Version 2.13.1

Added

• New "blackhole" file format which throws away all data written into it. Used for benchmarking.

Changed

• When reading OPL files, CRLF file endings are now handled correctly.
• Reduce the max number of threads allowed for the Pool to 32. This should still be plenty and might help with test failures on some architectures.

Fixed

• Tests now run correctly independent of git core.autocrlf setting.
• Set binary mode for all files on Windows in example code.
• Low-level file functions now set an invalid parameter handler on Windows to properly handle errors.
• Restore earlier behaviour allowing zero-length mmap. It is important to allow zero-length memory mapping, because it is possible that such an index is empty, for instance when one type of object is missing from an input file as in osmcode/osmium-tool#65. Drawback is that files must be opened read-write for this to work, even if we only want to read from them.
• Use Approx() to compare floating point values in tests.
• Fix broken Item test on 32 bit platforms.
