WARNING: do not use the github automatically generated source files (Source code (zip) or Source code (tar.gz)), these are not correct.

The Docker images and binaries linked above are built using AVX2 extensions, and require a CPU that supports them, except the "Pre-compiled Binaries For Older CPU Architectures" which should be compatible with any 64-bit architecture (and, since version 2.3.1, support Cactus's pangenome pipeline).

Please subscribe to the cactus-announce low-volume mailing list to receive notice of Cactus release.

This release includes a patched vg and gfaffix
