When the part with the "technical" update is wrong then have a look at the changelog of V45.1 dude. There it is explicite told.We've already talked about this, damnit.
Your assumptions are wrong. All of them.
0.46 is a Kate's update
0.45 was a Max's update
There never was a 0.45.2
There were 0.45 and 0.45.1
0.45 was 0.45 update, first part. 0.45.1 was 0.45 update, second part.
There never was a technical update: 0.45 was first part of 0.45 storyline, 0.45.1 was second part of 0.45 storyline.
