v0.2.16

• Sort converter output by Hilbert distance against the CRS's total bounds instead of by raw WKB byte order.
• Exit with a non-zero exit code when a command reports a failure (e.g. vec validate-schema on an invalid schema) #27
• Keep collection-only properties in the collection metadata when merging collections, e.g. in create-geoparquet and merge. Properties are kept if they have the same value in all source collections.
