[Unreleased] -------------------------------------------------------------------------------- +### BLAKE3 checksums + +The package manager now uses `b3sum` for creating digests. The change is +backwards compatible, which means that BLAKE3 will slowly replace the SHA256 +algorithm in packages. The `cpt` package in the repository will continue to use +the sha256 until the end of 2021. + +The `checksums` files generated with BLAKE3 has the header `%BLAKE3` which is +used to distinguish digest algorithms. If the file does not include such a +header, it is assumed to be a file created using the SHA256 algorithm. This is +especially handy for keeping the /etc checksums intact. If the package being +built is already installed on the system `cpt` makes sure that the generated +etcsums are also backwards compatible. + + +### Added +- `cpt-checksum` now has the `-s` flag to generate checksums using the SHA256 + digest algorithm. + ### Changed - `cpt-size` has been rewritten to support POSIX `du`, and to support packages with a file count of over 50,000. |
