According to the source code repository and the distribution files of Heimdal, the project has released 1.5.3: http://www.h5l.org/dist/src/ https://github.com/heimdal/heimdal/tree/heimdal-1.5.3 It's actually about a year old, but they seem to have forgotten to update the project's website. Are there plans to pull 1.5.3 into FreeBSD Current?
