The branch main has been updated by karels: URL: https://cgit.FreeBSD.org/doc/commit/?id=5c594ec0c4d9a69189c47f885287656bb87ede14 commit 5c594ec0c4d9a69189c47f885287656bb87ede14 Author: Mike Karels <karels@FreeBSD.org> AuthorDate: 2023-02-18 18:05:37 +0000 Commit: Mike Karels <karels@FreeBSD.org> CommitDate: 2023-02-18 18:05:37 +0000 13.2R relnotes: numerous additions plus edits Add entries for many remaining "Relnotes: yes" entries in the git log. Add solicited input in many areas. Some additional edits to previous entries, and add a few details. Strengthen recommendation to reboot after installing user software. Format filenames with [.filename]#name#. Updated sample entry with gitref reference.
