Unfortunately, due to ongoing stability concerns that we’re working to address, the patch we announced earlier this week will not be deployed this weekend. While we know how excited you are to play Leona and explore the new balance changes and platform upgrades, the last thing we want to do is introduce these new features into an unstable environment that would degrade the gameplay experience for everyone.

Our current plans include deploying the Leona update early next week.

We’re sorry to delay this update further, but again, adding new content that increases the risk of instability to the server isn’t something we’re prepared to do. Thank you so much for your continued patience as we work through this difficult situation, and thank you for playing League of Legends!"

TL;DR: Leona and patch in EU will be early next week.
