Updated Mailspring to 1.5.5 which includes new features and bug fixes.
- Mailspring now shows visual previews of PDF, DOCX, XLSX, XLS, CSV, and Markdown attachments. Selecting an attachment in the message view and pressing the space bar or clicking the small "eye" icon shows a preview of the contents in a new window, so you can finally view PDFs, etc. without leaving your Mailbox!
- In dark mode, text in message bodies is no longer black.
- The copy and cut context menu items are disabled when right-clicking a password field.
- The Brazillian Portuguese translation has been improved!
- You can now view Mailspring's open source license and all of it's dependencies' licenses and copyright notices from the menu.
