What’s New

Changed:
ADD-ON SUPPORT: Restartless add-ons continue to work if their authors have made the necessary minor adjustments. Non-restartless legacy add-ons using XUL overlays are only supported if add-on authors have adapted them, and Lightning/Calendar is the only one we know that has been adapted.
Changed UI when installing add-ons. Restart required for legacy extensions.
Calendar: UI improvements for event dialog.

Fixed:
Print preview not working in Thunderbird version 63 beta.
Various Theme fixes where incorrect colors, backgrounds, etc. were displayed. Folders with new messages not shown in bold on Mac.
Add-on Options menu not working on Mac.
Shift+PageUp/PageDown in Write window.
Saving content of Write windows didn't overwrite existing file.
Issues related to "Edit Template" command.
Gloda attachment filtering.
S/MIME encryption/signing not working in Thunderbird version 63 beta.
Body search/filtering didn't reliably ignore content of tags.
Mails won't get removed from Trash folder using Maildir. Note: Other deletion issues related to Maildir still persist.
If the "Date" header of a message was invalid, Jan 1970 or Dec 1969 was displayed. Now using date from "Received" header instead.
Mailing list address auto-complete enter/return handling.
When sending of a message failed due a security issue, only "unknown error" was displayed. Now more details are given.
"Select All" in mail view not working in Thunderbird version 63 beta Beta 2.
Fixed in Thunderbird 64 beta 2.
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 Latin1 encoding again to work around this issue.
Cookie removal (not working since Thunderbird version 52). Note: Graphical feedback in the removal dialog is still not correct. This will be fixed in the next beta version.
"Download rest of message" not working if global inbox was used.
Shutdown crash/hang after entering an empty IMAP password.

Known Issues
Unresolved:
Double-clicking on a word in the Write window sometimes launches the Advanced Property Editor or Link Properties dialog.
Spellcheck marks disappeared erroneously for words with an apostrophe.
Editing a plaint text draft may display the entire message as quote (in blue).
Chat: Twitter not working due to API changes at Twitter.com (solution forthcoming).
