[tor-talk] mar-tools changelog?

[Cain Ungothep]

Hi guys.

I posted this as a comment in the blog a few days ago, with no answer so
far.

I've been experimenting with manual incremental updates and noticed that
the "mar-tools-linux64.zip" file in the distribution directory changes
between Tor Browser releases (the executables inside the archive also
change).

I've seen it change at least twice between the two most recent releases.
The signatures were good.

Questions:

1. Is the source in the tools being updated or is this some artifact
of the build/distribution system?

2. If the source changes, are you guys doing that or are you just
pulling from Mozilla?

3. Is there a changelog anywhere?

Thanks!
