@ -22,6 +22,8 @@ Changes
- CLI: allow both e.g. '-height' and '--height' (getopt_long_only())
- UPC/EAN: add guard_descent
- Add output_options BARCODE_QUIET_ZONES and BARCODE_NO_QUIET_ZONES
- Allow dummy AI "[]" if GS1NOCHECK_MODE and has data (#204)
- raster.c: improve non-half-integer interpolation performance
Bugs
----

- Suppress some pedantic warnings, props codemonkey82 (#204)
- gs1.c: Allow 0-length AI data if GS1NOCHECK_MODE, props codemonkey82 (#204)
- raster.c: Need ceilf(symbol->height * si) to avoid heap-buffer-overflow;
also ceilf(large_bar_height * si);
also avoid distributive multiplication with floats to lessen chances of
platform variation (#204 ARM-Cortex crash)
- raster/vector.c: use new stripf() func to workaround gcc 32-bit
