I'm working on a project where I need to use this library to parse org.locationtech.jts.geom.Geometry to JtsGeometry and vice versa.
However, I face some errors when I try to use some of the methods:

java.lang.NoSuchMethodError: org.locationtech.jts.geom.Polygon.getExteriorRing()Lorg/locationtech/jts/geom/LineString;
        at org.postgis.jts.JtsBinaryWriter.estimatePolygon(JtsBinaryWriter.java:357)
        at org.postgis.jts.JtsBinaryWriter.estimateBytes(JtsBinaryWriter.java:296)
        at org.postgis.jts.JtsBinaryWriter.writeBinary(JtsBinaryWriter.java:106)
        at org.postgis.jts.JtsBinaryWriter.writeBinary(JtsBinaryWriter.java:113)

I found that the root cause of the issue is because the version of jts-core is not up to date.
As of current version publish in Maven it is using jts-core:1.16.1.
Your latest code is using 1.18.1, but I can't find any latest publish in Maven repository.
May I know is there a plan to officially publish the latest version soon?
