Pushed out release 6.1 to all platforms a moment ago. It contains a couple of small but useful fixes:

* Wrestler's health can no longer exceed the max health due to training. (bug report)

* Selecting the Retire option now pops a confirmation screen before ending your career. (bug report)

The next big release will include a random events system, that will greatly improve higher-level play and hopefully make the game overall more unpredictable and fun. Ideally no two careers will ever be the same. For the modders out there: you'll also be able to create your own random events.
