LibRaw 0.22.0 Release is just published in our Github repository and this site download section.
This is bugfix-only release with these commits included:

• Limit strcat space in hassy model manipulation
• Version increment; shlib increment: internal ABI has changed
• check panasonic enc8 tile width against image width
• CR3 parser: zero all buffers before fread
• skip memory allocation checks for OWN_ALLOC decoders
• DNG SDK glue: check for memory limits
• raw2image()/dcraw_process() - check for int16 source data present
• Check for correct bayer pattern, pass incorect ones to vng_interpolate
• parse_rollei: zero input string before fgets
• Nikon padded/12bit: no need to calculate padded row size before final raw_width adjustment
• TALOS-2026-2364: Fix for data size calculation integer overflow in float/deflated DNG loader; Check for read results
• Fix for TALOS-2026-2363: avoid integer overflow in allocation size calculation. Also: check for EOF in read loop
• X3F decoder: implemented hard single allocation limit via LIBRAW_X3F_ALLOC_LIMIT_MB define;
  allocation size calculation converted to 64 bit arithm; fix for TALOS-2026-2359
• Fix for TALOS-2026-2358
• Fix for TALOS-2026-2331
• Fix for TALOS-2026-2330
• Sony YCC decoder: check tile size; add +3 bytes to input buffer to avoid possible overrun in huffman decoder
• FP DNG data limit: perform calculations in 64 bit
• Add extra huff_coeff item to handle huff_index==17 with known (zero) value, not externally provided tag value
• use %lld format for timestamp parse/print where appropriate
• nikon coolscan loader: check for EOF
• Initialize olympus lensID bits
• CR3 parser: all file offsets are unsigned/64bit; check current offset against file size
• Add Canon EOS Kiss M2 to camera list
• Check real color count against filters; do not pass really 4-color images to fbdd or advanced demosaic
• Use LIBRAW_EXCEPTION instead of own internal in losslessjpeg.h
• zero input string to avoid compare random stack garbage with tag names
• Check for eof in Pentax tag search loop
• Fuji decoder: initialize allocated buffers
