v0.4.0

What's Changed

This release improves performance and reduces memory requirements:

• Generating a map of the world on a high-end machine (64 cpu/128GB RAM) now takes as little as 47 minutes instead of an hour
• You can now run with as little as 32GB of RAM instead of 128 using --storage=mmap to store temporary data in memory-mapped files

To run this release from Java, download the attached planetiler.jar, or from docker use ghcr.io/onthegomap/planetiler:0.4.0.

There is ongoing discussion about the project in the #planetiler channel on OSM-US slack. If you are interested in joining, get an invite here!
