Hi,

Thank you very much for this release !

Has anyone put the JAR of JTS 1.13 into a public Maven repository ?

JTS 1.13 will definitely end up in a public Maven repo sooner rather than
later, since it's needed for some current work in GeoTools.

I think in the past Michael Bedward has been doing this. Any chance you can
do this again, Michael?

The JTS 1.13 jars (binaries, sources and javadocs) are now available
from Maven Central...

http://search.maven.org/#browse%7C1672573893

The dependency incantation for your pom.xml file is:

<dependency>
    <groupId>com.vividsolutions</groupId>
    <artifactId>jts</artifactId>
    <version>1.13</version>
</dependency>

PS. Many thanks to Martin for this new dose of JTS goodness !

Hurray,

Thanks for this new release and its many improvements,
It will soon find its natural place in OpenJUMP 1.6 release,

Michaël
