Subject: [RFC v3 7/8] build: use dynamically generated version maps
Date: Tue, 11 Mar 2025 10:56:05 +0100	[thread overview]
Message-ID: <20250311095609.194523-8-david.marchand@redhat.com> (raw)
In-Reply-To: <20250311095609.194523-1-david.marchand@redhat.com>

Switch to always dynamically generate version maps.

As the map files get generated, tooling around checking, converting,
updating etc.. static version maps can be removed.

-This check can be circumvented by defining ``ALLOW_EXPERIMENTAL_API``
