Subject: [dpdk-dev] [PATCH] doc: alias to experimental tag for stable apis
Date: Wed,  5 Feb 2020 15:17:52 +0000
Message-ID: <1580915872-1686-1-git-send-email-mdr@ashroe.eu> (raw)

When a maintainer is promoting an API to become part of the next major ABI
version by removing the experimental tag, possibly a few releases in advance of
the declaration of the next ABI version. The maintainer may choose to offer an
alias to the experimental tag, as removing the tag before the declaration of the
next major ABI version, would cause an ABI breakage for applications using the
API.
