bring up to date
Convey information up to the present; also, make one aware of or conform to new ideas, improvements, or styles. For example, Bring me up to date on the test results, or We've been bringing Grandma up to date with a little makeup and some new clothes. The term up to date comes from bookkeeping, where it signifies account entries to the present time. [Late 1800s]
