1.14.0

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.

1.13.3

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.

1.13.2

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!)

1.13.1

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.

1.12.0

Features:

• The Windows tray icon styles have been improved, and a new option allows you to opt-out of the red icon style. (Thanks @Phylu)

• Mail rules now support filtering based on the "Reply-to" header. (Thanks @Phylu)

• The "Snooze" UI now allows you to type "600" as a shortcut for for "6:00". (Thanks @ChocoTonic)

Bug Fixes:

• The snooze label is less ambiguous and includes the month and year. (Thanks @Phylu)

Localization:

• British english localizations have been added. (Thanks @danbishop)

• Traditional chinese localizations have been greatly improved. (Thanks @PeterDaveHello)

Developer:

• Mailspring now stores your mail secrets using Electron SafeStorage instead of the deprecated Keytar library thanks to updates by @Phylu. This will allow us to move to a newer version of Electron soon!

• The Snap package now uses core22 and the gnome extension. (Thanks @soumyaDghosh)

1.11.0

Features:

• The "Move to Folder" menu action allows you to press Tab or the "→" key to complete the name of the highlighted folder, which makes it easier to complete a path in long folder hierarchies.

• Mailspring now properly identifies and formats quoted text from Yahoo and AOL email. (Thanks @nzayatz14)

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

• Mailspring's menu bar icon is now red for new mail and blue for unread mail, which makes it easier to spot a new message that needs attention. (#2433, thanks @marivaldojr)

Bug Fixes:

• Contact sync no longer crashes when a contact has no display name (thanks @ww-daniel-mora)

• The help menu now offers the standard MacOS "menu search" feature (Thanks @probablykasper)

• Colons are allowed in URLs and no longer break Mailspring's link highlighting. (thanks @choptastic!)

• The email preview is no longer in some cases in vertical layout (thanks @glenn2223!)

• Updated Italian translations (thanks @andy00087!)

Developer:

• Mailspring now uses a more restrictive Content-Security-Policy that includes object-src none; media-src mailspring:; manifest-src none;. If your plugin packaged media such as sounds, you may need to reference them via the mailspring:// URL syntax (ala 2b75347)

1.10.8

Happy new year! Thanks for your continued support - we're celebrating five years of open-source and the 60th Mailspring release!

Bug Fixes:

New Contributors

1.10.7

• When creating a new IMAP + SMTP account, Mailspring sends a test message through the SMTP gateway to yourself, instead of attempting to send the message to an invalid address.

• When clicking "Unsubscribe", Mailspring verifies that the unsubscribe URL in the email will open in your default web browser.

• Composer recipient warnings are now optional. (Thanks @arhanjain!)
