In November we merged 9 PRs into OpenMLS. A major change has been the addition of a commit builder in #1675. The commit builder makes creating commits more convenient as you can see in the example below. let message_bundle = alice_group .commit_builder() .propose_adds(Some(bob_key_package.key_package().clone())) .load_psks(provider.storage()) .expect("error loading psks") .build( provider.rand(), provider.crypto(), &alice_signature_keys, |_proposal| true, ) .expect("error validating data and building commit") .stage_commit(provider) .expect("error staging commit"); let (mls_message_out, welcome, group_info) = message_bundle.into_contents(); Merged PRs November 2024 #1687: Clippy fixes #1684: Add validation annotations and a check #1683: ci: Fix coverage #1679: Fixing a few typos in the book #1678: Update README.md ciphersuite names #1676: Fix docs link #1675: Add Commit Builder #1673: Feat: Better error when attempting to decrypt own messages #1672: VerifiableGroupInfo::epoch() added to public API Contributors @franziskuskiefer @kkohbrok @raphaelrobert @josephlukefahr @keks
