Gave a talk at last month and figured I could publish my recording of it (sorry the audio isn't the best)! Look out for a off-the-cuff talk on open source and life, which I guess is my usual thing *shrug*

Hi 👋 We have a new in the repo 😁 Since object spread is now supported in many browsers, it makes sense using it when transforming spread syntax in JSX. Who wants to add an option for this? Please leave a comment on GitHub!

Also wanted to shoutout the folks at Bloomberg for helping push us to finally land windows CI on travis (long been in the works from appveyor in the past) . Great work even if no PRs were submitted/merged, will enable a lot more contributions in the future!
