Concerned about Wappler releases and stability of the software

What version of Wappler is stable for production use?
Wappler seems to focus on introducing new features and not stability.
I stumbled into a bug in Wappler 4.4.2 with response.php part of your core Lib.
The bug was fixed by downloading a zip file.
Please advise on how to select the production ready version of Wappler.
Thanks!
