Version 2.17.1

on GitHub

Added

• Add osmium_tags_filter example showing use of tags filter.
• Add Writer::set_header() function to set header after constructing.

Changed

• Various improvements in PBF file reading make it slightly faster and less CPU intensive.
• Since 2.17.0 Osmium will, when reading files, tell the kernel using fadvise that it can remove pages from the buffer cache that are not needed any more. This is usually beneficial, because the memory can be used for something else. But if you are reading the same OSM file multiple times at the same time or in short succession, it might be better to keep those buffer pages. In that case you can set the environment variable OSMIUM_CLEAN_PAGE_CACHE_AFTER_READ to no and Osmium will not call fadvise. Set it to yes or anything else (or not set it at all) to get the default behaviour.
• If the macro OSMIUM_DEFINE_EXPORT is defined, all exception classes used by Osmium will get "tagged as exported" using __declspec(dllexport) when using MSVC or __attribute__ ((visibility("default"))) on other compilers. This is needed in PyOsmium.

Fixed

• Fix integer parser. IDs in OPL files can now be anything between -2^63 and 2^63-1.
