[tbb-dev] Are incremental updates working?

I just noticed that my 4.5-alpha-2 update from 4.5-alpha-1 on Linux was 50M instead of 2M, so presumably I did not get the incremental version of the MAR. I don't recall seeing any error messages about the incremental failing, but perhaps I blinked and missed it.

Is this an implementation bug? Or did we just not properly deploy the incrementals for 4.5-alpha-2 on the website correctly in some way?

It looks like https://dist.torproject.org/torbrowser/update_2/4.5-alpha-1-4.5-alpha-2-linu... exists and seems to have sane data in it, so perhaps this is actually a bug?

Are incremental updates working for anyone else?
