@FlyingNoob -- Do you want to work on it? If not, I would like to take it.

Hey @FlyingNoob and @HydeHunter2. We already have it working on development branch, but we won't really make a new version until Alamofire integration is ready. Sorry for the delay.

[HydeHunter2]

Good. Thanks for saying before I started working on it 👍

[FlyingNoob]

@HydeHunter2 @sunshinejr Thanks for your help

AF 5.0 seems to not be hurried to be released; is it thinkable to have a pre-release of Moya (13.x.x-beta) with beta support of Alamofire 5 ? 🤔

great work everyone on (Rx/Reactive)Moya 👍

@juliengdt yeah... I mean, we _could_ do an alpha release, but there will be breaking changes afterwards with the Alamofire transition for sure. Still, I think this is something that many people would want in the meantime, so I'm gonna try to release it in a few minutes 👍

Alright y'all, 14.0.0-alpha.1 is released. It covers new RxSwift/ReactiveSwift versions. Bear in mind in the next pre-release we would also add Alamofire and probably remove Result as well.
