This is a security patch release. It updates Electron to 44.9.1, which distrusts eight eMudhra intermediate certificates whose private keys were compromised. An attacker holding one of those keys could impersonate any mail server or website. (https://emudhra.we-have-a-problem.com/)

Security:

  • Updated Electron to 44.9.1 to block the compromised eMudhra intermediate certificates.
  • On Linux, tray icons are converted with ImageMagick without going through a shell. (#2934)

Bug Fixes:

  • Fixed Mailspring failing to start when the interface language is set to Luxembourgish. (#2954) Thanks @brhellman!
  • Fixed a composer crash when a list item has no list around it. (#2813)
  • Sending a draft now retries the draft lookup once before reporting "draft not found". (#2848)
  • On Wayland, Mailspring now restores the saved window size. (#2961) Thanks @shanelord01!
  • An empty key list in keymap.json now unbinds a command. (#2950) Thanks @brhellman!

Localization:

  • Updated German translations. (#2976) Thanks @Alintya!

Developer:

  • Account-test errors from the sync engine are now reported to Sentry as separate issues. (#2843)
