fmtconv r20

• primaries: fixed a bug preventing to set all primaries individually without specifying any preset.
• primaries: fixed a bug in the color conversion, thanks to J1Man for having spotted it.

fmtconv r19

• primaries: refined the values for the Adobe Wide gamut and BT.2020 primaries.
• primaries: added DCI-P3, ACES AP0/AP1, S-Gamut, S-Gamut3.Cine, ALEXA and V-Gamut presets.
• transfer: added ACEScc, ERIMM, S-Log2, S-Log3 and V-Log curves.

fmtconv r18

• Added the primaries function to convert between gamuts.
• The “full” range is now closer to what is specified in the standards.
• A recent Vapoursynth is now required because API headers were updated to version 3.1.4.
• transfer: added the Adobe RGB and ProPhoto / ROMM curves.

fmtconv r17

• bitdepth: added “Void and cluster” dithering method and its patsize parameter.
• bitdepth: added floating point implementation for the Ostromoukhov dithering
• bitdepth: added SSE2 optimizations for halftone modes (0, 1 and 8).
• bitdepth: fixed incorrect conversion from float to 8-bit integer using the “fast” modes with SSE2 instruction set.

fmtconv r16

• bitdepth: added support for 11-bit and 14-bit integer input.
• bitdepth: fixed a slight plane inconsistency when dithering grey multi-plane pictures using an error diffusion algorithm.
• matrix2020cl: added SSE2 optimisations for the floating point path.
• resample: sx, sy, sw and sh parameters passed as arrays are now correctly taken into account. Thanks to mawen1250 for the bug report.
• transfer: added the blacklvl parameter.

fmtconv r15

• resample and bitdepth: fixed a bug creating dark lines or weird patterns. Was introduced in r13 while trying to fix the buffer overflow problem. Thanks to feisty2 for spotting it.
• resample: fixed the non-SIMD code path, causing crashes.

fmtconv r14

• matrix: fixed a bug introducing wrong offsets in custom matrix coefficients, thanks to mawen1250 for the report.

fmtconv r13

• matrix: optimized the SSE2 and AVX2 paths for integer data.
• Added cpuopt to some functions, to manually limit the instruction set optimizations.
• Added build files for the unix-like systems, thanks to jackoneill.
• Fixed a buffer overflow bug in the SSE2 and AVX2 code of bitdepth and resample, thanks to jackoneill for reporting it.
• Removed the int16tofloat and floattoint16 temporary functions.
