Does Unity 5.4.3 supports backward compatibility with Unity 5.4.2?

Does Unity 5.4.3 supports backward compatibility with Unity 5.4.2?

I'm currently using Unity 5.4.2 for my video game project, however my friend who assists me in the project uses Unity 5.4.3 instead.
Does Unity 5.4.3 supports backward compatibility with projects made with the previous version, in this case, Unity 5.4.2?
NB: This is the first time I'm asking in Stack Exchange forum. I'm apologize for any mistakes in this question.

Answer 1:

Yes. If you were to update your unity editor to the newer version, it will re-process the project at startup. You should only expect to have problems when upgrading from a much older version than the current one (e.g. Unity 4 to 5) as APIs are revised to reflect major changes in the engine.

@Gnemlock has pointed out the possibility of bugs being introduced when updating to a newer version of Unity. While a noteworthy point, if your friend is successfully working on the project in 5.4.3, it is unlikely that joining him/her is likely to cause you headaches.

@DMGregory has reminded us of the one fundamental truth in these matters: backing up your project is the number one way to update with confidence.
