Snapchat Inc. has released an update to its messaging app and along with it issued an apology for the December 31 breach which exposed details of over 4.6 million users.

Snapchat earlier said that security researchers were responsible for the hack as they disclosed Snapchat’s APIs. However, in today’s blog post, the company said that it was sorry for the security breach. “We are sorry for any problems this issue may have caused you and we really appreciate your patience and support”, wrote Snapchat in a blog post.

Further, the updated apps for Android and iOS will allow users to opt out of the vulnerable Find Friends feature, which was exploited by hackers to scrape off data belonging to millions of users.

“This morning we released a Snapchat update for Android and iOS that improves Find Friends functionality and allows Snapchatters to opt-out of linking their phone number with their username”, noted Snapchat.

Snapchat also revealed that those users who want to use the Find Friends feature will be required to confirm their phone number.
