WhatsApp has completed seven years of existence and has announced through a blog post that in the coming months they would be putting an even greater emphasis on security features and other features to let people stay in touch with each other.
The post also announced that they would be supporting BlackBerry and Nokia only till this year, "As we look ahead to our next seven years, we want to focus our efforts on the mobile platforms the vast majority of people use. So, by the end of 2016, we will be ending support for WhatsApp Messenger on the following mobile platforms".
The platforms that no longer will have WhatsApp post 2016:
BlackBerry, including BlackBerry 10Nokia S40Nokia Symbian S60Android 2.1 and Android 2.2Windows Phone 7.1 While these mobile devices have been an important part of our story, they don't offer the kind of capabilities we need to expand our app's features in the future, added the post.
Further explaining the rational for the decison it said, "But anniversary dates are also an opportunity to look back. When we started WhatsApp in 2009, people's use of mobile devices looked very different from today. The Apple App Store was only a few months old. About 70 percent of smartphones sold at the time had operating systems offered by BlackBerry and Nokia.Mobile operating systems offered by Google, Apple and Microsoft – which account for 99.5 percent of sales today – were on less than 25 percent of mobile devices sold at the time".
This was a tough decision for us to make, but the right one in order to give people better ways to keep in touch with friends, family, and loved ones using WhatsApp. If you use one of these affected mobile devices, we recommend upgrading to a newer Android, iPhone, or Windows Phone before the end of 2016 to continue using WhatsApp, concluded the post.
