As in: really reallllllly close. (Promise.)

Typically we ship updates on a Thursday, so those of you expecting the Jungle Inferno Update to flip live today, you might want to sit down for this next part. If youâre already in a comfortable sitting position, you might want to sit up straighter, because weâre about to tell you weâre delaying a day and we donât want you to twist your lumbar.

Weâre delaying a day. The updateâs almost finished, but itâs a pretty big one, and we wanted another day to get everything ready and stress test it a little more. Our current plan is to release the update early tomorrow. Hereâs a big list of the changes, additions and fixes weâll be shipping tomorrow in the meantime.
