google speed test tell me to Leverage Browser Caching .
I understand this is for images, css, java and that the expiry dates should be set up to a year.
Say that I need to edit my css files or change an image, what's gonna happened if I have the Leverage Browser Caching set up? Nobody will be able to see the changes after the expiry dates?
sorry if this is a dumb question but Im new to WP
