Thanks @stefano.menci! It clears this up and push me to the direction of using BETA version, but I would love to see a bit more specific answers about important dependencies.
An another topic about LTS version was mentioning that BETA has more issues regarding “changes on the fly” so I would be better to stick to Classic to avoid any changes during the development OR after release. I would most likely go with the open source Anvil once the app is tested and ready for production for most stable and controlled environment.
However, if I pick the BETA to develop, I might go sideways with this… that is why I’m hesitating.
If I just want a quick project it would be a no brainer, but I need to maintain the app for years once it is done and need a stable reliable versions, which won’t change api or other calls.
