Yes Pixelmon 3.0.3 has been released. Yes we will be updating shortly! Follow us on twitter (@JuicesPixelmon), or check back here periodically for updates!
Quick reminder that the new 1.7 map will not be released until Pixelmon is updated to 3.1 and supports the new minecraft terrain generation. We're still unsure as to when that will be, but we're hearing that it's not that far off!
