+- Added ability to create new repositories remotely to `rngit`
+- Added latest release management to `rngit`
+- Added download stats to `rngit`

+
+**Release Signatures**
+Release artifacts include `rsg` signature files that can be validated against the RNS release signing identity `<bc7291552be7a58f361522990465165c>` using `rnid`. To verify files, download the `rsg` signatures, make sure they are in the same folder as the release artifact, and run `rnid` signature verification with the release identity as the required signer:
+
+```sh
+rnid -i bc7291552be7a58f361522990465165c -V rns*.whl
+```
+
+The `rnid` utility will then verify the signatures, and display whether it is valid. If the signature cannot be verified, the file has been tampered with and should be thrown very far away in a jiffy.
+
 ### 2026-05-14: RNS 1.2.6
 
 This release adds further improvements to the `rnid` and `rngit` utilities, and includes several bugfixes and other improvements.
