David Smiley commented on LUCENE-5395:
--------------------------------------
I'm moving some point parsing utilities and some specialized distance
calculations (e.g. DistanceUtils.vectorDistance()) from Spatial4j that are only
used by Solr, into Solr.
> Upgrade Spatial4j to 0.4

> Spatial4j 0.4 should be released the week of January 13th; a snapshot is
> published. A longer version of the delta from 0.4 is in
> [CHANGES.md|https://github.com/spatial4j/spatial4j/blob/master/CHANGES.md]
> A couple notable new features are:

> is deprecated.
> * A binary shape codec for reading & writing the shapes to a byte-stream in a
> reasonably compact manner.
