If you've no issue with current version and not urgently required to update, then just wait till all the plugin you're using compatible with the new version.
Sometimes the new release also has a few bugs and might need us to update again later (i.e 2.6.1 and so on..)
So better to do it when they release the fully stable version.. may be have to wait till a few months..
At least, that's for me..
