1.4.2

Fixes:

• Mailspring no longer attempts CRAM-MD5 SMTP auth instead of PLAIN or LOGIN when both are supported.
  CRAM-MD5 and DIGEST-MD5 require you've exchanged a shared secret with the SMTP server which is almost
  never the case. #620

• Mark as Spam now appears in the right-click dropdown menu for threads.

• The IMAP/SMTP port dropdowns no longer "stick" the first time you change them during setup.

• Mailspring now lets you know if your SMTP server refused to relay a test message during setup.

• Mailspring now correctly supports SMTP accounts that do not require a username or password. #469

• Open and link tracking now work correctly for accounts using Courier IMAP (where sent messages
  do not appear until re-selecting the folder via IMAP.)

Debugging:

• Mailspring now prints descriptive SMTP error strings instead of SMTP error codes in logs.

1.4.1

Fixes:

• Don’t allow shift-U, shift-I, etc. to be menu accelerators that override composer bubbling. This fixes a bug where, with the Gmail shortcuts enabled, typing Shift-U or Shift-I in the composer would mark the message as read.

1.4.0

Mailspring 1.4 adds macOS Touch Bar support and expands the Thread and View menus to include a wider range of functionality previously tied to keybindings but missing from the apps menus.

Mailspring 1.4 also brings a revised welcome screen that separates Office 365 and Outlook and adds presets for Yandex and GMX. The new welcome screens display tips specific to each provider, ensuring that you follow any required steps (like creating an App Password or enabling IMAP.)

Fixes:

• Mailspring now connects to SMTP servers that only support GSSAPI or Kerberos and PLAIN using the PLAIN method rather than trying to use Kerberos and failing. #341

• The "undo send" toast in Mailspring now has a countdown timer, and the undo button has been visually differentiated from the background. #872

• Emails no longer get "stuck" when using undo send in some scenarios. #336

• Undoing a send of an inline reply during the undo-send time window no longer leaves the composer "locked" or re-sends the original draft. #596, #390

• Mailspring no longer throws an exception when parsing quoted text for some emails.

• Removing the last account from Mailspring no longer causes it to return to the "Connect an Account" screen with errors that prevent you from moving forward without restarting the app.

• The print window now warns you if one or more messages were omitted because they were collapsed, and renders properly in the dark theme.

• The default SMTP port for Outlook is now the STARTTLS default and not port 25. #725

1.3.0

Mailspring 1.3 brings an overhauled search bar with powerful autocomplete that makes it easier to create advanced search queries.

• In addition to searching for freeform text and using the Gmail query language (subject:, in:, is:, from:, to:), Mailspring now allows you to search by date using natural language terms like since: "last week" and before: "february 5th". Try combining them with other terms to search a specific time window!

• You can now right-click a thread to search for other threads from that sender or with that subject.

• You can now focus the search bar and conduct searches entirely with keyboard shortcuts (use Escape to exit the search bar!) #960

Mailspring now uses Electron 2.0.2, which delivers some great bug fixes and new features

• Chrome 61, Node 8.9.3, V8 6.1.534.41 with improved performance and lower memory footprints
• Better GTK+ theme support, including support for menu styling
• Better support for Linux desktop notifications
• The app will no longer cancel restart or shutdown

Fixes:

• Mailspring no longer clips some messages containing images incorrectly. #569

• The Reply-To header is now shown when you expand the message headers. #973

• Dropping images onto the composer now reliably inserts them as inline attachments. #822

• Mailspring now correctly opens attachments with filenames containing emoji on Windows.

• Clicking on the open/link tracking "detail dot" now shows individual tracking events correctly. #945

• The Print window no longer contains an incorrect menu bar on Windows. #958

• Signatures with Facebook and Twitter profiles now display the service favicons reliably when viewed in Gmail and Outlook. #968

• Invalid themes no longer "brick" the app - Mailspring will present an alert with the error and offer to revert to the basic theme. (Mailspring-Theme-Starter/issues/1)

1.2.2

Fixes:

• Drafts sent with RTL text now appear correctly justified for recipients. #869

• In the Linux Snapcraft release, app indicator compatibility has been improved by coercing XDG_CURRENT_DESKTOP to Unity (Thanks Martin Wimpress at Canonical!)

• On Linux, clicking on the system tray toggles the visibility of Mailspring's windows instead of always showing them. #650

• On macOS, Mailspring asks if it can move itself to Applications and handles the new app translocation rules in High Sierra correctly.

• Drafts now allow file attachments up to 25MB in size, and the error message has been corrected. #854

• When linking email accounts, the IMAP/SMTP host fields correctly ignore whitespace to avoid connection errors. #876

• Mailspring's sync process no longer crashes when the snooze / reminder actions of more than 200 threads need to be processed at once.

• Mailspring now correctly auto-links email addresses in the composer into mailto: links #814

1.2.1

Fixes:

• Copy / paste now works correctly in message contents and draft fields, correcting a regression in 1.2.0.

• Right clicking in the composer now presents a "Paste and Match Style" option. #655

• The left 50px of "To" field of message headers is now clickable.

• URLs containing the format #/xxxx?a=b are now automatically linked correctly.

• The "learn more" link in the thread sharing modal now links to a public knowledgebase article.

