Riot announced a slight change to their release schedule this morning for two upcoming Labs.

Quote From Riot

Heimerdinger isn't quite finished with his experiment yet so the Single-Player Legends Lab is now coming with Patch 2.1.0.

Labs can be highly volatile so dates are subject to change

 

"Heimerdinger's Madness Lab", which was originally scheduled for February 3rd along side Aphelios's release, will now come out on February 17th. The "Single-Player Legend Lab" takes its place in the February 3rd release.

Also noteworthy is the fact Riot describes the February 3rd patch as 2.1. Previously, they have described even-numbered patches as "big patches" and odd-numbered patches as "small patches" and said that they want to limit balance changes and major card updates to the "big patches". We already know the upcoming timer changes are slated for release in 2.2 which is presumably the February 17th patch. What we don't know is if any pending balance changes will also be delayed until the 17th or if they will be breaking from that structure and including some balance changes in the February 3rd patch. We know we're certainly anxiously awaiting a The Grand Plaza nerf!
