WhatsApp is receiving a new update for its beta build that bumps up the version number to 2.19.366. Along with various tweaks, this update mainly fixes a serious bug that caused the last version of WhatsApp beta for Android to crash for many users. This bug found in version 2.19.335 has seemingly been fixed in the latest update, along with other notable changes. Apart from this, it has been long rumoured that dark mode will soon be making its way to WhatsApp, but in this new update as well, the feature is nowhere to be found.
The new update for WhatsApp beta is live on the Google Play Store, and if you wish to become a tester then head over to this link to download and install the latest beta version of WhatsApp on your device.