1.2.0

Features:

• Thread Sharing allows you to easily sync an email thread to the cloud and share it using a link. Mailspring automatically syncs new emails that arrive on the thread and anyone with the link can view the thread or download attachments.

Fixes:

• Searching your mailbox using the "in:folder" syntax no longer produces a limited / old set of results when many, many results match.

• The composer cursor no longer gets "stuck" occasionally when typing diatric or multi-key composition characters. #718, #578

• When resetting an account, Mailspring correctly re-fetches open/read receipt and snoozing metadata

• Mailspring now uses Electron 1.8.4.

1.1.5

Fixes:

• Mailspring no longer crashes when trying to connect some IMAP accounts that it cannot resolve to a preset configuration. #739

• Mailspring no longer requires you to manually provide information for IMAP accounts that are aliases of other proivders, like hotmail.it. #736

• An error no longer replaces the composer when an "emoji mark" cannot be found. #685

• When you click a mis-spelled word, Mailspring no longer selects the entire word. #677

• When you send mail, Mailspring no longer puts your hostname in the MIME Message-ID.

• In the composer you can now edit existing links and links don't open by default unless you control-click them. #702, #704, #639

• The colon character (:) no longer breaks automatic link detection. #695

• When you remove an account, Mailspring resets its local cache for that account, removing stored data on disk. #724

• Images with width and height values containing decimals no longer break logic designed to autosize them for display.

Improvements:

• Mailspring now uses Electron 1.8.3, which includes two security improvements.

1.1.4

1.1.4 (2/14/2018)

Fixes:

• Searching in the Sent folder (and other folders assigned mailbox roles) now works reliably.

• Connecting accounts no longer throws SIGABRT / 3221225477 errors in some scenarios. #292

• Connecting accounts no longer fails when the email provider returns non-UTF8 characters in IMAP responses.

• The open tracking pixel now has an alt tag that self-identifies it as a tracking pixel, which prevents messages from Mailspring from being flagged as spam by some providers. #668

• Mailspring no longer registers for the Utility and Development application categories and appears in the mail package category on Debian systems. #673, #678

• On Linux, the tray assets are larger again (48x48px) in an attempt to make them render properly in more distros.

• In the Taiga theme, the selected item in dropdown menus is visible. #674

1.1.3

Improvements:

• When adding an IMAP account, Mailspring now uses the domain's MX records to identify if it can use settings for a common email service to skip the full, complicated IMAP settings screen.

• When adding a Gmail account, Mailspring now uses two-legged OAuth instead of three-legged OAuth which allows it to renew it's access token more rapidly. (Re-authenticate Gmail accounts for this to take effect.)

• Mailspring VACUUM's the SQLite database every two weeks to prevent fragmentation that can eventually ruin performance. Unfortunately, data cannot be read or written during this process and it can take ~2 minutes for a 3GB database, so it is performed at launch with a new progress screen.

Fixes:

• On linux, the system tray icon is smaller (22x22 with 18x18 content vs 32x32)

• In dark themes, quoted text no longer appears a dark purple that is difficult to read.

• Mailspring no longer becomes "blocked" when ingesting a large number of deletions in a mailbox and will no longer attempt to retrieve many, many new messages all at once.

• When changing accounts in the composer the signature correctly updates to the new account's default. #570

• In the message viewer, the "Download All Attachments" button appears if the email contains multiple images. #583

• In the message viewer, inline images specified using a "cid:filename.png@RANDOM"-style URL now render correctly in the message body instead of as attachments. #569

• Threads with only sent emails no longer appear as from "1969" in some places. #508, #457

• The "Local Time" shown in the company sidebar is now correct and updates in realtime.

• On Linux, mailspring.desktop no longer reports that the app is an editor for text/plain #602

• Undo no longer triggers in both the email body and other recently edited text fields at the same time. #613

• Creating a draft no longer clears the conversations's "snippet" in the thread list.

• When printing a thread, Mailspring no longer prints undefined beside particicpants with no name.

• When pasting HTML, Mailspring now correctly preserves links that have other styling. #592

• When using "two pane mode", viewing the same conversation repeatedly will mark any new messages as read. #617

• When sending an email, the word "attachments" in your signature will no longer cause the app to complain about missing attachments. #610

• Mailspring no longer attempts to create the folder Mailspring..Snoozed on providers that include the path delimiter in the IMAP namespace prefix. #634

• When composing an email, Mailspring will display an alert if you need to choose a Drafts folder to send mail. #634

• Mailspring now uses Electron 1.8.2-beta5, which includes stability and security fixes.

• Exporting raw data from the Activity Dashboard now waits for the filesystem buffer to flush, preventing it from writing only some of the email data on slower hard drives.

• Mailspring no longer briefly spawns duplicate sync processes in some scenarios when you have many accounts linked.

• When your mailbox contains emails with the same subject and participants and no Date header, Mailspring now syncs them all instead of syncing them as a single message, which should prevent thrashing

• A subtle multithreading issue has been fixed which could cause your folders to become corrupted and prevent Mailspring from launching.

Memory and Performance:

• Creating a draft is now ~16x faster in scenarios where lots of quoted text is present.

• The undo history of the composer is cleared when you navigate away from a draft, reclaiming memory.

• Completed tasks are purged from the app's task queue more rapidly so performing many, many actions on your mailbox does not cause the application to use more memory.
