I would like to apologize for the confusion and issue a correction
regarding the severity of CVE-2026-3833. As discussed in
https://gitlab.com/gnutls/gnutls/-/issues/1803,
it was decided to treat it as Medium,
but I failed to reflect that in the NEWS file and the release announcement.

The line above should state:
>    [GNUTLS-SA-2026-04-29-5, CVSS: medium] [CVE-2026-3833]

Regarding other post-release fixes: if you encounter failures linking
`tests/mini-dtls-fragments`, you might want to consider
