For further documentation and project information, see: https://www.sigsum.org/ /The Sigsum team NEWS for Sigsum tools, v0.12.0 The main change in this release is support for named policies. New features: * Support for named policies. This means that the user can optionally specify a policy name (using the -P option or directly in submitter key file) instead of specifying a policy file. * Support for builtin policies. In this version there are two builtin policies called "sigsum-test1-2025" and "sigsum-test2-2025". * New tool "sigsum-policy" that can be used to list and show available named policies. Documentation improvements: * In doc/sigsum-proof.md, document the correct keyword "size", https://git.glasklar.is/sigsum/core/sigsum-go/-/issues/135, and clarify the description of how to compute the leaf hash. Incompatible changes: * Building now requires go version 1.23 or later.
