Hi devs, Here's the latest list of FLIPs under consideration for the 2.4.0 release. They're still tentative: a few of them still need some essential follow-up checks with the authors before we can commit to including them. I've already reached out to the authors through several channels, but a few of them still haven't replied or shared cross-team testing instructions. To improve visibility and unblock progress, I've compiled the outstanding items below. Other interested developers or users are very welcome to jump in and help with the testing — just comment on the linked Jira ticket if you'd like to pick one up.
