It's been over 1 year since a blog post on the Thunderbird blog [0]. Is there any possibility for an update? Maybe something like "All the cool things we worked on in 2016?" (E: I realize 'developer' does not necessarily mean 'part of the Mozilla team developing it/in charge of the blog' but you may have better contact with someone who can get this done than I have. :] )
It was to my understanding that development, outside of security fixes, was more or less halted. Although looking at commits this doesn't seem to be the case [1]. While I use and enjoy Thunderbird, I was also under the impression is was more or less frozen/dead in the water/EOL.
