更新介紹

Push Notifications
JUCE現在支持iOS和Android上的通知。可以從JUCE應用程序發送和接收本地通知，以及從Apple推送通知服務或Google Firebase接收遠程通知。用戶可以直接通過通知與JUCE應用程序進行交互，方法是按下通知中嵌入的按鈕或根據需要輸入文本響應。支持的平台包括iOS 10或更早版本，以及Android O或更早版本（低至Android 4.0.3 Ice Cream Sandwich）。隨附的演示應用程序展示了每個平台上本地通知的可用設置以及接收遠程通知。

CLion Exporter
Projucer現在包含一個CLion導出器，使JUCE用戶能夠在JetBrains最先進的C ++ IDE中編輯和編譯他們的項目。CLion導出器生成一個CMakeLists.txt，可以在MacOS，Windows和Linux上打開。

Analytics Module
JUCE 5.2包含一個新模塊，其中包含的類使您可以更輕鬆地從應用程序中收集分析。新的示例應用程序AnalyticsCollection說明瞭如何使用此新模塊將應用使用信息傳輸到Google Analytics。同時還支持同時登錄其他分析集合端點（如Firebase）。
