Which rails version to use?

I am planning to update my application’s rails gem version.

Which is better to use,

3.2.11 or 3.2.12?

I heard 3.2.11 has security fixes included. Does 3.2.12 also contain those security fixes and IS 3.2.12 a stable version of rails.

Thanks in advance.

Use 3.2.12 (which has some extra security fixes). Later version will always include security fixes from previous versions.

Non stable versions are explicitly marked as such and won’t be installed unless you ask for them (eg 4.0.0.beta1, release candidates etc.)
