Version 1.9.0

Added

• Add area matching to tags-filter. The tags-filter command can now match "areas" using the "a/" prefix. Areas in this sense are all closed ways with 4 or more nodes and all relations with tag "type=multipolygon" or "type=boundary".
• Add --geometry-types option to the export command allowing you to restrict the geometry types written out.
• Also print out smallest node, way, and relation ID in fileinfo command.
• In the renumber command, the start IDs for nodes, ways, and relations can now be set together or separately with the --start-id option. Negative IDs are now also allowed. Also there is a new --show-index function that prints out the ID mappings in the index.
• More tests and updated documentation.
• Add -C, --print-default-config option to the export command writing out the default configuration to stdout.
• New getparents command to get the ways used by specified nodes or relations having specified members.

Changed

• Newest version of libosmium (2.14.2) and protozoro (1.6.3) are now required.
• Calculation of CRC32 in the fileinfo command is now optional. Calculating the CRC32 is very expensive and going without it makes the program much much faster. Use --crc/-c to enable it. It will also be automatically enabled for JSON output to stay compatible with earlier versions of Osmium which might be used in an automated context (you can disable this with --no-crc). It is also enabled if -g data.crc32 is specified. If it is enabled we are using the CRC32 implementation from zlib which is faster than the one from boost we used before. This is possible through some changes in libosmium.
• Treat ways with same node end locations as closed in export command instead of looking at the IDs. This is more consistent with what the libosmium MultipolygonManager does.
• In the export command, the decision whether a way is treated as a linestring or polygon has changed. See the man page for details.
• Create linestring geometries for untagged ways if -n or --keep-untagged option is set. It doesn't matter whether they are closed or not, they are only written out as linestrings.

Fixed

• Show error for ways with less than 2 nodes if --show-errors is set.
• Attributes (such as id, version, timestamp, etc.) can appear in the properties of the output with arbitrary configurable names. These could overlap with tag keys which we don't want. This change removes tags with those keys on the assumption that the names chosen for the attributes are sufficiently different (something like "@id") from normal tag keys that this will not happen very often and those tags are useless anyway.
• Make --(no)-progress option work in sort command.
