Thunderbird 38.4.0 was suppose to be released in early November. Here we are at almost the end of November and still no Thunderbird 38.4.0 release. Reviewing the Status Meeting Notes from the November 17th meeting this build is still ‘in progress’. Also been following the Build Notes for Thunderbird 38.4.0 which currently shows they are the third build (attempt) at releasing Thunderbird 38.4.0, but still running into issues. The next status meeting will be on November 30th and hopefully will provide some insight if there is going to be a 38.4.0 release or wait until mid December 2015 to release 38.5.0 instead.
