Compatibility Issues Between ERPNext v14 (Development) and v15 (Production)

Hello,
I currently have a setup where my development environment is running on ERPNext version 14, while my production environment has been upgraded to version 15. I would like to know if there are any known compatibility issues I should be aware of when developing on v14 and deploying or syncing with a v15 production environment.

Any guidance or advice from those who have experience with a similar setup would be greatly appreciated!

Thank you!
