Release Note: https://www.thunderbird.net/en-US/thunderbird/60.0/releasenotes/
Why it should be update:
- Visual Refresh (the new Thunderbird uses the new photon theme used by Firefox)
- Passwords can now contain non-ASCII characters, like international characters, for example áäß, and symbols, for example €§
- Outlook import. Note: Mail, address book and settings need to be imported individually as "Import Everything" currently does not work.
