APIs compatibility NPM 10.6.1 / NCM 7.2.2 and NPM 12.1 / NCM 7.6

Could you please advise whether the APIs configured to work with NPM 10.6.1 and NCM 7.2.2 will work after upgrade to NPM 12.1 and NCM 7.6 or whether there are major changes in API that would prevent this and have you got any documentation on this?

Thanks
