  "account": "Mozilla's Thunderbird and its subsidiary MZLA have announced that the popular email client will adopt a faster release schedule, moving from monthly updates to fortnightly releases starting in September. This change aims to keep pace with Firefox's accelerated release cadence. The first of these new releases, Thunderbird 154, was recently rolled out alongside Firefox 154. Users who prefer a more stable experience can continue to use Extended Support Releases (ESR), which will remain available for another year. Thunderbird 154 brings several new features to the table, including Microsoft Graph support for Microsoft 365, enhanced message encryption handling, and improved drag-and-drop and context-menu functionality. The release also includes various bug fixes and security patches, bringing the total to over 30 and 50 respectively.",
