Hello good people and also Yasuo mains,
Recently we've been talking about why we have to replace League's legacy client. We've got a number of highfalutin technical explanations, but it boils down to this: The sooner everyone's using the updated client, the sooner we can start delivering cool new client features.
Last month, we introduced our plan for replacing the legacy client. We've just completed Phase 1 of the plan and begun Phase 2, starting in Oceania. Below is an updated look at the plan.
NOW COMPLETE: Phase 1 - A small group of randomly-selected players from Oceania, Russia, Brazil, and the Latin America servers were automatically upgraded to the new client, although they still had the ability to launch the legacy client from the login screen. No big problems were encountered during this phase.
MONDAY, APRIL 10 IN OCEANIA: Phase 2 - All players in Oceania were automatically upgraded to the updated client, with the legacy client turned off. We've begun Phase 2 in some shards in China and Garena regions as well.
Phase 3 - Assuming Phase 2 goes well, more regions will be automatically upgraded to the updated client, and the legacy client will be retired. This will happen automatically when players launch League without requiring the download of additional files (beyond that of the regular patch for that week). Soon after Phase 3, we'll replace the legacy client with the updated client on all publicly-hosted game download pages.
Phase 4 - We'll automatically remove legacy client files from your machine to free up space.
Note: This gradual rollout will give us time to monitor player feedback and make adjustments in response. We'll alter these plans or delay the rollout if we find that more significant changes are necessary.
That's a good question, imaginary caps-lock person. After each phase, we'll evaluate how the updated client is doing compared to the legacy client. If it's performing at least as well or better than the legacy client, we'll move forward to the next phase. If we see serious problems (like widespread bugs preventing players from getting into games) we'll slow down the client rollout process to address the issue. Removing the legacy client is the most crucial part of this process, and we want to be extra careful about it.
Assuming Phase 2 goes well, the next step is to officially end the client beta in all other regions, enacting Phase 3 and upgrading all clients in all regions. If you've opted into the client beta—as over 90 percent of players worldwide have already done—this process won't affect you beyond removing the "Launch Legacy Client" button from the new client's login screen.
Got questions? We'll stick around in the comments.
