 We are pleased to announce another successful year of [Google Summer of Code][] with the [NumFOCUS][] organization,
 thanks to [Richard Gowers][] and [Jonathan Barnoud][] for mentoring the GSoC students.
-This year one of the projects was [to improve the performance of pairwise distance computations][], which is used quite frequently in MDAnalysis in different forms.

 MDAnalysis v0.19.0 and higher now include the _new functions [`MDAnalysis.lib.distances.capped_distance`][] and [`MDAnalysis.lib.distances.self_capped_distance`][]_
 which offer a much faster way to calculate all pairwise distances up to a certain maximum distance.
