v2.0.0-rc.1

This is the first release candidate of the next major version 2.0 of citygml-tools.

The highlights of this release candidate are:

• Full support for CityGML 3.0 and its GML encoding. Although the GML encoding standard is still a draft and not yet published by OGC, work on the XML schemas has been completed and the schemas are stable. So, citygml-tools is an early implementation of the upcoming GML encoding of CityGML 3.0. The previous versions 2.0 and 1.0 of CityGML are still supported as well, of course.
• New upgrade command that allows you to upgrade your existing CityGML 2.0 / 1.0 datasets to CityGML 3.0.
• The to-cityjson and from-cityjson commands now support CityJSON 1.1 in addition to CityJSON 1.0. Moreover, support for the new CityJSONFeature object has been added to allow streaming of large CityJSON datasets.
• citygml-tools is built with the latest release candidate of citygml4j 3.0 for parsing and writing CityGML 3.0 / 2.0 / 1.0 and CityJSON 1.1 / 1.0 datasets.
• The command-line interface has been changed for some commands. Make sure to print the --help of the commands when testing the release candidate.

citygml-tools now requires Java 11 or higher. Note that the release of separate JAR libraries bundling some of its functionalities will be discontinued with version 2.0.
