Looking through the first few pages of comments hoping to see some sensible comments. Nope. Jagex almost never tells us exact release dates for updates for this very reason. If there is an issue with an update I'd rather it be delayed than released in a buggy broken state. As for informing players so late, it probably took time to trouble shoot the issue to see if it could be pushed out today. Also, social media is probably the fastest way to disseminate information so it probably was released that way to push it out quickly along with the slower main page.
