The popular WhatsApp Messenger application for Symbian devices has been updated to version 2.9.6 recently, being set to provide users with a better experience than before.No official changelog has been provided for the new app release, but we should expect for it to include various minor fixes and enhancements.
In fact, it should be noted that the app has been updated a few times in the past week, jumping from version 2.9.3 to the new one in only several days.
Most probably, the team of developers behind it had been working on making some specific improvements to it, and it might detail them in the not too distant future.
The mobile software is available for devices running under Nokia S60 3rd edition, 5th edition, Symbian^3, Symbian Anna, or Symbian Belle operating system flavors and can be found on this page on Softpedia.
