Hi @mufasa - Yes, it will pull in the updated hotcue and loop changes without having to remove the track from the library. I am checking with the team now to see if that is also possible for Serato. I’ll keep you posted.
Hi @Antchi & @xpander - I am only at liberty to discuss features that have already been announced, that being, Sync Manager. I can confirm there are other big features/improvements that users will greatly appreciate but I cannot specify what those features are or when they will be released.
We promise to inform everyone the moment a new update is available. 
We hope you appreciate all of the effort that went in to 1.3.4 as there was a LOT of backend work so it will feel more solid than previous builds.
