I'm running Thunderbird on a Mac that has macOS Sierra 10.12.2 installed. Thunderbird is on the Release channel. Today I received an update to 45.6.0. The message in the bottom panel of the the Thunderbird window had a "Welcome to Daily" title followed by information about the Daily update channel. Was this a result of a packaging error for the update? The "About Thunderbird" window still reports that it's on the Release channel. Thanks. -Ty
