There has only recently been a new release [0] so there wasn't any need to update the package. I am still planning to maintain the `-bin` variant for my personal setup and would like to not merge that into `photoprism`.
[0]: https://github.com/photoprism/photoprism/releases
devome [1] filed a request to merge photoprism-bin [2] into photoprism

The result of running `pkgstats show photoprism-bin` is 0. And this
package hasn't been updated for a long time.
