Whats New
Fixed:

Cookie removal (not working since Thunderbird version 52).
"Download rest of message" not working if global inbox was used.
Encoding problems for users (especially in Poland) when a file was sent via a folder using "Sent to > Mail recipient" due to a problem in the Thunderbird MAPI interface.
According to RFC 4616 and RFC 5721, passwords containing non-ASCII characters are encoded using UTF-8 which can lead to problems with non-compliant providers, for example office365.com. The SMTP LOGIN and POP3 USER/PASS authentication methods are now using a Latin-1 encoding again to work around this issue.
Shutdown crash/hang after entering an empty IMAP password.

Under some circumstances Thunderbird on Mac will send attachments using the so-called AppleDouble format which can lead to problems with mail servers and recipients.
