 **The community has agreed on this release, but it is still pending OGC approval.** We are currently working on the process to get it officially OGC approved as soon as possible. The OGC candidate Standard is at [https://docs.ogc.org/DRAFTS/24-013.html](https://docs.ogc.org/DRAFTS/24-013.html). The candidate Standard remains in draft form until it is approved as a Standard by the OGC Membership. Released versions of GeoParquet will not be changed, so if changes are needed for OGC approval, it will be released with a new version number.

 It should be noted what GeoParquet is less good for. The biggest one is that it is not a good choice for write-heavy interactions. A row-based format
 will work much better if it is backing a system that is constantly updating the data and adding new data.
 
-## Roadmap
-
-The goal of 1.0.0 was to establish a baseline of interoperability for geospatial information in Parquet. For 1.0.0
-the only geometry encoding option is Well Known Binary, but there is an option to allow other encodings. The main goal of 1.1.0 will be to incorporate a more columnar-oriented
-geometry format, which is currently being worked on as part of the [GeoArrow spec](https://github.com/geoarrow/geoarrow). Once that gets finalized we will add the option to
-GeoParquet. In general 1.1.0 will further explore spatial optimization, spatial indices and spatial partitioning to improve performance reading spatial subsets.

 ## Versioning
 
 As of version 1.0 the specification follows [Semantic Versioning](https://semver.org/), so at that point any breaking change will require the spec to go to 2.0.0.
