Features:
Mailspring has been approved for read-write access to the Google People API and you can now manage contacts in Google accounts! Mailspring will ask you to go to Preferences > Accounts and click "Re-authorize" to grant access to this additional permission before editing contacts.
We no longer use is-online and DNS checks to verify that the app is online. Instead, Mailspring checks that it can reach your actual IMAP / SMTP mail servers. #1357, #1731, #1123
Mailspring now supports plaintext mail display and composition! It can be enabled via a new setting, or for a single draft by holding Alt/Option when creating it. Most composer features are disabled in ths mode - for more information, check out #52 (comment).
