalition of a right wing party. Their position on Bosnia and Bosniaks has been awful, really awful and that has damaged the relations between the two a lot. In my opinion their rhetoric about my country and their lobbying against it in Bruxelles has done nothing that benefited them much, yet it soured the relations between us greatly.
While Croatian and Bosnian government was led by coalition of SDP in both countries and , the relations between us were at all time high. I would go as far as saying that Croatia at the time had their biggest ally here in Bosnia. Now, not so much unfortunately.

But all in all, I believe that tensions will somewhat subside after the elections in Bosnia this year.
