  "account": "Mozilla and its subsidiary MZLA have announced that Thunderbird will adopt a faster release schedule, moving from monthly to fortnightly updates starting in September. The latest Extended Support Releases (ESR) are the Thunderbird 154 versions, which users can continue to use for a year if they prefer a slower update cycle. The new Thunderbird 154 release includes several new features and improvements, such as Microsoft Graph support for Microsoft 365, better handling of Cryptographic Message Syntax encrypted messages, enhanced drag-and-drop and context-menu copying of messages and attachments, improved attachment previews on macOS, and the ability to minimize Thunderbird to the system tray on desktops. Additionally, Thunderbird 154 offers more than 30 bug fixes and more than 50 security fixes.",
