Subject: [PATCH v2 1/3] update-index doc: v4 is OK with JGit and libgit2
Date: Fri, 18 Aug 2023 16:37:27 -0700 [thread overview]
Message-ID: <20230818233729.2766281-2-gitster@pobox.com> (raw)
In-Reply-To: <20230818233729.2766281-1-gitster@pobox.com>
Being invented in late 2012 no longer makes the index v4 format
"relatively young".
The support for the index version 4 was added to libgit2 with their
5625d86b (index: support index v4, 2016-05-17) and to JGit with
their e9cb0a8e (DirCache: support index V4, 2020-08-10).
Let's update the paragraph that discouraged its use for folks overly
cautious about cross-tool compatibility.
