We study the jumps of topological entropy for $C^{r}$ interval or circle maps. We prove in particular that the topological entropy is continuous at any $f ∈ C^{r}([0,1])$ with $h_{top}(f) > (log⁺||f'||_{∞})/r$. To this end we study the continuity of the entropy of the Buzzi-Hofbauer diagrams associated to $C^{r}$ interval maps.
