Mozilla released the next major update for Thunderbird on April 12th, 2016. Thunderbird 45. There are many changes and fixes in this version which can be viewed in the Release Notes. One of the most noticeable changes is the addition of Correspondents column combining Sender and Recipient with an arrow on the left side of the email address. I don’t understand the purpose of this and even more so after reading Bug 36489 which dates back to almost 16-years ago (April 20, 2000). Frankly, I don’t like the change. It’s not the name change which I could use to, but rather adding the arrow. Good news…
