Release 1.5.0

This release brings quite a lot of improvements. We removed the "experimental" label from the flex output which we introduced in version 1.3.0. There are some small changes you might have to make to your flex configurations, see the Upgrading chapter of the manual for details.

This release also contains a rewrite of the code used to temporarily store OSM data in memory while processing the data in non-slim mode, i.e. when you import data without --slim. It now uses much less memory.

Other changes:

• The multi output which was marked as deprecated in the last versions has now been removed.
• This is the first release that needs a C++14 compiler.
• New cluster table option in the flex config file which allows you to disable clustering of the table data by geometry.
• Do not try to create indexes for flex output tables without id.
• Added flex config example (attributes.lua) showing how to access OSM object attributes (such as timestamp, user name, etc.) from Lua.
• Added a warning if --flat-nodes/-F is used in non-slim mode.
• Report cache memory usage when running with --log-level=debug.
• Report thread number in all log lines when --log-level=debug is set.
• Use trigger to check geometry validity on first import instead of only doing this when copying the data for clustering. In the flex output this validity check is not used any more for point geometries because they are always valid anyway.
• The RapidJSON library is now used and included in the source.
• Now needs libosmium 2.17.0 which is included in the source.
• Lots of internal cleanups and restructurings.
