Hello,
During this cycle Neutron team merged networking-ovn code to Neutron [1]. As a consequence of it we needed to create a new project called: "OVN Octavia provider", which is a provider driver for Octavia. Before it the driver was placed in networking-ovn tree.
Neutron cannot rely on Octavia-lib, so that is why this decision was made.
The code move process to Neutron took some time and we released the OVN Octavia provider driver yesterday - under version 0.1.0. [2].
If you're working on distro packaging - please be aware that the driver is now delivered by a new package. RPM spec in RDO is ongoing: [3].
We are sorry for this late announcement.
