0.45.17? Not 46?

Everyone is talking about 0.46
Today i got 0.45.17 (from .15). What is going on? Changelogs stopped at 45.13

Please see [Rollout Paused] V0.46 Available Now! - Discussion Thread

Due to some teething issues, we have temporarily paused the rollout of v0.46 . We hope to get this out to everyone with in next day or so!
