Mailspring

This version of Mailspring includes several changes and bug fixes, as well as an update to our Electron core.

• Mailspring now connects to Outlook accounts using OAuth, resolving connection issues for Hotmail, Outlook and some Office 365 accounts.

• The autoconfig database used to identify your IMAP and SMTP settings automatically has been upgraded to reflect changes in provider settings.

• On Windows and Linux, previewing attachments is more robust and works with a wider variety of files. These attachments also have rendered previews in the message view.

• Mailspring allows you to add Medium, GitHub and YouTube links to email signatures created in the app. (#2484) Thanks @sudeephazra!

• Subject lines no longer overflow if they contain single long words (#2485) Thanks @probablykasper!

• The Simplified Chinese translations have been improved - thanks @qiuzhiqian!

Developer:

• Mailspring now uses Electron 30, a recent supported release based on Chromium M124 - thanks to @Phylu for lots of PRs and manual testing that helped us move up three years of versions (v17 => v30) in the last 12 months!

• The Changelog now mentions security contributions by Positive Technologies, Payatu, and Sonar in v1.13.3.

Note: This release does not fix ongoing issues with Gmail OAuth - we are working through Google's revised certification process for continued access to the Gmail API and expect it to be complete in the next two weeks. Thanks to everyone for your patience, their process changed this year.

Happy new year! This is a small update to Mailspring with a few important changes:

• On macOS, long-pressing a key to show it's available subtitutions (eg: e to see é, ê, etc.) now works properly in the email composer. Sorry for the delay fixing this issue, for many non-english speakers on macOS we know it's a core part of your email workflow.

• We now escape subject and participant names in the print modal, ensuring that they render properly for printing.

• We now use DOMPurify to sanitize the content of HTML emails for display. DOMPurify is maintained by a team of security-oriented web engineers and will ensure Mailspring protects you from the widest possible range of XSS attacks and exploits.

This is a patch release that fixes several issues:

• Composition events in Mailspring's composer should work as expected. (Typing modifier keys, such as Option-E followed by E to create É)

• The composer warn about several more invalid recipient errors correctly (thanks @Phylu!)

• Dark-mode tray support on Windows has been improved with new icons (thanks @Phylu!)

• The Linux Snap build no longer requests extraneous permissions (thanks @3v1n0!)

Mailspring 1.13 now runs on Electron 22, completing a migration process we started in 1.12.0!

If you are upgrading from an old version of Mailspring, download and run 1.12.0 first before installing this version. We've moved from keytar to Electron's safeStorage API for securely storing your email passwords, and version 1.12.0 will perform a migration ensuring your passwords are transitioned.

If you're using the snap version of Mailspring, you may find that Mailspring forgets your passwords when you upgrade. I'm very sorry for the hassle this causes - issues with snap containment in version 1.12.0 caused Mailspring to lose many user's passwords during the upgrade process. If this applies to you, you may see password errors and need to:

• Visit Preferences > Subscription and click Setup Mailspring ID and sign back in to your Mailspring account. (You should see an alert at launch that will remind you which email address you'd used for your Mailspring ID)

• Visit Preferences > Accounts and re-authenticate any accounts shown in red that are having connection difficulty.

• On MacOS, the Mailspring icon in the dock now allows you to compose a new message from the context menu. (thanks @Naroh091)

1.10.1 (3/12/2022)

This release fixes a critical issue in 1.10.0 that caused the app to fail to launch for some Windows users. This was caused by upstream changes to our AppVeyor build pipeline that changed the default compilation architecture from ia32 to x64 on Windows.

I'm sorry it took so long to track this down. If you're a Mailspring Pro user and your work was impacted by this update, feel free to email me at [email protected] and I'll credit your account for the quarter as a thank you for choosing Mailspring.
