WhatsApp最近頻頻推出新功能，似乎想對抗早前因轉會潮而崛起的對手Signal。而在近期的5大更新中，WhatsApp亦有著重於確保用戶在個人私隱方面的安全，包括加密雲端備份、一次性訊息等。另外用家亦可在多個裝置中登入，增加使用上的靈活，一齊黎睇睇WhatsApp有咩新功能啦！
加密雲端備份
雖然WhatsApp使用點對點加密以避免用家資料被第三方盜取，但對話備份並無此功能，有安全疑慮。今次WhatsApp便在Android版增加了Beta版雲端加密備份功能，防止第三方讀取用家對話內容。
中途加入群組通話
以往大家一旦錯過群組通話的來電，便無法在中途加入。而新的加入「群組通話」功能讓用家即使無法及時接聽也能再次加入對話或視訊。
以下3個新功能暫時未正式推出，但根據外媒WABetaInfo及朱克伯格與Will Cathcart表示，這些功能將會在未來版本更新。
多裝置登入
除了原本持有號碼的手機外，未來WhatsApp亦將可以在最多4部裝置上同時使用，包括iPad等平板電腦。
消失模式
開啓消失模式（Disappering Mode）後，所有的對話內容、文字與媒體，將會於對話後七日自動刪除，確保私隱。
一次性訊息
一次性訊息與Telegram類似，發出的內容只能讓用家瀏覽一次，之後便會自動銷毀，並不可再次閱讀。
