ดาวน์โหลด Mailspring 1.24.1

On Linux, Mailspring 1.24.1 fixed accounts being lost after upgrading when the KWallet secret name changed. Mailspring now falls back to the previous secret storage key and re-saves credentials. (#2864) Thanks @LinusDierheimer!
Features:
- Added "Mark All as Read" to the folder context menu, and an option to show unread counts for all folders. Thanks @AnsCodeLab!
- New drafts in a unified inbox now default to the account of the focused thread. Thanks @AnsCodeLab!
- Added a MessageActionMenuItem extension point so plugins can add items to the message "..." menu. Thanks @AnsCodeLab!
Bug Fixes:
- Fixed mail rules breaking when a folder's ID changed right after it was created. Rules now match folders by name when the match is unambiguous.
- Fixed the sidebar not switching from "Drafts" to "Activity" and other perspectives with the same layout.
- Fixed reminders created in the draft UI missing the last reply timestamp, so they never fired.
- Uploading a new signature image no longer overwrites the previous image on Mailspring's servers. Previously, replacing a signature image changed the image in emails you had already sent, and teams sharing a Mailspring ID could overwrite each other's default signature images.
- On Windows, composer and thread popout windows no longer show a second title bar beneath the native one; press Alt in those windows to show the menu bar. Thanks @ejbiker93ss!
- On Windows, the system tray icon is no longer blurry at 125% / 150% and other fractional display scales. Tray icons now ship as multi-size .ico files so Windows can pick an exact-match frame instead of stretching the 16px image.
- Fixed popout windows sometimes opening with the wrong toolbar when a hot window is assigned a window type. Thanks @ejbiker93ss!
- Fixed link and open tracking being lost when moving a draft between accounts.
- When attaching multiple files to a draft, the file order is now preserved.
- Pasting from Excel or OpenOffice now prefers the HTML clipboard content, and pasting several files at once attaches all of them, not just the first.
- Pasted JPEG, GIF, BMP, and WebP clipboard images are now recognized so they stay inline in the composer. Thanks @AnsCodeLab!
- Fixed some hardcoded colors in package stylesheets that did not follow the active theme.
Improvements:
- Emails with an explicit black text color (common in iCloud and Apple Mail signatures) are now shown white on dark background in dark mode, instead of a bright white background. (#2850)
- The folder context menu is now grouped with separators.
- On Windows, keyboard shortcuts are now shown with Ctrl / Alt / Shift instead of mod in the preferences.
Developer:
- The Claude Desktop MCP integration now uses a stdio bridge built into Mailspring instead of relying on npx.
- --spec-directory now resolves relative paths and fails fast when the directory does not exist.
